    Abstract: A vehicle air conditioner includes a compressor and variable-volume compressor in a freezing cycle, means for operating the variable-volume compressor, compressor operation switching means for switching the operation of the compressor and the variable-volume compressor, and variable-volume compressor feed forward volume value calculation means for calculating a volume control value of the variable-volume compressor as an input to the freezing cycle so as to obtain a target control volume after the compressor operation is switched. After the operation is switched from the compressor to the variable-volume compressor, the variable-volume compressor is started according to the variable-volume compressor feed forward volume value calculated. When the coolant flow amount of the freezing cycle is greatly changed upon operation switching between the compressor and the variable-volume compressor, it is possible to suppress deterioration of the pleasant feeling of passengers.

    Abstract: 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.
