PURPOSE:To prevent air within a car room from being contaminated while an air conditioner is controlled for introduction of inside and outside air by controlling the car air conditioner such that it is brought into an inside air introduction condition when requirement for inside air is produced and is periodically changed over into a temporary outside air introduction condition. CONSTITUTION:A duct 1 of a car air conditioner has housed therein a blower 2, an inside and outside air change-over damper 6, an evaporator 7, a heater 8, an air mix damper 9 and so on. The dampers 6, 9 and the blower 2 are controlled by a microcomputer 15 each in accordance with an air conditioner controlling program containing an inside and outside air controlling program therein. If an inside and outside switch 14 is operated to the inside air side, the microcomputer 15 effects a changing over control of the damper such that outside air is temporarily taken in at a different ratio of time in accordance with set values by a blowing out wind setting means 12 and a blowing out wind temperature setting means 11. Thus, for example, introduction of outside air is performed for a period of time of 3min after circulation of inside air for a period of time of 7min. |
