Description
Summary:The main objective of this study is to determine the coefficient of performance (COP) for absorption chillers. By using a reversible Carnot cycle process the optimum coefficient of performance (COP) and ammonia/water ratio are obtained. Gas Absorption Refrigeration Unit (Model: RF 10) is a complete laboratory bench top unit for the demonstration and analyze the performance on effect of ammonia/water ratio in performance for absorption chillers. In this experiment the refrigerant is anhydrous ammonia and the absorber is water. The ammonia/water ratios used are in the range of 5% to 30% ammonia in water base on volume percentage in the solution.
