Sorption properties for different types of molecular sieve and their influence on optimum dehumidification performance of desiccant wheels

Development and Characterization of Mesoporous Silicate–LiCl Composite Desiccants for Solid Desiccant Cooling Systems

“…It can be seen from Figure 7 that dynamic sorption curves approach near-exponential shapes; thus, the rate of adsorption can be calculated by the linear driving force model (LDF): 29 (4) in which dx/dt indicates the sorption rate, k the rate coefficient (s −1 ), x the equilibrium water sorption quantity (g g −1 ), and x t the dynamic water sorption quantity (g g −1 ). With integration of eq 4, the dynamic water sorption quantity of a desiccant can be obtained:…”

Introduction of a new definition for effectiveness of desiccant wheels

“…In their recent paper, they investigated on the effect of a new adsorbent on desiccant cooling system and achieved 35% efficiency increase to the silica gel [7]. Also Cui [8] and Golubovic et al [9] conducted independently two different studies on the improvement of the adsorbent.…”

“…If its value is taken zero, we will have an ideal desiccant wheel in which the air is completely dehumidified. The last definition is the most useful one in the desiccant wheel optimization and usually assumed as objective function [9,11,13].…”

Experimental study on heat and mass transfer characteristics for a desiccant-coated fin-tube heat exchanger

“…A fixed-bed dehumidifier is an original type of solid desiccant dehumidifier, in which process and regeneration air flow through the bed alternately; achieving both heat and mass transfer [4,5]. Considerable research [6][7][8][9][10] has been conducted in recent years into desiccant wheels. The rotary desiccant wheel includes an internal matrix of a base material, with a desiccant material impregnated on its surface.…”
