Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] A specific embodiment of the present application provides an air source heat pump system, which is used to store heat energy in outdoor low-temperature air to heat an indoor environment. Specifically, the air source heat pump system includes an indoor heat exchanger, an outdoor heat exchanger, a pipeline connecting the indoor heat exchanger and the outdoor heat exchanger, a throttling valve installed in the pipeline, and two realizations installed in the pipeline Refrigerant compressor. When the air source heat pump system is working, the compressor compresses the high-temperature refrigerant and supplies it to the indoor heat exchanger. After the indoor heat exchanger cools down, the compressed refrigerant flows into the outdoor heat exchanger controlled by the throttle valve and evaporates in the outdoor heat exchanger. Absorb heat a...

Abstract

The invention provides an air source heat pump system. The air source heat pump system comprises an outdoor heat exchanger and an air volume adjusting assembly; when the air source heat pump system isin a normal heating working state, the air volume adjusting assembly is in a first state so that airflow is enabled to flow through the surface of the outdoor heat exchanger; and when the air sourceheat pump system is in a defrosting working state, the air volume adjusting assembly is in a second state to prevent the airflow from flowing through the surface of the heat exchanger. When the air source is in the defrosting state, a windshield assembly is in a second working state, so that too fast convection and the heat exchange of the outdoor heat exchanger and a surrounding environment is avoided, then heat energy loss of the outdoor heat exchanger in the defrosting process is reduced, and the utilization efficiency of the heat energy is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration and heating, in particular to an air source heat pump system. Background technique [0002] The air source heat pump system is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. As an efficient and clean new energy utilization technology, the air source heat pump system has been used as a winter heating system and has begun to be applied in high latitude regions. [0003] The air source heat pump system includes a compressor, a throttle valve, an indoor heat exchanger, an outdoor heat exchanger and pipelines connecting the aforementioned components. When the air source heat pump system is working, the outdoor heat exchanger acts as an evaporator for evaporating the refrigerant and absorbing heat. [0004] When the temperature of the outdoor heat exchanger is lower than the dew point temperature of the air and the ...
