Abstract

Computer-implemented methods and related systems enable measurement of efficiency of Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) systems. The method includes receiving data regarding an HVACR system at a processor. The data is received from one or more probes installed on the HVACR system. The method also includes processing the data to determine an efficiency of the HVACR system and displaying the measured efficiency on a network device. Accordingly, technicians, engineers and property managers can monitor HVACR systems and can use the measured data to maintain or repair HVACR systems, to understand their effectiveness and cost-efficiencies and to design HVACR systems for building spaces.

Description

BACKGROUND

[0001] According to some estimates, approximately half of the energy consumed in an average residential household comes from heating, ventilation, air conditioning, and refrigeration (HVACR) systems. The average household HVACR lifespan is 12 to 15 years, when properly installed and maintained. A typical residential air conditioning system that is seldom maintained can lose approximately 26% of its efficiency after 10 years and approximately 37% of its efficiency after 15 years. A residential air conditioning system that is maintained properly still loses approximately 10% of its efficiency after 10 years and approximately 14% of its efficiency after 15 years.

[0002] To put these figures in perspective, if an air conditioning system is 15 years old and hasn't been maintained properly, approximately 18% of a power bill that includes this air conditioning system is probably due to an inefficient of the system. This 18% does not even consider other factors that can decrease the efficiency of the air conditioning system, such as an inadequate home insulation factor caused by air imbalance, poor insulation, improperly set fan speeds and air infiltration.

[0003] Accurately measuring the efficiency of an HVACR system is critical to ensure that the HVACR system is running properly, and money is not being wasted. However, current methods for measuring the efficiency of HVACR systems can be inaccurate and lead to extreme misdiagnosis. For example, measuring refrigerant properties in an air conditioning system may be an unreliable way to determine efficiency of an air conditioning system because other factors, such as refrigerant impurities and or degradation, can change the heat transfer properties dramatically. Thus, improvements can be made to improve the accuracy of efficiency measurements of HVACR systems.

[0004] The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one example technology area where some embodiments described herein may be practiced.

DETAILED DESCRIPTION

[0015] Current methods for measuring the efficiency of HVACR systems can be inaccurate and lead to extreme misdiagnosis. Accurately measuring the efficiency of an HVACR system can be critical to a variety of different people and entities. For example, with accurate efficiency measurements: (a) power companies can add more people to the same grid; (b) residential consumers and complexes, and commercial businesses can save money on their utility bills and extend the life of their system; (c) industrial entities can react fast to problems, lower their overhead of maintenance personnel, extend the life of their equipment and lower their utility expenses; and (d) HVACR technicians can increase their value by quickly identifying problems.

[0016] Some embodiments disclosed herein may include air and fluid probes that can be used to accurately measure the efficiency of HVACR systems. These probes can have a variety of uses in residential settings. For example, in residential settings, probes can:

[0017] provide a notification when an HVACR system is not running efficiently and/or when air filters need to be replaced;

[0018] provide efficiency updates on an HVACR system in real-time;

[0019] give real-time system efficiency updates;

[0020] monitor how residents are using an HVACR system;

[0021] extend the life of the HVACR system; (f) provide information in real-time on how much the inefficiency of an HVACR system is costing in its current state and a forecast of the system's future inefficiency so that the consumer can prioritize financial decisions relating to the HVACR system;

[0022] help to identify problems with an HVACR system more quickly and more accurately; and

[0023] pull historic and real-time weather data to ensure accurate space r-value readings.

[0024] In addition to uses in residential settings, these probes have a variety of uses in commercial settings. To begin, these probes can be installed on many different commercial systems. For example, these probes may be installed on split systems, package units, chill water systems, geothermal systems, water source heat pumps, walk-in coolers, and walk-in freezers to name a few. In addition, probes used in a commercial setting can

[0025] save money on electric bills and reduce operating expenses;

[0026] integrate data from multiple probes that may be viewed together on a single easy to navigate platform;

[0027] provide a notification when an HVACR system is not running efficiently and/or when air filters need to be replaced;

[0028] detect and measure volatile organic compounds (VOCs), carbon dioxide, and other gasses (air probes);

[0029] provide real-time system efficiency updates;

[0030] analyze evaporator and condenser barrels in real-time to identify when scaling, refrigerant charge or water flow are becoming an issue;

[0031] analyze cooling towers in real-time to see when scaling, fan speed, water flow or humidity are an issue; and

[0032] consider historic and real-time weather data to make sure HVACR systems are running at maximum efficiency in any environment.

[0033] Turning to the figures, FIG. 1 illustrates an example system 100 configured for measuring the efficiency of an HVACR system. The system 100 may include a network 102, probes 104, an HVACR system 105, a webserver 106, a user device 108, and a mobile application marketplace server 110.

[0034] In some embodiments, the network 102 may be configured to communicatively couple probes 104, webserver 106, user device 108, and mobile application marketplace server 110 to one another and to other network devices using one or more network protocols, such as the network protocols available in connection with the World Wide Web. In some embodiments, the network 102 may be any wired or wireless network, or combination of multiple networks, configured to send and receive communications (e.g., via data packets) between systems and devices. In some embodiments, the network 102 may include a Personal Area Network (PAN), a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), a Storage Area Network (SAN), a cellular network, the Internet, or some combination thereof.

[0035] HVACR system 105 may include any heating, ventilation, air-conditioning, and/or refrigeration system. HVACR system 105 may include one or more conduits, channels, ducts, tubes, and pipes through which gasses or liquids may flow. HVACR system 105 may include one or more evaporator coils, evaporator barrels, condenser barrels, cooling towers, and/or boilers. HVACR system 105 may be configured for a residential use and/or commercial use.

[0036] In some embodiments, probes 104 may be devices for measuring and transmitting data from within HVACR system 105. Probes 104 may include air probes 104a and fluid probes 104b. Air probes 104a may be configured to measure and transmit data relating to a gas within HVACR system 105. For example, air probes 104a may include one or more sensors configured to measure a temperature, relative humidity, barometric pressure, and/or air flow rate of a gas within HVACR system 105. Fluid probes 104b may be configured to measure and transmit data relating to a liquid within HVACR system 105. For example, fluid probes 104b may include one or more sensors configured to measure a temperature, density, and/or flow rate of a liquid within HVACR system 105.

[0037] Probes 104 may transmit any measured data through network 102 to any network device connected to network 102, including webserver 106 and user device 108. In addition, probes 104 may transmit measured data directly to user device 108. For example, probes 104 may transmit data to user device 108 through a wired connection or a wireless connection, such as Bluetooth.

[0038] In some embodiments, webserver 106 may be any computer system capable of communicating over the network 102 with probes 104, user device 108, and/or mobile application marketplace server 110. Webserver 106 may make one or more mobile and/or web applications available to user device 108, including probe app 112. Webserver 106 may also host one or more websites, such as web portals that include web pages, addressable at a particular web domain. Webserver 106 may further include a processor 114.

[0039] In some embodiments, probe app 112 may be a mobile app that is available for download through a server, such as mobile application marketplace server 110. Mobile application marketplace server 110 may include, for example, the APP STORE provide by Apple Computer and the ANDROID application website. Probe app 112 may alternatively be a web application that is hosted by webserver 106. In addition, probe app 112 may be a desktop app, which is downloaded and installed on a desktop computer.

[0040] In some embodiments, user device 108 is a mobile communication device such as a mobile phone or a tablet computer. In alternative embodiments, user device 108 may be a laptop computer or a desktop computer. In embodiments where user device 108 is a mobile device, probe app 112 may be a mobile app downloaded from mobile application marketplace server 110 such as the APP STORE provide by Apple Computer or the ANDROID application website. In embodiments where user device 108 is a laptop or desktop computer, probe app 112 may be provided through a web application that is hosted by webserver 106.

[0041] Modifications, additions, or omissions may be made to the system 100 without departing from the scope of the present disclosure. For example, in some embodiments, system 100 may include additional components similar to the components illustrated in FIG. 1 that each may be configured similarly to the components illustrated in FIG. 1.

[0042] Probe app 112 may be configured to receive data that is measured by probes 104 and, using this data alone or together with additional data, calculate any number of different performance levels of an HVACR system, such as enthalpy. For example, probes 104 may measure the return and supply temperatures and relative humidity levels across an evaporator coil. Using these values, probe app 112 may calculate enthalpy. Probes 104 may also measure the static pressure across the indoor unit/components to be used for further calculations and/or as a method to read when the indoor blower motor is on/off. Probe app 112 may use one or more algorithms to calculate the effective heat transfer efficiency of HVACR system 105. For example, algorithms may be used to first calculate the enthalpy removal across the evaporator coil.

[0043] Algorithms may calculate the efficiency of the unit by calculating the sensible heat ratio, refrigerant capacity, temperature split, and contrast these results with a preset effective cubic feet per minute (CFM) range. An effective CFM range may be defined between 325 to 420 CFM calculated. However, this may not necessarily be the actual airflow across the indoor coil but effectively what the CFM would have to be to get a certain enthalpy, sensible heat ratio and temperature split at a given calculated refrigerant capacity in British thermal units per hour (BTU/h). Probe app may determine additional efficiency issues, low/high air flow across evaporator coil, dirty filters, undersized ductwork, electric heat running, etc. These calculations and efficiencies may be sent to one or more user devices and displayed.

[0044] Probe app 112 may be configured to also calculate variable speed compressor capacity in HVACR system 105 that include a compressor. To determine part load capacity or energy calculations such as SEER ratings, algorithms may take the rated load amps of the compressor and the actual amp draw to calculate compressor part load capacity. Probes 104 may include a one amp sensor per compressor and a one amp sensor to measure total amp draw to condenser fan motors and/or system components so that energy consumption can be computed. These calculations may be sent to one or more user devices and displayed.

[0045] Probe app 112 may also be configured to calculate an efficiency across an evaporator/condenser barrel and boiler. In this embodiment, fluid probes 104b may be placed at the barrel and measure inlet and outlet fluid temperatures. Using these temperatures, probe app 112 may calculate an effective flow rate per ton. The efficiency of the barrel may then be calculated by the deviation of the effective flow rate and gallon per minute per ton. Probe app may determine additional efficiency issues, such as fluid scale build up on the refrigerant tubes, low/high water flow, etc. These calculations and efficiencies may be sent to one or more user devices and displayed.

[0046] Probe app 112 may also be configured to calculate an efficiency across a cooling tower. In this embodiment, fluid probes 104b may measure an outdoor temperature, an outdoor relative humidity, an inlet fluid temperature and an outlet fluid temperature. Using these measurements along with the user inputted manufacturer designed range/approach temperatures and industry standard flow rate, probe app 112 may calculate an efficiency of the cooling tower. Probe app 112 may determine other efficiency issues, such as when it is too humid outdoors for the tower to function properly, scale build up, low/high water flow, etc. These calculations and efficiencies may be sent to one or more user devices and displayed.

[0047] Probe app 112 may further be configured to calculate indoor air quality variables, such as CO2 and/or CO levels, particle count, temperature, and volatile organic compounds. In this embodiment, air probes 104a may be placed in the return plenum of HVACR system 105. This air probe 104a may measure carbon dioxide levels, carbon monoxide levels, particle allergen count, and volatile organic compounds. These measured levels may be sent to one or more user devices and displayed.

[0048] Probe app 112 may also be configured to calculate the effective insulation value (R value) of a space. In this embodiment, air probes 104a may be placed in an air distribution system of HVACR system 105. Air probes 104a may take measurements and transmit data to probe app 112, which calculates an enthalpy change in a space and the efficiency of HVACR system 105 over a period of time while HVACR system 105 is running. This calculation may create a known British thermal unit (BTU) value of heat either removed or added to the space. HVACR system 105 may then be shut down and enthalpy values of the space measured again over a period of time. Probe app 112 may then calculate two outputs, effective space R value (ESRV) and duct space R value (DSRV). ESRV, effective space R value, is the R value of the conditioned space or the space being tested that is calculated using various heat transfer principles, weather data and real-time HVACR data analyzed in Probe App 112. The ESRV value is not adjusted for duct/building air leakage. DSRV, duct effective space R value, is the ESRV value adjusted for duct leakage information calculated or inputted into App 112.

[0049] Probe app 112 may further be configured to calculate an amount of duct leakage. In this embodiment, probe app 112 may calculate BTUs entering a space while HVACR system 105 is running and the heat gain/loss of the space in BTUs while the system is off. Probe app 112 may factor in real-time weather data during the time frame. Using this data, duct leakage percentage can be back calculated by using the calculated relationship between ESRV and DSRV as described in the section prior.

TABLE-US-00006 Ovr_Leak_Perc=(ESRV-DSRV)/ESRV Calc_Leak_CFM=Double(Real_time_CFM)*Ovr_Leak_Perc

[0050] Probe app 112 can be used to calculate Internal loads in a space. These calculations are essentially an interpolation of ESRV and DSRV values over time. Internal loads are essential to accurate energy calculations and are a constantly changing variable. Internal load calculations replace the use of fixed industry standard internal load values, reducing inaccurate estimations. These calculations can enable the possibility of real-time internal load readings, improving technology surrounding building and HVAC efficiency.

[0051] Finally, probe app 112 may be configured to calculate when an air filter needs to be replaced. In this embodiment, probe app 112 first calculates enthalpy change, system efficiency and static pressure change over time across an indoor coil. The device could zero out when the system is running with a reduced static pressure and a calculation of the sensible heat ratio to monitor if the system was running dehumidification and/or humidification. As the air filter gets dirty, the sensible heat ratio will slightly decrease due to reduced airflow across the coil and the static pressure will follow an exponential trend upwards. At a certain value point, the device algorithms can trigger a message indicating that it is time to replace the air filters. In addition, the air filter life percentage could constantly be displayed with the monitoring type device.

[0052] Processor 114 or similar can transmit and receive data via hardwired, cellular, Wi-fi and/or Bluetooth to a thermostat controller. This data can be displayed or used in calculations inside of the thermostat controller. The data is not limited to the use of the controller but may also be relayed from the controller to an external server for further use such as delivering energy data to approved parties such as energy companies.

[0081] FIG. 35 illustrates an example computer system 400 that may be employed in a system for measuring and displaying HVACR efficiencies. In some embodiments, the computer system 400 may be part of any of the systems or devices described in this disclosure. For example, the computer system 400 may be part of any of the probes 104, webserver 106, user device 108 and mobile application marketplace server 110 of FIG. 1.

[0082] The computer system 400 may include a processor 402, a memory 404, a file system 406, a communication unit 408, an operating system 410, a user interface 412, and an application 414, which all may be communicatively coupled. In some embodiments, the computer system may be, for example, a desktop computer, a client computer, a server computer, a mobile phone, a laptop computer, a smartphone, a smartwatch, a tablet computer, a portable music player, or any other computer system.

[0083] Generally, the processor 402 may include any suitable special-purpose or general-purpose computer, computing entity, or processing device including various computer hardware or software applications and may be configured to execute instructions stored on any applicable computer-readable storage media. For example, the processor 402 may include a microprocessor, a microcontroller, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a Field-Programmable Gate Array (FPGA), or any other digital or analog circuitry configured to interpret and/or to execute program instructions and/or to process data, or any combination thereof. In some embodiments, the processor 402 may interpret and/or execute program instructions and/or process data stored in the memory 404 and/or the file system 406. In some embodiments, the processor 402 may fetch program instructions from the file system 406 and load the program instructions into the memory 404. After the program instructions are loaded into the memory 404, the processor 402 may execute the program instructions.

[0084] The memory 404 and the file system 406 may include computer-readable storage media for carrying or having stored thereon computer-executable instructions or data structures. Such computer-readable storage media may be any available non-transitory media that may be accessed by a general-purpose or special-purpose computer, such as the processor 402. By way of example, and not limitation, such computer-readable storage media may include non-transitory computer-readable storage media including Read-Only Memory (ROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Compact Disc Read-Only Memory (CD-ROM) or other optical disk storage, magnetic disk storage or other magnetic storage devices, flash memory devices (e.g., solid state memory devices), or any other storage media which may be used to carry or store desired program code in the form of computer-executable instructions or data structures and which may be accessed by a general-purpose or special-purpose computer. Combinations of the above may also be included within the scope of computer-readable storage media. Computer-executable instructions may include, for example, instructions and data configured to cause the processor 402 to perform a certain operation or group of operations. These computer-executable instructions may be included, for example, in the operating system 410, in one or more applications, such as probes 104, webserver 106, probe app 112, processor 114, or user device 108 of FIG. 1, or in some combination thereof.

[0085] The communication unit 408 may include any component, device, system, or combination thereof configured to transmit or receive information over a network, such as the network 102 of FIG. 1.

The user interface 412 may receive input from a user and provide the input to the processor 402. Similarly, the user interface 412 may present output to a user.

[0088] The application 414 may be one or more computer-readable instructions stored on one or more non-transitory computer-readable media, such as the memory 404 or the file system 406, that, when executed by the processor 402, is configured to perform one or more actions of the system. In some embodiments, the application 414 (e.g., app) may be part of the operating system 410 or may be part of an application of the computer system 400, or may be some combination thereof.

[0089] Modifications, additions, or omissions may be made to the computer system 400 without departing from the scope of the present disclosure. For example, although each is illustrated as a single component in FIG. 35, any of the components 402-414 of the computer system 400 may include multiple similar components that function collectively and are communicatively coupled. Further, although illustrated as a single computer system, it is understood that the computer system 400 may include multiple physical or virtual computer systems that are networked together, such as in a cloud computing environment, a multitenancy environment, or a virtualization environment.

[0090] As indicated above, the embodiments described herein may include the use of a special purpose or general-purpose computer (e.g., the processor 402 of FIG. 35) including various computer hardware or software applications, as discussed in greater detail below. Further, as indicated above, embodiments described herein may be implemented using computer-readable media (e.g., the memory 404 or file system 406 of FIG. 35) for carrying or having computer-executable instructions or data structures stored thereon.

[0091] In some embodiments, the different components and applications described herein may be implemented as objects or processes that execute on a computer system (e.g., as separate threads). While some of the methods described herein are generally described as being implemented in software (stored on and/or executed by general purpose hardware), specific hardware implementations or a combination of software and specific hardware implementations are also possible and contemplated.

[0092] In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the present disclosure are not meant to be actual views of any particular apparatus (e.g., device, system, etc.) or method, but are merely example representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.

[0093] Terms used herein and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including, but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes, but is not limited to," etc.).

[0094] Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations.

[0095] In addition, even if a specific number of an introduced claim recitation is explicitly recited, it is understood that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." or "one or more of A, B, and C, etc." is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc. For example, the use of the term "and/or" is intended to be construed in this manner.

[0096] Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the summary, detailed description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" should be understood to include the possibilities of "A" or "B" or "A and B."

[0097] Additionally, the use of the terms "first," "second," "third," etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms "first," "second," "third," etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms "first," "second," "third," etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms first," "second," "third," etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term "second side" with respect to the second widget may be to distinguish such side of the second widget from the "first side" of the first widget and not to connote that the second widget has two sides.

[0098] The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention as claimed to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described to explain practical applications, to thereby enable others skilled in the art to utilize the invention as claimed and various embodiments with various modifications as may be suited to the particular use contemplated.
