Summary

This study aims to analyze the theoretical dehumidification effectiveness at different liquid-to-gas ratios and NTU values to demonstrate the feasibility of the mist-atomization dehumidifier. The detailed effectiveness-NTU model was used to estimate the dehumidification effectiveness of both the proposed mist-atomization dehumidifier and the reference packed-bed dehumidifier. The main results of this study is that the effectiveness of dehumidification improves, as NTU and liquid-to-gas ratio increase, and the maximum theoretical dehumidification effectiveness is 1.0 when the liquid-to-gas ratio is greater than 0.2. In the case of 0.2 liquid-to-gas ratio, the maximum effectiveness was 0.42. Based on the theoretical dehumidification effectiveness according to the NTU, the liquid-to-gas ratio of 0.6 and 0.8 was required in the proposed and reference dehumidifier, respectively to achieve the target dehumidification effectiveness. This suggests that the proposed dehumidifier can achieve comparable dehumidification performance to the reference dehumidifier using a smaller liquid-to-gas ratio.
