Abstract
A compact rooftop air conditioning unit for a vehicle, said unit having an evaporator coil located adjacent to a condenser coil. At least one cylindrical blower is mounted adjacent the evaporator coil and is arranged to provide conditioned supply air to the interior of the vehicle. An electric motor is used to turn the shaft of the blower and a condensate pump is secured to the shaft for pumping condensate generated by the evaporator coil back over the condenser coil. An electrically driven compressor is housed within the unit and is arranged so that no refrigerant lines pass outside of the unit. An inverter is also housed within the unit and provides a regulated input to the compressor and the evaporator and condenser drive motors.
