ABSTRACT: This study establishes the mathematical model of the shell and tube type adsorption bed structure design, discusses the influence of the
unit-tunnel length on the adsorption bed sheets consumption by numerical solution method, and analysis the influence of the unit-tunnel length and the inlet
velocity of the heat source on the heat transfer performance. Moreover, the heat transfer is studied by fluent simulation respectively from the heat sources of tail
gas and steam. The results show that the steam as the heat source of solid adsorption refrigeration has more advantages than tail gas as.
