Abstract

The invention discloses an air-conditioning system. The air-conditioning system comprises a compressor, a four-way valve, an indoor heat exchanger, an outdoor heat exchanger, a control valve and a throttling control assembly. The first end of the four-way valve is connected with the second end of the four-way valve through the outdoor heat exchanger, the throttling control assembly, the indoor heat exchanger and the control valve in sequence. The third end of the four-way valve is connected with an exhaust outlet of the compressor. The fourth end of the four-way valve is connected with an air return opening of the compressor. The throttling control assembly is used for throttling a refrigerant flowing into the indoor heat exchanger from the outdoor heat exchanger, and meanwhile controlling the opening degree of a flow path between the outdoor heat exchanger and the indoor heat exchanger. The invention further provides an air-conditioner and a refrigerant recycling control method. According to the air-conditioning system, the air-conditioner and the refrigerant recycling control method, when the refrigerant is recycled, the throttling control assembly can be closed directly so as to recycle the refrigerant, the control valve is closed to achieve automatic recycling of the refrigerant when refrigerant recycling is completed, and thus the refrigerant recycling cost can be reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioning system, an air conditioner and a refrigerant recovery control method. Background technique [0002] The refrigerant is the cooling medium of the air conditioner, and the indoor heat exchanger and the outdoor heat exchanger are used to exchange heat to realize the cooling of the air conditioner. When the refrigerant flows through the air conditioning system for heat exchange, the refrigerant often remains in the pipe. affect the cooling effect. In the prior art, professionals often need to manually recover the refrigerant, and the cost of refrigerant recovery will be high. Contents of the invention [0003] The main purpose of the present invention is to provide an air conditioning system, an air conditioner and a refrigerant recovery control method, aiming at realizing the automatic recovery of refrigerant and reducing the cost of refrigerant recovery.
