Abstract
A compact rooftop air conditioning unit for a vehicle, said unit having an evaporator coil located in front of a condenser coil. At least one cylindrical blower is mounted adjacent the evaporator coil and is arranged to provide conditioned 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 blower drive motor. The heat exchanger coils are mounted in the form of two tube sheets take over the function of a housing, with the drip pan closing the bottom and the unit lid closing the top to form the completed unit.
