Dehumidification Performance Evaluation of a Desiccant Rotor Coated With MIL100 (Fe) Under Process Air Conditions

Extended Abstract Adsorbents are the main design factor in the desiccant rotor of a solid dehumidification system because they are directly related to the dehumidification and energy performance [1,2]. Silica gel and zeolite have been widely used in conventional desiccant rotors owing to their wide range of temperature and humidity conditions. However, they have a limitation to dramatically enhance the dehumidification and energy performance of a desiccant rotor owing to its high regeneration temperature and low water adsorption capacity [3]. In this regard, MIL-100 (Fe) has attracted attention to overcome this challenge because it has a low regeneration temperature and high-water adsorption capacity [4,5]. However, studies on the desiccant rotor coated with MIL-100 (Fe) have been very limited. Therefore, the moisture removal capacity (MRC) and dehumidification coefficient of performance (DCOP) of a desiccant rotor coated with MIL-100 (Fe) must be investigated to figure out the dehumidification and energy performance. In this study, the MRC and DCOP of the desiccant rotor coated with MIL-100 (Fe) were investigated through experiments under various process air conditions. The experimental setup was constructed in the environmental chamber based on the NREL desiccant wheel test guide [6] and ASHRAE standard 174 [7]. The desiccant
