Abstract

Desiccant cooling
technology is an environmentally attractive alternative to conventional
mechanical air conditioning. A desiccant cooling system is a suitable way to
improve indoor air quality due to its superior humidity control and it also
provide as economical and cleaner for hot and humid regions. The most important
component of the technology is the desiccant wheel which is used to remove the
humidity of air. In this study, the analysis of dehumidification and humidity
removal process of desiccant wheel were carried out using the performance data
given by manufactures of the desiccant rotary wheel. Two parameters (F_d,
F_r) were defined for the analysis of the process. It was found that
dehumidification and regeneration processes do not occur at constant wet bulb
temperature. An equation for F_d and F_r which depends on
the humidity ratio of outdoor air and regeneration temperature was composed.
