Abstract

The invention provides a device and a method for detecting leakage of a refrigerant of an automobile air conditioning system and particularly relates to a device for detecting leakage of the refrigerant of the automobile air conditioning system. The system comprises an environment cabin, a temperature control system used for controlling the temperature of the environment cabin, a gas balance device used for controlling gas balance in the environment cabin, and a refrigerant analysis device used for the environment cabin, wherein the temperature control system is installed in the environment cabin, the environment cabin is provided with a gas inlet, the gas balancing device is connected with the gas inlet, the environment cabin is provided with a sampling port and a sample return port, one end of the refrigerant analysis device is connected with the sampling port, and the other end of the refrigerant analysis device is connected with the sample return port. According to the refrigerant leakage detection device, the leakage rate of the whole air conditioner system can be comprehensively and scientifically analyzed, and enterprises can explore and rectify the leakage level of the automobile air conditioner.

Description

technical field [0001] The invention belongs to the technical field of automobile air-conditioning testing, and in particular relates to a device and method for detecting refrigerant leakage of an automobile air-conditioning system. Background technique [0002] At present, the air-conditioning system has become an important part of the car. Due to the design, material selection, and assembly differences in the R&D and production stages of the air-conditioning system, the refrigerant will leak to different degrees through the interface, hoses and other parts during operation, making the air-conditioning system. Cooling and heating performance is reduced. Moreover, automotive air-conditioning refrigerants have high global warming potential (GWP), and the leakage of automotive air-conditioning refrigerants will aggravate global warming. It is necessary to evaluate the leakage rate of the air-conditioning system during the operation stage during the R&D design stage, and take ...
