Summary
A desiccant air conditioning system is getting attention because it can improve the indoor air quality. In the desiccant wheel, as very complex phenomena occurs in the desiccant wheel, simulations have been carried out to grasp these phenomenon. So far, most of the simulation models have been based on only one air channel. In these models, boundary conditions vary periodically so that these models have to deal with unsteady conditions. But in this paper, a static simulation model of the desiccant wheel is suggested. As the authors' model is static, they can solve steady-state conditions without considering unsteady terms. This model is very useful for the system design. Experiments are carried out to confirm the validity of the model. The authors use the desiccant wheel HY-SG produced by NICHIAS Corporation. This wheel adopts the silica gel as a desiccant. Experiments are conducted using the apparatus that can make the inlet conditions of the process and regeneration air constant. Simulation results are compared with experimental ones. As a result, simulation results agree with experimental ones well. Therefore, the validity of the model is confirmed (see also this Bulletin, reference 2008-0787).
