EXPERIMENTAL STUDY ON A THREE-BED ADSORPTION CHILLER

This article presents the experimental results of a three-bed advanced adsorption chiller using silica gel - water as the adsorbent - refrigerant pair. The three-bed adsorption chiller comprises three sorption elements (Hexs), one evaporator and one condenser. In the present study, the heat source temperature varies from 55 degrees C to 80 degrees C along with coolant inlet temperature at 30 degrees C and the chilled water inlet temperature at 14 degrees C. Mass recovery process occurs between Hex1 and Hex2 and no mass recovery with Hex3. The performances in terms of cooling capacity (CC) and coefficient of performance (COP) are compared with those of conventional three-bed without mass recovery scheme. Results show that three-bed with mass recovery scheme provides more CC values than those provided by the three-bed system without mass recovery scheme while it provides better COP values for 65 -75 degrees C heat source temperature.
