ABSTRACT:
An integrated system for engine heat extraction and comfort air conditioning in an automotive vehicle powered by a Stirling engine, the system being used (a) as a part of the heat rejecting means for the Stirling engine located in a compartment outside of the passenger compartment, and (b) for conditioning air within the passenger compartment. The heat rejecting means of the Stirling engine is effective to cool a selected zone of an enclosed working fluid circuit of the engine; the heat rejecting means is divided into two portions, one normally being diposed to reject heat to ambient air conditions and another disposed to selectively impart rejected heat either to air flow for conditioning air for said passenger compartment or to air flow to be aborted to ambient air conditions. The embodiment as disclosed further includes evaporation or heat absorption means and controls therefore to blend dehumidified cooled air with the air warmed by said heat rejection portion to render a total air conditioning system for the passenger compartment which relies in part upon the heat rejection means being continuously employed as an element of the Stirling engine. In another embodiment, the air conditioning system is arranged with appropriate controls to recirculate cool, dehumidified air to the heat rejection means for a reheating cycle before entering the passenger compartment; an ambient dump control is again employed so that the heat rejection means may be maintained in constant operation.
