Abstract

The invention discloses a heat pump system, which comprises a compressor (1), a hot water heat exchanger (2), a throttling device (3) and an outdoor heat exchanger (4) sequentially arranged in a refrigerant circulation circuit. The water tank (7) and the circulating water pump (8) are arranged in sequence. The system also includes a heat exchanger (10), a refrigerant bypass pipe (11) and a hot water bypass pipe (12). The heat exchanger absorbs the running waste heat of the compressor and heats it. The circulation medium in the refrigerant and water bypass pipes. The inlet port of the refrigerant bypass pipe is switched and connected to the outlet port of the throttling device through the refrigerant reversing valve (5). The outlet port of the refrigerant bypass pipe is connected to the inlet port of the outdoor heat exchanger. The inlet end of the water bypass connecting pipe is switched and connected to the outlet end of the circulating water pump through the hot water reversing valve (6), and the outlet end of the hot water bypass connecting pipe is connected to the inlet end of the hot water heat exchanger. The heat pump system of the invention can utilize the running waste heat of the compressor to defrost and preheat hot water, and more fully utilize the running waste heat of the compressor.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a heat pump system of a heat pump water heater. Background technique [0002] Heat pump water heaters will experience frost during winter use. For the defrosting method of the heat pump, no matter it is a direct heating water heater or a circulating water heater, it generally adopts a four-way reversing valve to change direction, or adopts a hot gas bypass method, that is, when entering the defrosting process, through the " The "hot gas bypass" mode directs the high-temperature and high-pressure refrigerant discharged from the compressor directly into the evaporator for defrosting. These methods will have a certain impact on the generation of hot water during the defrosting process or the problem of poor defrosting effect, and at the same time, the user's comfort experience of using hot water will have a certain impact. [0003] In addition, a heat pump sys...
