Abstract

The performance of a solid sorption refrigeration system that uses SrCl2 and NH3 as the working pair is analysed based on the heat and mass transfer aspects of the solid sorbent reactors (absorber/generator). The transient, heat and mass transfer model duly considers the effects of reactor wall mass and contact conductance between the reactor wall and the bed. A decent comparison is obtained between the theoretical results and published experimental results on a reactor. The complete system consisting of two absorber/generators, condenser, expansion valve and evaporator is then analysed using the heat and mass transfer model of the reactors. Results are obtained in terms of the coefficient of performance (COP) and specific cooling power (SCP). Results show the possibility of optimizing the bed and operating parameters so as to obtain high COP and/or SCP. The bed thickness, sink temperature and the global reaction advancement are found to affect the performance of the system significantly.
