摘要

The vehicle air conditioning system comprises a cooler (6), a coolant circulation circuit (1) comprising a coolant compressor (2) and a radiator (8) for reheating the air drawn into the vehicle interior. There is a means for determining the deceleration in order to determine if a vehicle is decelerating, and a stop mechanism (14,15) for stopping engine cooling water flow which flows to and from the radiator, when it is determined that the vehicle is decelerating. The stop mechanism operates in order to the stop the flow of engine cooling water and the storage of the cold or heat is carried out in the radiator by passing air through the radiator after it has passed through the cooler.
