Abstract

The invention discloses a refrigerant adjusting method, and device and an air conditioner. The method comprises the following steps: acquiring a present refrigerant mass flow rate; comparing the present refrigerant mass flow rate with a standard refrigerant mass flow rate; adjusting a refrigerant mass flow rate output by a refrigerant liquid storage according to a comparison result of the present refrigerant mass flow rate and the standard refrigerant mass flow rate. According to the invention, through the comparison of the present refrigerant mass flow rate and the standard refrigerant mass flow rate, if the refrigerant charge is suitable or not can be automatically judged and the refrigerant charge can be automatically adjusted under a condition of a long connecting pipe, and refrigerant does not need to be additionally added through manpower, so that the inconvenience in additionally adding the refrigerant on engineering installation is eliminated and the increasing of additional cost brought by adding the refrigerant is eliminated.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a refrigerant regulating method, device and air conditioner. Background technique [0002] The amount of air-conditioning refrigerant filling is generally determined through experiments under the standard connecting pipes required by the exporting country, and is filled according to this refrigerant filling amount before leaving the factory. [0003] In practice, due to different installation occasions, the connecting pipe used by the user is not a standard connecting pipe, generally a long connecting pipe. In this case, the current common practice is to add refrigerant according to the length of the connecting pipe. This not only brings inconvenience to the engineering installation, but also increases the workload. At the same time, additional refrigerant may also bring additional cost increase. Contents of the invention [0004] In view of the above technical problems, the pr...
