Abstract

Abstract The disclosure relates to an environmental protection system comprising a Rankine cycle power loop wherein a working fluid is heated by either the combustion of a fuel or by heat exchange from internal combustion engine exhaust. A high frequency turboalternator is driven by the power loop working fluid for the production of high frequency alternating current. An electrically driven Rankine cycle cooling loop uses a second working fluid to effect cooling of a desired media.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 215 words
An environmental conditioning system for a vehicle having an internal combustion engine with an exhaust outlet comprising: a closed Flourinal 85 power and heating circuit including a vapor generator for the vaporization of Fluorinal 85 by the combustion of a fuel and by heat exchange from the internal combustion engine exhaust, selectively, a turboalternator connected to said vapor generator and driven by said Flourinal 85 for the production of alternating current, a regenerator connected to the exhaust side of said turboalternator, a condenser connected to said regenerator, and a Fluorinal 85 reservoir connected between said condenser and vapor generator including a conduit passing through said regenerator, a closed Freon 113 cooling circuit including an electric motor driven by alternating current from said turboalternator, a compressor for said Freon 113 driven by said electric motor, a condenser connected to said compressor, an expansion valve connected to said condenser, and a dual purpose evaporator and heat exchanger connected between said expansion valve and said compressor, and a closed ethylene-glycol-water cooling circuit comprising the heat exchanger portion of said dual purpose evaporator and heat exchanger, a pump connected to said evaporator, valve means connected to said pump for controlling flow of the etheylene-glycol-water in said cooling circuit, and a heat exchanger connected between said valve and said evaporator.
