First and second order simplified models for the performance evaluation of low temperature activated desiccant wheels

The proposed models can be used to predict the influence of the inlet process air and inlet regeneration air, on the air process outlet temperature and humidity ratio. The accuracy obtained of the experimental models is more than acceptable, with R2 values greater than 97.4% for outlet temperature and 95.1% for outlet humidity ratio. The first order model was considered to be a good option due to the balance between accuracy and the low number of experimental tests required. However, the second order model allowed a deeper understanding of the behaviour of the air outlet conditions in the DW.
