Review of the impact of liquid desiccant dehumidification on indoor air quality

Liquid desiccant dehumidification has received much attention in recent years due to its effectiveness in humidity control and great potential in energy saving of buildings. At the same time, indoor air quality (IAQ) problems associated with liquid desiccant dehumidification also aroused people's attention since IAQ has a great significance for human health and life. This paper focuses on the impact of liquid desiccant dehumidification on IAQ and reviews recent achievements and progress in this respect. The recent researches in this field are reviewed on: (1) The removal capability of liquid desiccant solution for volatile organic compounds. (2) The remove, filter, kill or deactivation effect of liquid desiccant solution on bacteria and virus. (3) The capture function of liquid desiccant dehumidification system for particulate matter. (4) The carryover of liquid desiccant.
