METHOD FOR CONVERTING THERMAL ENERGY

摘要

The present invention provides a method to convert thermal energy which includes: an evaporation step which obtains a low-temperature heated fluid of a temperature lower than an intake temperature by heating a working fluid whereby two fluids having different boiling points are mixed whereby the working fluid is evaporated in at least part of the evaporated working fluid; a separation step which separates the evaporated working fluid into a concentrated fluid and a diluted fluid; an expansion step which obtains a consumed concentrated fluid by expanding the concentrated fluid and then converting into useful energy; a combining step which obtains the working fluid by combining the consumed concentrated fluid with the diluted fluid; a condensing step which condenses the working fluid by cooling the working fluid; a pumping step which increases the pressure of the condensed working fluid and supplies the working fluid to repeat a heating step; a first heat exchange step which converts the consumed concentrated fluid into a cooled concentrated fluid and the working fluid into a first pressure-increased working fluid by heat-exchanging the consumed concentrated fluid and the working fluid before repeating into the evaporation step; and a second heat exchange step which heat exchanges the working fluid and the heated fluid obtained in the heating step to make the temperature of the evaporated working fluid higher than the temperature of the low-temperature heated fluid and heat exchanges the diluted fluid separated in the separation step and the low-temperature heated fluid.
