Title:
AIR CONDITIONER FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/002546
Kind Code:
A1
Abstract:
Provided is an air conditioner for a vehicle such that the reliability of the air conditioner is increased by precisely safeguarding decompression. On the basis of a detected value of an intake temperature sensor and a limit target value TGTs that is set relative to the intake coolant temperature of a compressor 2, a controller regulates a rotational speed Nc of the compressor 2 such that the detected value does not fall below the limit target value TGTs. When the compressor 2 starts, the controller, which has a predetermined limit lower-bound value TGTsL and a predetermined limit upper-bound value TGTsH that is higher than the value TGTsL, regulates the rotational speed Nc of the compressor 2 with the limit upper-bound value TGTsH as the limit target value TGTs, and if the detected value drops below the limit upper-bound value TGTsH, the limit target value TGTs is gradually reduced to the limit lower-bound value TGTsL.
