The present disclosure is related to systems, methods, apparatuses, and techniques for generating water using waste heat.
Many different systems, apparatuses, and devices produce heat during operation. For example, heat may be produced by engines, household devices (e.g., refrigeration systems, air conditioners, stoves, gas heaters, etc.), generators, fuel cells, and/or many other systems, apparatuses, and devices. In many cases, the heat of can be a by-product that is produced during the operation of these systems, apparatuses, and devices. The heat generated by these systems, apparatuses, and devices is typically released into the atmosphere in the vicinity of the systems, apparatuses, and devices, and is not used for any purpose. There exists a need for systems, methods, and apparatuses that advantageously make use of waste heat.

As explained in greater detail below, in many embodiments, system 300 can make available water to a user of system 300. In these or other embodiments, system 300 can generate water, such as, for example, using native heat generated by a heater and/or waste heat generated by a waste-heat-generating-system. In many embodiments, the water made available to the user of system 300 can comprise the water generated by system 300.
Generally, therefore, system 300 can be implemented with hardware and/or software, as described herein. In some embodiments, at least part of the hardware and/or software can be conventional, while in these or other embodiments, part or all of the hardware and/or software can be customized (e.g., optimized) for implementing part or all of the functionality of system 300 described herein.
System 300 comprises a water generating unit 301. In some embodiments, system 300 also can comprise a waste-heat-generating-system 302.
Further, water generating unit 301 can comprise a waste-heat-receiving-heat exchanger 303, a desiccation device 304, a condenser 305, a blower 306, and a circulator 307. Further, desiccation device 304 can comprise an adsorption zone 311, a desorption zone 312, a desiccant element 313, and an actuator 314.
In many embodiments, water generating unit 301 can comprise a heater 308. In these or other embodiments, water generating unit 301 can comprise a condenser heat exchanger 309, a water generating unit control system 310, a reservoir 315, a filter 316, and/or a filter 317. In other embodiments, heater 308, condenser heat exchanger 309, water generating unit control system 310, reservoir 315, filter 316, and/or filter 317 can be omitted.
Waste-heat-receiving-heat exchanger 303 can be coupled to desiccation device 304, desiccation device 304 can be coupled to condenser 305, and condenser 305 can be coupled to waste-heat-receiving-heat exchanger 303. Further, when water generating unit 301 comprises heater 308, heater 308 can be coupled to condenser 305 and desiccation device 304.
In some embodiments, when water generating unit 301 comprises heater 308, heater 308 can be coupled in series with waste-heat-receiving-heat exchanger 303, such as, for example, between condenser 305 and waste-heat-receiving-heat exchanger 303 or between waste-heat-receiving-heat exchanger 303 and desiccation device 304 (as illustrated in
In many embodiments, circulator 307 can operably move and repeatedly cycle one or more regeneration fluids from waste-heat-receiving-heat exchanger 303 and/or heater 308, to desiccation device 304 to condenser 305 and back to waste-heat-receiving-heat exchanger 303 and/or heater 308 (e.g., in a closed loop). Waste-heat-receiving-heat exchanger 303, heater 308 (when implemented), desiccation device 304, and condenser 305 can be coupled together by any suitable conduits configured to transfer the regeneration fluid(s) among waste-heat-receiving-heat exchanger 303, heater 308 (when implemented), desiccation device 304, and condenser 305. Exemplary regeneration fluid(s) can comprise humid air, one or more supersaturated or high relative humidity gases (e.g., a relatively humidity greater than approximately 90%), one or more glycols, one or more ionic liquids, etc.
Circulator 307 can comprise any suitable device configured to move the regeneration fluid(s) from waste-heat-receiving-heat exchanger 303 and/or heater 308, to desiccation device 304 to condenser 305 and back to waste-heat-receiving-heat exchanger 303 and/or heater 308. For example, in some embodiments, circulator 307 can comprise a pump.
In many embodiments, desiccation device 304 can receive the regeneration fluid(s) at desorption zone 312. In many embodiments, after the regeneration fluid(s) are received at desorption zone 312, the regeneration fluid(s) can be moved to condenser 305. In some of these embodiments, the regeneration fluid(s) can be moved to one or more additional desiccation devices before being moved to condenser 305, as explained below.
In many embodiments, blower 311 can move a process fluid (e.g., humid air) to desiccation device 304. For example, in some embodiments, desiccation device 304 can receive the process fluid at adsorption zone 311. Further, blower 311 can move the process fluid through desiccation device 304 (e.g., through adsorption zone 311). In some embodiments, after the process fluid is received at adsorption zone 311, the process fluid can be exhausted to the atmosphere around (e.g., adjacent to) water generating unit 301.
Blower 311 can comprise any suitable device configured to move the process fluid to desiccation device 304. For example, in some embodiments, blower 311 can comprise a pump.
In many embodiments, actuator 314 can operably move and repeatedly cycle desiccant element 313, or portions thereof, between adsorption zone 311 and desorption zone 312 to capture (e.g., absorb and/or adsorb) water from the process fluid received at adsorption zone 311 and desorb water into the regeneration fluid(s) received at desorption zone 312. For example, in some embodiments, desiccant element 313 can be disposed on a wheel located partially at adsorption zone 311 and partially at desorption zone 312. Accordingly, in these embodiments, portions of desiccant element 313 can be simultaneously located at adsorption zone 311 and at desorption zone 312, such as, for example, so that desiccant element 313 can simultaneously capture (e.g., absorb and/or adsorb) water from the process fluid received at adsorption zone 311 and desorb water into the regeneration fluid(s) received at desorption zone 312. Meanwhile, actuator 314 can operably rotate the wheel so that continuously changing portions of desiccant element 313 are located at adsorption zone 311 and at desorption zone 312 when actuator 314 rotates the wheel.
In some embodiments, desiccant element 313 can comprise any suitable material or materials configured such that desiccant element 313 can capture (e.g., absorb and/or adsorb) and desorb water. For example, the material(s) of desiccant element 313 can comprise one or more hygroscopic materials. In many embodiments, exemplary material(s) for desiccant element 313 can comprise silica, silica gel, alumina, alumina gel, montmorillonite clay, one or more zeolites, one or more molecular sieves, activated carbon, one or more metal oxides, one or more lithium salts, one or more calcium salts, one or more potassium salts, one or more sodium salts, one or more magnesium 25 salts, one or more phosphoric salts, one or more organic salts, one or more metal salts, glycerin, one or more glycols, one or more hydrophilic polymers, one or more polyols, one or more polypropylene fibers, one or more cellulosic fibers, one or more derivatives thereof, and one or more combinations thereof.
In some embodiments, desiccant element 313 can comprise any suitable form or forms configured such that desiccant element 313 can capture (e.g., absorb and/or adsorb) and desorb water. For example, desiccant element 313 can comprise a liquid form and/or a solid form. In further embodiments, desiccant element 313 can comprise a porous solid impregnated with one or more hygroscopic material(s).
In some embodiments, desiccant element 313 can be configured to capture (e.g., absorb and/or adsorb) water at one or more temperatures and/or pressures and can be configured to desorb water at one or more other temperatures and/or pressures. In some embodiments, desiccant element 313 can be implemented with material(s) and/or form(s), and/or can be otherwise configured such that desiccant element 313 does not capture (e.g., absorb and/or adsorb) one or more materials toxic to humans, pets, and/or other animals.
In many embodiments, condenser 305 can extract water from the regeneration fluid(s) received at condenser 305, such as, for example, water that has been desorbed into the regeneration fluid(s) at desorption zone 312 of desiccation device 304. In these embodiments, condenser 305 can condense water vapor from the regeneration fluid(s) into liquid water. Accordingly, in many embodiments, condenser 305 can cool the regeneration fluid(s) by extracting thermal energy from the regeneration fluid(s) in order to condense water vapor from the regeneration fluid(s) into liquid water. In some embodiments, condenser 305 can transfer thermal energy extracted from the regeneration fluid(s) to the process fluid upstream of desiccation device 304 and/or to the atmosphere around (e.g., adjacent to) water generating unit 301.
In many embodiments, waste-heat-receiving-heat exchanger 303 can provide thermal energy to the regeneration fluid(s) so that the regeneration fluid(s) are heated upon arriving at desiccant device 304. Exposing desiccant element 313 of desiccation device 304 to the heated regeneration fluid(s) at desorption zone 312 of desiccation device 304 can regenerate desiccant element 313 of desiccation device 304 by causing water to desorb from desiccant element 313 into the regeneration fluid(s), thereby permitting desiccant element 313 to absorb more water from the process fluid at adsorption zone 311.
In many embodiments, in order to provide thermal energy to the regeneration fluid(s), waste-heat-receiving-heat exchanger 303 can receive waste heat from waste-heat-generating-system 302, can receive the regeneration fluid(s), and can transfer thermal energy from the waste heat to the regeneration fluid(s). Accordingly, water generating unit 301 can use the waste heat generated by waste-heat-generating-system 302 to generate water when the heated regeneration fluid(s) are received at desiccation device 304.
Waste heat of waste-heat-generating-system 302 can refer to heat generated by waste-heat-generating-system 302 (when waste-heat-generating-system 302 operates) that is unused by waste-heat-generating-system 302 after the heat is generated by waste-heat-generating-system 302. For example, in many embodiments, the waste heat of waste-heat-generating-system 302 can result as a by-product of the operation of waste-heat-generating-system 302. In these or other embodiments, the waste heat of waste-heat generating system 302 can be heat that would be released to the atmosphere around (e.g., adjacent to) waste-heat-generating-system 302 if unused by water generating unit 301 to generate water. Accordingly, system 300 advantageously can make use of waste heat of waste-heat-generating-system 302 to generate water rather than have the waste heat be wasted or otherwise go unused.
In many embodiments, when water generating unit 301 comprises heater 308, heater 308 can provide thermal energy to the regeneration fluid(s) so that the regeneration fluid(s) are heated upon arriving at desiccant device 304. For example, in order to provide thermal energy to the regeneration fluid(s), heater 308 can generate native heat, can receive the regeneration fluid(s), and can transfer thermal energy from the native heat to the regeneration fluid(s). The term “native heat” refers to heat generated by heater 308, and is used herein to distinguish heat generated by heater 308 from waste heat generated by waste-heat-generating-system 302.
In some embodiments, water generating unit 301 can be configured to use waste heat of waste-heat-generating-system 302 to supplement and/or replace the native heat of heater 308 to generate water. In some embodiments, when water generating unit 301 is configured to use the waste heat of waste-heat-generating-system 302 to replace the native heat of heater 308 to generate water, heater 308 can be omitted. However, in many embodiments, as explained in greater detail below, water generating unit 301 can comprise heater 308, and heater 308 can be selectively activated or deactivated, as needed, depending on whether the waste heat of waste-heat-generating-system 302 is supplementing or replacing the native heat of heater 308. Further, in these or other embodiments, when water generating unit 301 comprises heater 308, heater 308 can be used to generate water when waste heat from waste-heat-generating-system 302 is unavailable or is insufficient for use to generate water.
In some embodiments, whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 to supplement or replace the native heat of heater 308 can depend on a waste heat temperature of the waste heat of waste-heat-generating-system 302 and/or a waste heat rate of flow of the waste heat of waste-heat-generating-system 302. For example, in many embodiments, water generating unit 301 can be configured to use the waste heat of waste-heat-generating-system 302 to replace the native heat of heater 308 when the waste heat temperature of the waste heat exceeds a maximum native heat temperature of the native heat generated by heater 308. In these or other embodiments, water generating unit 301 can be configured to use the waste heat of waste-heat-generating-system 302 to supplement the native heat of heater 308 when the waste heat rate of flow of the waste heat exceeds a maximum native heat rate of flow of the native heat generated by heater 308. In further embodiments, water generating unit 301 can be configured to use the waste heat of waste-heat-generating-system 302 to supplement or replace the native heat of heater 308 when the waste heat temperature exceeds a maximum native heat temperature of the native heat generated by heater 308 and when the waste heat rate of flow of the waste heat exceeds a maximum native heat rate of flow of the native heat generated by heater 308. Accordingly, in some embodiments, whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 to supplement or replace the native heat of heater 308 can depend on the type of system that waste-heat-generating-system 302 comprises, as explained in greater detail below.
Replacing the native heat of heater 308 with the waste heat of waste-heat-generating-system 302 can be advantageous when it is desirable to use energy that would otherwise be used by heater 308 to generate the native heat for other purposes and/or when energy to run heater 308 is unavailable, such as, for example, when heater 308 comprises a solar thermal heater and when sunlight is unavailable. Also, replacing the native heat of heater 308 with the waste heat of waste-heat-generating-system 302 can be advantageous to reduce wear and tear on heater 308. Meanwhile, supplementing the native heat of heater 308 with the waste heat of waste-heat-generating-system 302 can be advantageous to generate more water than may be possible with the native heat of heater 308 alone.
In many embodiments, water generating unit 301 can be configured to use the waste heat of waste-heat-generating-system 302 to replace the native heat of heater 308 when the waste heat temperature of the waste heat is greater than or equal to approximately 80 degrees Celsius, 100 degrees Celsius, 180 degrees Celsius, or 200 degrees Celsius. In these or other embodiments, water generating unit 301 can be configured to use the waste heat of waste-heat-generating-system 302 to supplement the native heat of heater 308 when the waste heat rate of flow of the waste heat is greater than or equal to approximately 1,000 watts, 1,200 watts, 3,000 watts, or 3,500 watts.
In many embodiments, waste-heat-generating-system 302 can comprise any suitable system configured to generate waste heat. Further, in some embodiments, such as, for example, when water generating unit 301 comprises heater 308, waste-heat-generating-system 302 can comprise a system configured to generate waste heat having a waste heat temperature exceeding a maximum native heat temperature of the native heat generated by heater 308 and/or a waste heat rate of flow exceeding a maximum native heat rate of flow of the native heat generated by heater 308.
In many embodiments, waste-heat-generating-system 302 can be a stand-alone system that can operate separately and/or independently from water generating unit 301. In these or other embodiments, waste-heat-generating-system 302 can be useful without being used with water generating unit 301.
In some embodiments, waste-heat-generating-system 302 can comprise a heating fire (e.g., a campfire, a gas heater and/or stove, etc.), a heating element, an electric generator, a fuel cell, a heat engine (e.g., an internal combustion engine), multiple computer servers (e.g., a server farm), or a refrigeration system (e.g., an air conditioner, a refrigerator, etc.). For example, in some embodiments, a gas heater and/or stove can comprise a butane gas heater and/or stove. In some embodiments, a heating fire can comprise a cooking fire, such as, for example, when a heating fire is being used to cook food. Further, a heating element can comprise a cooking element, such as, for example, when a heating element is being used to cook food. In some embodiments, waste-heat-generating-system 302 can be a system other than a system configured to generate water.
As indicated above, the type of system that waste-heat-generating-system 302 comprises can determine whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 to supplement or replace the native heat of heater 308. In some embodiments, when waste-heat-generating-system 302 comprises a heating fire and/or a cooking fire (e.g., a campfire), waste heat from waste-heat-generating-system 302 may supplement or replace native heat from heater 308, such as, for example, because waste heat from a heating fire and/or a cooking fire (e.g., a campfire) may have a waste heat temperature (e.g., approximately 500 degrees Celsius) and a waste heat rate of flow (e.g., approximately 500 watts-2000 watts) exceeding a maximum native heat temperature and a maximum native heat rate of flow of the native heat of heater 308. In these or other embodiments, when waste-heat-generating-system 302 comprises an electric generator, waste heat from waste-heat-generating-system 302 may replace native heat from heater 308, such as, for example, because waste heat from an electric generator may have a waste heat temperature (e.g., approximately 100 degrees Celsius) exceeding a maximum native heat temperature of the native heat of heater 308, but a waste heat rate of flow (e.g., approximately 800 watts) below a maximum native heat rate of flow of the native heat of heater 308. In these or other embodiments, when waste-heat-generating-system 302 comprises a refrigeration system, waste heat from waste-heat-generating-system 302 may supplement native heat from heater 308, such as, for example, because waste heat from a refrigeration system may have a waste heat rate of flow (e.g., approximately 300 watts-1500 watts) exceeding a maximum native heat rate of flow of the native heat of heater 308, but a waste heat temperature (e.g., approximately 60 degrees Celsius) below a maximum native heat temperature of the native heat of heater 308.
Further, in some embodiments, the type of system that waste-heat-generating-system 302 comprises can determine a size and weight of water generating unit 301. For example, as a waste heat temperature and/or a waste heat rate of flow of the waste heat generated by waste-heat-generating-system 302 increases, a size of water generating unit 301 can be reduced, thereby increasing a portability of water generating unit 301. In particular, as a waste heat temperature and/or a waste heat rate of flow of the waste heat generated by waste-heat-generating-system 302 increases, water generating unit 302 can generate more water for a constant volume of the process fluid and/or a constant surface area of desiccant element 313 up to the physical limits of the process fluid and/or desiccant element 313. In many embodiments, the type of system implemented for waste-heat-generating-system 302 can be selected such that water generating unit 301 can comprise a weight less than or equal to approximately 45 kilograms (100 pounds) or approximately 36 kilograms (80 pounds).
In many embodiments, waste-heat-receiving-heat exchanger 303 can comprise any suitable device configured to receive waste heat from waste-heat-generating-system 302, receive the regeneration fluid(s), and transfer thermal energy from the waste heat to the regeneration fluid(s). For example, in some embodiments, waste-heat-receiving-heat exchanger 303 can comprise a solid wall heat exchanger or coil heat exchanger. The type of heat exchanger implemented for waste-heat-receiving-heat exchanger 303 can depend on the type of system of waste-heat-generating-system 302, on whether the waste heat of waste-heat-generating-system 302 is supplementing or replacing native heat of heater 308, and/or a desired size and/or weight of water generating system 301. For example, in some embodiments, when waste-heat-generating-system 302 comprises a heat engine, waste-heat-receiving-heat exchanger 303 can be mounted to an exhaust device of the heat engine. In other embodiments, when waste-heat-generating-system 302 comprises a campfire, waste-heat-receiving-heat exchanger 303 can be placed in or proximal to the campfire.
In many embodiments, heater 308 can comprise any suitable device configured to generate native heat, receive the regeneration fluid(s), and transfer thermal energy from the native heat to the regeneration fluid(s). For example, in many embodiments, heater 308 can comprise a solar thermal heater. In these embodiments, the solar thermal heater can convert solar insolation to the thermal energy provided to the regeneration fluid(s). In some embodiments, heater 308 can be configured to generate native heat comprising a maximum native heat temperature of approximately 80 degrees Celsius or approximately 100 degrees Celsius and/or a maximum native heat rate of flow of approximately 1,000 watts or approximately 1,200 watts.
Further, in these embodiments, heater 308 can be part of a solar panel, which can generate electricity to electrically power part or all of water generating unit 301. In these or other embodiments, part or all of water generating unit 301 can be electrically powered by any other suitable source of electricity (e.g., a battery, a fuel cell, an electric grid, etc.).
As noted above, in some embodiments, when water generating unit 301 comprises heater 308, heater 308 can be coupled in parallel with waste-heat-receiving-heat exchanger 303, such as, for example, between condenser 305 and desiccation device 304. Arranging heater 308 in parallel with waste-heat-receiving-heat exchanger 303 can be advantageous in situations where only one of waste-heat-receiving-heat exchanger 303 or heater 308 is being used to transfer thermal energy to the regeneration fluid(s). For example, using valves, portions of the conduits routing the regeneration fluid(s) to waste-heat-receiving-heat exchanger 303 or heater 308 can be bypassed when one of waste-heat-receiving-heat exchanger 303 or heater 308 is not in use to reduce losses in thermal energy from the regeneration fluid(s).
In many embodiments, reservoir 315 can store water extracted from the regeneration fluid(s) by condenser 305. Accordingly, reservoir 315 can comprise any suitable receptacle or container configured to store water. Further, reservoir 315 can be coupled to condenser 305 to receive the water extracted from the regeneration fluid(s) by condenser 305.
In many embodiments, filter 316 can be operable to filter water output by condenser 305, such as, for example, to remove one or more materials (e.g., one or more materials toxic to humans) from the water. Accordingly, filter 316 can be coupled to an output of condenser 305, such as, for example, between condenser 305 and reservoir 315. Filter 316 can comprise any suitable device configured to filter water. For example, filter 316 can comprise a carbon filter or a stainless steel frit.
In many embodiments, filter 317 can be operable to filter water output by reservoir 315, such as, for example, to remove one or more materials (e.g., one or more materials toxic to humans) from the water. Accordingly, filter 317 can be coupled to an output of reservoir 315. Filter 317 can comprise any suitable device configured to filter water. For example, filter 317 can comprise a carbon filter or a stainless steel frit. In some embodiments, filter 317 can be omitted, such as, for example, when reservoir 315 is omitted.
In many embodiments, condenser heat exchanger 309 can be operable to transfer thermal energy from the regeneration fluid(s) upstream of condenser 305 to the regeneration fluid(s) downstream of condenser 305. For example, removing thermal energy from the regeneration fluid(s) upstream of condenser 305 can help prime or pre-cool the water vapor in the regeneration fluid(s) to be condensed into liquid water at condenser 305 by reducing the regeneration fluid(s) to nearer to a temperature at which the water vapor will condense into liquid water. Meanwhile, the thermal energy extracted from the regeneration fluid(s) by condenser heat exchanger 309 can be transferred to the regeneration fluid(s) downstream of condenser 305 so that the thermal energy can heat the regeneration fluid(s) upstream of desiccation device 304. As a result, implementing condenser heat exchanger 309 can make system 300 more efficient by making use of thermal energy in the regeneration fluid(s) that would otherwise be lost to condenser 305 to heat the regeneration fluid(s) heading to desiccation device 304.
In some embodiments, water generating unit control system 310 can be operable to control one or more parts of water generating unit 301. For example, in many embodiments, water generating unit control system 310 can control operation of blower 306, circulator 307 and/or actuator 314. Further, in some embodiments, water generating unit control system 310 can control operation of condenser 305, such as, for example, when condenser 305 is implemented as an active device.
For example, in some embodiments, water generating unit control system 310 can control (e.g., increase or decrease) a speed at which blower 306 moves (e.g., pumps) the process fluid. Further, in these or other embodiments, water generating unit control system 310 can control (e.g., increase or decrease) a speed at which circulator 307 moves (e.g., pumps) the regeneration fluid(s). Further still, in these or other embodiments, water generating unit control system 310 can control (e.g., increase or decrease) a speed at which actuator 314 moves (e.g., rotates) desiccant element 313.
In some embodiments, water generating unit control system 310 can employ a control algorithm to control blower 306, circulator 307 and/or actuator 314, such as, for example, in a manner that maximizes the water generated by water generating unit 301. For example, the control algorithm can determine (e.g., solve) optimal control conditions for blower 306, circulator 307 and/or actuator 314 as a function of an ambient air temperature at water generating unit 301, an ambient air relative humidity at water generating unit 301, the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308. Accordingly, water generating unit control system 310 can communicate with one or more sensors of water generating unit 301 (e.g., one or more temperature sensors, one or more humidity sensors, one or more heat rate of flow sensors, etc.) configured to measure the ambient air temperature at water generating unit 301, the ambient air relative humidity at water generating unit 301, the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308. Further, in these or other embodiments, the control algorithm can determine (e.g., solve) optimal control conditions for blower 306, circulator 307 and/or actuator 314 relative to each other.
For example, in some embodiments, water generating unit control system 310 can decrease the speed of actuator 314 as the ambient air temperature at water generating unit 301 and/or the ambient air relative humidity at water generating unit 301 increases, and/or the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308 decreases. In these or other embodiments, water generating unit control system 310 can increase the speed of actuator 314 as the ambient air temperature at water generating unit 301 and/or the ambient air relative humidity at water generating unit 301 decreases, and/or the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308 increases.
In some embodiments, water generating unit control system 310 can increase the speed of blower 306 and/or circulator 307 as the ambient air temperature at water generating unit 301 and/or the ambient air relative humidity at water generating unit 301 increases, and/or the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308 decreases. In these or other embodiments, water generating unit control system 310 can decrease the speed of blower 306 and/or circulator 307 as the ambient air temperature at water generating unit 301 and/or the ambient air relative humidity at water generating unit 301 decreases, and/or the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308 increases.
In some embodiments, water generating unit control system 310 can control whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 and/or the native heat of heater 308 to transfer thermal energy to the regeneration fluid(s). For example, in some embodiments, water generating unit control system 310 can control whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 and/or the native heat of heater 308 to transfer thermal energy to the regeneration fluid(s) by controlling a path of the regeneration fluid(s) with valves of the conduits that convey the regeneration fluid(s). In these or other embodiments, water generating unit control system 310 can control whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 and/or the native heat of heater 308 to transfer thermal energy to the regeneration fluid(s) by selectively activating and deactivating heater 308.
In some embodiments, water generating unit control system 310 can employ a control algorithm to control whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 and/or the native heat of heater 308 to transfer thermal energy to the regeneration fluid(s), such as, for example, in a manner that maximizes the water generated by water generating unit 301 and/or minimizes electricity used by water generating unit 301. For example, the control algorithm can determine whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 and/or the native heat of heater 308 to transfer thermal energy to the regeneration fluid(s) as a function of an ambient air temperature at water generating unit 301, an ambient air relative humidity at water generating unit 301, the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308. Accordingly, water generating unit control system 310 can communicate with one or more sensors of water generating unit 301 (e.g., one or more temperature sensors, one or more humidity sensors, one or more heat rate of flow sensors, etc.) configured to measure the ambient air temperature at water generating unit 301, the ambient air relative humidity at water generating unit 301, the waste heat temperature of the waste heat of waste-heat-generating-system 302, the waste heat rate of flow of the waste heat of waste-heat-generating-system 302, the native heat temperature of the native heat of heater 308, and/or the native heat rate of flow of the native heat of heater 308. In many embodiments, the control algorithm for determining whether water generating unit 301 uses the waste heat of waste-heat-generating-system 302 and/or the native heat of heater 308 to transfer thermal energy to the regeneration fluid(s) can be part of the control algorithm that controls blower 306, circulator 307 and/or actuator 314, and vice versa.
In some embodiments, water generating unit control system 310 can communicate with one or more sensors of water generating unit 301 (e.g., one or more particle sensors, one or more gas sensors, etc.) configured to detect a presence and/or a quantity of one or more materials toxic to humans, pets, and/or other animals in the process fluid. Further, water generating unit control system 310 can be configured to prevent water generating unit 301 from generating water when these material(s) are detected and/or when a predetermined quantity of these material(s) are present in the process fluid. For example, in some embodiments, one or more gases (e.g., carbon monoxide) emitted by waste-heat-generating-system 302 may mix with the process fluid, resulting in water generating unit 301 generating toxic water. Accordingly, water generating unit control system 310 can disable water generating unit 301 upon detecting such conditions.
In many embodiments, water generating unit control system 310 can comprise any suitable device configured to control operation of water generating unit 301. Accordingly, water generating unit control system 310 can be electrically coupled to condenser 305, blower 306, circulator 307, heater 308, actuator 314, and/or one or more sensors (e.g., one or more temperature sensors, one or more humidity sensors, one or more heat rate of flow sensors, one or more particle sensors, one or more gas sensors, etc.) of water generating unit 301. In many embodiments, water generating unit control system 310 can be similar or identical to computer system 100 (
In some embodiments, water generating unit control system 310 can be located remotely from where water generating unit 301 generates water when controlling operation of water generating unit 301. However, in other embodiments, water generating unit control system 310 can be located near to or at a location where water generating unit 310 generates water when controlling operation of water generating unit 301.
Although system 300 is described with respect to one waste-heat-generating-system (i.e., waste-heat-generating-system 302), in some embodiments, system 300 can be modified and implemented to use waste heat from one or more additional waste-heat-generating-systems, simultaneously and/or at different times. In these embodiments, the waste heat of the multiple waste-heat-generating-systems can be received by one waste-heat-receiving-heat exchanger (e.g., waste-heat-receiving-heat exchanger 303) or multiple waste-heat receiving heat exchangers similar or identical to waste-heat-receiving-heat exchanger 303. Further, the additional waste-heat-generating-systems can be similar or identical to waste-heat-generating-system 302.
Further, although system 300 is described with respect to one desiccation device (i.e., desiccation device 304), in some embodiments, system 300 can be modified and implemented with one or more additional desiccation devices, which can be similar or identical to desiccation device 304. In these embodiments, desiccation device 304 and the additional device(s) can be implemented in series and/or in parallel with each other, as desired.
