Low-temperature intelligent triple heat supply pump unit

Abstract

The invention relates to a low-temperature intelligent triple heat supply pump unit. The low-temperature intelligent triple heat supply pump unit comprises a compressor, heat exchangers, a gas separation device and various valve bodies. The heat exchangers include an outdoor heat exchanger, an economizer heat exchanger, an air conditioner heat exchanger and a hot water heat exchanger. The output end of the compressor is connected with an electromagnetic valve a and an electromagnetic valve b in parallel. The electromagnetic valve a is connected with an inlet D of a four-way electromagnetic valve. The output end of a connector C of the four-way electromagnetic valve is sequentially connected with the outdoor heat exchanger, an electronic expansion valve c and a liquid storage device. The output end of a connector S of the four-way electromagnetic valve is connected with the first input end of the compressor through the gas separation device. The output end of a connector E of the four-way electromagnetic valve is connected with the air conditioner heat exchanger through an electromagnetic valve c. The electromagnetic valve b is connected with the hot water heat exchanger. The output end of the hot water heat exchanger is connected with the economizer heat exchanger and the air conditioner heat exchanger through a check valve a. The low-temperature intelligent triple heat supply pump unit has the advantages that the unit is provided with a few elements, is multifunctional and guarantees the heating effect in a low-temperature environment, and a pipeline is simple.

Description

technical field [0001] The invention relates to a heat pump unit, in particular to a low-temperature intelligent triple heat pump unit. Background technique [0002] At present, most air source heat pumps on the market operate at a temperature range of -7 to 43°C. And when the temperature is lower than 0°C, the heating capacity will be seriously attenuated, which will affect the user experience. Especially in northern my country, the temperature in winter is generally below 0°C, and conventional air source heat pumps cannot work normally. Therefore, heating in winter in northern China is mostly based on heating. Its use will be gradually limited, so it is necessary to develop an air source triple supply system that can operate normally at low temperatures. [0003] Chinese Patent Publication No. CN203396002U, the publication date is January 15, 2014. The name of the invention is an ultra-low temperature triple heat pump unit. The application specifically discloses an ultra-...
