Title:
AIR CONDITIONER FOR VEHICLE
Document Type and Number:
Japanese Patent JP2003002044
Kind Code:
A
Abstract:

To prevent discharge pressure and a discharge temperature of a compressor from increasing when air capacity of an external heat exchanger becomes small in vehicular stop.

As a temperature of a refrigerant circulating in a refrigerating cycle comprising a compressor 1, a heat-exchanger 2 outside a cabin, a restriction device 3, a heat-exchanger 4 inside the cabin, the discharge temperature of the compressor is detected by a temperature sensor 5. When stopping the vehicle, if the discharge temperature of the compressor becomes higher than a first set value, the number of revolutions of a fan 6 outside the cabin is increased, and if the discharge temperature of the compressor becomes even higher than a second set value, the number of revolutions of an electric motor for driving a compressor 1 is decreased by means of instructions from a compressor control apparatus 18.
