Summary

The objective of this work is to investigate the feasibility of using wood pulp fiber paper (WPFP) as substrate of rotary desiccant wheel for dehumidification. The sample WPFP coated with silica gel was fabricated using impregnation method. The water vapor adsorption isotherm of the sample was tested. Additionally, an experimental system was set up to test dehumidification performance of the rotary desiccant wheel with WPFP as substrate. The results show that the water adsorption capacity of the sample WPFP coated with silica gel is close to that of pure silica gel under the condition of 20oC, RH < 70%. In winter condition, the maximal dehumidification capacity of the rotary desiccant wheel with WPFP as substrate can be 0.91 g×kg-1 under revolving speed of 47 r×h-1 and process air flow rate of 245 m3×h-1. The investigation results indicate that the WPFP can be an alternative for the
substrate of desiccant wheel.
