ABSTRACT:
An air conditioning system having an evaporator 8 at a location upstream from a compressor. When a compressor is stopped, a refrigerant inlet is closed by an electromagnetic valve 28 and a refrigerant outlet is closed by a check valve 29. A pressure in the closed passageway is detected by a pressure sensor 22. A leakage of refrigerant at the evaporator is reliably detected, which allows the leakage of the refrigerant to be quickly noticed.
