<p>A method (400, 1100) and apparatus (500, 1200) for producing work from heat includes a boiler (510) which is configured for heating a pressurized flow of a first working fluid (F1) to form of a first vapor. A compressor (502) compresses a second working fluid (F2) in the form of a second vapor. A mixing chamber (504) receives the first and second vapor and transfers thermal energy directly from the first vapor to the second vapor. The thermal energy that is transferred from the first vapor to the second vapor will generally include at least a portion of a latent heat of vaporization of the first working fluid. An expander (506) is arranged to expand a mixture of the first and second vapor received from the mixing chamber, thereby performing useful work after or during the transferring operation. The process is closed and enables recirculation and therefore recycling of thermal energy that is normally unused in conventional cycle approaches.</p> |
