Résumé

As the bearer of wet load, the desiccant wheel determines the performance of the rotary wheel dehumidification system. In this study, a novel metal organic framework composite adsorbent desiccant wheel (MOF DW) was prepared by impregnating–spraying method. The complete rotary wheel dehumidification system was built to compare the dehumidification performance of MOF DW and commercially silica gel desiccant wheel (SG DW). The experimental results showed that increasing the rotation speed appropriately improves the utilization ratio of regenerative energy and dehumidification capacity of MOF DW at high ambient humidity ratio. The temperature rise at the inlet and outlet of MOF DW is lower than that of SG DW at low ambient humidity ratios, and the opposite is true at high ambient humidity ratios. In addition, the dehumidification capacity and coefficient of performance of the MOF DW increase by 40%–48% and 13%–19%, respectively, compared with those of the SG DW at the regeneration temperature of 50°C.
