This paper presents the experimental research on the
sorption dehumidification of air and solution regeneration
process with packing tower structure by the liquid
desiccant H2O/LiCl. The air conditioning system utilizes
low-grade heat such as solar energy, and can provide
comfortable air temperature and humidity with good
indoor air quality. Water is used as the refrigerant so that
it is environmentally friendly.
From the results of experiments, the average mass
transfer coefficient of the packing regenerator is 4 g/
(m2 s). In the experiments of dehumidification, it is found
that there is maximal tower efficiency at a suitable
humidity of the inlet air. Effective relations of heating
temperature with the outlet parameters of the regenerator
are obtained. The dehumidifier and regenerator are the key
components of the new type of healthy air conditioning
system-liquid desiccant evaporation cooling system, and
the measured data for them is presented in this paper.
