AIR CONDITIONING SYSTEM AND METHOD FOR LEAKAGE DETECTION IN AN AIR CONDITIONING SYSTEM

There is described an air conditioning system (10) with a refrigerant circuit (11), wherein the air conditioning system (10) includes a leakage detection system (32). The leakage detection system (32) comprises a room temperature sensor (40), an inlet temperature sensor (34) for detection of a refrigerant temperature at a refrigerant inlet (16) of a refrigerant evaporator (15), and an outlet temperature sensor (36) for detection of a refrigerant temperature at a refrigerant outlet (17) of the refrigerant evaporator (15). The sensors (34, 36, 40) are coupled with a calculating unit (38). In addition, there is described a method for leakage detection, in which a room temperature of the room (18) to be air- conditioned is detected before the refrigerant evaporator (15) on an air inlet side (41), a refrigerant inlet temperature is detected at the refrigerant inlet (16) of a refrigerant evaporator (15), and a refrigerant outlet temperature is detected at a refrigerant outlet (17) of the refrigerant evaporator (15).
