Comparison of an adsorption refrigeration unit operating with two and four adsorbers

Abstract

Adsorption refrigeration systems can be built with one, two or more adsorbers. The most common devices are built of two adsorbers. This fact makes the achieved cooling capacity is variable over time, and in some periods of operation is even 0 kW. Increased number of adsorbers causes the cooling capacity obtained in time is more balanced. The aim of the study is to compare the most popular operating unit with two adsorbers with the installation which continuously work with four adsorbers. It turns out that such a solution can align cooling capacity during the entire process. This solution does not affect the effectiveness of the device, but only on its size. Absorbers are the largest part of the device. So this type of solution is dedicated to wherever it is needed fluently providing cooling capacity and there is no possibility of collecting cooling in tanks.
