Abstract
A swimming pool heating system includes in sealed tank, a refrigerant cooling coil system contained within the sealed tank and a water flow distribution manifold within the refrigerant cooling coil system. Cool swimming pool water is pumped through the water flow manifold such that is imparts a cyclical flow of water over the refrigerant cooling coil system. The warmth of the warmed refrigerant is imparted to the cool swimming pool water and the warmed swimming pool water then exits the water flow manifold and is returned to the swimming pool.
Claims16
A system for heating liquid which uses the waste heat from the refrigerant in an air conditioning or refrigeration system, said system comprising in operative combination:
- a sealed tank having water inlet and outlet connections and refrigerant inlet and outlet connections;
- a refrigerant cooling system contained within said sealed tank and connected to said refrigerant inlet and outlet connections;
- a substantially cylindrical water flow manifold contained within said refrigerant cooling coil system and connected to said water inlet and outlet connections, said eater flow manifold having a plurality of substantially tangentially formed holes positioned and arranged to impart a substantially cylindrical flow of liquid within said sealed tank and over said refrigerant cooling coil system;
- whereby waste heat from the refrigerant in the air conditioning or refrigeration system is transferred to the liquid to be heated through said refrigerant cooling coil system.
A swimming pool water heating system which uses the waste heat from the refrigerant in an air conditioning system, said system comprising in operative combination:
- a pump;
- a heater, including:
- a sealed tank having water inlet and outlet connections and refrigerant inlet and outlet connections;
- a refrigerant cooling coil system contained within said tank and connected to said refrigerant inlet and outlet connections;
- a substantially cylindrical water flow manifold contained within said refrigerant cooling coil system and connected to said water inlet and outlet connections, said water flow manifold having a plurality of substantially tangentially formed holes positioned and arranged to impart a substantially cylindrical flow of swimming pool water within said sealed tank and over said refrigerant cooling coil system;
- means for coupling said pump to said heater;
- whereby swimming pool water is caused to flow to said heater by said pump and the waste heat from the refrigerant in the air conditioning system is transferred to the swimming pool water through the refrigerant cooling coil system within said sealed tank.
