ABSTRACT:
Components for HVAC systems used in hybrid and fuel cell vehicles are mounted in modular configuration on a frame with air conditioning components connected to one another by metal pipes welded to the components. An alternating current motor, integral with a compressor, is driven by 310 volt alternating current from an inverter, which inverter converts 310 volt direct current that is used to power the vehicle. PTC heaters in fluid communication with an evaporator employed by the air condition system are directly energized by the 310 volt direct current. The modular system is mounted directly on the chassis of the vehicle, facilitative assembly of the vehicle, and is readily removable as a unit from the chassis for repair or replacement.
