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 (Fd, Fr) 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 Fd and Fr which depends on the humidity ratio of outdoor air and regeneration temperature was composed.
