Absorption Refrigeration System can play a vital role in electrical energy conservation because they can be operated on waste heat energy. The intermittent nature of solar power may be a dominant think about exploring well-designed thermal energy storages for consistent operation of solar thermal-powered vapor absorption systems. Our goal is to design the cooling unit based on a vapor absorption system. For this purpose, we have done a literature survey, mathematical modeling, simulations, and made computer-aided design models of our unit. We verified our component operating conditions.Thermal energy storage acts as a buffer and moderator between so- lar thermal collectors and generators of absorption chillers and significantly improves the system performance. Vapor absorption chillers are available in half, single, double, and triple-effect modes of operation and operate at temperatures starting from 75 to 220^oC to supply a cooling effect with COPs starting from 0.3 to 1.8. Thus, the choice of appropriate solar collectors and thermal energy storages are two significant decisions affecting the consistency of output of a vapor absorption cooling system. This review covers all the major aspects of such systems. It also covers the research work done on this subject till now. Though there is still room for a lot of research work in this area of refrigeration systems. Moreover, the conclusions and recommendations are also discussed.
