Abstract:
A method of converting heat energy generated in an evaporator to mechanical energy by expanding an evaporated working fluid includes evaporating the working fluid in the evaporator and expanding the evaporated working fluid in an expansion device. The expansion is in a low-pressure expansion device which is formed as a roots blower in which the working fluid is expanded and heat energy is converted to mechanical energy.
