Cooling, heating and power generating device using automobile waste heat

A cooling/heating and power generating system which is powered by waste heat from an automobile engine, comprising

• an engine which produces useful energy and waste heat, said waste heat being dissipated from said engine by waste gases in an exhaust tube and by a cooling fluid,
• a radiator connected to said engine and receiving said cooling fluid from said engine,
• a heat absorber disposed between said engine and said radiator and receiving said cooling fluid prior to its delivery to said radiator,
• said heat absorber including a cooling medium in thermal contact with and being heated by said cooling fluid,
• a heater mounted on said exhaust tube and connected to said heat absorber, said heater receiving said cooling medium from said heat absorber, said cooling medium being in thermal contact with and being heated by said waste gases in said exhaust tube,
• an expansion turbine connected to said heater and receiving said cooling medium from said heater, said expansion turbine being driven by said cooling medium heated in said heat absorber and said heater,
• a condenser connected to said expansion turbine and receiving said cooling medium therefrom, said cooling medium being condensed in said condenser,
• first valve means disposed between said expansion turbine and said condenser for controlling the delivery of said cooling medium to said condenser,
• a liquid receiving tank connected to said condenser and receiving said condensed cooling medium from said condenser,
• a pump connected to said liquid receiving tank and pumping said condensed cooling medium back to said heat absorber,
• said heat absorber, heater, expansion turbine, condenser, liquid receiving tank, and pressure pump forming a circulation loop for said cooling medium,
• said expansion turbine being driven by waste heat from said engine and being a source of power auxiliary to said engine,
• said system further comprising a cooling circuit for cooling said automobile comprising a cooling/heating apparatus connected to said liquid receiving tank and receiving said condensed cooling medium from said liquid receiving tank, a fin tube connected to said cooling/heating apparatus and evaporating said condensed cooling medium after it has passed through said cooling/heating apparatus, a compressor connected to said cooling/heating apparatus and located downstream of said fin tube, said compressor compressing said evaporated cooling medium and delivering said evaporated cooling medium to said first valve means for reintroduction into said circulation loop, and second valve means disposed between said liquid receiving tank and said cooling/heating apparatus for controlling the delivery of said condensed cooling medium into said cooling circuit.
