Development and Fabrication of Solar Vapour Absorption Refrigeration System using Parabolic Solar Trough

As the saying goes, "There is no energy crisis, only a crisis of ignorance”. With the minds of research along with scientific investigation, a pathway has led to deep dive into renewable energy sources. In the era of energy crisis renewable energy is seen as a farsighted option with great capability and endurance. This paper deals with application of solar thermal energy with vapor absorption system. In vapor absorption, system heat energy is taken as source of input energy unlike mechanical energy in vapour compression refrigeration system. The performance characteristics and evaluation depends on heat energy supplied and pump work used in the refrigeration system .Hence, here idea of experimental setup developed from this thought that if the heat energy required for the process is extracted from the solar energy and supplied to the generator then energy requirement to the generator can be reduced. Hence, our project novelty is based on the running a vapour absorption refrigeration system using the heat energy extracted from solar energy by using a parabolic solar heat collector. This heat is used to supply the heat required in the generator for the system. Hence, our result of experiment would aim for generation where the input work of electrical energy is given only through pump and other sources of input work are removed. Air-conditioner and refrigerator uses 70% of domestic energy utilized. This work provides a solution for this high energy consuming machines. We hope to take a small step in this direction for future development and establishment of new advancements in this regard.
