ABSTRACT:
An apparatus is described for heating and cooling a truck cab through the utilization of an auxiliary water cooled engine mounted on the truck. The auxiliary engine has an airconditioner compressor mounted thereon which supplies refrigerant to a condensor which is operatively connected to the air-conditioner evaporator on the primary engine of the truck so that the interior of the truck cab may be cooled without running the primary truck engine. The hot coolant water in the auxiliary engine is fluidly connected to the heater core of the truck heating system so that the interior of the cab may be heated without operating the primary truck engine. An alternator is mounted on the auxiliary engine and is electrically connected to the truck electrical system.
