Abstract: The technique of the invention determines whether input data for driving and controlling a cooling fan have any abnormality (steps S100 and S110), sets an actual drive level F* of the cooling fan to a high level (Hi) in the event of detection of any abnormality (step S130), and controls a fan motor to drive the cooling fan at the set drive level F* (step S140). This arrangement effectively prevents a temperature rise to an abnormally high level in any of an engine and motors even in the event of any abnormality arising in the input data.

This ventilator has an exhaust-air coupling section and a supply-air coupling section, and a ventilating unit which includes an exhaust-air outlet and a supply-air inlet, a motor for driving an exhaust-air fan and a supply-air fan, the heat exchanger for carrying out heat recovery between interior air and outside air, and a cut-off damper for cutting off a supply-air flow in a supply-air channel. Supply-air temperature sensing means for sensing a temperature of the outside air issues a signal, which prompts the damper to cut off the supply-air flow and reduce a volume of the exhaust-air.

Abstract: An air conditioning system for use in an over-the-road or off road vehicle is provided that provides a method of operation during both engine on and engine off conditions. The method operates the air conditioning system at one capacity when the engine is running, and at a second capacity when the engine is not running. The selection of these capacities is based on the power capacity of the source of electric power from which the air conditioning system is operated. When a storage battery is used to power the air conditioning system during engine off conditions, the second capacity is lower than the capacity at which the system is operated when the engine is running.
