    摘要： An air conditioner for a vehicle uses a hybrid compressor (4) including a first compression mechanism driven by a first drive source (2) and a second compression mechanism driven by a second drive source (5), and a single discharge port connected to the first and the second compression mechanisms. The operation of the hybrid compressor is controlled by a controller (15) in accordance with a control mode. The controller has a first operation mode in which the first compression mechanism alone is driven, a second operation mode in which the second compression mechanism alone is driven, a third operation mode in which the first and the second compression mechanisms are simultaneously driven, and a fourth operation mode in which the first and the second compression mechanisms are simultaneously stopped. Depending upon various conditions, the controller selects, as the control mode, one of the first, the second, the third, and the fourth operation modes.

    摘要： An air conditioner for a vehicle comprises a refrigeration cycle including a variable displacement compressor for refrigerant which uses an engine as a drive source, a condenser, and an evaporator, a displacement adjustment means for outputting a displacement control signal to the compressor, and a compressor torque calculation means for calculating the torque of the compressor. The compressor torque calculation means includes at least two torque estimation means of a saturation region torque estimation means corresponding to a case where the compressor is driven at a maximum discharge displacement and a displacement control region torque estimation means corresponding to a case where it is driven at a discharge displacement other than the maximum discharge displacement, and also includes a correction means for correcting the calculation of the torque of the compressor when a change in engine rotational speed greater than a set value is detected. Even when the engine rotational speed changes rapidly, the torque of the compressor in the refrigeration cycle can be precisely calculated.

    摘要： In a vehicle air-conditioning device, refrigerant leakage is diagnosed precisely without any restrictions from an operating condition of the air-conditioning device. When the operating condition of the vehicle air-conditioning device is stable, a threshold value Th for determination of refrigerant leakage is set based on an outlet pressure Pd and an inlet pressure Ps of a compressor. Furthermore, a volume flow Gr in that refrigerant pipe running from a condenser to an expansion valve through which the refrigerant circulates in a liquid state is detected. When it is determined that the volume flow Gr exceeds the threshold value Th for determination of refrigerant leakage, a diagnosis result (alarm) indicating that the refrigerant leaks is output.
