Abstract

An air-conditioning control system for automotive vehicles, comprising a compressor variable in capacity in accordance with a change in suction pressure thereof. A controller is provided which carries out demisting control, on the basis of output signals from various sensors, in such a manner that, when outdoor-air temperature is equal to or lower than a predetermined value and at the same time the air-conditioning control system is in the indoor-air recirculating mode, the suction pressure set by the controller is lowered to a value at which temperature on the outlet side of an evaporator is brought to a value equal to or lower than a predetermined freezing temperature, and when a state in which freezing of the evaporator may occur has continued for a predetermined period of time, the set suction pressure of the compressor is raised until the temperature on the outlet side of the evaporator is brought to a value equal to or higher than a predetermined non-freezing temperature.
