Abstract

The invention belongs to the field of air conditioners and particularly relates to an air conditioning system and a monitoring method and device of refrigerant leakage of the air conditioning system. In the operation process of the air conditioning system, real-time operation frequency Fr1 and real-time exhaust temperate Tp of a compressor are compared with a preset maximum frequency value Fr and a preset temperature protection threshold Tmax which correspond to real-time outdoor environment temperate, when Fr1 is smaller than Fr-N and Tp is larger than Tmax, it is judged that refrigerant may leak, whether refrigerant leakage of the air conditioning system happens or not can be monitored in advance in real time, and under the condition that it is judged that the refrigerant may leak, the refrigerant leakage detection confirmation step preferentially and automatically starts, so that little leakage of a small amount of refrigerant can be conveniently and effectively detected in time, and the adverse consequence that the effect of the air conditioning system becomes poor due to further leakage of the refrigerant, and accordingly user experience is affected is avoided.

Description

technical field [0001] The invention belongs to the field of air conditioning, and in particular relates to an air conditioning system and a method and device for monitoring refrigerant leakage thereof. Background technique [0002] For air conditioner users, when using the air conditioner, it is likely to encounter the problem of poor cooling or heating effect of the air conditioner, and the cause of this problem is often the leakage of refrigerant. Generally, the internal and external units of split-type household air conditioners need to be installed and connected on-site at the user's home. The connection ports of the internal and external units are prone to instability, or during the long-term operation and vibration of the air conditioner, other copper pipes are vulnerable. A refrigerant leak may occur. In the air-conditioning system, the leakage of refrigerant will reduce the amount of refrigerant inhaled by the compressor, resulting in the reduction of the heat gene...
