Performance evaluation and simulation of a new absorbent for an absorption refrigeration system

In this article the employment of an alternative absorbent used in absorption refrigeration cycles to replace the absorbent currently employed in this kind of enginnes, lithium bromide, has been studied. The alternative system consits of absorbent (LiBr:CHO2K=2:1 by mass ratio) and refrigerant (H2O). To compare the performance of both systems, a program to simulate theoretical absorption cycles from empirical data has been developed. By means of the program, the efficiency of the absorption cycles have been evaluated. Also the influence of changes in the operation conditions on the performance of each cycle has been analysed. The study allows an insight into the internal parameters and into the possible behaviour for more severe conditions than those studied.
