Abstract:
a combustion powered cooling system comprising:a power loop, wherein a first working fluid flows in the power loop;a cooling loop, wherein a second working fluid flows in the cooling loop;a power unit in operative connection with the power loop and the cooling loop; wherein the power unit includes an expander end and a compressor end, wherein the expander end includes a steam piston, and wherein the compressor end includes a compressor piston, and wherein the power unit also includes means for transferring power from the steam piston to the compressor piston;a steam generator in operative connection with the power loop, wherein the steam generator is operative to produce a superheated fluid from the first working fluid, wherein the power loop is operative to selectively deliver the superheated fluid to the steam piston, wherein the steam piston moves in a first reciprocating motion as the superheated fluid is alternately expanded and exhausted from the expander end, wherein the power transfer means is operative to have the compressor piston move in a second reciprocating motion responsive to the first reciprocating motion of the steam piston, and wherein the compressor piston is operative to compress the first working fluid;a first condenser in operative connection with the power loop, wherein the first condenser is operative to condense the expanded first working fluid to a liquid;a condensate pump in operative connection with the power loop, wherein the condensate pump is operative to return the liquid first working fluid to the steam generator;a second condenser in operative connection with the cooling loop, wherein the second condenser is operative to condense the compressed second working fluid to a liquid, wherein heat is released from the compressed second working fluid;an expansion device in operative connection with the cooling loop, wherein the expansion device is operative to selectively control the flow of the liquid second working fluid therethrough; andan evaporator in operative connection with the cooling loop, wherein the liquid second working fluid passes through the expansion device and expands in the evaporator to a vapor phase; and wherein the second working fluid acquires heat when expanding to a vapor phase; and wherein the vapor second working fluid returns to the compressor end.
