ABSTRACT:
An air conditioning system for vehicles has a cooling circuit and a radiator supplying cooling water to an engine. The cooling circuit includes a compressor, a condenser and an evaporator. The system includes a water temperature sensor for detecting a water temperature in the radiator, and a control device for selectively controlling the opening of ports to allow temperature controlled air to flow into an interior of a vehicle, in accordance with the water temperature, detected by the water temperature sensor, and a target conditioned air temperature. In the system, the power to an air conditioner may be appropriately restricted, and the amount of heat radiation at the condenser may also be appropriately restricted. Consequently, the water temperature in the radiator may be prevented from becoming too hot, thereby preventing instances of overheating and preventing a warning of a potential overheat.
