VEHICULAR AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide a vehicular air conditioner suppressing generation of odor even in a device accompanying with switching of internal/external air and attaining enhancement of fuel consumption of the vehicle.

SOLUTION: The vehicular air conditioner is provided with an internal/external air switching means 14 for forming a switching mode for selecting/switching at least one of in-cabin air and out-cabin air as suction air and taking-in the selected/switched air into an air-conditioning case 10; and an evaporator 9 for cooling the suction air taken-in into the air-conditioning case 10. A dew point temperature of the suction air exceeds an evaporator temperature of the evaporator 9 and thereafter when the dew point temperature is less than the evaporator temperature, a control means 5 for changing the switching mode is provided relative to the internal/external air switching means 14 such that the dew point temperature becomes the evaporator temperature or higher.
