ABSTRACT:
To supply heat to the passenger compartment of an automobile car body immediately upon entering it, an approximately triangular housing has two branch outlet ducts converging from the opposite ends of a main inlet cross duct including a fan chamber containing a reversible electric fan. This fan initially draws cold air into the fan chamber of the main inlet cross duct and forces it through an electric heating coil and then through one of the two converging branch outlet ducts to a common outlet containing a freely pivoted damper which in response to the pressure of the forced air swings to cut off air flow from the other converging branch outlet duct and at the same time directs the heated air through a horizontal transverse duct into the passenger compartment. When the compartment has been thus heated preliminarily, the operator de-energizes the electric heating coil and reverses the fan, causing it to direct outside air through the conventional engine radiator-connected liquid heater of the automobile and then through the opposite converging branch outlet duct. Thereupon the thus-forced air causes the damper to swing to an opposite position, closing the first converging branch outlet duct and thenceforth supplying air heated by the conventional heater to the passenger compartment. Electricity for the electric heating coil is provided by the car alternator and/or storage battery.
