A. Ertas et al., EXPERIMENTAL INVESTIGATIONS ON THE PERFORMANCE OF A PACKED-BED DEHUMIDIFIER FOR VARIOUS CLIMATIC CONDITIONS, Drying technology, 15(3-4), 1997, pp. 1061-1075
To simulate space cooling or drying systems for various geographical r
egions (low, moderate, and high humidity regions) a liquid desiccant s
ystem consisting of a humidifier and dehumidifier has been designed an
d constructed. This system consists of two coupled humidifying and deh
umidifying packed columns filled with plastic Intalox Snowflake packin
g material. Experimental measurements of the dehumidifier performance
utilizing a new cost effective liquid desiccant mixture (CELD), total
desiccant salt content 40%wt to 45%wt (salt comprised of equal portion
s by weight of lithium chloride and calcium chloride)I have been carri
ed out. The effect of different independent varibles such as packing h
eight, air inlet temperature and humidity ratio, and liquid desiccant
inlet temperature, flow rate and concentration on the performance of t
he dehumidifier has been investigated. Experimental results demonstrat
e that the CELD is a promising desiccant for cooling and drying operat
ions.
