Performance evaluation of rotary dessicant wheels using a simplified psychometirc model as design tool

In the present communication, a psychometric model has been presented to evaluate the performance of rotary desiccant wheels based on different kind of desiccants e.g. silica gel and LiCl. The developed psychometric model is based on simple correlations between the relative humidity and enthalpy of supply and regeneration air streams. The model is used to predict the performance of three type of desiccant rotors (Type-I, II and III). The model is tested corresponding to a wide range of measurement data. The developed psychometric model is simple in nature and can be used as design tool for performance evaluation of different kind of desiccant rotors.
