Abstract
The dehumidification process is an important process in many applications
in a very large variety of industrial and daily usage products including the
new HVAC systems. Liquid desiccant systems are very efficient systems
that used for that purpose. The present study aim to evaluate the
performance of the proposed liquid desiccant air dehumidifier system which
using calcium chloride solution as a liquid desiccant. The performance
parameters for the air dehumidifier are the reduction ratio of air humidity
and the dehumidifier effectiveness.
The parameters being studied here are the desiccant solution concentration,
desiccant temperature, desiccant flow rate and air flow rate. To perform this
purpose several experimental runs have been done under the following
conditions:
- Desiccant flow rate range : 4 – 8 L / min
- Desiccant temperature range : 10 – 18 oC
- Desiccant solution concentration : 40% , 20%
- Air flow rate range : 0.03 – 0.1 m3 / sec
The experimental results show that, both the air humidity reduction
and the dehumidification effectiveness increase with increasing each
of the desiccant flow rate, the desiccant temperature and the desiccant
solution concentration. Also the results indicated that both the air
humidity reduction and the dehumidification effectiveness are
decreased with increasing the air flow rate. Empirical correlations
based on the present experimental results for both the air humidity
reduction and the dehumidification effectiveness in terms of the
different operating conditions were developed.
