Indoor viral and fungal activity is affected by the concentration of moisture in the air. Since the concentration of viruses and fungi in the air directly affects the human body, it is necessary to maintain a specific humidity range through the air-conditioning system. The optimum humidity in the building is 40-60%, and it needs to be maintained regardless of the season. In winter, a separate humidification system is required to adjust the indoor humidity due to the dry outside air. However, since the conventional humidification system injects water or steam directly into the air, various problems, such as water pollution, occur. Therefore, this study proposed a new humidification method called the hollow-fiber membrane humidification system to increase indoor humidity, and the effect was experimentally evaluated. When 150 CMH (air volume of ventilation level) was supplied, the absolute humidity increased by about 4.14g/kg compared to the initial condition, and the relative humidity of the indoor supply air increased to about 64%.
