PURPOSE:To aim at making automatic air-condition comfortable, by changing over the operation mode of an air-conditioning device into a mode controlled by an automatic control means if a manual control condition is deviated from an optimum control condition during start of the air-conditioning device. CONSTITUTION:A control unit 29 receives a passenger's compartment temperature signal from a passenger's compartment temperature sensor 30, an outside air temperature signal from an outside air temperature sensor 31, a duct-inside temperature signal from a duct temperature sensor 32, a cooling water temperature signal from a water temperature sensor 33 and solar radiation signals from first and second solar radiation sensors 35, 37. Further, there is provided a manipulation switch 38 for manual control 38. During start of the air- conditioning device, when an already selected control condition for manual control is deviated from an optimum control condition which would be established if an automatic control mode is selected, the manual control mode is changed over into the automatic control mode so that the control operation is suitable for the present environment under the automatic control mode, thereby it is possible to obtain a comfortable air-condition. |
