Abstract

In this paper the environmental factors that effect on the performance of organic Rankine cycle with a linear parabolic solar receiver is investigated. Due to the fact that the performance of the receiver has an important role in the total efficiency of solar power collection, the amount of heat losses should be minimized. On the other hand, the amount of heat losses is also effective on the exergy losses and minimizing the thermal dissipation will also lead to a reduction of exergy losses. Thus, identifying factors that help to improve the efficiency of the first and second laws of thermodynamics is necessary. Due to this point the different environmental factors (such as the wind blowing speed in the environment, solar radiation intensity, sun radiation angle, flow rate of heat carrier fluid, ambient temperature) in the recipient and also the kind of dry fluid in the Organic Rankine Cycle should be investigated. For this intention the energy and exergy model of organic Rankine cycle with initial stimulus of solar recipient has been developed in the EES software. Results indicate that the greatest amount of irreversibility occurs in the evaporator and receiver. Also the amount of irreversibility is reduced by increasing in the receiver temperature (the average temperature of the inlet and outlet of the recipient). It can be observed from other results that the amount of irreversibility is increased by increasing in the radiation intensity and ambient temperature and decreasing in the angle of the sun radiation.
