AIR-CONDITIONER FOR VEHICLE

PROBLEM TO BE SOLVED: To provide an air-conditioner for a vehicle to perform an air-conditioning control capable of improving the comfortableness to solar insolation at a low angle of elevation difficult to detect. SOLUTION: An air-conditioning ECU 8 of this vehicle air-conditioner according to the embodiment of the invention conducts a solar insolation correction in which a solar insolation amount having a larger value than the actually sensed solar insolation amount is used to the air-conditioning control in case the outer air temperature sensed by an outer air temperature sensor 81 is lower than the prescribed level and the solar insolation amount sensed by a solar insolation sensor 83 is smaller than the prescribed amount. By this control, a proper correction can be applied to the solar insolation of a low angle of elevation difficult to be sensed, and when the angle of elevation is large, it is possible to prevent the occupant's comfortableness from being impaired as no excessive solar beam amount correction takes place when the angle of solar insolation elevation is large. In particular in the winter period, both in the morning and evening and in the daytime, a well-balanced air-conditioning as not offering excessive heating or cooling to the occupant can be conducted.
