CFD Analysis of Solid Desiccant Dehumidifier Wheel

Abstract

Desiccant dehumidifier wheel is the crucial alternative for conventional components used in HVAC system. Desiccant dehumidifier wheel is an essential and pivotal component that can be used in building heating, ventilating, and air conditioning systems in order to reach significant energy savings and to use renewable sources. It is very complicated to optimize the air handling units based on desiccant wheels instead of conventional components and it requires suitable simulation tools. In the present paper simulation is carried out with different temperature and different relative humidity. One-dimensional model is considered for developing temperature and velocity profiles along the channels. The model is used to analyze the impact of different working conditions on desiccant wheel performance. Different performance criteria are imported and it is used to check out the optimal desiccant wheel configuration.
