摘要：

Kinetic properties of the adsorbent can strongly affect dynamics of an adsorptive heat transformer. in this paper we describe a current methodology and start discussing a new approach for dynamic characterization and optimization of the system "adsorbent-heat exchanger" under conditions typical for heat transformation. Effect of the adsorbent nature, its grain size, residual non-adsorbable gas, heating rate, local shape of adsorption isobar on the adsorption dynamics and specific cooling (heating) power was studied for promising adsorbents of water (Fuji silica RD, FAM-Z02, SWS-1L). Based on these results some demands to an adsorbent optimal from the dynamic point of view have been discussed. (C) 2009 Elsevier Ltd and IIR. All rights reserved.
