Abstract:
A vehicle air-conditioning system which has a compressor for compressing refrigerant and an evaporator mounted inside an air-conditioner casing, said casing forming a passage to channel air into a vehicle interior, the air being cooled by evaporation of refrigerant in the evaporator, the vehicle air-conditioning system comprising:first clock means for measuring a time from an operation of the compressor being stopped; second clock means for measuring a time from an operation of the compressor being started; and means for executing an intermittent operation mode after the operation of the compressor is stopped, the compressor being intermittently operated by stopping the compressor until the time measured by the first clock means reaches a first predetermined time, and thereafter operating the compressor until the time measured by the second clock means reaches a second predetermined time which is shorter than the first predetermined time; wherein the intermittent operation mode is stopped when a temperature of air passing through the evaporator has exceeded a wet-bulb temperature of the evaporator.
