Abstract

The invention relates to a refrigerant recovery control method, device and air conditioner, belonging to the field of intelligent control of air conditioners. The refrigerant recovery control method includes the following steps: receiving a refrigerant recovery instruction; controlling the air conditioner to close the expansion valve after the refrigeration operation for a first preset time to recover the refrigerant; Open the expansion valve to return the air conditioner to cooling operation. The refrigerant recovery control device is used to control the air conditioner to implement the aforementioned refrigerant recovery control method. The air conditioner and the corresponding refrigerant recovery control method and device can close the expansion valve after a certain period of refrigeration operation after receiving the refrigerant recovery instruction input by the relevant operator, so as to realize automatic recovery of the refrigerant, and the operation is simple and convenient. Moreover, the air conditioner can also effectively correct misoperations of relevant operators, so as to avoid its own failure and ensure its normal operation.

Description

technical field [0001] The invention relates to the field of intelligent control of air conditioners, in particular to a refrigerant recovery control method, a refrigerant recovery control device and an air conditioner. Background technique [0002] During the use of the air conditioner, it needs to be disassembled and assembled when encountering situations such as moving. Before disassembling the machine, the refrigerant needs to be recovered. Before recycling the refrigerant, the air conditioner needs to be turned on to the cooling mode, and the liquid outlet pipe (small shut-off valve) of the air conditioner’s external unit must be manually closed with a tool, and the return pipe (large shut-off valve) should be closed after the compressor has been running for a period of time for refrigerant recovery. [0003] However, the current refrigerant recovery method has the problem of cumbersome and inconvenient operation because two manual operations are required. Contents ...
