Energy conversion system

摘要: The invention provides a method and apparatus for recovering work from heat source providing cooling that comprises: a. selected working fluid comprising at least two components; to first low pressure pump; b. feeding the dividing means; c. into stream second stream, d. transfer zone heating higher temperature, e. temperature separation means, f. separating volatile component enriched depleted stream; g. h. an expansion means i. expanding lower pressure; j. expanded mixing k. l. high pump then exchange wherein is transferred produce condition of m. convert portion energy mechanical energy; n. o. streams provide combined p. returning feed-line pumping stage fluid. Preferably, group consisting ammonia water; sulfur dioxide mixed hydrocarbons; brine; or brine. More preferably, comprises water ammonia, salts. Most consists essentially water. In especially preferred embodiment, substantially pure component. also specially configured carry out claimed above.
