ABSTRACT:
In a blowout temperature control system of an air conditioner for use in vehicles, a temperature detected by a ventilation duct sensor is weighted by a first weighting ratio which varies depending on a wind amount of a ventilation duct. A temperature detected by a defroster duct sensor is weighted by a second weighting ratio which is determined by the first weighting ratio. The weighted mean is calculated from the weighted detection temperatures of the ventilation duct and defroster duct, so that a substantial blowout temperature is determined. A deviation temperature between the substantial blowout temperature and an object blowout temperature is calculated and the blowout control is performed such that the deviation temperature becomes zero.
