Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. Provisional Patent Appl. Ser. No. 61/776,304, filed on Mar. 11, 2013, entitled “HVAC Zoning System with Distributed Intelligence,” the entire contents of which are hereby incorporated by reference herein.

BACKGROUND

Heating, ventilation, and air conditioning systems (hereinafter HVAC systems) are commonly used for thermal and ventilation control and in residential and commercial structures. Typically these systems include a heating unit, an air conditioning system, or both a heater unit and an air conditioning system configured to heat and/or cool air, or an alternate fluid, to a desired temperature. Further, a blower, compressor or other device, in fluid communication with the heater and/or air conditioning system, is used to direct the heated and/or cooled air to a desired location via one or more ducts, passages, or other conduits within the structure or positioned proximate thereto. In addition, present HVAC systems include at least one thermostat or other user-interface device permitting the user to control the temperature of the air delivered to a desired area, zone, or region of the structure.

Often, it is desirable to establish differential heating zones or regions within a structure. In the alternative, often it is desirable to maintain a constant temperature within a structure composed of multiple zones wherein the zones may have different thermal load characteristics. For example, in some commercial and residential settings, it may be desirable to have the temperature of a first zone within the structure maintained at a first temperature while a second zone within the structure may be maintained at a second temperature. Optionally, zones established within a structure may be heated and cooled at differing times. For example, within a residential structure, a bedroom may be heated or cooled more frequently during the night when in use rather than during the day when use is more sporadic. As such, these zoned heating architectures have been shown to increase user comfort while reducing energy usage by eliminating wasteful heating and cooling cycles in unused or under-used zones or regions within a structure.

Unfortunately, a majority of newly constructed and existing structures include non-zoned HVAC systems. Further, upgrading a non-zoned HVAC architecture to a multi-zone HVAC architecture has proven to be a time-consuming, labor intensive endeavor. Moreover, the cost of upgrading a non-zoned HVAC architecture to a multi-zone HVAC architecture can be cost prohibitive.

In light of the foregoing, a number of HVAC products have been produced seeking to add some zone temperature control to an existing structure. FIG. 1 shows an example of a prior art retrofit zoning system configured to enable some degree of zoned thermal control over a non-zoned HVAC system. As shown, the prior art HVAC system includes a heating/cooling unit 3 and a blower 5 coupled to the heating/cooling unit 3. Further, the prior art HVAC system 1 includes a duct system 7 having at first duct branch 9, a second duct branch 11, and a third duct branch 13 extending therefrom. The first duct branch 9 terminates within a first room 15. Similarly, the second branch 11 terminates within a second room 25, and the third duct branch 13 terminates within a third room 35. Further, a first register 17 positioned on or proximate the termination of the first duct branch 9. A first thermostat 19 is positioned within the first room 15. The first thermostat is in communication with the heating/cooling unit 3 and acts as a master control for the HVAC system 1, initiating the heating/cooling cycles at predetermined intervals or at pre-selected temperatures. Further, the retrofit HVAC system 1 includes a second register 27 positioned on or proximate the termination of the second duct branch 11 is in communication with a second thermostat 29 positioned within the second room 25, and a third register 37 positioned on or proximate the termination of the third duct branch 13 is in communication with a third thermostat 39 positioned within the third room 35. Typically, the second and third registers 27, 37, respectively, are in communication with the second and third thermostats 29, 39, respectively, while the first thermostat 19 is in communication with the heating/cooling unit 3. During, use, the user may set different temperature in the first, second, and third thermostats 19, 29, and 39. Typically, the first thermostat 19 is in communication with the heating/cooling unit 3 via a conduit 41. In contrast, the second and third thermostats 29, 39 are configured to transmit, via a conduit or, in the alternative, wirelessly transmit, a signal to the respective second and third registers 27, 37. As a result, the individual registers second and third registers 27, 37 may selectively open and/or close the register to permit or restrict the flow of warm or cold air from the duct into the room. In the alternative, the user may pre-set a thermostat in the room to a pre-determined temperature. Thereafter, the thermostat will monitor the temperature within the room and permit and/or restrict the flow of heated and/or cooled air via the register.

While these retrofit systems have proven somewhat successful in the past, a number of shortcomings have been identified. For example, the second and third thermostats 29, 39 within the second and third rooms 25, 35 rooms are incapable of controlling the central HVAC system. Thus, the second and/or third registers 27, 37 within the second and third rooms 25, 35 rooms may be open, however, the heating/cooling unit 3 may not be operating as the first thermostat 19 acts as a master controller. As a result, the temperatures within the second and third rooms 25, 35 rooms, which may be undesirably hot or cold, may remain unchanged until the first thermostat 19 initiates a heating/cooling cycle.

Thus, in light of the foregoing, there is an ongoing need for a HVAC zoning system wherein individual zoning modules are capable of distributed intelligence and control.

FIG. 13 shows an embodiment of the HIM shown in FIGS. 2-7. Those skilled in the art will appreciate that the HIM 150 and BIM 152 may offer similar capabilities. As such, the HVAC system 100 may include one or more HIMs 150, BIMs 152 or both. Further, the HVAC system 100 may be operated with a single HIM 150, thereby negating the need for a BIM 152. Similarly, the HVAC system 100 may be operated with a single BIM 152, thereby negating the need for a HIM 150. As such, for the sake of this discussion, the capabilities of the HIM 150 are understood to be equally applicable to the BIM 152, if present. While the following description discusses the attributes of the HIM 150, those skilled in the art will appreciate that the BIL 152 (if present) may offer similar capabilities. Moreover, the BIM 152 may offer a redundant control system should the HIM 150 fail. Further, those skilled in the art the HIM 150 and/or BIM 152 may, in combination with the registers 120, 130, 140, thermostats 122, 132, 142, and/or repeater modules 154, may cooperatively form a distributed intelligence and control system wherein data processing and control of the HVAC system resides in the HVAC network formed by the various components (HIM 150, BIM 152, registers 120, 130, 140, thermostats 122, 132, 142, and/or repeater modules 154) rather than a single component of the system. Thus, unlike prior art HVAC systems, the HVAC system 100 described herein may form a multi-redundant system via a distributed computer network architecture.

As shown in FIG. 13, in one embodiment the HIM 150 provides an internal computer network (intranet) for the various components of the HVAC system 100. More specifically, unlike prior art HVAC systems, the HIM 150 is configured to be capable of communicating with each thermostat (e.g. thermostat 122, 132, 142 of FIG. 2) and/or each register 120, 130, 140. In one embodiment, the HIM 150 is configured to communicate with at least one thermostat and/or register wirelessly. Optionally, the HIM 150 may communicate with the thermostats and/or registers via at least one conduit. In one embodiment, the HIM 150 comprises a computer system or device. As such, the HIM 150 may include at least one processor, communication devices or system, power source, battery system, sensor, and the like. For example, in one embodiment, the HIM 150 includes at least processor in communication with or in substitution for the control circuit of the H/C unit 102, at least one communication system in communication with the at the thermostats (e.g. thermostat 122, 132, 142), and a memory device to store data. Further, the HIM 150 may be configured to user accessible via at least one thermostats (e.g. thermostat 122, 132, 142), a computer network, and the like. Optionally, the HIM 150 may be in communication with various external computer or communication networks. For example, in one embodiment the HIM 150 is in communication with various sensors, including, for example, fuel level sensors, faults detectors, fire detectors, CO₂ detectors, air sampling sensors, radon detectors, and the like. As such, the HIM 150 may be easily configured to independently contact maintenance systems, emergency response systems, and the like, either wirelessly or via a conduit.

As shown in FIG. 13, the HIM 150 includes a HIM body 220 having a first surface 222 formed thereon. The at least one information display 224 may be formed on the first surface 222 of the HIM body 220. Further, in the illustrated embodiment, at least one user interface device 226 may be positioned on the HIM body 220. Exemplary interface devices include, for example buttons, switched, and the like. Optionally, the HIM body 220 need not include a user interface device 226. For example, optionally, the information display 224 may comprise a touch screen device thereby negating the need for an additional user interface device 226.

The following paragraphs will describe one method of creating a zoned HVAC architecture having distributed intelligence using the HVAC system 100 shown in FIGS. 2 and 3. The HIM 150 (and/or BIM 152 as each may be used in combination or exclusively) is electronically coupled to or replaces the control unit of the H/C unit 102. As a result, the HIM 150 provides the data infrastructure configured to provide and receive information from at least one of thermostats 122, 132, 142, the registers 120, 130, 140, and/or both. For example, in one embodiment, the HIM 150 is in wireless communication with the thermostats 122, 132, 142, while the thermostats 122, 132, 142 are in communication with the HIM 150 and at least one register 120, 130, 140. As such, the HIM 150 may communicate with the thermostats 122, 132, 142 via a wireless network, computer network, conduit, or the like.

With the HIM 150 coupled to and controlling the H/C unit 102 and available via at least one communication network (e.g. wireless HVAC network), the user positions at least one thermostat in each room or zone. Typically, a single thermostat is positioned in each room or zone. Optionally, particularly in large areas, multiple thermostats may be positioned within a single room or zone. As shown in FIG. 2, each room 118, 128, 138 includes a single thermostat 122, 132, 142, respectively, located therein. The user may the access the HVAC network from each thermostat 122, 132, 142, thereby creating an individual temperature profile for each room. For example, the user may establish room temperatures, time-dependent room temperature profiles, HVAC cycle times, flow rates, and the like via the thermostat 122, 132, 142. As a result, each thermostat 122, 132, 142, is associated with each room 118, 128, 138.

With the thermostat registered with the HIM 150, the user may associate the individual registers 120, 130, 140 with the corresponding thermostat 122, 132, 142. For example, the registers 120, 130, 140 may communicate with the thermostats 122, 132, 142 via the HVAC network, via an alternate wireless network, or via a conduit. Once the registers 120, 130, 140 are associated with their corresponding thermostats 122, 132, 142, the user simply replaces the existing registers coupled to the duct work of the structure with the registers 120, 130, 140 Unlike prior art device, each thermostat is capable of directly communicating with the HIM 150 and any registers associated with that thermostat. Moreover, unlike prior art retrofit zoning systems, the HVAC of the instant patent application includes multiple thermostats, each capable of not only selectively controlling the opening and closing of the registers associated therewith, but individually directing the heating and cooling cycling of the H/C unit 102. As such, unlike prior art HVAC system which utilized a single master controller thermostat to control the H/C unit and numerous slave thermostats to open and close registers, the present system offers true distributed intelligence wherein the master controller is formed collectively by the HIM 150, and the thermostats 122, 132, 142.

The first room 320 includes a floor 322 having at least one fluid circuit 324 positioned therein. The fluid circuit 324 is in coupled to the manifold 310 via the valved outlet 312. In one embodiment, the fluid circuit 324 is manufactured from cross-linked polyethylene (e.g. PEX), polymer materials, copper, or the like. Further, at least one thermostat 326 is located with the room 320.

Similarly, the third room 330 includes a floor 332 having at least one fluid circuit 334 positioned therein. The fluid circuit 334 is in coupled to the manifold 310 via the valved outlet 314.

In the illustrated embodiment, the HIM 350 is positioned on the pump 306. Like the previous embodiment, the HIM 350 and first, third, and third thermostats 326, 336, 346 cooperatively form a master controller configured to independently regulate the temperature of each room of the structure. As such, like the previous embodiment, the HIM 350 and thermostats 326, 336, 346 are configured to communicate via at least one HVAC network, wireless network, or via at least one conduit. In addition, at least one of the HIM 350 and thermostats 326, 336, 346 may be configured to selectively open and close individual valved outlets 312, 314, 316 thereby permitting separate control of the temperature of each room. As such, the valved outlets 312, 314, 316 may also include at least one communication device thereon in in communication therewith. For example, at least one valve controller 352 may be positioned proximate to the manifold 310 and configured to selectively open and close individual valved outlets 312, 314, 316 on direction from at least one of the HIM 350 and thermostats 326, 336, 346.
