Problems solved by technology

[0004] If the threshold is set too large, the detection sensitivity will decrease, that is, it may cause a lot of leaks before it can be detected. If the threshold is set too small, it will easily lead to false detection due to detection errors, and the detection accuracy will be poor.

Abstract

The invention provides an air conditioner refrigerant leakage detecting method and system and an air conditioner. The air conditioner refrigerant leakage detecting method comprises the steps of: detecting exhaust parameters of a compressor and a refrigerant mass and flow in a preset position in a refrigerating system; calculating a refrigerant mass and flow in an outlet of the compressor accordingto the calculated exhaust parameters of the compressor; and determining if refrigerants of the air conditioner are leaked according to the refrigerant mass and flow in the outlet of the compressor and the refrigerant mass and flow in the preset position. The air conditioner refrigerant leakage detecting method can simply, conveniently and accurately judge if the refrigerants of the air conditioner are leaked, so that such bad effects as performance reduction of the air conditioner and damage of the compressor caused by the refrigerant leakage are prevented, and the safety and the reliabilityof the air conditioner are improved.

Description

technical field [0001] The present application relates to the technical field of refrigeration equipment, in particular to a refrigerant leakage detection method and system for an air conditioner and an air conditioner. Background technique [0002] Leakage of the refrigerant (refrigerant) of the air conditioner not only affects the cooling and heating levels of the air conditioner, but also poses safety hazards. For example, for flammable refrigerants, if there is too much leakage, it may catch fire and pose a safety hazard. Therefore, it is necessary to detect refrigeration Whether the agent has leaked. In related technologies, it is possible to determine whether leakage occurs by detecting the concentration of the leaked refrigerant, for example, when the detected concentration reaches a specific threshold, it is determined that leakage occurs. [0003] The following technical issues exist: [0004] If the threshold is set too large, the detection sensitivity will decre...
