Abstract
An air conditioning apparatus for the cabin of a vehicle wherein an increased amount and/or temperature of an air flow from an upper outlet is obtained when sun radiation is introduced into the cabin. A provisional air flow correction amount DVA1 is calculated based on a detected sun radiation amount. A final air flow correction amount DVA is calculated as the provisional air flow correction amount DVA1 multiplied by a sun radiation correction factor GUN, the value of which is varied from 1.0 to 0 as the increase in a value of a required discharged air temperature TAOB in a range of the temperature TAOB higher than 50.degree. C. The amount of sun radiation, which makes an upper level discharged air temperature to be equal to 20.degree. C., is increased in accordance with the increase in the required discharged air temperature TAOB at the region of the temperature TAOB higher than 50.degree. C. As a result, during the winter season, an increase in the air flow amount and the discharged air temperature for cancelling the sun radiation is suppressed, thereby preventing a driver and a passenger from feeling cold.
