Problems solved by technology

[0002] R22 and R410A are commonly used refrigerants (that is, refrigerants) in multi-air conditioners. These refrigerants are safe, non-toxic, and non-flammable. Potential safety hazards, China and many other countries have expressly stipulated that the concentration limit of room refrigerant escape in case of leakage is 0.4kg / m3
[0003] In addition, once the refrigerant in the air conditioner leaks, if it is not found in time, it will not only cause a sharp decline in the cooling and heating efficiency of the air conditioner, but also seriously affect or even damage the compressor, increasing the maintenance rate of the compressor.

Abstract

The invention provides a refrigerant leak detection method and device and an air conditioner. The refrigerant leak detection method includes the steps that the real-time gas exhaust temperature of a compressor of the air conditioner is detected; according to the work condition and the running state of the air conditioner, the theoretical gas exhaust temperature of the compressor is determined; and according to the real-time gas exhaust temperature and the theoretical gas exhaust temperature, whether refrigerants in the air conditioner leak or not is determined. By means of the technical scheme, whether the refrigerants in the air conditioner leak or not can be detected, and harm to the air conditioner and potential safety hazards brought to users because of refrigerant leakage are avoided as far as possible.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a refrigerant leakage detection method, a refrigerant leakage detection device and an air conditioner. Background technique [0002] R22 and R410A are commonly used refrigerants (that is, refrigerants) in multi-air conditioners. These refrigerants are safe, non-toxic, and non-flammable. Potential safety hazards. In this regard, China and many other countries have expressly stipulated that the concentration limit of room refrigerant escape in case of leakage is 0.4kg / m3. [0003] In addition, once the refrigerant in the air conditioner leaks, if it is not found in time, it will not only cause a sharp decline in the cooling and heating efficiency of the air conditioner, but also seriously affect or even damage the compressor, increasing the maintenance rate of the compressor. [0004] Therefore, how to intelligently detect whether the refrigerant in the air condit...
