UNEXPECTED TORQUE CALCULATING METHOD FOR LIQUID REFRIGERANT CONTAING COMPRESSOR AND VEHICLE AIR CONDITIONER INCLUDING CONTROLLER IMPLEMENTING THE METHOD

摘要

The present invention relates to a method for calculating an anticipated torque of a compressor including a liquid refrigerant and a vehicle air conditioner including a controller for performing the method.(A) a step (S110) in which, after the vehicle air conditioner is operated, the refrigerant existing inside the compressor is regarded as a gas and an expected torque of the compressor is calculated; (B) calculating a correction torque based on the engine coolant temperature detected by the sensor (S120); And (C) a step (S130) in which the corrected torque is applied to the estimated torque to calculate a final estimated torque of the compressor. At this time, the correction torque becomes smaller as the detected engine cooling water temperature becomes higher. After the detected engine cooling water temperature reaches the target temperature which is the engine cooling water temperature at the time when the phase change of the liquid refrigerant is completed, M. /RTI ;
