Abstract
An integrated, self-contained portable power and cooling system includes a combustion generator and a scroll-type expander driven by combustion gas discharged from the gas generator, wherein the expander is connected in driving relationship to a scroll air compressor that provides compressed combustion air to the gas generator. Inlet air to the gas generator may be preheated by spent combustion gas discharged from the expander. A drive shaft driven by the expander is connected to a fuel pump, an electrical generator, and a refrigerant compressor. The scroll refrigerant compressor supplies refrigerant to a condenser evaporator cooling circuit for cooling a zone directly or indirectly via an auxiliary cooling loop in heat exchange relationship with the evaporator. The system has application in a man-portable system capable of cooling an individual in a high temperature environment and supplying electrical power.
