HOT-WATER SUPPLY SYSTEM HAVING HEAT RECOVERY PASSAGE

摘要

In an ordinary house or other facilities equipped with an air-conditioning system and a hot-water supply system, the heat of a radiator for radiating the heat of a coolant compressed in the compressor of the air-conditioning system is recovered to heat the water reserved in the hot-water tank of the hot-water supply system, thereby to make effective use of the heat to be radiated and to promote the heating promotion effect of the water reserved in the hot-water tank. The hot-water supply system comprises a closed type hot-water tank supplied with the water and kept in a predetermined pressure state. Further comprised are a water heater for heating the water of the hot-water tank by circulating it to a heating device, and a cooling/heating unit having an air conditioning function of a circulating cycle, in which it releases the heat of the coolant compressed by the compressor in the radiator, and in which it evaporates the coolant in the evaporator through an expanding device and returns the same to the compressor. Still further comprised is a heat recovery passage for reserving the water heated by the heat of the coolant passing through the radiator, in the hot-water tank so that the heat to be radiated by the radiator may be recovered by the hot-water supply system.
