Abstract
The chief objective of this study is the proposal design and CFD simulation of a new compacted copper wire woven fin heat exchanger and silica gel adsorbent bed used as part of an adsorption refrigeration system. This type of heat exchanger design has a large surface area because of the wire woven fin design. It is estimated that this will help improve the coefficient of performance (COP) of the adsorption phase and increase the heat transfer in this system arrangement. To study the heat transfer between the fins and porous adsorbent reactor bed, two experiments were carried out and matched to computational fluid dynamics (CFD) results.
Highlights
This article attempts to provide insight into the working principles of a wire woven heat exchanger used in an adsorption cooling system
The test rig was first designed by using 3D SolidWorks CAD tested by computational fluid dynamics (CFD) modelling to predict the heat transfer in the adsorbent bed
The simulation code has been tested for stability in computation and can achieve CFD simulation of the wire woven fin heat exchanger and the different components of the adsorption cooling system
Summary
This article attempts to provide insight into the working principles of a wire woven heat exchanger used in an adsorption cooling system. The installation procedure for a test rig equipped with a data logging system has been specified along with the calibration of sensors. The method followed in conducting tests on a new configuration of adsorption cooling system is described. The purpose of testing the system is to ascertain systems viability and interaction of individual components. The tests were carried out to determine the test rig parameter for use in a CFD simulation. Several routine curves were generated for system components such as the adsorbent bed evaporator and condenser
