Abstract

The invention discloses refrigerant recovery method and device of an air conditioner, wherein the method comprises the following steps that in the refrigerant recovery mode of the air conditioner, the air conditioner is controlled to carry out refrigeration; when the air conditioner carries out refrigeration, a refrigerant is stored in a condenser of an outdoor unit of the air conditioner after being absorbed from an evaporator of an indoor unit of the air conditioner and a connecting tube through a compressor of the air conditioner, wherein the evaporator is arranged at the air absorption end of the compressor, and the condenser is arranged at the exhaust end of the compressor; and an electronic expansion valve is controlled to close, wherein the electronic expansion valve is arranged on a connecting pipeline between the condenser and the evaporator. The refrigerant recovery method and device solve the technical problem that recovery is inaccurate caused by refrigerant recovery of the air conditioner by manual operation.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a refrigerant recovery method and device for an air conditioner. Background technique [0002] At present, most split-type air-conditioning products use manual operation when recycling refrigerant. According to experience, the staff manually closes the valves when the air-conditioning unit is running. This operation requires the staff to have rich experience, and the recovery is not necessarily accurate, and there is a certain risk of operation. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a method and device for recovering refrigerant from an air conditioner to at least solve the technical problem of inaccurate recovery due to manual operation of the recovery of refrigerant from the air conditioner. [0005] According to an aspect of an embodiment of the present in...
