Comparative analysis of promising adsorbent/adsorbate pairs for adsorptive heat pumping, air conditioning and refrigeration

The noticeable influence of the metal-to-adsorbent mass ratio on the sorption cycle performance was also demonstrated, showing that utilization of compact finned tube aluminum heat exchanger types (typical mmet/mads = 0.9-1.6) allows a 15-30% cooling COP higher than a traditional stainless steel tube-and-shell exchanger (mmet/mads = 2.4-3.1). Additionally, some brief dynamic considerations are done for most interesting working pairs.
