Abstract
An assist airblower unit for a heating and ventilating system of a motor vehicle. The airblower includes a single motor and two centrifugal fan wheels encased within a shell. The motor drives both centrifugal fan wheels via a shaft. The centrifugal fan wheels have angled blades that draws in air from a lateral air inlet located on the shell. The air is then forced out of the outlet openings into the automobiles interior to either heat or cool the vehicle. The air source either outputs at the front of the HVAC unit or recirculation air, i.e., cabin air.
