Abstract

The study aims at clarifying the performance of a 3-bed, mass recovery silica gel-water adsorption refrigeration cycle. The cycle with mass recovery can be driven by waste heat at near ambient temperatures (between 50 and 90°C). All components of adsorption cycle are operated in different pressure levels. The 3-bed chiller with mass recovery process utilizes those pressure levels to enhance the refrigerant mass circulation. The innovative adsorption chiller comprises with three sorption elements (SEs), one evaporator and one condenser. The configuration of SE1 and SE2 are uniform but the configuration of SE3 is taken as half of SE1 or SE2. Two cycles (cycle-1, cycle-2) with mass recovery process are used and compare the performance with each other. In cycle-1, mass recovery process occurs between SE3 with either SE1 or SE2 and no mass recovery between SE1 and SE2 occurs. In cycle-2, mass recovery process occurs between SE1 and SE2, and no mass recovery process occurs between SE3 with either SE1 or SE2. The mathematical model shown herein is solved numerically. Simulated results are obtained from transient to cyclic steady state. Simulated results show that the COP and SCP of cycle-1 are better than those of cycle-2.
