Abstract

The invention discloses a heat pump unit. The heat pump unit comprises an indoor unit and an outdoor unit. The indoor unit comprises an indoor unit shell and indoor air conditioner system parts located in the indoor unit shell. The outdoor unit comprises an outdoor unit shell and an outdoor air conditioner system part located in the outdoor unit shell. The indoor air conditioner system parts and the outdoor air conditioner system part are connected through a refrigerant pipeline to form a refrigerant loop of the heat pump unit. The indoor air conditioner system parts include a compressor and a water side heat exchanger used for condensing refrigerants when the heat pump unit is used for conducting heating. The outdoor air conditioner system part includes an air cooling heat exchanger used for evaporating the refrigerants when the heat pump unit is used for conducting heating. The heat pump unit can solve the problem that the water side heat exchanger and water way valve pieces are prone to freezing when the heat pump unit is at a low temperature.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to a heat pump unit. Background technique [0002] In the prior art, heat pump units involving waterway heat exchange are all integral heat pump units. The integral heat pump unit uses the compressor, the water side heat exchanger used to condense the refrigerant when the heat pump unit is heating, and the air-cooled heat exchanger (usually a fin heat exchanger) used to evaporate the refrigerant when the heat pump unit is heating. , gas-liquid separator, four-way valve, expansion valve, etc. are all arranged in a shell, and the shell together with its internal air conditioning system components are placed in the outdoor environment. [0003] There are two major defects in the integral heat pump unit: one is that the integral heat pump unit has the problem that the waterway is easy to freeze at low temperature, and it is easy to cause the components of the water-side heat e...
