Abstract

Adsorption desalination cum cooling is an innovative and promising technological advancement that captures water vapour from the evaporator by adsorption, offering a sustainable solution for freshwater production and cooling. This work explores an unconventional cycle incorporating mass and heat recovery using pressure equalization between the adsorption beds of a two-bed silica gel-water adsorption desalination cum cooling system (ADCS). Our investigation focuses on two cases: When the evaporator temperature is lower than the cooling water temperature (desalination cum cooling) and when these temperatures are equal (desalination) of the system under various operating conditions, accounting for the effects on evaporator vapour generation and water vapour adsorption and desorption in the adsorption beds. The results show that the small-scale system can attain a Specific cooling power (SCP) of 105.66 W kg^-1 with a Specific daily water production (SDWP) of 4.46 kg_w kg^-1_(sg)-d^-1 and performance ratio (PR) of 0.28 when operated for desalination cum cooling purposes. There is an increment in water production of 102.69 % when the system is operated for desalination application as it yields water with SDWP of 9.04 kg_w kg^-1_(sg)-d^-1 and PR 0.44 at the inlet temperature of 90 °C hot water, 28 °C cooling water along the optimal mass and heat recovery time of the 30 s.

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
