Abstract

A heating, venting, and air conditioning system utilizes a reformer to provide supplemental heat to a passenger compartment and to improve start-up emissions of an engine of a vehicle or power system. A pump circulates a fluid through the engine and throughout the system. A radiator and heater core transfer heat from the fluid. A first circuit cools the fluid upon circulation through the radiator after circulation through the engine to cool the engine, and a second circuit heats the passenger compartment and cools the fluid upon circulation through the heater core after circulation through the engine to cool the engine. The reformer, which converts a hydrocarbon or alcohol fuel into a reformate, generates heat. A third circuit, defined between the reformer and the pump and interconnected with the heater core, provides the supplemental heat from the reformer to the passenger compartment through the heater core and also to the engine.
