Method of converting thermal energy into mechanical one

摘要

In the conversion of the thermal into a mechanical energy a fluid is subjected to a circulating process. For utilising of temp. differences below 100 deg.C a coolant is used as the fluid. Pref. solar energy is used as the thermal one, but geothermal energy may also be used. Typically the thermal energy is subjected to buffer storage. The fluid is evaporated by heat supply, the vapour drives a turbine, and the fluid condensed after mechanical energy generation.
