This paper presents the results of studies on the enhancement of heat and mass transfer in an adsorber which is the main element of an adsorption chiller. A silica gel/water adsorption pair was examined. Experimental studies that refer to adsorption dynamics in a layer of silica gel covering directly the heat exchanger pipe were performed. Adsorption was conducted under different process conditions. Gas flow rate and size of grains were changed. Breakthrough curves and temperature changes with time were determined.
