VEHICULAR AIR CONDITIONER

PROBLEM TO BE SOLVED: To reconcile window uncloudiness at dehumidifying/heating time and security of heating performance by arranging an intake opening adjusting means for adjusting an outside air introducing rate by an intake device so as to converge an air temperature on a target air temperature. SOLUTION: A window glass inside surface temperature is arithmetically operated from input signals from respective sensors to arithmetically operate a temperature just after target evaporation required for window uncloudiness from this arithmetically operated window glass inside surface temperature (Step 52). Afterwards, a difference ΔT between a target temperature and a measured temperature is arithmetically operated (Step 54), and when this difference falls within a range of ±1 deg.C, a change in intake opening is obviated. While, since there is the possibility of inducing cloudiness of window glass when the ΔT is larger than -1 deg.C, the intake opening is moved to the outside air intoducing side to converge the measured temperature on the target temperature. When the ΔT is larger than +1 deg.C the intake opening is moved to the inside air introducing side to enhance heating performance to converge the measured temperature on the target temperature (Step 56).
