Leak flow rate measurement of mobile air-conditioning components working with CO2.

Author(s) : CLODIC D., YU Y.

Summary

The Center for Energy and Processes-Paris (CEP) started to develop test benches for the measurements of refrigerant leak flow rates several years ago. For the last three years, the laboratory has been measuring CO2 (R-744) leak flow rates from various components: fittings, hoses, valves, and compressors. The measurement apparatuses are based either on infrared spectrophotometry or infrared photoacoustic spectroscopy. The paper presents the variation of emissions as a function of both pressure and temperature. From those measurements, emission laws can be elaborated.
