The continuous and rapid development of countries ran in a monumental increase in the demand of energy utilization. For this entailment of renewable energy, such as solar energy for an eco-friendly process of refrigeration by Vapor Absorption process is looked to be a blessing in present scenario. Putting back the electrical energy with solar energy will shorten the use of high grade electrical energy. Solar energy based refrigeration system is one of the best assuring technology to fulfill the

... boosting demand for refrigeration purpose. A solar dr-ivan Lithium-Bromide absorption cooling system was studied. It was an intermittent system in which water used as a refrigerant and Li-br used as a absorber. This paper provides an analytical approach to the study of the vapor absorption refrigeration system. By the application of first and second Law of thermodynamics with Mass and energy balance equation. The main aim of this work is to study of Lithium Bromide-Water (LiBr-H2O) absorption System with the Capacity of 1.5 ton. The various components of VARS system Absorber, Heat-exchanger, Generator, Condenser, Expansion Valve and Evaporator. the COP of the system is calculated on the basis of hot water as a heat source. The basic idea of this work is taken from solar water heating system.
