Definitions
- thermoelectric subcooler Accordingly, there is a need for an improved subcooler that does not require the need for a secondary loop or a secondary liquid.
- the method and apparatus of the present invention avoids the need for a secondary loop or a secondary liquid through the use of a thermoelectric subcooler.
- a subcooler for a vapor compression cycle having a refrigerant comprises a conduit and one or more thermoelectric modules.
- the conduit being in fluid communication with the vapor compression cycle for flow of the refrigerant therethrough.
- Each of the one or more thermoelectric modules has a cold side in thermal communication with an inner volume of the conduit for subcooling the refrigerant.
- a vapor compression system comprising a compressor, a condensor, and an evaporator connected to each other via a conduit and a subcooler.
- the subcooler has one or more thermoelectric modules connected to the conduit, wherein each of the one or more thermoelectric modules has a cold side in thermal communication with an inner volume of the conduit for subcooling refrigerant circulating therethrough.
- a method of subcooling a vapor compression cycle is provided.
- thermoelectric modules can have a warm side in thermal isolation from the inner volume of the conduit.
- the one or more thermoelectric modules can be embedded in the conduit, and the cold side can directly contact the refrigerant.
- the one or more thermoelectric modules can further comprise a secondary heat exchanger for indirect heat exchange with refrigerant.
- the one or more thermoelectric modules can comprise a thermoelectric heat exchanger.
- the thermoeletric heat exchanger can be an air or liquid thermoelectric heat exchanger.
- the one or more thermoelectric modules can be connected to an outer surface of the conduit and in thermal communication with the refrigerant.
- the subcooler can further comprise a fan that provides air flow in thermal communication with a warm side of the one or more thermoelectric modules.
- Vapor compression cycle 10 uses a thermoelectric subcooler 15 to subcool refrigerant of the vapor compression cycle 10.
- Subcooler 15 may be used for vapor compression cycles such as, for example, supermarket display cases having low coefficient of performance (COPs), e.g., less than 3, as well as any other types of refrigeration cycles of large or small scale.
- COPs coefficient of performance
- chilled water coils in air handlers or fan coils may also be precooled when a transient change in their cooling or humidity removal performance is warranted.
- Subcooler 15 thermoelectrically subcools the refrigerant as the refrigerant circulates through second conduit 45 from condenser 30.
- Third conduit 47 connects subcooler 15 to thermal expansion valve 35.
- the refrigerant circulates through third conduit to thermal expansion valve 35 as represented by arrow 46.
- thermal expansion valve 35 decreases a pressure of the refrigerant to a mixed liquid and vapor.
- the the refrigerant enters evaporator 25 from fourth conduit 48 as represented by arrow 49.
- Evaporator 25 substantially vaporizes the liquid by heat transfer provided from a refrigerated space 75.
- a rejection space 70 is underneath evaporator 25 so that heat from evaporator 25 is not rejected to refrigerated space 75.
- the refrigerant exits evaporator 25 to a fifth conduit 50 as represented by arrows 51.
- the refrigerant enters compressor 20 from fifth conduit 50.
- Compressor 20 compresses the refrigerant and completes vapor compression cycle 10.
- Thermoelectric modules 17 may be embedded in second conduit 45 so that a cold side or face is facing inwardly into an inner volume of second conduit 45 and a warm side or face is facing away from the inner volume of second conduit 45.
- the cold side of each of the thermoelectric modules 17 is in thermal contact with the inner volume of second conduit 45 to provide contact cooling of the refrigerant, while the warm side is in thermal isolation from the inner volume of second conduit 45.
- thermoelectric modules 17 cools the refrigerant, which is being circulated through second conduit 45.
- Second conduit 45 can be made of thermally conductive materials, however, the material can be varied based upon the particular cooling needs and other factors related to vapor compression cycle 10.
- the number of thermoelectric modules 17 that are used in second conduit 45 can be varied based upon the particular cooling needs and other factors related to the subcooler 15.
- the particular number of thermoelectric modules 17, as well as the structure or method of making the inner surface or inner portion of second conduit 45 thermally conductive, can be varied based upon the particular cooling needs and other factors related to the display vapor compression cycle 10.
- thermoelectric modules 17 The particular type, including materials, dimensions and shape, of thermoelectric modules 17 that are utilized can vary according to the particular needs of the subcooler 15. Preferably, the dimensions and shape of the cold side and the warm side of the thermoelectric modules 17 maximize thermal contact or communication, e.g., surface area, between second conduit 45 and the cold side, as well as between the air outside of second conduit 45 and the warm side.
- the particular structure or method of providing energy source 18 to thermoeiectric modules 17 can be varied according to the particular needs of subcooler 15.
- Thermoelectric modules 17 may be a thermoelectric device powered directly by a DC source, such as, for example, batteries, a portable fuel cell, photovoltaic, and the like, without need for AC-DC conversion.
