Abstract
A compact rooftop air conditioning unit for a vehicle, such as a bus, having an evaporator coil located in front of a condenser coil. A plurality of cylindrical blowers are mounted adjacent the evaporator coil and arranged to provide conditioned supply air to the interior of the vehicle. A single electric motor is connected to an elongated drive shaft which drives the blowers. A condensate pump is included 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.
