중공사막 가습 장치의 겨울철 가습 성능에 대한 실험적 분석

Abstract

t In this study, we proposed a hollow fiber membrane humidification module, a new humidification type to increase indoor humidity in winter, and conducted a parametric study of the hollow fiber membrane humidification module after experimentally examining its performance. In this study, an indirect humidification module in the form of a hollow fiber membrane was proposed. The hollow fiber membrane humidification module has a cylindrical structure and supplies water to the inside (tube side) of the hollow fiber membrane and indoor air to the outside (shell side) of the hollow fiber membrane. The discharge air is humidified through the movement of moisture to the outside. In this study, to examine the humidification performance of the hollow fiber membrane humidification module, a prototype specimen was produced using a cylindrical sample-type hollow fiber membrane, and the humidification performance according to operating variables was analyzed based on the winter indoor temperature condition. . As a result, it was confirmed that the absolute humidity of the air passing through the hollow fiber membrane humidification module showed a tendency to increase as the water temperature increased, but did not show a clear trend of increase or decrease as the water flow rate increased.
