Claims

[Scope of utility model registration request]

A variable displacement compressor is configured to automatically perform capacity control based on an internal signal so that the suction pressure reaches a set value, and to control the set value based on an external signal, and is set to standard operation mode. a first switch to set it to the economical operation mode, a third switch to set it to the dehumidification power improvement operation mode.
and the suction pressure of the variable displacement compressor in response to a signal obtained based on a detection signal of a factor required for temperature adjustment when the standard operation mode is set by the first switch. At the same time, the second switch controls the suction pressure of the variable displacement compressor to a higher pressure than when the standard operation mode is set, and the third switch controls the dehumidifying power. 1. A control device for a vehicle air conditioner, comprising: control means for controlling the suction pressure of the variable capacity compressor to be lower than that when the standard operation mode is set when the improved operation mode is set.
