| Abstract | This study aimed to optimize the liquid desiccant absorber based on the solution atomization. The Hybrid
Metaheuristic Algorithm (HMA) method was used to optimize the absorber size (i.e., width and height) and operating
conditions (i.e., inlet solution temperature, inlet solution concentration, and liquid-to-gas ratio). The optimal design
that can minimize the cooling load for dedicated outdoor air system (DOAS) is as follows: Width, height, temperature,
concentration, and liquid-to-gas ratio are 0.6 m, 0.7 m, 20.6°C, 0.264, and 0.515, respectively. Finally, the solution
atomization type absorber can reduce the solution cooling load by approximately 13% compared to a packbed type
absorber with the same dehumidification performance during the summer period. |
