ABSTRACT:
During the period of deceleration of a vehicle, an air conditioning control unit modifies a target cooling temperature (TEO) of an evaporator to a temperature lower than that before the deceleration by γ ° C. in order to store cold in the evaporator (step S130). When the vehicle comes to rest, the air conditioning control unit sets an upwardly-modified target temperature TEOK, which is a temperature modified toward more or less higher temperatures from the target cooling temperature TEO, and brings a compressor to rest and keeps the resting state of the compressor until a detected temperature TE of an evaporator discharge temperature sensor exceeds TEOK (step S180). Therefore, it is possible to effectively utilize the cold heat stored in the evaporator6during the period of deceleration of the vehicle with a good feeling of passengers being maintained while the vehicle is at rest.
