Claims

[Scope of utility model registration request]

A variable capacity compressor using an engine as a driving source, a capacity changing means for changing the capacity of the variable capacity compressor, a clutch means for coupling and disconnecting the variable capacity compressor with the engine, and a clutch means for starting and accelerating the vehicle. a detection means for detecting the start or acceleration of the vehicle; and when the detection means detects the start or acceleration of the vehicle, the clutch means is controlled to release the connection between the variable capacity compressor and the engine, and the capacity change means is controlled to control the variable capacity compressor. a first control means for minimizing the capacity of the variable displacement compressor; and a second control means for controlling the clutch means to connect the variable displacement compressor and the engine when the capacity of the variable displacement compressor is at a minimum even when the vehicle is starting or accelerating. A vehicle air conditioner comprising: a control means.
