Mathematical simulation of a new passive solar collector and its performance evaluation in solar thermally driven cooling systems for different climate condition of Iran

A numerical model of the new passive solar collector is performed, then the thermodynamic analysis of the thermal cooling systems is applied to the model in three systems: absorption, ejector, and Rankin for different climate condition of Iran, in this work. The results show that a large percentage of the energy required of the systems is available by the solar, even at some hours of the day; the total energy can be supplied by the solar. In all systems, the highest percentage of energy supplied by the solar and the highest solar coefficient of performance is related to Abadan and the lowest amount of it is related to Ramsar. In the absorption system, with the increase of generator temperature, the solar fraction decreases, and the solar coefficient of performance increases, but in the ejector and Rankin systems, the solar fraction and the solar coefficient of performance increases with the increase of generator temperature. In all systems, with the increase of evaporator temperature, the solar fraction and the solar coefficient of performance increase.
