Abstract
An air conditioner for a vehicle uses a hybrid compressor ( ) including a first compression mechanism driven by a first drive source ( ) and a second compression mechanism driven by a second drive source ( ), 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 ( ) 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.
