Title:
AIR-CONDITIONING DEVICE FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2018/225486
Kind Code:
A1
Abstract:
Provided is an air-conditioning device for vehicles which is capable of eliminating the inconvenience of a compression malfunction occurring upon a compressor starting up when outside air temperature is low. The air-conditioning device for vehicles is provided with a compressor 2 and a control device 11 for controlling the rotation speed of the compressor 2 so as to be at a prescribed target rotation speed. An air-conditioning controller 20 of the control device 11 is provided with an outside air temperature sensor 33 for detecting the outside air temperature. In the event that the outside air temperature is no higher than a prescribed value at the time of the compressor 2 starting up, a heat pump controller 32 of the control device 11 executes control restricting the lower limit of the compressor rotation speed such that the target rotation speed of the compressor 2 is set to at least a prescribed lower rotation-speed limit A1.
