摘　　要：The performance of liquid desiccant dehumidification systems can be improved substantially by applying the ultrasonic atomization technology.However,considering the currently-high expense and extra power for the ultrasonic atomizers,it’s unclear if the ultzasonic atomization dehumidifying system(UADS)possesses good economic performance over the conventional packed-bed(PBD)systems.This paper conducted a comparative study on the economic performance between the UADS and PBD.An economic analysis model integrated with the empirical formulae was established while an office building located in Guangzhou,China was employed as the study case.The results indicate the UADS may fit best for buildings with deep-dehumidification needs but smaller-scale areas.The performance of liquid desiccant dehumidification systems can be improved substantially by applying the ultrasonic atomization technology.However,considering the currently-high expense and extra power for the ultrasonic atomizers,it’s unclear if the ultzasonic atomization dehumidifying system(UADS) possesses good economic performance over the conventional packed-bed(PBD)systems.This paper conducted a comparative study on the economic performance between the UADS and PBD.An economic analysis model integrated with the empirical formulae was established while an office building located in Guangzhou,China was employed as the study case.The results indicate the UADS may fit best for buildings with deep-dehumidification needs but smaller-scale areas.
