In air-conditioning field, a dehumidification has become increasingly important for human health and comfort especially in hot and humid climates. However, a conventional mechanical dehumidification with a vapor compression refrigerator has some problems. Therefore, much attention has been paid recently to a desiccant air-conditioning system as an alternative to the conventional system. In this paper, we focus on a desiccant air-conditioning system using a rotary desiccant wheel. The purpose of this study is to develop the simulation model of the desiccant wheel that can be applied to the various operating conditions. In this paper, the simulation model is validated under indoor air circulation condition by comparison with the detailed experimental results. In the model, the heat and mass transfer phenomenon in both air channel side and desiccant wall side are considered in detail. As a result, the simulation results of outlet humidity and temperature were in good agreement with the experimental results under indoor air circulation condition and then the simulation model was validated.
