The performance of low temperature waste heat driven adsorption cooling systems depends on the thermophysical properties of the adsorbent/refrigerant pair as well as the performance of the adsorber/desorber heat exchanger. Therefore, it is important to investigate the local heat and mass transfer phenomena in the adsorber. This study deals with two dimensional numerical simulations to clarify adsorption characteristics in the plate-fin and tube type adsorber heat exchanger during adsorption process using activated carbon fiber (ACF) of type A-20 and ethanol pair. It is found that the cooling capacity can be enhanced by optimizing fin pitch. Simulation results also show that cooling capacity increase with the increasing of fin (ACF) height and the decreasing of fin thickness.
