ABSTRACT:
A combination air conditioner and pool heater. The air conditioner is a conventional house air conditioner which includes a condensing unit located outside the house and comprising a compressor, an air cooled coil, and a external fan directing air across the air-cooled coil; the conventional air conditioner also includes an evaporator unit inside the house, the evaporator unit comprising an evaporator coil and an internal fan for blowing air across the evaporator coil to discharge cool air into the house; the pool being a conventional outdoor swimming pool having a circulating pump for withdrawing water from the pool and for returning water to the pool; combined with the conventional air conditioning system and the conventional swimming pool are a coaxial heat exchanger coil having an outer conduit and an inner conduit disposed in heat exchange relation with each other, a bypass duct is connected from the pump to the outer conduit of the coaxial heat exchanger, the outer conduit being connected to a discharge pipe for discharging water back into the pool, and a pair of valves connected to the compressor for alternately supplying hot compressed liquid to the air-cooled heat exchanger or to the inner conduit of the coaxial heat exchanger coil. Controls are provided for the proper sequencing of the operation of the various instrumentalities and to insure that the external fan is off when refrigerant is passing though the inner conduit of the coaxial heat exchanger.
