Sukatme SP, Solar Energy, Tata McGraw-Hill, New Delhi, 2004. The performances and effectiveness of the unit was studied by determining refrigeration effect (RE) and  coefficient of performance (COP). Various components were modeled in computer and analyzed using ANSYS. A parabolic solar trough was used as a source of heat. A prototype model was designed, fabricated in laboratory using scrap material and tested performance of the unit has been analyzed. Our objective was to trivialize the role of circulating ratio and simultaneously achieve higher COP. Ammonia-water based system has good COP but generally vapor absorption refrigeration system requires high generator temperature and high circulating ratio aided by a powerful pump. Applications in developing countries such as air-conditioning, vaccine storage or large scale food preservation have been the subject of scientific research. ![]() ![]() Solar refrigeration may have applications in both developed and developing countries.
