Comfort Conditioning System. The heating and cooling of building structures is accomplished by driving an air conditioning system compressor with an internal combustion engine. In the heating mode, engine waste heat and condenser rejected thermal energy are used to supply heat to the structure and the total thermal energy rejected by the condenser is increased by feedback of energy from the condenser to the evaporator to create an artificial cooling load.
Heating is, accordingly, accomplished without reversal of the refrigerant system.
