In the recent times, the use of solar energy for the refrigeration purpose has been increasing day by day. Generally, solar used for cooling purpose has proposed many advantageous features in the refrigeration field. The cooling path is basically depends on the amount of solar radiation. The more amount of solar radiation directly increases the C.O.P. of the system. This research paper, the solar cooling is done with the help of an ejector refrigeration system. The exergy analysis is used to determine the various losses. This paper deals with the exergy analysis to identify the losses and optimum conditions for driving such a refrigeration system. This paper also deals with the impact of losses on the performance of the system. To achieve this analysis for energy and exergy is carried out. The exergy analysis of a cycle identifies the performance of each component of the cycle. Keywords: Solar Collector, Ejector, Generator, Condenser, cooling load, exergy analysis I. The Solar Driven Ejector Refrigeration System- The models of the various parts of the solar-driven ejector refrigeration system, which are used for simulation in this paper, are described in this. The schematic of the system is shown in Figure 1.1. A solar thermal collector is used to supply heat to the generator as a major energy source for the ejector refrigeration subsystem, via a thermal storage and an auxiliary heater. An evaporator provides cooling to the conditioned space. In this case, the cooling load is assumed to be the already introduced small 150 m 3 office building. Details of each subsystem are described in the following section, starting with the model of the solar collector subsystem, followed by the ejector refrigeration subsystem, and the cooling load.
