| Abstract |
The main objective of this study was to analyze the dehumidification performance of a centrifugal atomization-based liquid desiccant (LD) dehumidification system and compare energy performance. Dehumidification rate and effectiveness were evaluated to determine dehumidification performance. A parametric study was performed experimentally according to five variables: air temperature, air humidity ratio, solution temperature, solution concentration, and liquid-to-gas ratio. Cooling load was also compared with a packed-bed-based LD dehumidification system via experiment results and simulations. Results indicated that the dehumidification performance was improved at low solution temperature and high solution concentration. The dehumidification rate was also higher in hot and humid air than in a mild air condition. As liquid-to-gas ratio increased, dehumidification effectiveness also increased while dehumidification rate decreased. Finally, the proposed centrifugal atomization-based LD system could achieve the same dehumidification performance at a lower liquid-to-gas ratio than packed-bed-based LD system while saving 72% system cooling load. |
