AB  - Desiccant coolingtechnology is an environmentally attractive alternative to conventionalmechanical air conditioning. A desiccant cooling system is a suitable way toimprove indoor air quality due to its superior humidity control and it alsoprovide as economical and cleaner for hot and humid regions. The most importantcomponent of the technology is the desiccant wheel which is used to remove thehumidity of air. In this study, the analysis of dehumidification and humidityremoval process of desiccant wheel were carried out using the performance datagiven by manufactures of the desiccant rotary wheel. Two parameters (Fd,Fr) were defined for the analysis of the process. It was found thatdehumidification and regeneration processes do not occur at constant wet bulbtemperature. An equation for Fd and Fr which depends onthe humidity ratio of outdoor air and regeneration temperature was composed.
