7 U 2009/ A1 Apr. 16, 2009 HGH EFFICIENCY HYBRD AIR CONDITIONING YTEM BACKGROUND OF THE INVENTION Field of the Invention 0002 The invention relates to a hybrid air conditioning system that uses conventional air conditioning equipment to provide primary temperature control and thermoelectric cool ing and/or heating devices to provide localized temperature control Description of Related Art The efficiency of hydronic cooling systems is dependent upon the chilled water setting temperature or the evaporator setting temperature. For a given system and a fixed ambient environment, the higher the temperature setting, the greater will be the system efficiency. imilarly, the efficiency of a heating system is directly dependent upon the condenser or heating water temperature in a conventional system. In this instance, again, for a given system and a fixed ambient envi ronment, the lower the temperature setting the greater the system efficiency will be A thermoelectric device consists of semiconductor materials that transfer heat from the first side or heat source side to a second side or heat sink side as charge carriers move through the materials. Thermoelectric cooling and heating systems operate at higher efficiency when there is a small temperature difference between the heat source side and the heat sink side. A thermoelectric device is also more respon sive to the change in temperature settings, higher reliability and lower maintenance needs because they have fewer mov ing parts than conventional systems. uch systems are also more responsive to temperature settings, lower in weight, quieter and can be more accurately controlled Vapor compression and absorption based air condi tioning systems are used for cooling residential and commer cial buildings where multiple Zone temperature control is the most efficient mode and provides the greatest comfort to occupants. This on-demand Zoning comfort control is diffi cult and expensive to realize using a conventional air condi tioning system because the entire evaporator and condenser units have to be activated whenever there is a cooling need. A hybrid air conditioning system incorporating thermoelectric cooling devices has the capability to operate for partial cool ing without running the prime cooling system at all times. uch a hybrid air conditioning system will achieve both effi ciency and comfort for users Furthermore, by applying a hybrid cooling system that incorporates both conventional air conditioning and ther moelectric cooling, the conventional equipment can operate at a higher evaporator temperature or chilled water tempera ture compared to non-hybrid equipment. Therefore the cool ing system is able to operate at a higher cooling efficiency. imilarly, such a hybrid system for heating allows its conven tional equipment to operate at a lower condenser or heating water temperature compared to the conventional application and the thermoelectric devices may operate at mall tempera ture differential condition, whereby the hybrid system oper ates at a higher efficiency Accordingly, there is a need for an air conditioning system that incorporates a bulk conventional system with a thermoelectric distributed system that enhances overall sys tem efficiency and improved comfort level by utilizing waste heat and/or cool and redirected electricity in a more reliable and responsive system for Zoned temperature control. UMMARY OF THE INVENTION It is an object of the present invention to provide a hybrid system for an air conditioned space that uses conven tional air conditioning equipment and thermoelectric heating and cooling devices It is also an object of the present invention to provide a hybrid system for an air conditioned space that has thermo electric elements that can selectively provide Zoned heating and/or cooling in the air conditioned space It is a further object of the present invention to provide a hybrid system for an air conditioned space that uses conventional and thermoelectric heating/cooling elements to reduce the overall energy consumption of the air conditioned pace It is still yet a further object of the present invention to provide a hybrid system for an air conditioned space that uses conventional and the waste heat from thermoelectric heating/cooling elements to enhance the overall efficiency of the hybrid system It is still yet a further object of the present invention to provide a hybrid system for air conditioning that is con trolled by occupants demand with the aid of sensors to enhance the efficiency of the cooling system. BRIEF DECRIPTION OF THE DRAWING 0014 FIG. 1 illustrates a block diagram of a conventional air conditioned space; (0015 FIG. 2 illustrates a block diagram of the hybrid system for the air conditioned space of the present invention; 0016 FIG. 3 illustrates a diagram of the operation of a thermoelectric element of the hybrid system of FIG. 2. according to the present invention; 0017 FIG. 4 illustrates a schematic view of a hybrid air conditioned space according to the present invention; and (0018 FIG. 5 illustrates a schematic view of a hybrid air conditioning system that uses return air as the heat sink of a thermoelectric cooling unit and is controlled by sensors. DETAILED DECRIPTION OF THE INVENTION 0019 Referring to FIG.1, there is a block diagram of an air conditioned space 10, e.g. a large office, that is heated and cooled using a conventional air conditioning system of prior art. A conventional space cooling system is operated using a compressor, and evaporator, an air diffuser and a thermostat (not shown). pace 10 has an interior space 15 that may be subdivided into several units, e.g. rooms 20, 25, 30 and 35, having temperatures T.T.T. and T, respectively. In space 10, Trepresents the temperature to which a thermometer is set, for a cooling scenario. Each of the temperatures T, T T. and T are equal to the temperature of T of the larger space. Rooms 20, 25, and 35 each have thermostat. Raising the temperature T to a temperature above T in room 20 will be very difficult because of conduction from adjacent rooms 25, 30 and 35 and the entire space 10 are relatively cool. The response time to increase the temperature would be long. imilarly, in an air conditioned space in which the tempera ture a lower temperature is desired, the same inefficiency persists. Lowering a temperature in a localized space in a large hot area will not only consume energy, but the lowered

8 U 2009/ A1 Apr. 16, 2009 temperature, by conduction to adjacent spaces will cool those areas to a degree as well, thus making the conventional sys tem produce more heat Referring to FIG. 2, a diagram showing the hybrid system 45 of the present invention is shown. Hybrid system 45 incorporates a conventional air conditioning system 46 and a localized thermoelectric air conditioning system 48. In this diagram, air conditioned space 50, e.g. an office building space, is set at a temperature T. pace50 contains several spaces, e.g. office rooms. paces 60, 65, 70 and 75 are set at temperatures T, T, T- and T. respectively. Further spaces 60, 65, 70 and 75 each contains a thermoelectric module 80, 85,90 and 95, respectively. Thermoelectric modules 80,m 85, 90 and 95 are controlled by localized thermoelectric air con ditioning system 48. Each thermoelectric module is capable of generating either a cooling effect or a heating effect depending on the direction of the flow of current from its power source. Hybrid system 45 also has a temperature sen sor 49 to monitor the overall temperature in the building paces Referring to FIG. 2 and 3, thermoelectric module 80 located in room 60 is shown operating in a cooling mode. In thermoelectric module 80, a DC voltage from a power source 115 is applied across module 80 having a series of P and N junctions 100. Current 110 flows in the direction shown. Junctions 100 in thermoelectric module 80 absorb heat from a surface 105 and release the heat to a surface 110 at the opposite side of module 80. urface 105 where the heat energy is absorbed becomes cold and the opposite surface 110 where the heat energy is released becomes hot. This heat pumping phenomenon, known as the Peltier effect, is com monly used in thermoelectric refrigeration. Heat exchangers 125 and 135 are used to transport cool air or heat away from thermoelectric module 80. In this scenario, forced air from fan 130 can be used to cool room 60 as it blows through heat exchanger 125. imilarly, forced air from fan 140 is used to transport heat from heat exchanger 135 to heat other rooms 65, 70 or 75 or conventionally air conditioned space 50. By using the waste heat from thermoelectric module 80, the efficiency of conventional air conditioned system is increased. Further, the conventional air conditioning system does not have to exclusively produce heat to heat other rooms, but can utilize heat from module 80 to heat the other rooms. Modules 85,90 and 95 would operate in the same fashion in a heating operation, except that the current 110 would flow in the opposite direction The benefit of using thermoelectric modules in either a cooling application or a heating application in a localized space within a larger air conditioned space is that such modules contribute to the overall system efficiency of the hybrid system. Additionally, such a system will have reduced energy consumption costs associated with the con ventional portion of the system. Further, the responsiveness of a system in achieving a desired temperature using thermo electric modules is much greater than the responsiveness of conventional air conditioning system elements Referring to FIG. 2, a user in room 60 may want a cooler temperature T in comparison to Tin space 50. In this example, the desired temperature T is 68 F, while T. is 72 F. When thermoelectric module 80 is activated in the cooling mode, a surface 100 of thermoelectric module 80 becomes cool to lower temperature T. Concurrently, ur face 105 becomes hot and contributes to the warming of spaces 50, and rooms 85, 90 and 95 by conduction. Heat generated by thermoelectric module 80 reduces the amount of work that conventional system must provide to keep tempera ture T at 72 F Referring to FIG. 3 and 4, a schematic of diagram of an office building incorporating a high efficiency system 200 is shown. ystem 200 has a light duty conventional roof top system 205 for conventional air conditioning. ystem 200 has a compressor, an evaporator, a linear diffuser and other components associated with a conventional air conditioning system. Room 210 has a thermoelectric module 215 for local ized temperature control. When occupants of room 210 would like a warmer room temperature than the temperatures in the surrounding rooms, thermoelectric module 215 is acti vated to raise the local temperature in room 210. Cool air generated concurrently by thermoelectric device 215 will be distributed to rooms 220, 225 and 230, depending upon cool ing needs. Accordingly, system 200 would not have to work to maintain the lower temperature because of the waste gener ated by module 215. Athermal sensor placed in common area 240 would monitor the temperature of the entire space in response to cool air from thermoelectric module 215, and would accordingly, adjust the amount of cooling to be pro vided by conventional system 200. Monitor 245 optimizes the performance of system 200 in response to adjustments made to thermoelectric modules in each of rooms 220, 225 and 230. Monitor 245 offsets the amount to cooling or heating that conventional components of hybrid system 200 produce depending upon the waste heat provided by thermoelectric modules Another embodiment of a hybrid air conditioning system 300 of the present invention is shown in FIG.5. In this embodiment, system 300 has a conventional outdoor air con ditioning component 305, preferably situated on the roof of a building, and a thermoelectric component 315 located adja cent air conditioned space 310. Thermoelectric component 315 has a side 320 and a side 325. When the hybrid system 300 is in a cooling mode, cool air is absorbed at side 320 and heat is released at surface 325. Conventional component 305 provides the primary cooling that may be set at a slightly higher temperature than the desired temperature. Cool air from conventional component 305 is forced through vents 335 by fans (not shown) to air conditioned space 310. When thermoelectric component 315 is activated, side 320, in com munication with air pre-conditioned, produces cold air to further contribute to the cooling of the space. Return air 340 is used as the heat sink for thermoelectric component 315. A portion of the return air 340 is also circulated from air con ditioned space 310 to refresh the air. The air cooled by the conventional unit 305 can be further cooled by a thermoelec tric component 315 to a desired temperature or outdoor air 345 can be cooled directly by the thermoelectric unit depend ing the requirement of cooling capacity that is determined by the demand of occupants. Hybrid system 300 is preferably activated by sensor 350 such as temperature and air freshness sensor, e.g. a carbon dioxide sensor While the embodiment of FIG. 5 was shown in a cooling mode, a similar configuration of components could also be used in a heating application. Hybrid system 300 is converted to a heating mode by changing the direction of flow of electricity in the thermoelectric component 315 and by changing the setting on conventional system While the instant disclosure has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes
