Abstract:
Closed fluid flow system and method for producing power from an extraneous heat source, in which a receiver is maintained with a volatile heat transfer fluid medium partly in the form of liquid and partly in the form of gas,
to permit the pumping of liquid therefrom by a pump to an evaporator for evaporation to gas by means of the extraneous heat source, separating of any remaining liquid residue content from such gas, compressing of the separated gas to high compression gas, expanding of the high compression gas in a prime mover to produce power, and cooling and reliquifying of the separated liquid residue content for recycling to the pump,
and furthermore to permit the removing of a refrigerating control portion of the liquid from the receiver for expanding and evaporating such control portion for cooling the contents of the receiver, removing of a compensating control portion of the gas from the receiver, and compressing of the expanded and evaporated liquid control portion and of the gas control portion to low compression gas,
with condensing and cooling of both the expanded gas from the prime mover and the low compression gas for return as liquid to the receiver, and with optional compression of a supplemental portion of the gas from the receiver to form additional high compression gas,
the removed control portions from the receiver being sufficient to maintain in the remaining contents of the receiver an adequately cooled quantity of liquid for pumping to the evaporator.
