PROBLEM TO BE SOLVED: To reduce power for driving a compressor 31 even if a manual outdoor air mode is executed.SOLUTION: An air-conditioning control device 50 controls an indoor/outdoor air switching door 23 via an electric actuator 62 to set an outdoor air introduction rate to nearly 50% if a manual outdoor air mode is executed and a detected temperature by an outdoor sensor 52 is determined to be equal to or higher than a first outdoor temperature. By so controlling, if the detected temperature by the outdoor air sensor 52 is equal to or higher than the first outdoor air temperature while the manual outdoor air mode is executed, indoor air and outdoor air can be introduced into an air conditioning case 11 nearly fifty-fifty. Owing to this, a heating value of heat absorbed from the air by an evaporator 13 can be reduced. It is, therefore, possible to reduce a load of a compressor 31 necessary to circulate refrigerant. |
