Abstract

The embodiment of the invention provides a judgment method and device for air-conditioner refrigerant leakage, relates to the technical field of air-conditioners, and aims at solving the problem that whether a refrigerant is leaked or not cannot be accurately judged merely by detecting a gas exhausting temperature of a compressor. According to the technical scheme, the method comprises specifically the steps of obtaining a current work pattern, a current outdoor coil pipe temperature, and a current indoor coil pipe temperature of an air conditioner, current gas exhausting temperature and current running frequency of the compressor, obtaining a corresponding first threshold value according to the current running power, and judging whether the refrigerant in the air-conditioner is leaked or not according to the current work pattern and the difference value between first absolute difference and the first threshold value of the current air exhausting temperature and the current outdoor coil pipe temperature, or the difference value between second absolute difference and the first threshold value of the current air exhausting temperature and the indoor outdoor coil pipe temperature. The judgment method and device for air-conditioner refrigerant leakage are applicable to air-conditioners.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for judging refrigerant leakage of an air conditioner. Background technique [0002] At present, there are three common cases of air conditioner refrigerant leakage. The first is that the air conditioner itself has refrigerant leakage before the air conditioner is installed; Refrigerant leakage occurs; the third is refrigerant leakage caused by system aging during the use of the air conditioner. For air conditioner users, usually only when the cooling and heating effect of the air conditioner is not obvious, the refrigerant leakage of the air conditioner will be noticed, and often at this time, the refrigerant leakage is already serious, and it is impossible to judge when the air conditioner has refrigerant according to the current situation leakage. If the air conditioner has refrigerant leakage and the compressor is still running, the compressor o...
