Fahrzeug-Klimaanlage

摘要

An air conditioning apparatus for the cabin of a vehicle wherein an increased amount and/or reduced temperature of an air flow from an upper outlet 21 is obtained when sun radiation is introduced into the cabin. A provisional air flow correction amount DVA1 is calculated based on detected sun radiation. 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 a required discharged air temperature TAOB increases in a range higher than 50 DEG C. The amount of sun radiation, which makes an upper level discharged air temperature to be equal to 20 DEG 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 DEG C. As a result, during the winter an increase in the air flow for cancelling the sun radiation is suppressed, thereby preventing a driver and passenger from feeling cold. <IMAGE>
