Claims
- 1. An indoor space heating and cooling system comprising:
- a refrigeration circuit having, in series relationship, a compressor and separate indoor and outdoor refrigeration circuit heat exchangers;
- a heat engine for driving said compressor while rejecting heat;
- a supplemental heat distribution circuit having indoor and outdoor rejected heat exchangers and means for conducting heat rejected from said heat engine to one or the other of said rejected heat exchangers;
- first control means in said refrigeration circuit, said first control means being selectively settable to a cooling condition for directing refrigerant from said compressor first through said outdoor and then through said indoor refrigeration circuit heat exchangers and back to said compressor or to a heating condition for directing refrigerant from said compressor first through said indoor and then through said outdoor refrigeration circuit heat exchangers and back to said compressor; and
- second control means in said supplemental heat distribution circuit, said second control means being selectively settable to a cooling condition for directing rejected heat from said heat engine to said outdoor rejected heat exchanger when said first control means is in its cooling condition or to a heating condition for directing rejected heat from said heat engine to said indoor rejected heat exchanger when said first control means is in its heating condition, said heat engine being of a type employing throughout its cycle a gas as its working fluid and wherein the working temperatures of such gas are substantially higher than the temperature desired to be maintained in the indoor space conditioned by said system.
