METHOD FOR TESTING THE TIGHTNESS OF AIR CONDITIONERS IN MOTOR VEHICLES

摘要

The invention relates to a method for testing the tightness of refrigerating machines, particularly air conditioners in motor vehicles, according to which the apparatus that is to be tested is impinged upon by a gas at excess pressure. The aim of the invention is to create a method which detects all leaks, the size of which has an impact on the environment and health, while requiring substantially less effort to be implemented. Said aim is achieved by separating the adapters (7; 8) of a filling and measuring device from the air conditioner following the first test, connecting the adapters (7; 8) of a second measuring device to the air conditioner after an extended period of time, and comparing the test results thereof with the results of the first test, whereupon the air conditioner is deaerated and separated from the adapters (7; 8) of the second measuring device.
