Abstract
Despite the fact that an absorption refrigerator is required to improve its efficiency, even the optimum design point of the absorption cycle has not been clarified. This research discusses the optimum design method of a double-effect absorption refrigerator, which has spread generally. The objects of the analysis are the three typical double-effect absorption cycles, series, reverse and parallel flow. COP is the evaluation function. Some constraints to drive the absorption cycle normally exist. As the analysis technique, the exterior-point-penalty-function method, which can analyze nonlinear optimization problems with constraints, and the applying-trial-and-error method are adopted to seek the optimum point. As a result, optimum COP for each flow at the point of 90% temperature efficiency were, series 1.47,Reverse 1.49 and parallel. 50.
