초록 ▼

In an air conditioning system for a load, air is used as the refrigerant, and identical components including a turbocompressor and a regenerative heat exchanger are used for both cooling in the refrigeration mode and heating in the heat pump mode. A plurality of valves are arranged so that in the refrigeration mode the refrigerant air operates in a closed dry air loop to avoid problems associated with moisture. In the heat pump mode the valves are arranged to cause the refrigerant air to operate open loop by using ambient air as the input to the cycle, and avoiding icing problems by rejecting the refrigerant air, together with any ice present, back into the ambient. Operation closed loop in the refrigeration mode and open loop in the heat pump mode results in maximum cycle efficiency with minimum difficulty caused by moisture entrained in the refrigerant air.

A combined air cycle heat pump and refrigeration system for a load comprising: a source of low pressure refrigerant air at essentially ambient pressure, said refrigerant air being ambient air when said system is operating in the heat pump mode and being air returned from said load when said system is operating in the refrigeration mode; a turbine driven compressor receiving said refrigerant air and increasing the temperature and pressure thereof; means for conducting said compressed refrigerant air to said turbine for expansion therein and discharge therefrom whereby said refrigerant air is reduced in temperature; means for conducting the refrigerant air discharged from said turbine directly to the ambient when said system is operating in the heat pump mode, and for conducting the refrigerant air discharged from said turbine directly to said load when said system is operating in the refrigeration mode; a regenerative heat exchanger connecting through heat transfer surfaces within said regenerative heat exchanger the source of low pressure refrigerant air with the compressed refrigerant air upstream of said turbine whereby said compressed refrigerant air rejects some of its heat to said low pressure refrigerant air from said source and reduces the temperature of the compressed refrigerant air fed to said turbine so as to maximize the reduction in the temperature of the refrigerant air discharged from said turbine; additional heat exchange means downstream of said compressor and upstream of said regenerative heat exchanger on the high pressure side thereof, said compressed refrigerant air passing through said additional heat exchange means; an additional fluid, said fluid being fluid returned from said load when said system is operating in the heat pump mode and said fluid being ambient air when said system is operating in the refrigeration mode; means for passing said fluid through said additional heat exchange means in heat exchange relation with said compressed refrigerant air whereby said fluid absorbs heat from said compressed refrigerant air; and means for returning said fluid to supply heat to said load when said system is operating in the heat pump mode and returning said fluid to ambient when said system is operating in the refrigeration mode.
