ABSTRACT:
An air-conditioning and hot-water supplying system has a dual function water-heating heat exchanger; a heat pump circuit circulates a heat-transmitting medium for air conditioning the interior of a housing. The heat pump circuit includes a compressor driven by a prime mover. The system also includes a hot-water circulation circuit having a tank for storing hot water and a pump for circulating water to be stored therein. The water-heating heat exchanger comprises three concentric, different length pipes including an outer pipe, a first heat transfer pipe disposed in the outer pipe, and a second heat transfer pipe disposed in the first heat transfer pipe. Hot water from the hot water circulation circuit flows between the outer and the first heat transfer pipes. Cooling water from a prime mover cooling circuit flows between the intermediate first heat transfer pipe and the innermost second heat transfer pipe. The heat-transmitting medium flows through the second heat transfer pipe. Thus, heat is transferred between the prime mover cooling water and the water in the hot-water circulation circuit and also between the prime mover cooling water and the heat-transmitting medium.
