The present disclosure is directed to systems, apparatuses, and methods for determining which zone(s) are to receive excess air flow, and more particularly to determining the zones in a manner that is efficient.
Modern heating, ventilation, and air conditioning (HVAC) systems can provide conditioned air to a large group of individually controllable zones. Typically, the HVAC system is designed to be capable to meet the needs of the entire group. Hence, it is a common situation that one of the HVAC devices, such as an air handler or the like, when activated at a minimum setting, will provide more tempered air than is necessary to serve any one zone. It is also a common situation for a single zone from among the group to meet conditions such as a set point criterion that will cause the HVAC device to activate while the remainder of the zones do not meet any such conditions, and therefore do not need and/or do not trigger the HVAC device. As a result, the HVAC device is activated at a minimum setting (e.g., 750 cubic feet per minute (CFM)), that still provides more airflow than is needed to meet the demands of the signaling zone (e.g., 100 CFM). This remainder (e.g., 750 CFM−100 CFM=650 CFM), is referred to herein as excess air flow.
The following presents a summary to provide a basic understanding of one or more embodiments of the disclosure. This summary is not intended to identify key or critical elements or delineate any scope of the particular embodiments or any scope of the claims. Its sole purpose is to present concepts in a simplified form as a prelude to the more detailed description that is presented later.
According to an embodiment of the present disclosure, a device can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The computer executable instructions can comprise determining that a heating, ventilation, and air conditioning (HVAC) device, configured to provide a defined volume of air, is indicated to activate in response to an activation condition being satisfied with respect to a first zone of a group of zones. The computer executable instructions can comprise determining an excess volume of air representative of the defined volume of air provided by the HVAC device less a first zone volume that is delivered to the first zone. The computer executable instructions can comprise, performing an excess routing procedure that identifies a second zone of the group of zones to which to route at least a portion of the excess volume.
According to an embodiment of this disclosure, the performing the excess routing procedure can comprise determining that the second zone, from among the group of zones, is most likely to trigger a subsequent activation condition for the HVAC device.
According to an embodiment of this disclosure, the performing the excess routing procedure can comprise determining respective differences between respective measured quantities of respective zones of the group and corresponding unoccupied set points of the respective zones. Thereafter, the second zone can be identified in response to determining that the second zone has a smallest difference from among the respective differences.
According to an embodiment of this disclosure, the performing the excess routing procedure can comprise determining respective differences between respective measured quantities of respective zones of the group and corresponding occupied set points of the respective zones. Thereafter, the second zone can be identified in response to determining that the second zone has a largest difference from among the respective differences.
According to an embodiment of this disclosure, the performing the excess routing procedure can comprise determining respective rates of change of respective measured quantities of respective zones of the group. Thereafter, the second zone can be identified based on respective states of the respective zones and the respective rates of change.
According to an embodiment of this disclosure, the performing the excess routing procedure can comprise identifying the second zone based on a determination that the second zone is most likely, from among the group of zones, to be a next zone to be occupied.
In some embodiments, elements described in connection with the systems above can be embodied in different forms such as a computer-implemented method, a computer-readable medium, or another form.
While this specification discusses and refers to an excess air flow, it is understood that the disclosed techniques can be applicable to any fluid flow in addition to air flow. As noted previously, a common situation arises where an HVAC device (e.g., a fan, blower, air handler, etc.) is activated in response to activation conditions being met by one or more zones served by the HVAC device. For example, if a given state of a zone satisfies an activation condition (e.g., a set point), such can trigger a signal to activate the HVAC device. Because the HVAC device can be sized to serve many zones, but only one zone or a few zones may be in a state to meet activation conditions, activating the HVAC device can be inefficient.
For instance, consider the case where the HVAC device provides, at a minimum setting, 750 CFM, whereas the zone that triggered the activation is supplied only 100 CFM. It is appreciated that if one or more zones collectively call for more than is provided by the minimum setting, say 800 CFM, the HVAC device might be activated at an intermediate setting that may provide, for example, 1000 CFM, causing an excess of 200 CFM. In either case, it is appreciated that excess air flow will exist, and the disclosed techniques are equally applicable to either scenario.
Returning to the first example, where the excess air flow is 650 CFM (e.g., 750 CFM provided by HVAC device less 100 CFM allocated to the activating zone), it can be especially inefficient or wasteful if that excess air flow is not put to work in some way in the system. Known approaches to allocating and/or routing the excess air flow are not satisfactory. For example, other systems that at least attempt to make use of the excess air flow tend take one of the two following approaches: (1) distribute the excess air flow among all zones or some predetermined subset of the zones; or (2) distribute the excess air flow to a predetermined specific class of zones. An example is common areas, such as bathrooms, conference rooms, or the like. Both approaches tend to be wasteful.
The disclosed subject matter introduces better intelligence in determining where to route excess air flow, which can be more efficient in terms of energy consumption. Furthermore, the disclosed techniques can reduce the duty cycle of HVAC equipment, which can extend the life of certain HVAC equipment. As one illustrative example, the disclosed subject matter can intelligently determine to route excess air flow to zones that are determined to be more likely to trigger a subsequent activation condition. Such can extend the time between the subsequent activation condition being triggered and/or reduce the load when the subsequent activation condition is triggered.
The disclosed subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed subject matter. It may be evident, however, that the disclosed subject matter may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the disclosed subject matter.
Referring now to the drawings, with initial reference to
System 100 can further comprise a heating, ventilation, and air conditioning (HVAC) device 102, which can be for example, a fan, blower, air handler, and so forth. HVAC device 102 can be configured to provide a defined volume of air 104 (also referred to herein as defined volume 104 and airflow 104) upon activation. Defined volume 104 can be representative of a volume of air that is provided by HVAC device 102 based on a setting, typically, but not necessarily, a minimum setting for the HVAC device 102.
Defined volume 104 can be provided to some portion of group of zones 106, illustrated here as first zone 1061 to Nth zone 106N, where N can be any whole number, but will typically be greater than three. In some embodiments, individual members of group of zones 106 can be individually controlled. For example, distinct set points can be input for any member of the group of zones 106. When a state of one of the group of zones 106 (e.g., first zone 1061) satisfies a set point (or other activation condition 110), an appropriate device can transmit activation request 108 to HVAC device 102, indicating that HVAC device 102 is to be activated.
Device 101 can determine that HVAC device 102 is indicated to be activated (e.g., receiving and potentially forwarding activation request 108). In response, device 101 can perform determination 112. Determination 112 can comprise determining an excess volume of air. The excess volume of air can represent defined volume 104 (e.g., provided by HVAC device 102 at a minimum or other setting) less a first zone volume that is to be delivered to the zone triggering activation request 108 (e.g., first zone 1061).
Once the excess volume is determined, device 101 can perform excess routing procedure 114. Excess routing procedure 114 can identify a second zone 1062 of the group of zones 106 to which to route at least a portion of the excess volume. Excess routing procedure can include determination 116. Determination 116 can comprise determining that second zone 1062, from among group of zones 106, is most likely to trigger a subsequent activation condition for HVAC device 102.
In some embodiments, if multiple zones are determined to be equally likely to trigger the subsequent activation condition, second zone 1062 can be selected due to the amount of CFM required. For example, of the two candidates, the zone that has a CFM requirement that is closest to using up the excess routing procedure without going under can be selected. In some embodiments, excess routing procedure 114 can be performed iteratively to identify additional zone(s) of group of zones 106 to which to route the excess volume until no excess volume remains.
While still referring to
It is appreciated that a given zone 106 can have multiple set points, for example, an occupied set point and an unoccupied set point. The unoccupied set point is typically not as comfortable to occupants as the occupied set point, but rather is selected to reduce the demands on the HVAC system. For instance, during the day when an associated building is occupied, group of zones 106 can operate according to comfort settings associated with occupied set points. At night, when few or no people are in the building, group of zones 106 can operate according to the unoccupied set points in which comfort settings and other thresholds can be greatly relaxed. If however, someone enters one of the zones 106, such can satisfy activation condition 110, either by satisfying occupancy set point 202 or satisfying temperature set point 204, humidity set point 206 or another suitable set point as the associated set point reverts from the unoccupied value to the occupied value.
Regardless, once activation condition 110 is satisfied, a signal (e.g., activation request 108) can be sent to trigger activation of HVAC device 102 and device 101 can perform excess routing procedure 114 to determine where to route the excess flow. As mentioned, excess routing procedure 114 can comprise determination 116 that identifies a zone 106 that is most likely to trigger a subsequent activation condition
Therefore, supposing first zone 1061 triggers activation condition 110 because a temperature of first zone 1061 meets an unoccupied set point, device 101 can examine how close other zones 106 are to meeting their own respective unoccupied set points. The zone 106, e.g., second zone 1062, with the smallest difference from an associated unoccupied set point can be inferred to be the one most likely to trigger a subsequent activation condition, which is illustrated at reference numeral 212. Hence, second zone 1062 that is nearest to the conditions that will trigger a subsequent activation condition can be selected to receive all or a portion of the excess air flow. In other words, device 101 can determine respective differences between respective measured quantities (e.g., occupancy, temperature, humidity, etc.) of respective zones 106 and corresponding unoccupied set points of the respective zones 106. Next, device 101 can identify second zone 1062 in response to determining that second zone 1062 has the smallest difference from among the respective differences. As a result, the physical state of second zone 1062 will move away from the unoccupied set point, and thus be less likely to trigger a subsequent activation condition.
As another example illustrated by reference numeral 214, determination 116 can identify second zone 1062 as most likely to trigger a subsequent activation condition based on having a largest difference from an occupied set point. It is understood that the physical conditions of the group of zones 106 will typically be in a range between the occupied set point (that is no longer enforced when unoccupied) and the unoccupied set point (that, if met, will trigger activation of HVAC device 102). Depending on settings, some zones 106 can be much farther away from the occupied set point than others, without nearing the unoccupied set point that would trigger HVAC device 102 activation. The inventors have observed that in the case of a very large difference from an occupied set point, when the second zone 1062 does become occupied, it can take a long time to correct the temperature or other physical conditions of second zone 1062, which can also be inefficient or less desirable.
In other words, device 101 can determine respective differences between respective measured quantities (e.g., occupancy, temperature, humidity, etc.) of respective zones 106 and corresponding occupied set points of the respective zones 106. Next, device 101 can identify second zone 1062 in response to determining that second zone 1062 has the largest difference from among the respective differences. As a result, the physical state of second zone 1062 can be brought to the occupied set point thresholds more quickly.
In another example illustrated by reference numeral 216, determination 116 can identify second zone 1062 as most likely to trigger a subsequent activation condition based on a rate of change of a physical quantity. In other words, device 101 can determine respective rates of change of respective measured quantities of respective zones 106. Next, device 101 can identify second zone 1062 in response to determining that second zone 1062 has the highest rate of change either away from an occupied set point or toward an unoccupied set point. It is understood that having a greater rate of change can be another indicator in determining zones 106 that are most likely to trigger a subsequent activation condition.
Reference numeral 218 illustrates yet another mechanism for determination 116. For example, based on a history, a schedule, or other data, second zone 1062 can be identified as most likely to trigger a subsequent activation condition based on a determination that second zone 1062 will be occupied next. As explained, when a zone 106 becomes occupied, set points can revert from the unoccupied setting to the occupied setting, which will typically trigger activation request 108. By providing second zone 1062 with the excess flow in advance, the effects of switching to occupied mode can be reduced sharply.
With reference now to
System 300 can include device 101 that can perform determination 116 as well as other determinations detailed herein, and HVAC device 102 that, when activated, can provide the defined volume 104 of air, illustrated here as airflow 104, which, in this example is 750 CFM. HVAC device 102 serves ten different zones, each of which can be individually controlled and thus maintain individual set points.
Device 101 can include or be communicatively coupled to data store 302 that can store various data sets 304 that can be employed to determine excess volume 112 or perform excess routing procedure 114. For example, data set 304 can include information about various settings for HVAC device and the defined volume 104. Data set 304 can further include various zone state data 306 indicative of a states (e.g., physical conditions) of the various zones, corresponding set point, both occupied and unoccupied, and so forth. The present example is directed to a non-limiting cooling example.
As depicted, zone 1 has a current temperature of 80° that is above the unoccupied cooling set point of 78°, which causes activation request 108. No other zones meet conditions that would trigger HVAC device 102 activation. Device 101 can determine that HVAC device 102 is being activated and further determine the excess volume. In this case, the defined volume 104 is 750 CFM (e.g., a minimum setting for HVAC device 102) while the airflow demand of zone 1 is 100 CFM. Thus, the excess volume is 750-100=650 CFM, which device 101 can intelligently allocate based on performing the excess routing procedure 114.
Excess routing procedure 114, in this example, can identify a current deviation or difference from the corresponding unoccupied set point. In order of smallest to largest zone 4 is only 1° away from the unoccupied set point and therefore can be considered to be most likely to trigger a subsequent activation condition that will activate HVAC device 102. Next is zone 3, which is 2° away from the respective unoccupied set point, followed by zone 7 (3° away), zones 1 and 10 (4° away), zone 6 (5° away) zones 5 and 9 (6° away), and zone 8 (8° away).
Once sorted on closest to set point, the zones can be chosen to meet defined volume 104. In this case, the excess routing procedure 114 selects zones 4, 3, 7, and 2. Including the 100 CFM demanded by zone 1, which triggered HVAC device 102, the total airflow demand of the selected zones is 100+300+150+125+200=875 CFM. It is noted that both zone 2 and zone 10 are 4° from their respective set points, however, the excess routing procedure 114 selected zone 2 instead of zone 10 because zone 2 provides the closest airflow match to the defined volume 104 provided by HVAC device 102 at the current setting. In other words, when multiple zones will meet the smallest different criteria, excess routing procedure 114 can first select the zones closest to their unoccupied set point. If multiple spaces have the same deviation from that set point (e.g., zones 2 and 10) the application can select the zone resulting in the closest total to defined volume 104 without going under. Had zone 10 been selected instead of zone 2, the total airflow demand would be 100+300+150+125+320=995 CFM, which is farther away from the defined volume of 750 CFM and thus less preferred in this embodiment. It is appreciated that, in other embodiments, the 995 CFM might be preferred and in those cases, zone 10 can be selected instead of zone 2.

Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
As used in this application, the terms “component,” “system,” “platform,” “interface,” and the like, can refer to and/or can include a computer-related entity or an entity related to an operational machine with one or more specific functionalities. The entities disclosed herein can be either hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component. One or more components can reside within a process and/or thread of execution and a component can be localized on one computer and/or distributed between two or more computers. In another example, respective components can execute from various computer readable media having various data structures stored thereon. The components can communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, which is operated by a software or firmware application executed by a processor. In such a case, the processor can be internal or external to the apparatus and can execute at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, wherein the electronic components can include a processor or other means to execute software or firmware that confers at least in part the functionality of the electronic components. In an aspect, a component can emulate an electronic component via a virtual machine, e.g., within a cloud computing system.
In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. Moreover, articles “a” and “an” as used in the subject specification and annexed drawings should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. As used herein, the terms “example” and/or “exemplary” are utilized to mean serving as an example, instance, or illustration and are intended to be non-limiting. For the avoidance of doubt, the subject matter disclosed herein is not limited by such examples. In addition, any aspect or design described herein as an “example” and/or “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs, nor is it meant to preclude equivalent exemplary structures and techniques known to those of ordinary skill in the art.
As it is employed in the subject specification, the term “processor” can refer to substantially any computing processing unit or device comprising, but not limited to, single-core processors; single-processors with software multithread execution capability; multi-core processors; multi-core processors with software multithread execution capability; multi-core processors with hardware multithread technology; parallel platforms; and parallel platforms with distributed shared memory. Additionally, a processor can refer to an integrated circuit, an application specific integrated circuit (ASIC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic controller (PLC), a complex programmable logic device (CPLD), a discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein.
Further, processors can exploit nano-scale architectures such as, but not limited to, molecular and quantum-dot based transistors, switches and gates, in order to optimize space usage or enhance performance of user equipment. A processor can also be implemented as a combination of computing processing units. In this disclosure, terms such as “store,” “storage,” “data store,” data storage,” “database,” and substantially any other information storage component relevant to operation and functionality of a component are utilized to refer to “memory components,” entities embodied in a “memory,” or components comprising a memory. It is to be appreciated that memory and/or memory components described herein can be either volatile memory or nonvolatile memory or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), flash memory, or nonvolatile random-access memory (RAM) (e.g., ferroelectric RAM (FeRAM). Volatile memory can include RAM, which can act as external cache memory, for example. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), direct Rambus RAM (DRRAM), direct Rambus dynamic RAM (DRDRAM), and Rambus dynamic RAM (RDRAM). Additionally, the disclosed memory components of systems or computer-implemented methods herein are intended to include, without being limited to including, these and any other suitable types of memory.
What has been described above include mere examples of systems and computer-implemented methods. It is, of course, not possible to describe every conceivable combination of components or computer-implemented methods for purposes of describing this disclosure, but one of ordinary skill in the art can recognize that many further combinations and permutations of this disclosure are possible. Furthermore, to the extent that the terms “includes,” “has,” “possesses,” and the like are used in the detailed description, claims, appendices and drawings such terms are intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim. The descriptions of the various embodiments have been presented for purposes of illustration but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
