Abstract: The compressor (18) is connected with the inner heat exchanger (7) across a refrigeration circuit. Compressed refrigerant is circulated between the compressor (18) and the heat exchange (7) with a variable output. An adjusting unit adjusts the amount of air blown by the fan (6). A computer unit ensures that the power needed for the air conditioning system does not adversely affect the power needed to drive the vehicle, and the control of the compressor is carried out to ensure a stable and comfortable control of the vehicle air conditioning.

Abstract: PROBLEM TO BE SOLVED: To correctly diagnose any leakage of refrigerant without being restricted by the operating state of a vehicle air-conditioner.SOLUTION: When the operating state of the vehicle air-conditioner is stable, a refrigerant leakage determination threshold Th is set on the basis of the outlet pressure Pd and the inlet pressure Ps of a compressor, and on the other hand, the volume flow rate Gr in a refrigerant pipe, through which a liquid refrigerant flows and which leads from a condenser to an expansion valve, is detected. When the volume flow rate Gr is determined to exceed the refrigerant leakage determination threshold Th, the diagnosis result (warning), indicating that the refrigerant is leaking, is output.
