In recent years, internet traffic in the United States has risen significantly. It is estimated that in the United States, internet traffic increased from 40,000-70,000 terabytes/month in 2001 to 3,400,000-4,100,000 terabytes/month in 2011. To support the steep growth in internet traffic, a large amount of computer-related infrastructure has been developed and implemented. One type of infrastructure that has been increasingly utilized is data centers.
Data centers are facilities that house computer systems and associated components for operation therein. Data centers may include computers, data storage devices, servers, telecommunications systems or other related equipment and may be used to manage, store, process and/or exchange digital information and data. The operation of electrical components within data centers for these functions produces a large amount of heat. As such, many data centers have intricate cooling systems designed to cool electrical components so that the components can function effectively.
Operation of electrical components and cooling systems within data centers often requires a large amount of energy. Data center power use can range from several kW to several tens of MW. Data centers may use, for example, as much electricity as a small town to operate. The power density of a data center may also be more than one-hundred times that of a typical office building.
Due to the high power usage of data centers, data centers are also often responsible for high carbon emissions. For example, it is estimated that in 2007 data centers were responsible for 1.5% of the total electricity consumption in the United States. Likewise, data centers were estimated to be responsible for 0.5% of greenhouse gas emissions in the United States in the same year. The amount of greenhouse gas emissions from data centers is also expected to rise in the future. For example, it is projected that greenhouse gas emission from data centers will double from 2007 levels by 2020.
One factor of how much greenhouse gas emission a data center is responsible for is the energy efficiency of the data center. One common measure of data center energy efficiency is power usage effectiveness, or “PUE”. As discussed further below, PUE is the ratio of the amount of total system (e.g., data center) power to the amount of power used by the electronic (e.g., information technology) equipment of the system. The average data center in the United States has a PUE of 2.0.
The present disclosure provides systems for data center cooling and water desalination. In some aspects, the systems include a data center having a water cooling subsystem configured to receive cool water and output warm water and a desalination plant co-located with the data center and configured to receive and desalinate the warm water. Aspects of the invention also include methods for cooling a data center using a water cooling subsystem and desalinating water with a desalination plant that is co-located with the data center.
Systems of the present disclosure, in various instances include a data center having a water cooling subsystem configured to receive cool water and output warm water and a water desalination plant co-located with the data center and configured to receive and desalinate the output warm water. In some embodiments, the cool water is received from an ocean or sea. In some embodiments of the systems, the desalination plant is a reverse osmosis desalination plant.
Systems may include a water intake. The water intake may, in some aspects, be positioned at a depth of 15 m or more in a water source. In some instances, the water intake is positioned below the photic zone in a water source. The systems may also include a water discharge configured for discharging brine from the water desalination plant. The water discharge is, in some embodiments, positioned at a depth of 15 m or more in a body of water (e.g., an ocean or sea). In some embodiments, the body of water in which the water discharge is positioned is the same body of water, e.g., ocean or sea, in which the water intake of a system is positioned.
The power usage effectiveness (PUE) of the data center of the disclosed systems, in some aspects, is 2 or less. In some instances, the PUE of the data center of the disclosed systems ranges from 1 and 1.3. In some instances, the data center and desalination plant of the disclosed systems are configured to produce fewer carbon emissions as compared to the same data center and water desalination plant operating independently. In some versions of the systems, the data center and water desalination plant are configured to use less energy per amount of data-center cooling and per volume of water desalinated as compared to the same data center and water desalination plant operating independently.
The disclosed systems may include a power plant co-located with a data center and a water desalination plant. In some instances, the power plant is operably connected to both of the data center and the water desalination plant. The data center, water desalination plant and power plant may be configured to produce fewer carbon emissions as compared to the same data center, water desalination plant and power plant operating independently. In some versions of the systems, the data center, water desalination plant and power plant are configured to use less energy per amount of data-center cooling and per volume of water desalinated as compared to the same data center, water desalination plant and power plant operating independently.
Also provided by the present disclosure are methods for cooling a data center and desalinating salt water. In some instances, the methods include (1) cooling a data center with a water cooling subsystem comprising a cool water intake and a warm water discharge, wherein the water cooling subsystem is configured to absorb heat produced by the data center; and (2) desalinating warm water received from the warm water discharge at a desalination plant that is co-located with the data center. In some instances, the desalination plant is a reverse osmosis desalination plant.
In some versions of the methods, a water cooling subsystem of a data center is configured to obtain seawater from a cool water intake. In some instances, a cool water intake may be positioned below the photic zone of a water source (e.g., below the photic zone of an ocean or sea). The methods may also include discharging brine from the desalination plant into an ocean or sea, e.g., below the photic zone of an ocean or sea.
In some embodiments, the methods for cooling a data center and desalinating salt water using a data center and water desalination plant produce fewer carbon emissions as compared to the same data center and water desalination plant operating independently. The methods for cooling a data center and desalinating salt water using a data center and water desalination plant may use less energy per amount of data-center cooling and per volume of water desalinated as compared to the same data center and water desalination plant operating independently.
The disclosed methods, in some instances, also include obtaining power to operate a data center and desalination plant from a power plant co-located with the data center and the desalination plant. In some aspects, the methods for cooling a data center and desalinating salt water using a data center, water desalination plant and power plant may produce fewer carbon emissions than the same data center, water desalination plant and power plant operating independently. In some variations, the methods for cooling a data center and desalinating salt water using a data center, water desalination plant and power plant use less energy per amount of data-center cooling or per volume of water desalinated than the same data center, water desalination plant and power plant operating independently.
In some embodiments, the methods include maintaining the PUE of a data center at 2 or less. In some instances, the methods include maintaining the PUE of a data center at a value between 1 and 1.3.

Any recited method can be carried out in the order of events recited or in any other order which is logically possible.
The present disclosure provides systems for data center cooling and water desalination. The systems include a data center having a water cooling subsystem configured to receive and output water (e.g., cool and warm water, respectively) and a desalination plant co-located with the data center and configured to receive and desalinate the output water (e.g., warm water). The term “data center”, as used herein and described in further detail below, refers to a facility configured and/or used for physically housing (i.e., containing within it) one or more computer systems and/or associated components. In some embodiments, data centers include the components therein and manage, store, process and/or exchange digital information and data. As used herein and described in further detail below, the term “desalination plant” refers to a facility configured and/or used for desalinating water. In some embodiments, desalination plants house components for desalinating water. The terms “desalinate” and “desalination”, as used herein, refer to any of several processes to remove an amount of salt and/or other minerals or components from saline water (i.e., water that contains a concentration of at least one dissolved salt). In some embodiments of the disclosed systems, desalination is removing an amount of salt and/or other minerals or components from saline water so that the water is fit for consumption by a living organism (i.e., a living organism may consume the water and thereby maintain a healthy hydration level and/or a living organism may consume the water without the water having a detrimental effect on the organism's health). In some embodiments of the disclosed systems, desalination makes water potable (i.e., fit to drink; drinkable). In some embodiments the living organism is a “mammal” or “mammalian”, where these terms are used broadly to describe organisms which are within the class mammalia, including the orders carnivore (e.g., dogs and cats), rodentia (e.g., mice, guinea pigs, and rats), and primates (e.g., humans, chimpanzees, and monkeys). In some embodiments, the living organism is a human. The term “human” may include human subjects of both genders and at any stage of development (e.g., fetal, neonates, infant, juvenile, adolescent, adult), where in some embodiments the human subject is a juvenile, adolescent or adult. In some embodiments of the disclosed systems, desalination is removing an amount of salt and/or other minerals or components from saline water so that the water is fit for a specific purpose (e.g., irrigation).
As summarized above, systems as described herein include a data center co-located with a desalination plant. The terms “co-locate”, “co-located” and “co-locating”, as used herein refer to placing two or more things in proximity (i.e., within a certain distance). In some aspects of the disclosed systems, co-located units may be located such that they share one or more common aspects (e.g., facilities or components such as specific systems or machinery). In some aspects, co-located units may be located, for example, within 0.1 m; 1 m; 10 m; 100 m; 1,000 m; 10,000 m; or 100,000 m of one another. In some embodiments, co-located units are two or more facilities located on immediately adjacent or abutting areas or parcels of land. In some embodiments, co-located units are two or more facilities located on the same area of land. In some versions of the disclosed systems, co-located units may be located such that they are in fluid communication (i.e., the units are configured such that at least one fluid may move and/or flow between the units). In some variations of the disclosed systems, co-located units are located such that they share one or more of the components described herein (e.g., a water cooling subsystem). In some embodiments of the disclosed systems, co-located units may be located such that they are electrically connected (i.e., connected by at least one conductive material) and/or share at least one electrical component. In some instances, co-located units are located such that their location allows them to be more energy-efficient (i.e., use less energy for the same amount of productivity) than the units would be if they were located in a different position (e.g., a greater distance away from each other). In various embodiments, co-located units are located such that their location allows them to produce fewer carbon emissions (e.g., carbon dioxide emissions) or have a smaller carbon footprint than the units would if they were located in a different position (e.g., a greater distance away from each other). In some versions, co-located units are located such that their location allows them to minimize potential pollutants (e.g., thermal pollution) emitted therefrom. In some embodiments of the disclosed systems, co-located units may be located such that they are operably connected.
By “operably connected”, as used herein, is meant connected in a specific way (e.g., in a manner allowing water to move and/or electric power to be transmitted) that allows the disclosed system and its various components to operate effectively in the manner described herein. For example, a power plant operably connected to a data center may allow electricity to flow (i.e., be transmitted along at least one conductive material) between the power plant and the data center such that the energy required to operate the data center would be at least partially obtained from the power plant.
In some instances, and as depicted by the diagram of
Various aspects of the embodiments of the systems shall now be described in greater detail below.
Data Center
Embodiments of the disclosed systems include one or more data centers. As noted above, the term “data center” refers to a facility configured and/or used for physically housing (i.e., containing within it) one or more computer systems and/or associated components. In some embodiments, data centers include the components therein and manage, store, process and/or exchange digital information and data.
Data centers may include computers, data storage devices, servers (e.g., web servers, database servers and/or application servers), switches, routers, vaults, load balancers, racks, wire cages or closets and/or related equipment. Data centers may include redundant data communications connections, backup or redundant power supplies, security devices, and/or fire suppression systems. In some instances, data centers include data storage systems and/or telecommunications systems. Some versions of data centers are used for providing application services or management for various types of data processing (e.g., intranet, web hosting internet). In some embodiments, data centers are used, for example, to operate and manage one or more carriers' telecommunication network, provide data center applications directly to one or more carriers' customers and/or provide hosted applications for one or more third parties to provide services to customers. Embodiments of data centers include data centers that are within one or more buildings. In some aspects, data centers occupy one or more rooms of a building, one or more floors of a building or an entire building.
In some instances, data centers are electrically powered. For example, some embodiments of data centers consume electricity to operate. Power draw for data centers may range from a few kW (e.g., one, two, three, four or five kW) to several tens of MW (e.g., one, two, three, four, five, six, seven, eight or nine tens of MW) for larger facilities. In some aspects of data centers, the data centers have power densities of more than one-hundred times that of an average office building. In some embodiments of data centers, electricity costs are the primary operating expense of the data center and may account for 10% or more of a data center's total cost of ownership.
Embodiments of data centers are operably connected to at least one power source (e.g., one or more power plants, as described herein). Some versions of data centers include a power source (e.g., a source from which electrical power may be obtained). Power sources, in some embodiments, generate or obtain power from renewable energy sources. Renewable energy sources include, for example, one or more systems or devices configured to convert one or more forms of energy (e.g., solar, wind, wave, biofuel, biomass, tidal and/or geothermal energy) to another form (e.g., electric power). For example, a power source may be one or more solar panels.
In some embodiments, data centers use an amount of energy for each function performed by the data center or components thereof. For example, data centers or systems including data centers may use a specific amount of energy per amount of data center cooling. In some aspects, data centers or systems including data centers have a degree of energy efficiency that may be quantified as the power usage effectiveness (PUE) of the data center or system including a data center (e.g., a PUE of 1.0; 1.1; 1.2; 1.3; 1.4; 1.5; 1.6; 1.7; 1.8; 1.9; or 2.0). The PUE is the ratio of the total power entering a system (e.g., a data center and optionally, a desalination plant and/or a data center power source, such as a power plant) to the power used by the computer systems and/or associated components (e.g., information technology equipment) within the system (e.g., the data center). In various aspects, a PUE is the inverse of the data center infrastructure efficiency (DCIE). In some versions, systems (e.g., data centers) have a PUE of 2.0 or less, such as 1.9 or less, e.g., 1.8, 1.7, 1.6, 1.5, 1.4, 1.3, 1.2 or 1.1 or less (e.g., a PUE ranging from 1.0 to 2.0). In some embodiments, a system (e.g., a data center) has a PUE ranging from 1.0 to 1.3. In some instances, a system, (e.g., a data center) has a PUE of or about 1.0, where a PUE of or about 1.0 is a PUE near, and greater than, 1.0 (e.g., 1.01 or 1.02 or 1.03 or 1.04 or 1.05 or 1.06 or 1.07 or 1.08 or 1.09 or 1.1 or 1.15 or 1.2 or 1.25 or 1.3 and/or within the range 1.01 to 1.30). In determining the PUE of data centers of the invention, one may factor in a component that represents the reduced energy used by the desalination plant in desalinating the warm water output of the data center cooling subsystem. Any convenient protocol for factoring in this component into the PUE determination may be employed. For example, the reduction in energy used by the desalination plant resulting from co-location of the desalination plant with the data center (and particularly by using the warm output water from the data center) may be added to the amount of energy input into the data center which is used by the computer systems and/or associated components (e.g., information technology equipment). One particular formula that may be employed is:
PUE=Total Facility Power/IT Equipment Power
Where total facility power includes cooling and lighting, as well as anything that is not considered a computing device, whereas IT equipment is computing devices A PUE of 1.0 is ideal meaning that all the power is going to computing devices. A PUE of less than 2.0 is desirable, such as less than 1.5, and including less than 1.1, e.g., below 1.01. By performing the cooling with cool sea water, then only the cost of pumping the water adds to total facility power.
In some embodiments, data centers and/or power sources of data centers produce carbon emissions. In some aspects, data centers (e.g., data centers operating independently) produce an amount of carbon emissions for each function or portion of a function performed by the data center or components thereof.
Data centers, in some instances, produce heat. As such, some versions of data centers include environmental control systems (e.g., one or more air conditioning units) for controlling at least a portion of the environment with a data center. In some aspects, environmental control systems include the water cooling subsystems described herein. In some aspects, environmental control systems include temperature control systems that are configured to heat and/or cool at least a portion of the data centers. In some instances, environmental control systems include humidity control systems that are configured to control the amount of humidity in at least a portion of the data centers. In some aspects, environmental control systems include pressure control systems that are configured to control the pressure level in at least a portion of the data centers. Some versions of environmental control systems are configured to maintain at least a portion of a data center and/or computer related equipment therein at a temperature between 16° C. and 24° C. (e.g., 17° C.; 18° C.; 19° C.; 20° C.; 21° C.; 22° C. or 23° C.) and/or within a humidity range of 40%-55% and/or with a maximum dew point of 15° C.
In various instances, and as noted above, data centers include one or more water cooling subsystems. The phrases “water cooling subsystem” and “water cooling subsystems”, as used herein, refer to an interconnected structure located at least partially within a data center that is configured to cool at least one component (e.g., a server) or portion (e.g., a room) of the data center. Where desired, the interconnected structure of a water cooling subsystem includes one or more components (e.g., pipes and/or containers) configured to carry water from one location (e.g., the location of the intake) to another location. In some embodiments, water cooling subsystems include a warm water discharge and/or output. In some embodiments, water cooling subsystems are water-tight except for an intake for receiving water into the subsystems and warm water discharge and/or output for discharging water out of the subsystems. The water cooling subsystem, in some instances, may be configured to receive water (e.g., cool water) from an ocean and/or sea and/or river and/or lake and/or groundwater source and/or other water source.
The term “water”, as used herein, refers to the chemical compound having the chemical formula H2O. Water may also be salt water (e.g., seawater) and as such may include one or more components (e.g., salts) dissolved therein. Salt water (e.g., seawater) may have a salinity of about 3.5% (35 g/L, or 599 mM) (e.g., a salinity of 3.4% to 3.6% or 3.1% to 3.8%). Water may also be in the form of a liquid and/or gas.
Water, as described in the application, may also have a variety of different temperatures. By “cool” water, as used herein, is meant water that has a lower temperature than “warm” water, as described herein. In some aspects the temperature of cool water is within the range 1° C. to 35° C. For example, in some instances the temperature of cool water is within one of the following ranges: 1° C. to 10° C.; 11° C. to 20° C.; 21° C. to 30° C.; 31° C. to 35° C.; 12° C. to 19° C.; 13° C. to 18° C.; 14° C. to 17° C.; 15° C. to 16° C.; 1° C. to 20° C.; 2° C. to 19° C.; 3° C. to 18° C.; 4° C. to 17° C.; 5° C. to 16° C.; 6° C. to 15° C.; 7° C. to 14° C.; 7° C. to 13° C.; 8° C. to 12° C.; or 9° C. to 11° C. In some aspects, the temperature difference between cool water and warm water may range from 1° C. to 99° C. For example, the temperature difference between cool water and warm water may be 1° C.; 2° C.; 3° C.; 4° C.; 5° C.; 6° C.; 7° C.; 8° C.; 9° C.; 10° C.; 11° C.; 12° C.; 13° C.; 14° C.; 15° C.; 16° C.; 17° C.; 18° C.; 19° C.; 20° C.; 21° C.; 22° C.; 23° C.; 24° C.; 25° C.; 26° C.; 27° C.; 28° C.; 29° C.; 30° C.; 31° C.; 32° C.; 33° C.; 34° C.; 35° C.; 36° C.; 37° C.; 38° C.; 39° C.; 40° C.; 41° C.; 42° C.; 43° C.; 44° C.; 45° C.; 46° C.; 47° C.; 48° C.; 49° C.; 50° C.; 51° C.; 52° C.; 53° C.; 54° C.; 55° C.; 56° C.; 57° C.; 58° C.; 59° C.; 60° C.; 61° C.; 62° C.; 63° C.; 64° C.; 65° C.; 66° C.; 67° C.; 68° C.; 69° C.; 70° C.; 71° C.; 72° C.; 73° C.; 74° C.; 75° C.; 76° C.; 77° C.; 78° C.; 79° C.; 80° C.; 81° C.; 82° C.; 83° C.; 84° C.; 85° C.; 86° C.; 87° C.; 88° C.; 89° C.; 90° C.; 91° C.; 92° C.; 93° C.; 94° C.; 95° C.; 96° C.; 97° C.; 98° C.; or 99° C. The temperature difference between cool water and warm water may also be, for example, at least 1° C.; at least 2° C.; at least 3° C.; at least 4° C.; at least 5° C.; at least 10° C.; at least 15° C.; at least 20° C.; at least 25° C.; at least 30° C.; at least 35° C.; at least 40° C.; or at least 50° C., such as 1° C. or more; 2° C. or more; 3° C. or more; 4° C. or more; 5° C. or more; 10° C. or more; 15° C. or more; 20° C. or more; 25° C. or more; 30° C. or more; 35° C. or more; 40° C. or more; or 50° C. or more, where an upper limit to the above ranges is, in some instances, 100° C., such as 75° C. In some aspects, cool water may have a temperature within one of the above listed ranges when the cool water enters and/or exits a component of the systems described herein (e.g., the water intake). In some aspects, cool water may have the same temperature as the water source from which the cool water is taken. For example, cool water may have the same temperature as that of the portion of ocean or sea surrounding (e.g., a location at or within a distance of 1 m and/or 10 m and/or 100 m and/or 1000 m) one or more elements of the system disclosed herein (e.g., a water intake and/or a water discharge). In some aspects of the disclosed systems, the cool water is received into the systems from an ocean or sea. In some instances, the temperature of cool water increases and/or decreases as the water progresses through the disclosed systems.
By “warm” water, as used herein, is meant water that has a higher temperature than “cool” water, as described herein. In some aspects the temperature of warm water is within the range 36° C. to 100° C. For example, in some instances the temperature of warm water is within one of the following ranges: 36° C. to 40° C.; 41° C. to 50° C.; 51° C. to 60° C. 61° C. to 70° C. 71° C. to 80° C. 81° C. to 90° C.; 91° C. to 99° C. 40° C. to 45° C.; 46° C. to 50° C.; 51° C. to 55° C.; 56° C. to 60° C.; 61° C. to 65° C.; 66° C. to 70° C.; 36° C. to 60° C.; 37° C. to 59° C.; 38° C. to 58° C.; 39° C. to 57° C.; 40° C. to 56° C.; 41° C. to 55° C.; 42° C. to 54° C.; 43° C. to 53° C.; 44° C. to 52° C.; 45° C. to 51° C.; 46° C. to 50° C.; or 47° C. to 49° C. As noted above, in some instances, the temperature difference between cool water and warm water may range from 1° C. to 99° C. For example, the temperature difference between cool water and warm water may be, at least 1° C.; at least 2° C.; at least 3° C.; at least 4° C.; at least 5° C.; at least 10° C.; at least 15° C.; at least 20° C.; at least 25° C.; at least 30° C.; at least 35° C.; at least 40° C.; or at least 50° C. In some aspects, warm water may have a temperature within one of the above listed ranges when the warm water enters and/or exits a component of the systems described herein (e.g., the water discharge). In some aspects, warm water may have a higher temperature than the water source from which the cool water is taken. For example, warm water may have a higher temperature than that of the portion of ocean or sea surrounding (e.g., a location at or within a distance of 1 m and/or 10 m and/or 100 m and/or 1000 m) one or more elements of the system disclosed herein (e.g., a water intake and/or a water discharge). In some embodiments, the temperature of warm water increases and/or decreases as the water progresses through the disclosed systems.
In some aspects, the water cooling subsystem may be configured to carry cool water to at least one location in a data center (e.g., a location where heat is produced by the data center) where the cool water is heated and thereby converted to warm water. Cool water may be heated and converted to warm water within a heat exchange element of a water cooling subsystem, which is described in further detail below. The water cooling subsystem may also, in some instances, be configured to carry warm water away from one location in a data center (e.g., the location of a heat exchange element) to another location (e.g., a location outside a portion of the data center which contains one or more computer systems and/or associated components). Where desired, the water cooling subsystem is configured to carry heat energy away from one or more computer systems and/or associated components that generate heat energy by allowing generated heat energy to be transferred to water (e.g. cool water) within the water cooling subsystem (e.g., within a heat exchange element of the water cooling subsystem) and thereafter, transferring the heated water (e.g., warm water) away from the position within the data center where it was heated. By transferring water within a data center and thereby cooling one or more computer systems and/or associated components within the data center, the water cooling subsystem optimizes the operation of the systems and/or components by providing an environment in which the systems and/or components may effectively operate.
In some instances, water cooling subsystems include a heat exchange element. In some embodiments, heat exchange elements are configured to cool one or more locations and/or components within a data center. For example, heat exchange elements may be configured to allow an exchange of heat produced by a data center at a first location to a medium (e.g., air and/or water) and thereafter transfer the heated medium to a second location so that the first location of the data center and/or components at the first location are cooled. In some aspects, heat exchange elements are configured such that a medium (e.g., cool water) may be channeled into the heat exchange element (e.g., from a first portion of the water cooling subsystem) and/or a medium (e.g., warm water) may be channeled out of the heat exchange element (e.g., to a second portion of the water cooling subsystem).
In some aspects, a heat exchange element is an air conditioning system (e.g., one or more air conditioning units). In some instances, heat exchange elements are configured to cool air around (e.g., in the same room of a data center as data center components) components (e.g., electrical components) of the data center which produce heat. In some instances, heat exchange elements are configured to allow the transfer of heat from air (e.g., air heated by data center components) around (e.g., in the same room of a data center as data center components) components (e.g., electrical components) of the data center which produce heat to cool water. Such an exchange will result in the air being cooled and the water being warmed (e.g., to warm water). Accordingly, in some aspects, cool water is heated to warm water within the heat exchange element. In some instances, heat exchange elements are configured to remove air that has been heated by components of a data center from the area of the data center (e.g., room) in which the components are located.
In some embodiments, heat exchange elements are one or more channels (e.g., channels having a large interior and/or exterior surface area) physically integrated with components of a data center (e.g., electronic components which produce heat). Where desired, heat exchange elements are configured such that water may flow through them and thereby transfer heat away from the data center components. In some versions, the heat exchange element is operably connected to the remainder of the water cooling subsystem at one or more locations (e.g., one, two, three, four or five locations). In some aspects, the heat exchange element is composed of the same materials as the remainder of the water cooling subsystem or different materials. Examples of heat exchange elements that may be utilized either wholly or partially in connection with the disclosed systems are provided by U.S. Pat. Nos. 6,374,627; 8,0094,30; 7,525,207; 7,347,058; 8,004,832; 7,810,341; 7,808,780; 6,574,104; 6,859,366; 8,157,626; 7,881,057; 6,980,433; 6,945,058; 6,854,284; 6,834,512; 6,775,997; 6,772,604; 8,113,010; 8,276,397; and 8453,471 as well as those described in U.S. Published Patent Application Nos. 20120138259; 20110225997; 20110059687; 20100107658; and 20100146996; the disclosures of each which are incorporated by reference herein.
As noted above, in some embodiments, water cooling subsystems include a warm water discharge and/or warm water output. In various instances, warm water discharges are operably connected (e.g., attached in a water-tight manner) to desalination plants and/or power plants. In some versions, warm water discharges are part of the same structure as the coupling components described herein. Where desired, warm water discharges expel warm water out of a water cooling subsystem and/or into a water source or body of water. In some embodiments, warm water discharges include one or more openings through which warm water may move (e.g., flow). In some embodiments, a warm water discharge is a pipe and may be made of the same and/or different materials and/or types of materials as the water intakes described herein. In some versions, a warm water discharge is positioned inside or outside a portion of the data center which contains one or more computer systems and/or associated components. The water cooling subsystem, in some embodiments, includes a water intake. In some aspects, the water intake includes one or more openings (e.g., holes, gaps and/or slits) in the water cooling system configured to receive water (e.g., cool water) into the water cooling subsystem. For example, the water intake may be one or more pipes having one or more (i.e., one, two, three, four, five, six, seven, eight, nine, or ten or more) openings (e.g., an open end) positioned within a body of water such that water may flow into the one or more pipes. In some embodiments, a water intake or an opening therein is shaped as a circle, rectangle, square, slit, polygon, quadrilateral, oval, semi-circle, or other shape. In some instances, a water intake or an opening therein may have a single defined radius of symmetry. In some versions, a water intake or an opening therein may radii of curvature lying within a single plane (e.g., a vertical plane or a horizontal plane).
In some embodiments, water intakes (e.g., one or more openings in water intakes) are configured to intake or otherwise have an amount of water (e.g., seawater) move through them in a set time period (e.g., a minute or hour or day). For example, water intakes may be configured to intake up to: 5,000 L/day; 10,000 L/day; 15,000 L/day; 20,000 L/day; 25,000 L/day; 30,000 L/day; 35,000 L/day; 40,000 L/day; 45,000 L/day; 50,000 L/day; 55,000 L/day; 60,000 L/day; 65,000 L/day; 70,000 L/day; 75,000 L/day; 80,000 L/day; 85,000 L/day; 90,000 L/day; 95,000 L/day; 100,000 L/day; 150,000 L/day; 200,000 L/day; 250,000 L/day; 300,000 L/day; 350,000 L/day; 400,000 L/day; 450,000 L/day; 500,000 L/day; 550,000 L/day; 600,000 L/day; 650,000 L/day; 700,000 L/day; 750,000 L/day; 800,000 L/day; 850,000 L/day; 900,000 L/day; 950,000 L/day; 1 million L/day; 5 million L/day; 10 million L/day; 20 million L/day; 30 million L/day; 40 million L/day; 50 million L/day; 60 million L/day; 70 million L/day; 80 million L/day; 90 million L/day; 100 million L/day; 110 million L/day; 120 million L/day; 130 million L/day; 140 million L/day; 150 million L/day; 160 million L/day; 170 million L/day; 180 million L/day; 190 million L/day; 200 million L/day; 220 million L/day; 240 million L/day; 260 million L/day; 280 million L/day; 300 million L/day; 400 million L/day; 500 million L/day; or 1 billion L/day. Water intakes may also be configured to intake more than 1 billion L/day. Water intakes, in some embodiments, may be configured to intake an amount of water in any of the ranges: 5,000 L/day to 1 billion L/day; 5,000 L/day to 1 million L/day; 5,000 L/day to 100 million L/day; 5,000 L/day to 20,000 L/day; 20,000 L/day to 40,000 L/day; 40,000 L/day to 60,000 L/day; 60,000 L/day to 80,000 L/day; 80,000 L/day to 100,000 L/day; 100,000 L/day to 120,000 L/day; 120,000 L/day to 140,000 L/day; 140,000 L/day to 160,000 L/day; 160,000 L/day to 180,000 L/day; 180,000 L/day to 200,000 L/day; 200,000 L/day to 250,000 L/day; 250,000 L/day to 300,000 L/day; 3000,000 L/day to 350,000 L/day; 100,000 L/day to 200,000 L/day; 200,000 L/day to 300,000 L/day; 300,000 L/day to 400,000 L/day; 400,000 L/day to 500,000 L/day; 500,000 L/day to 600,000 L/day; 600,000 L/day to 700,000 L/day; 700,000 L/day to 800,000 L/day; 800,000 L/day to 900,000 L/day; 900,000 L/day to 1 million L/day; 1 million L/day to 20 million L/day; 20 million L/day to 40 million L/day; 40 million L/day to 60 million L/day; 60 million L/day to 80 million L/day; or 80 million L/day to 100 million L/day. In some aspects, intakes are configured such that the amount of water moving (e.g., flowing) through an intake may be variable within a time period (e.g., one minute, one hour, one day, one month, one year).
In some aspects, the water intake or a portion thereof is positioned outside the portion of the data center containing the one or more computer systems and/or associated components. For example, in some variations, the water intake is positioned outside the building housing the one or more computer systems and/or associated components. Where desired, the intake is in fluid communication with at least one portion of the water cooling subsystem located inside the portion of the data center containing the one or more computer systems and/or associated components wherein cool water is heated (e.g., heated to warm water).
Embodiments of the water cooling subsystems include a water intake positioned at a depth of 15 m or more in a water source. Some variations of the water cooling subsystems include a water intake and/or at least one opening therein (e.g., an opening at the end of the intake furthest from the portion of the data center housing computer systems and related components) positioned at a depth of 1 m or more; 2 m or more; 3 m or more; 4 m or more; 5 m or more; 6 m or more; 7 m or more; 8 m or more; 9 m or more; 10 m or more; 11 m or more; 12 m or more; 13 m or more; 14 m or more; 16 m or more; 17 m or more; 18 m or more; 19 m or more; 20 m or more; 25 m or more; 30 m or more; 35 m or more; 40 m or more; 45 m or more; 50 m or more; 60 m or more; 70 m or more; 80 m or more; 90 m or more; 100 m or more; 200 m or more; and/or 300 m or more in a water source, where an upper limit in some instances may be 5000 m or less, such as 2500 m or less, e.g., 1000 m or less. In some aspects, water cooling subsystems include a water intake and/or at least one opening therein positioned below and/or within a particular zone (e.g., euphotic and/or disphotic, and/or aphotic zone and/or benthic zone) in a water source. Water cooling subsystems, in some versions, include a water intake and/or at least one opening therein positioned below the photic zone in a water source.
In some aspects wherein a water intake is positioned at a particular depth within a water source (e.g., a depth of 15 m or more), its center (e.g., the center-most point of a water intake) and/or the top edge (e.g., the edge or portion closest to the surface of the water) of the water intake and/or the bottom edge (e.g., the edge or portion furthest from the surface of the water) of the water intake is positioned at that particular depth below the surface of the water. In some instances, a water intake positioned at a particular depth within a water source may have an opening wherein the center of the opening (e.g., the center-most point of a circular and/or square opening) and/or the top edge (e.g., the edge or portion closest to the surface of the water) of the opening and/or the bottom edge (e.g., the edge or portion furthest from the surface of the water) of the opening is positioned at that particular depth below the surface of the water.
Embodiments of water cooling subsystems, and in some versions water intakes, include one or more filters configured for purifying water. In some instances, at least one filter is located at one or more openings in the intake and/or at the end of the intake furthest from the portion of the data center housing the computer systems and/or related equipment. Where desired, a filter is positioned within the portion of the data center housing the computer systems and/or related equipment.
Water cooling subsystems and/or water intakes thereof may, in various embodiments, be composed of one or more materials or one or more types of materials. Examples of materials that the water cooling subsystems of the disclosed systems may be composed of include polymers, ceramics, metals, glasses and/or a combination thereof. In some instances, the water cooling subsystems are not composed of metal or material that is subject to corrosion (e.g., corrosion by rust). In some embodiments, water cooling subsystems are composed of plumbing materials. For example, water cooling subsystems may be composed of polyvinyl chloride (PVC) pipes and/or joints and one or more adhesives for fastening the pipes in a water-tight manner. Where appropriate, one or more materials of the water cooling subsystems may be rigid. In some aspects, one or more materials of the water cooling subsystems may be flexible (e.g., one or more rubber tubes or hoses). However, these examples of materials are not limiting and the materials of the water cooling subsystems may be any material, or combination of materials, having the structural and chemical properties necessary to function in the disclosed systems as described herein.
The water cooling subsystem, in various instances, includes a pump. In some embodiments, a pump is a means for causing water to move through water cooling subsystems and/or other components (e.g., water intakes; water discharges and/or desalination plants), as described herein. In some variations, a pump causes water to move unidirectionally or bidirectionally through water cooling subsystems and/or other components (e.g., water intakes; water discharges and/or desalination plants), as described herein. In some instances, a pump is electrically powered and/or fossil fuel powered and/or powered by another means. In some aspects, a pump is operably connected to a power source (i.e., the power source of the data center), as described herein. In some aspects, a pump may be operably connected to a power plant. In particular versions, tides, and/or a pump powered by tides, cause water to move through the water cooling subsystems and/or other components (i.e., desalination plants) described herein. In some embodiments, one or more pumps are located within data centers and/or desalination plants, as described herein. In some embodiments, one or more pumps are located outside data centers and/or desalination plants, as described herein.
In particular aspects, water cooling subsystems include one or more valves within the subsystems for controlling the movement of water through the system. In some embodiments, the valves are controllable (e.g., configured to be opened and/or closed in reaction to a designated signal or action). Where desired, each valve is individually controllable (e.g., a valve may be opened and or closed while other valves are not). In some embodiments, the one or more valves include electrical components and may be configured to receive an electronic signal from a controller operably connected thereto.
Water Desalination Plant
The disclosed systems, in some instances, include one or more desalination plants. As used herein, the term “desalination plant” refers to a facility configured and/or used for desalinating water. In some embodiments, desalination plants house components for desalinating water.
In some variations, desalination plants operate by distillation (e.g., vacuum distillation). Desalination plants may be configured to boil water (e.g., salt water) and collect water (e.g., water vapor) having a significantly reduced or eliminated salt concentration. Desalination plants, in some instances, boil water at less than atmospheric pressure. In some versions, desalination plants operate by multistage flash distillation. As such, desalination plants may be configured to operate by one or more processes that distill water (e.g., seawater) by flashing an amount of water into steam in multiple stages of concurrent heat exchangers. In some instances, desalination plants using distillation (e.g., vacuum distillation) employ heated water (e.g., warm water) in one or more processes. Desalination plants may be configured to desalinate water by using both distillation and reverse osmosis processes.
In some embodiments, desalination plants of the disclosed systems are reverse osmosis desalination plants. In some aspects, reverse osmosis desalination plants use pressure and/or one or more semipermeable membranes to desalinate water. In some versions of reverse osmosis desalination plants, water is passed through one or more semipermeable membranes in order to remove salt and/or minerals and/or other impurities therefrom. In some instances, the efficiency of a desalination process of a reverse osmosis desalination plant is higher if the temperature of the water input (e.g., saltwater) into the desalination process is higher. In various embodiments, a desalination process of a reverse osmosis desalination plant uses less energy per volume of water desalinated if the temperature of the water input (e.g., saltwater) into the desalination process is higher.
By desalinating water, in some aspects, desalination plants may produce desalinated water and/or brine (e.g., both desalinated water and brine). As used herein, the term “brine” refers to a solution discharged from a desalination plant. In some aspects, brine may be a solution (e.g., a concentrate) including salt (e.g., sodium chloride) and water. In some versions, brine has a salt concentration in the range 3.5% to 26%. In some embodiments, brine includes one or more of the impurities removed from water during desalination (e.g., minerals or other components). In some instances, brine may include residues of chemicals used to treat (e.g., clean) a desalination plant.
Embodiments of desalination plants include at least one filter configured for purifying water. In some aspects, the at least one filter of the water intakes includes one or more semipermeable membranes.
In some instances, desalination plants are configured such that an amount of water may move through the plants. In some embodiments, desalination plants are configured such that an amount of water may move through the plants by traveling through an interconnected desalination structure of operably connected pipes and/or containers. The interconnected desalination structure of operably connected pipes and/or containers, in some variations, is composed of the same and/or different materials or types of materials as the water cooling subsystems and/or water intakes described above. In particular embodiments, the interconnected desalination structure of operably connected pipes and/or containers of a desalination plant is connected to and/or includes a coupling component for receiving water from a water source and/or a water discharge for discharging water from the desalination plant.
In some versions, desalination plants include one or more valves for controlling the movement of water through the desalination plant (e.g., through an interconnected desalination structure of operably connected pipes and/or containers within a desalination plant). In some embodiments, the valves are controllable (e.g., configured to be opened and/or closed in reaction to a designated signal or action). In some aspects each valve is individually controllable (e.g., a valve may be opened and or closed while other valves are not). In some instances, the one or more valves include electrical components and may be configured to receive an electronic signal from a controller operably connected thereto.
In various aspects, a desalination plant is configured such that water can move (i.e., flow) into the plant from a water source (e.g., a water cooling subsystem). In some embodiments, the water source of a water desalination plant is the water cooling subsystem of a data center (e.g., a co-located data center). As such, where desired, water desalination plants may be configured to receive warm water from water cooling subsystems or a portion thereof (e.g., a warm water discharge or output) and/or another source (e.g., a power plant). In some embodiments, water desalination plants are configured such that warm water received into a desalination plant is used in one or more water desalination processes therein.
In some versions, desalination plants include one or more coupling components. Coupling components may be configured for connecting to and receiving water from a water cooling subsystem. In some aspects, one or more coupling components are positioned within a desalination plant and/or within a data center and/or between a desalination plant and a data center (e.g., at the interface of a desalination and data center). In some instances, the one or one or more coupling components are a pipe or a series of pipes for providing fluid communication between the desalination plant and data center. In some embodiments, the one or more coupling components are operably connected (e.g., attached in a water-tight manner) to a warm water discharge or output of a data center. The one or more coupling components may be operably connected to a water intake (e.g., a cool water intake), as described herein. As such, water (e.g., cool water) may be added to the warm water passing out of the water cooling subsystem of a data center before it enters a desalination plant. The one or more coupling components may be operably connected to a water discharge (e.g., a warm water discharge), as described herein. As such, all or a portion of the water channeled to flow through the coupling component may be channeled to flow into a water source and all or a portion of the water channeled to flow through the coupling component may be channeled to flow into the water desalination plant. The one or more coupling components may also be operably connected to one or more other coupling components.
In some embodiments, coupling components are configured to have an amount of water (e.g., seawater) move (e.g., flow) through them per time period (e.g., minute or hour or day). For example, coupling components may be configured to have up to the following amounts of water move (e.g., flow) through them: 5,000 L/day; 10,000 L/day; 15,000 L/day; 20,000 L/day; 25,000 L/day; 30,000 L/day; 35,000 L/day; 40,000 L/day; 45,000 L/day; 50,000 L/day; 55,000 L/day; 60,000 L/day; 65,000 L/day; 70,000 L/day; 75,000 L/day; 80,000 L/day; 85,000 L/day; 90,000 L/day; 95,000 L/day; 100,000 L/day; 150,000 L/day; 200,000 L/day; 250,000 L/day; 300,000 L/day; 350,000 L/day; 400,000 L/day; 450,000 L/day; 500,000 L/day; 550,000 L/day; 600,000 L/day; 650,000 L/day; 700,000 L/day; 750,000 L/day; 800,000 L/day; 850,000 L/day; 900,000 L/day; 950,000 L/day; 1 million L/day; 5 million L/day; 10 million L/day; 20 million L/day; 30 million L/day; 40 million L/day; 50 million L/day; 60 million L/day; 70 million L/day; 80 million L/day; 90 million L/day; 100 million L/day; 110 million L/day; 120 million L/day; 130 million L/day; 140 million L/day; 150 million L/day; 160 million L/day; 170 million L/day; 180 million L/day; 190 million L/day; 200 million L/day; 220 million L/day; 240 million L/day; 260 million L/day; 280 million L/day; 300 million L/day; 400 million L/day; 500 million L/day; or 1 billion L/day. Coupling components may also be configured to have more than 1 billion L/day of water move (e.g., flow) through them. Coupling components, in particular embodiments, may be configured to have an amount of water move through them wherein the amount is in any of the ranges: 5,000 L/day to 1 billion L/day; 5,000 L/day to 1 million L/day; 5,000 L/day to 100 million L/day; 5,000 L/day to 20,000 L/day; 20,000 L/day to 40,000 L/day; 40,000 L/day to 60,000 L/day; 60,000 L/day to 80,000 L/day; 80,000 L/day to 100,000 L/day; 100,000 L/day to 120,000 L/day; 120,000 L/day to 140,000 L/day; 140,000 L/day to 160,000 L/day; 160,000 L/day to 180,000 L/day; 180,000 L/day to 200,000 L/day; 200,000 L/day to 250,000 L/day; 250,000 L/day to 300,000 L/day; 3000,000 L/day to 350,000 L/day; 100,000 L/day to 200,000 L/day; 200,000 L/day to 300,000 L/day; 300,000 L/day to 400,000 L/day; 400,000 L/day to 500,000 L/day; 500,000 L/day to 600,000 L/day; 600,000 L/day to 700,000 L/day; 700,000 L/day to 800,000 L/day; 800,000 L/day to 900,000 L/day; 900,000 L/day to 1 million L/day; 1 million L/day to 20 million L/day; 20 million L/day to 40 million L/day; 40 million L/day to 60 million L/day; 60 million L/day to 80 million L/day; or 80 million L/day to 100 million L/day. In some aspects, the amount of water moving (e.g., flowing) through a coupling component is variable within a time period (e.g., one minute, one hour, one day, one month, one year).
A desalination plant, in some embodiments, is configured such that brine moves (i.e., flows) out of the desalination plant through a water discharge. In some instances, desalination plants are operably connected to (e.g., in fluid communication with) water discharges, as described herein.
A desalination plant, in various aspects, is configured such that desalinated (e.g., water having a low salt concentration) moves out of the desalination plant through a water expulsion aspect. The water expulsion aspect may be one or more pipes. The water expulsion aspect may also be configured to transport the desalinated water to a location where the desalinated water may be used and/or stored. The water expulsion aspect may, in some aspects, also be configured to transport the desalinated water to a location from which the desalinated water can be further transported.
Desalination plants, in some versions, include a pump. In some embodiments, a pump is a means for causing water to move through desalination plants and/or other components (e.g., data centers; water cooling subsystems; water intakes; and/or water discharges), as described herein. In particular instances, a pump causes water to move unidirectionally or bidirectionally through desalination plants and/or other components, as described herein. In some embodiments, a pump is electrically powered and/or gasoline powered and/or powered by another means. In some aspects, a pump is operably connected to a power source (i.e., the power source of the data center), as described herein. In some instances, a pump may be operably connected to a power plant. In particular embodiments, tides, and/or a pump powered by tides, cause water to move through the desalination plants and/or other components (i.e., data centers) described herein. In some embodiments, one or more pumps are located within data centers and/or desalination plants, as described herein. In some versions, one or more pumps are located outside data centers and/or desalination plants, as described herein.
Where desired, desalination plants include electrical components. For example, desalination plants may include temperature and/or lighting control systems as well as electrical systems for desalinating water. In some aspects, desalination plants (e.g., desalination plants operating independently) use an amount of energy (e.g., electrical energy) for each volume of water desalinated.
Where desired, desalination plants may be operably connected to at least one power source (e.g., one or more power plants and/or the power source of a data center, as described herein). Some embodiments of desalination plants include a power source (e.g., a source from which electrical power may be obtained). Power sources, where appropriate, and as described above, generate or obtain power from renewable energy sources. In some aspects, desalination plants may be operably connected (e.g., electrically connected) to a data center or one or more of the components thereof.
In some versions, desalination plants and/or power sources of desalination plants produce carbon emissions. In some aspects, desalination plants (e.g., desalination plants operating independently) produce an amount of carbon emissions for each function or portion of a function performed by the desalination plant or components thereof. For example, in some embodiments, desalination plants produce a certain amount of carbon emissions per volume of desalinated water produced.
The disclosed systems, in some instances, include one or more desalination plants co-located with one or more data centers. As noted above, some embodiments of the disclosed systems include desalination plants that are configured to receive and desalinate warm water output from a data center (e.g., a co-located data center). Some variations of the disclosed systems that include desalination plants configured to receive and desalinate warm water output from a data center are thereby configured to produce fewer carbon emissions as compared to the same data center and water desalination plant operating independently (e.g., a data center and water desalination plant not connected in a manner such that water or electricity may travel from one to the other). Also, in some instances, the disclosed systems include desalination plants that are configured to receive and desalinate warm water output from a data center and are thereby configured to use less energy (e.g., electrical energy) as compared to the same data center and water desalination plant operating independently (e.g., a data center and water desalination plant not connected in a manner such that water or electricity may travel from one to the other).

The word “cooling” is used broadly and generically to refer to lowering the temperature of an aspect (e.g., a data center or a portion of one or more components therein) or a portion of an aspect (e.g., a portion of a data center that is heated by one or more components of the data center). As such, in some embodiments, cooling a data center with a water cooling subsystem having a cool water intake and a warm water discharge includes lowering the temperature of at least a portion of the data center or one or more components of the data center using the water cooling subsystem.

As noted above, in some embodiments, data centers, desalination plants and/or their power sources produce carbon emissions. In some aspects, data centers and/or desalination plants (e.g., desalination plants operating independently) produce an amount of carbon emissions for each function or portion of a function performed by the desalination plant or components thereof. For example, in some variations, desalination plants produce a certain amount of carbon emissions per volume of desalinated water produced.
Also, as noted above, co-locating and/or operably connecting a data center and desalination plant can reduce their overall carbon emissions. As such, in some instances, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center produce fewer carbon emissions as compared to operating the same data center and water desalination plant independently (e.g., a data center and water desalination plant not connected in a manner such that water or electricity may travel from one to the other). In some variations, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center include producing a smaller carbon footprint as compared to the same data center and water desalination plant operating independently.
As noted above, in particular instances, data centers and/or desalination plants use an amount of energy for each function performed by the data center and/or desalination plant or components thereof. For example, data centers may use a specific amount of energy per amount of data center cooling.
Also, as noted above, co-locating and/or operably connecting a data center and desalination plant can improve their overall energy efficiency. As such, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center may use less energy per amount of data-center cooling and per volume of water desalinated as compared to the same data center and water desalination plant operating independently (e.g., a data center and water desalination plant not connected in a manner such that water or electricity may travel from one to the other). In some versions, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center include cooling a data center and desalinating water in a more energy-efficient manner as compared to operating the same data center and water desalination plant independently.
In particular embodiments, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center include maintaining the PUE (e.g., the PUE of the data center) at a particular value, such as 2.0 or less, e.g., 1.9, or less, 1.8 or less, 1.7 or less, 1.6 or less, 1.5 or less, 1.4 or less, 1.3 or less, 1.2 or less, 1.1 or less, where the particular value at which the data center is maintained may vary, e.g., a PUE of 1.0; 1.1; 1.2; 1.3; 1.4; or 1.5. In some instances, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center include maintaining the PUE (e.g., the PUE of the data center) within a particular range (e.g., below 2; between 0 and 2; or between 1 and 2). For example, in some aspects, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center include maintaining the PUE (e.g., the PUE of the data center) between 1 and 1.3 or at a value greater than 1 but approaching 1 (e.g., 1.1; 1.15; 1.2; 1.25; or 1.3).
In some versions, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center include co-locating and/or operably connecting a data center, desalination plant and power plant. As such, in some embodiments, the disclosed methods include obtaining power to operate the data center and the desalination plant from a power plant co-located with the data center and the desalination plant.
As noted above, in some instances, data centers, desalination plants and/or power plants produce carbon emissions. In some aspects, power plants (e.g., power plants operating to produce electric power independently) produce an amount of carbon emissions for each function or portion of a function performed by the power plant or components thereof. For example, power plants may produce a certain amount of carbon emissions per amount of electrical power produced.
Also, as noted above, co-locating and/or operably connecting a data center, desalination plant and power plant can reduce their overall carbon emissions. As such, in various instances, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center that include obtaining power to operate the data center and the desalination plant from a power plant co-located with the data center and the desalination plant produce fewer carbon emissions as compared to operating the same data center, water desalination plant and power plant operating independently. In some versions, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center by obtaining power to operate the data center and the desalination plant from a power plant co-located with the data center and the desalination plant include producing a smaller carbon footprint as compared to the independent operation of the same data center, water desalination plant and power plant.
As noted above, co-locating and/or operably connecting a data center, desalination plant and power plant can improve their overall energy efficiency. As such, in some instances, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center that include obtaining power to operate the data center and the desalination plant from a power plant co-located with the data center and the desalination plant use less energy per amount of data-center cooling or per volume of water desalinated than the same data center, water desalination plant and power plant operating independently (e.g., operating while not operably connected). In some versions, the disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center by obtaining power to operate the data center and the desalination plant from a power plant co-located with the data center and the desalination plant include cooling a data center, desalinating water and/or producing or obtaining power in a more energy-efficient manner as compared to operating the same data center, water desalination plant and power plant independently.
The disclosed methods of cooling a data center and desalinating salt water at a desalination plant co-located with the data center by obtaining power to operate the data center and the desalination plant from a power plant co-located with the data center and the desalination plant, in various embodiments, include maintaining a PUE (e.g., the PUE of the data center) at a particular value (e.g., any PUE value listed herein, or another PUE value) or within a range of particular values (e.g., any range of PUE values listed herein, or another range of PUE values).
The subject systems and methods may be used to cool data centers and desalinate water. As described herein, in some aspects, the disclosed systems may be configured to operate in a way that is more effective than operating components of the systems independently. For example, a data center co-located with and operably connected to a desalination plant may allow the data center and/or desalination plant to use less energy per amount of data-center cooling and/or per volume of water desalinated as compared to the same data center and water desalination plant operating independently. Similarly, the methods disclosed herein may allow the operation of a data center and/or desalination plant to use less energy per amount of data-center cooling and/or per volume of water desalinated as compared to methods of operating the same data center and water desalination plant independently. Furthermore, the disclosed systems and methods relating to a data center co-located with and operably connected to a desalination plant and a power plant may allow the data center and/or desalination plant and/or power plant to use less energy per amount of data-center cooling and/or per volume of water desalinated and/or per amount of energy produced as compared to the same data center, water desalination plant and power plant operating independently.
The disclosed systems and methods may also operate in such a way as to minimize the impact of data centers, desalination plants and/or power plants on the surrounding environment. For example, operation of the disclosed systems or utilization of the disclosed methods may result in a data center and water desalination plant that produce fewer carbon emissions or less thermal pollution as compared to the same data center and water desalination plant operating independently. Also, operation of the disclosed systems or utilization of the disclosed methods may result in a data center, water desalination plant and power plant that produce fewer carbon emissions or less thermal pollution as compared to the same data center, water desalination plant and power plant operating independently.
Accordingly, the subject systems and methods may be applied to minimize the amount of energy used by data centers, desalination plants and/or power plants. The subject systems and methods may also be applied to minimize the amount of carbon emissions from data centers, desalination plants and/or power plants. By enhancing efficiency of operation and minimizing carbon emissions, the disclosed systems and methods are useful to minimize costs associated with data centers, desalination plants and/or power plants and to promote the quality of the surrounding environments.
