Title:
CONTROL DEVICE FOR VEHICULAR AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3134705
Kind Code:
B2
Abstract:
PURPOSE: To prevent the blow-off of cold air at the beginning of heating operation and improve the startup of heating operation in a heat pump type air conditioner.
CONSTITUTION: When the detected temperature Tw of a water temperature sensor 106 for detecting the temperature of a heater core 22 is the reference temperature T1 or lower, blasting by a blower 3 is stopped, and the rotating speed of a refrigerant compressor 11 is controlled to the maximum rotating speed. Upon reaching the reference temperature T1 or higher, blasting by the blower 3 is started, and the rotating speed of the refrigerant compressor 11 is controlled according to the target blow-off temperature. Since the air is not blasted while the temperature of the discharge side high-pressure refrigerant of the refrigerant compressor 2 is low and the temperature of hot water in a hot water circuit 20 is low, the cold air is not blown off into a cabin. At this time, the refrigerant compressor 11 is controlled to the maximum rotating speed, so that the temperature of high pressure refrigerant becomes high, and the hot water temperature of the hot water circuit 20 rises rapidly so as to shorten the time until the start of blowing off.
