ESTUDIO ANALÍTICO DE LA TRANSFERENCIA DE CALOR EN UN ABSORBEDOR DE BURBUJAS

Abstract

This paper presents an analytical study of heat transfer in a bubble type absorber, in order to calculate the heat and mass transfer of water vapor bubbles into the solution of lithium bromide. This contributes to the investigation of absorption refrigeration systems currently in the world researchers are developing, as these are an option for using waste heat in industrial processes. Plus they are easy to adapt to solar collectors to harness solar energy as heat. This is why development and optimization is a major advance in recent decades, precisely because of the increasing concern for energy conservation. Bubble absorbers are attractive because they have high heat transfer coefficients and allow good wetting and mixing between the vapor and liquid. However it works, how other absorbers is limited to the amount of heat that can be detached from the device to perform the absorption of refrigerant. This paper presents the fundamentals of the operation of absorption refrigeration systems, and calculation methodology for calculating the heat transfer to the solution, are based upon previous research by other researchers in the field, so this research is a continuation of the mathematical models of past research, the difference between these studies and this is the use of the working fluid Water - Lithium Bromide and operating conditions which is presented in this paper. The basic design parameters of the absorber were taken from the research of Dr. A. Zacharias [11] and [23] and the numbering was simulated numerically in software Engineering Equation Solver (EES).
