Summary

In this study, simulation of heat and mass transfer in adsorbent bed of adsorption heat pump operating with the released heat of a household refrigerator is performed. The adsorbent bed has a rectangular design. For transferring of heat between the outlets of compressor and condenser into the adsorbent bed, a heat exchanger consists of two parallel plates on which the adsorbent bed is located is designed. The R600a refrigerant leaving the compressor flows into the parallel plate. The temperature of refrigerant between compressor outlet and expansion valve inlet is obtained from experimental data of a household refrigerant. The top of the adsorbent bed is cooled by a fan which operates only during adsorption process. Adsorptive enters and leaves the bed from two ends. Heat and mass transfer equations are solved numerically to determine temperature and concentration distributions in the bed for both adsorption and desorption process. The distribution of these parameters are plotted for the bed and discussed. The study is performed for Fuji RD silica gel-water pair with Freundlich isotherm relationship.
