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.

Passive low temperature heat sources organic working fluid power generation method

The present invention relates to a passive type organic working fluid ejector refrigeration method. The liquid organic working fluid of the reservoir is added to evaporator using gravity. Then the refrigerant absorbs heat during evaporation in the evaporator. When the refrigerant temperature and pressure increases to a certain value, the self-operated pressure regulator valve automatically opens and the ejector begins to work. After condensing in the condenser, the working fluid divided into two streams. One stream returns to the reservoir and the other one flows into the cooling evaporator of refrigeration cycle to produce chilled water about 12&#xb0; C. When the liquid refrigerant is completely evaporated in the evaporator, the self-operated pressure regulator valve opens and the working fluid flows into the evaporator from the reservoir. A certain quality of the working fluid is closed in the evaporator, preparing for a new work cycle as above-mentioned. The system of the present invention can use organic fluid as the working fluid to utilize the low-temperature heat sources range from 60 to 200&#xb0; C., using groundwater, river (sea) water or air as cold source and using gravity to transport liquid working fluid.
