Abstract
An automobile air conditioning system has a bypass air passage for directing air, before it is heated, to a car interior via a vent outlet. A bypass door is disposed in the bypass air passage, which has an opening which is automatically controlled according to a desired air conditioning temperature in an automatic air conditioning mode. The bypass door control can be intentionally changed to a mild control mode, in which the opening of the bypass door is automatically controlled to become smaller as the temperature of air, which either is in the bypass passage or is to be introduced into the bypass passage, becomes lower in a predetermined range of temperatures.
