Abstract

The invention relates to the technical field of residential heating systems, in particular to an energy storage type air source heat pump heating system and an operating method thereof. The system includes: an air source heat pump circuit, including a phase change accumulator, a plate heat exchanger, an outdoor heat exchanger, a gas-liquid separator, a compressor whose input end communicates with the output end of the gas-liquid separator, and an outdoor heat exchange The four-way reversing valve connected to the input and output ends of the gas-liquid separator, the input end of the gas-liquid separator, and the output end of the compressor, and an expansion valve is connected in series on the pipeline connecting the four-way reversing valve and the input end of the outdoor heat exchanger. The phase change accumulator and the plate heat exchanger respectively form an on-off bypass connection with the first pipeline between the four-way reversing valve and the expansion valve; the heating circuit includes the indoor heat exchanger unit, the input end and the indoor heat exchanger The output end of the heat unit is connected, the output end is connected with the input front end of the indoor heat exchanger unit through the second pipeline, and the phase change accumulator and the plate heat exchanger respectively form an on-off bypass with the second pipeline connect.

Description

technical field [0001] The invention relates to the technical field of residential heating systems, in particular to an energy storage type air source heat pump heating system and an operating method thereof. Background technique [0002] The air source heat pump is based on the reverse Carnot cycle principle, using the ambient air as the heat (cold) source, driving the compressor with a small amount of electric energy to realize the transfer of heat energy in the ambient air, thereby producing hot (cold) wind or hot (cold) water equipment. The air source heat pump used for residential heating mainly includes a compressor, a gas-liquid separator connected in series with the compressor, and an indoor heat exchanger, an expansion valve and an outdoor heat exchanger connected in series. The compressor, the indoor heat exchanger, and the outdoor The heat exchanger and the gas-liquid separator are respectively communicated with the four ports of the four-way reversing valve to f...
