PURPOSE: A heat pump system is provided to implement hot water supply and cooling simultaneously in the summer season and hot water supply, heating, and hot air supply simultaneously in the winter season. CONSTITUTION: A heat pump system comprises an outdoor unit system(300), an indoor unit system(400), and a regenerator system(500). The outdoor unit system comprises compressors(1,2), a control valve(30), a four-way valve(5), an outdoor unit, expansion valves(20,21,22,23), a main control unit. The compressors compress refrigerant gas to high pressure and high temperature. The expansion valves expand the liquid coolant of high pressure and high temperature condensed by the condenser to the liquid coolant of low pressure. The four-way valve switches between cooling and heating. The indoor unit system comprises indoor units(50,51,52,53,54,55), expansion valves(24,25,26), and an indoor controller. The regenerator system comprises a hot water heat exchanger(40), a heating water heat exchanger(41), water tanks(7,8), and a water controller and stores hot water and heating water. |
