Abstract
Due to the global warming effect of R-134a emissions, regulations will be issued to lower the current emission level of Mobil Air Conditioning (MAC) systems. In order to develop very low emission components, it is necessary to have accurate measurement apparatus both for components and for the complete AC system.
The paper presents the method of test, the testing equipment, and the test results of several AC systems installed in a “mini-shed”, which is at atmospheric pressure, completely tight and where the raise of concentration of R-134a is measured by infra red spectrophotometry. The tests are performed in standstill mode for different temperatures. The results are the emissions as a function of the saturating R-134a pressure for different temperatures. A new evolution of the test bench is being prepared in order to measure emissions when the MAC system is running along different driving and temperature conditions.
