Auxiliary heating and air conditioning unit for a diesel powered transport vehicle

A system, comprising:

• a compact, AC operated auxiliary heating and air conditioning unit operable in the cabin of a transport vehicle powered by an internal combustion engine;
• an auxiliary power unit (APU) having an air-cooled engine directly coupled to a brushless generator providing simultaneously a high voltage AC output and a low voltage DC output, operable, when coupled to a fuel supply, exhaust and electrical system of the transport vehicle, to supply the AC voltage to the auxiliary heating and air conditioning unit and to at least one AC branch circuit in the cabin of the transport vehicle, and to supply the DC voltage to the electrical system of the transport vehicle;
• control means coupleable with the auxiliary power unit and the auxiliary heating and air conditioning unit for controlling the distribution of the high voltage AC output and the low voltage DC output of the auxiliary power unit and controlling the operation of the auxiliary heating and air conditioning unit and the auxiliary power unit;
• and
• harness means for coupling the AC output to the auxiliary heating and air conditioning unit and the at least one AC branch circuit, the DC output to the electrical system of the transport vehicle, and the control means to the auxiliary heating and air conditioning unit and to the auxiliary power unit.
