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, a...
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 ther...
