Simulation on the Performance of Lithium Bromide Absorption-Refrigeration System Using Heat Pipe Exchangers

Abstract

This paper describes using the heat pipe exchanger replaces the traditional heat exchanger in the lithium bromide absorption-refrigeration system, and a LiBr solution Physical Properties Computation procedure has been developed to predict the performance of an absorption refrigeration unit. Through simulation to the system, it is seen that not only the heat transfer efficiency is superior to those of the basic cycle, moreover has realized the lithium bromide refrigeration system miniaturization.
