중공사막 기반 소형 가습 시스템의 실험적 성능 평가

초록

Although the latent heat load is increasing, the results of annual indoor temperature and humidity analysis of passive houses with highinsulation performance showed that the indoor relative humidity increased in summer, but the indoor humidity satisfaction survey in winteralso showed that more than 85% of the respondents answered that they were dry. Although the load increased, it was analyzed that theindoor humidity was still low in winter. In the case of the existing humidifier used in winter, since water or steam is directly sprayed intothe air, many problems such as contamination of the air by water occurred. Therefore, in this study, a hollow fiber membrane compacthumidification system, a new humidification type for increasing indoor humidity, was proposed and its performance was experimentallyreviewed. As a result, it was confirmed that when 150 cmh, which is the air volume of the ventilation level, was supplied, the absolutehumidity increased by about 4.14 g/kg, and the relative humidity of the discharged air increased by 64%. It is judged that thehumidification system proposed in this study has a high energy advantage due to the humidification performance shown when general tapwater (20℃) is supplied without a separate heat source.
