Abstract
In a refrigerant cycle for a vehicle air conditioner, a compressor is operated by a power from a vehicle engine, a load detecting unit is disposed to detect load of the engine, an electromagnetic clutch is turned off so that a consumed power consumed in the compressor is reduced to zero when the load detected by the load detecting unit is equal to or larger than a first threshold value. In the refrigerant cycle, the first threshold value is set to be changed along a power-cutting curved line in such a manner that an increase rate of the first threshold value relative to the vehicle speed becomes larger as the vehicle speed becomes larger.
