ABSTRACT:
An air-conditioning system allows adjustment of the vented air temperature of a rear seat evaporator. An electronic control system judges whether the surface of the rear seat evaporator is frosting up when 1) a target blowing rate of the rear seat blower is lower than a predetermined value, 2) a detected temperature of evaporator vented air is lower than a specified temperature TEa, and 3) a detected temperature of the outside air is lower than a specified temperature TAMa. A target temperature TEO is raised at this time, so that an electric motor of an electric compressor is stopped and refrigerant no longer flows into the rear seat evaporator. The surface temperature of the rear seat evaporator rises so that the rear seat evaporator can be defrosted.
