Dynamics of Water Adsorption on Loose Grains in the Presence of Non-adsorbable Gas under Typical Operating Conditions of an Adsorptive Chiller
The effect of a non-adsorbable gas (air) on kinetics of water adsorption on loose grains was studied for the three adsorbents promising for adsorptive chilling:SWS-1L(silica KSK modified by calcium chloride),silica Fuji type RD and FAM-Z02.The experimental conditions were fixed similar to real operating conditions during an isobaric adsorption stage of the basic cycle of adsorptive chiller.Reduction of the adsorption rate was revealed even at the partial pressure of residual air PA as low as 0.06 mbar.Dependence of the characteristic adsorption time on air partial pressure was found to be linear at PA>0.4mbar with the slope depending on the adsorbent nature.Desorption stage was less affected by the residual air.Specific power released during adsorption process was estimated as a function of PA and recommendations how to improve cooling performance are done.
