Parametric analysis of organic Rankine cycle with cogeneration of heat and power operating with geothermal and solar energy in Ramsar

The simultaneous use of Renewable energy such as geothermal and solar as a stimulus of thermodynamic cycle is almost a new idea has been recently consider by researches and so far little research has been published about it. In this study parametric analysis of organic Rankine cycle with simultaneous stimulation of hybrid solar and geothermal energy to produce electricity and hot water has been considered and the effect of evaporator temperature and pinch point difference and also the effect of condenser on organic Rankine cycle operation from the view point of energy, exergy and exergo-economic have been mentioned. Parametric analysis result shows that the temperature increase in evaporator has positive effect on cycle operation and causes the increase in electricity efficiency and decrease in irreversibility. Also, the increase in pinch point and condenser temperature has a negative effect on cycle operation which causes decrease in electricity efficiency and increase in irreversibility. In addition from the economic point of view, the increase in evaporator and pinch point temperature causes the decrease in capital coast rate, and the increase in condenser temperature causes the increase in the capital cost rate. Also the solar radiation change has the positive effect on system operation based on exergo- economic, furthermore it causes the increase in energy and exergy efficiency. Also the solar radiation change has the positive effect on system operation based on exergo- economic, furthermore it causes the increase in energy and exergy efficiency
