Abstract

A transient two-dimensional numerical model of combined heat and mass transfer in the adsorbent bed of a silica gel/water adsorption chiller is presented for a cylindrical bed with annular fins. The bed transient transport behaviors are discussed for all cycle phases. Complex flow patterns are found for isosteric heating and cooling phases due to the simultaneous occurrence of the adsorption and desorption processes. Furthermore, the effects of bed configurations such asfinspacing, bed height, andparticle size on the performance of the system are examined. Results show that fins in general reduce the COP of the system; however, for a given total cooling power, the bed size can be reduced dramatically, when fins are employed at the cost of slightly lower COP. It is also shown that there is an optimum particle diameter associated with each bed configuration that maximizes the COP, TCP, and SCP of the system.
