Engineering Approach to Modeling of a Sorption Bed of a Single-Stage Adsorption Chiller

Abstract

The paper presents prospects of modeling sorption beds based on analysis of parameters characterizing adsorption chillers. The crucial influence of the heat transfer coefficient â„Ž between the bed and the fluid (water) in the heat exchanger on sorbent bed dimensions of an adsorption chiller is determined. It has been shown that improved heat transfer conditions in a bed will allow to reduce the dimensions of the adsorption chiller at preserved Coefficient of Performance. The results of the calculations are presented as heat exchange surface and Cooling Capacity in function of heat transfer coefficient. Moreover the paper presents the leading directions of optimization of the sorption bed design in terms of heat and mass transfer intensification.
