The present invention relates to a passive low temperature heat energy organic working fluid power generation method and system, Comprising: organic working fluid in a first evaporator and a second evaporator are heated to evaporate; when a pressure of the organic working fluid reaches a setting pressure, a self-operating pressure control valve at an outlet of the evaporator is triggered opening by a working pressure, and steam of the organic working fluid flows into a turbine, pushes the turbine to work, and drives a generator to output electric energy; after work is completed, the steam flows into a condenser to be condensed, and working steam is output in turn through the first evaporator and the second evaporator, and thus the turbine is driven continuously to work and output electric energy. Compared with the prior technology, the present invention has reliable performance, and is operated by heating and evaporating of the working fluid in a closed space to achieve increased pressure. |
