Abstract (en)
[origin: WO2007042215A1] A method for generating mechanical energy from heat is provided. It comprises the steps of: extracting heat from a heat source; transferring the extracted heat to a heat fluid circulating in a closed heat circuit (200, 300) and evaporating the heat fluid by means of the transferred heat while increasing the pressure in the evaporated heat fluid; wherein the heat fluid under high pressure flows through a turbo-machine (22) and thereby performs work while it cools and expands; the heat fluid that has expanded and cooled after flowing through the turbo-machine is condensed again; and the pressure of the condensed heat fluid is increased again by means of the heat of the heat source, and the heat fluid is chosen such that, by using a temperature range with a maximum temperature of no more than 13°C, a vapour pressure difference of at least 0.5 MPa can be realized.
