feasibility study of solar ejector cooling cycle in different weather conditions

Today, renewable energies are of more interest due to the depletion of the ozone layer, an increase in the cost of fossil fuels, and their friendliness with the environment. the sun is a great source of energy which is readily accessible. it has many applications in lighting, heating, and cooling. in this study the thermal performance of a solar ejector cooling cycle is evaluated using several different working fluids. the effect of operating conditions-- namely the generator, condenser, and evaporator temperatures-- on the system performance is also investigated. based on weather conditions in different regions, the performance of ejector cooling cycle in several months of the year is also determined. the results show that the operating conditions have a determinant effect on cycle performance. it is observed that an increase in the generator exit temperature results in an increase in cycle coefficient of performance. it is also deduced that the rates of cop increase for the evaporator temperature ranges of 13-15°c and 7-9°c are about 8 and 6% respectively. it is also concluded that a larger collector area is required in warmer weather conditions.
