ABSTRACT:
An air conditioner system for an automotive vehicle includes air cooling means, air heating means arranged downstream of the air cooling means, a bypass air passage bypassing the air heating means, means for detecting the temperature of intake air immediately before passing through the air cooling means, and means for comparing the intake air temperature detected by the intake air temperature detecting means and a desired temperature. The amount of air flow through the bypass air passage is controlled when the intake air temperature is lower than the desired temperature by a first predetermined deviation value, and the amount of air flow through the bypass air passage is controlled at the maximum value when the intake air temperature is greater than the desired temperature value by a second predetermined deviation value. The compressor is actuated when the intake air temperature is larger than the desired air temperature. The compressor is not actuated when the intake air temperature is smaller than the desired air temperature.
