ABSTRACT:
A refrigeration system is disclosed which utilizes the rejected heat from the condenser of an air conditioner to heat a second medium such as water for a swimming pool. A control is provided to maintain the temperature of the pool within a given range without degrading the performance of the air conditioning system and actually improving its economy and efficiency of operation. A heat exchanger, to place the second medium in heat exchange relationship with the refrigerant, is placed between the condenser unit and the expansion valve of the refrigeration system. The temperature of the refrigerant entering the heat exchanger is controlled by the on and off cycling of a fan to selectively move air across the coils of the condenser responsive to the temperature of the second medium.
