Abstract (en)

[origin: WO2012063275A1] The present invention concerns a method and a system for converting thermal power delivered from a variable temperature heat source into mechanical power by means of a closed thermodynamic cycle. The cycle is characterized in that it operates between a higher temperature (Thigh) and a temperature substantially equal to ambient temperature (Tamb), wherein said higher temperature (Thigh) is much higher than ambient temperature (Tamb), said closed thermodynamic cycle comprising an adiabatic compression process for changing the temperature of a two-phase mixture from said ambient temperature (Tamb) to a lower temperature (Tlow) and to change the specific entropy value of one phase of said two-phase mixture from a first specific entropy value (si, s3) to a second specific entropy value (s2), said second specific entropy value (s2) being lower than said first specific entropy value (s1, s3) and said ambient temperature value (Tamb) being lower than the value of said lower temperature (Tlow).
