Abstract
In an air-conditioning system having two air-conditioning passages serving two different air-conditioning zones but having a cooling degree detector provided in only one of the passages to reduce cost, with the degree to which air is cooled in the other passage being estimated based on a cooling degree detected by the detector and the difference between flows of air passing through the passages or an intake temperature of air entering the passages. On the other hand, when an evaporator is possible to be frosted in one of the passages, air flow amount in the one of the passages is corrected to be increased. Therefore, it can prevent a windshield from being fogged while preventing the evaporator from being frosted.
