Résumé

In this paper, a solid adsorption cooling system with silica gel as the adsorbent and water as the adsorbate was experimentally studied. To reduce the manufacturing costs and simplify the construction of the adsorption chiller, a vacuum tank was designed to contain the adsorption bed and evaporator/condenser. Flat-tube type heat exchangers were used for adsorption beds in order to increase the heat transfer area and improve the heat transfer ability between the adsorbent and heat exchanger fins. Under the standard test conditions of 80°C hot water, 30°C cooling water, and 14°C chilled water inlet temperatures, a cooling power of 4.3 kW and a COP for cooling of 0.45 can be achieved. It has provided a specific cooling power of about 176 W/(kg adsorbent). With lower hot water flow rates, a higher COP of 0.53 can be achieved. [Reprinted with permission from Elsevier.
