Abstract
An air conditioning system for vehicles includes a restriction control device that reduces the consumptive power of the air conditioning system by reducing the cooling ability of the air conditioning system when a cooling load of an interior of the vehicle has increased over a predetermined level, and when predetermined conditions are satisfied. In the system of the present invention, a water temperature sensor or a switch for detecting the opening of a roof window or a double sliding window is not necessary. In the present invention, under certain predetermined conditions, 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 control may reduce waste power to prolong the life of equipment, and which may achieve an improved and comfortable air conditioning state, even when a roof window or a double sliding window is open.
