Abstract

The results of analysis of designs and efficiency of absorption refrigerating machines are considered. Based on the analysis of schemes and designs of modern absorption refrigerating machines used for obtaining cold at various levels, the main characteristic parameters of refrigeration equipment are given, their capabilities and disadvantages are indicated. Methods for evaluating the efficiency of absorption columns and machines are analyzed. It is proposed to study the absorption column as part of the refrigeration machine, as well as to evaluate the efficiency of heat and mass transfer devices, machines exergetic method.
