  • Air conditioning heat recovery arrangement
    Patent number: 6536221
    Abstract: In combination with a residential air conditioning system and a water fixture with a water recirculation loop, such as a swimming pool, a refrigerant-to-water heat exchanger having a tank with water inlet and outlet connections to said water recirculation loop, and a condenser coil with refrigerant inlet and outlets for connection respectively to the compressor and the condenser of the air conditioning system. Whenever the air conditioning system comes on, a control circuit turns on the pump independent of the usual timer and connects the refrigerant-to-water heat exchanger inlet to the compressor of the air conditioning system.
