ABSTRACT:
An air conditioning system for an enclosed space, capable of operating as a heat pump in the winter and as a refrigerator in the summer, of the type employing a unitary compressor and expander having a common rotor with vanes defining enclosed compartments for positive compression and expansion of air. An indoor heat exchanger and outdoor heat exchanger are provided with one being connected between the outlet port of the compressor and the inlet port of the expander and the other being connected from the outlet port of the expander to the inlet port of the compressor thereby to complete a loop which is charged with air. Valves are interposed for effectively interchanging the connections of the heat exchangers so that the indoor heat exchanger is used for warming in winter and cooling in summer. The outdoor heat exchanger is in the form of a solar-directed panel having a heat absorption surface and air passages for convection cooling. Means are provided for exposing the heat absorption surface and closing the air passages in the winter and for shielding the absorption surface and opening the air passages in the summer. A cold storage device is provided to serve as a heat source and to freeze water during the winter and with the melting of the resulting ice augmenting cooling effect during the summer. A heat storage device is also used to store heat during a winter day for release during the winter night. The loop is pressurized with air, the pressure being correctively varied by thermostatic control to vary the heat rate, thereby to maintain a set temperature both winter and summer in the enclosed space. The air in the loop is preferably moistened and a regenerator is optionally provided to increase the capacity of the system under extreme temperature conditions.
