| 摘要 |
The invention relates to a process for transforming heat having a low temperature into motive power, wherein heat which is carried by a first fluid is used for heating a condensable second fluid which participates in a thermodynamic cycle and wherein the second fluid is expanded thereby producing motive power or thermic energy having a higher potential. The apparatus for putting into practice this process comprises a superheater, in which the first fluid carrying the heat to be transformed and the second fluid circulate, an expansion device for the second fluid which produces motive power, a heat exchanger in which the expanded second fluid and a compressed second fluid circulate, a condenser for transforming the expanded second fluid into a liquid, a compressor for feeding the liquid second fluid to the superheater via the heat exchanger, and a gaseous fluid circulating through the condensor which mixes via ports and a convergent nozzle in the superheater with the first fluid. An environmental conditioning apparatus may be connected to receive a portion of the output from the expansion device or the condensor to effect a heating or cooling operation. |
