Abstract
A device for preventing icing in a thermostat-controlled evaporator in an air conditioning unit for motor vehicles including a first sensor for sensing the speed of the air through the evaporator and preferably also a second sensor for sensing the humidity of the air. A control unit sets the thermostat to a lowest permissible evaporator temperature which is dependent on the speed and humidity of the air.
