HYBRID HOT WATER SUPPLYING SYSTEM USING SOLAR COLLECTOR AND HEAT PUMP TYPE AIR CONDITIONER

摘要

PURPOSE: A hybrid hot water supply system using a solar heat collector and a heat pump air-conditioner is provided to improve the production of hot water in the summer season by obtaining an additional hot water source through an outer heat exchanger of a heat pump air-conditioner. CONSTITUTION: A hybrid hot water supply system using a solar heat collector and a heat pump air-conditioner comprises a flat or evacuated tube type solar collector(1), a heat pump air-conditioner(2), a dual structure thermal storage tank(3), and a hot water supply unit(4). The solar collector collects solar energy to produce hot water, using a solar heat exchanger(16) formed in a part of a pipe in which heated thermal media are circulated. The heat pump air-conditioner comprises an outdoor heat exchanger, an indoor heat exchanger(22), an expansion valve(23), a compressor(24), and a four-way valve(25). The outdoor heat exchanger comprises a first outdoor heat exchanger(21a) and a second outdoor heat exchanger(21b). The dual structure thermal storage tank comprises a solar collector side thermal storage tank in which the solar heat exchanger of the solar collector is installed and a heat pump air-conditioner side thermal storage tank in which the second outdoor heat exchanger of the heat pump air-conditioner is installed. The dual structure thermal storage tank stores the water produced through selective heat exchange with supplied water according to the climate condition. The hot water supply unit supplies hot water produced in the thermal storage tanks or the mixture to a used place.
