  • 차량 또는 실내에서 사용되는 대부분의 공기청정기는 미세먼지(PM 또는 PM)를 필터만 이용해서 정화하기 때문에 일정 시간 사용하게 되면 필터를 교체해야 하고, 필터를 청소한다고 해도 점점 성능이 저하되어 교체만 한다. 이러한 점이 개선된 플라즈마 공기청정기의 경우 필터 공기청정기에 비해 소비전력이 크다는 문제가 있다. 본 논문에서는 기존 플라이백 컨버터를 이용한 플라즈마 구동이 아닌 단일 스위치 무손실 인버터(국민대 보유기슬)와 펄스 전원(맥동 전압) 인가를 통한 플라즈마 구동 방식을 제안하고, 기존 DBD 플라즈마 방식이 아닌 자력을 이용한 DBD 플라즈마 리액터의 사용을 제안한다. 그리고 실제 실험 및 측정을 통해 제안 방식의 실효성을 검증하였다.

  • The final goal of this research is to develop a botanical biofiltration system, which combines green interior, biofiltering, and automatic irrigation, which can purify indoor air pollutants according to indoor space and the size of biofilter. The biofilter used in this experiment was designed as an integral form of water metering pump, water tank, blower, humidifier, and multi-level planting space in order to be more suitable for indoor space utilization. This study was performed to compare indoor air quality between the space adjacent to a botanical biofilter and the space away from the biofilter (control) without generation of artificial indoor air pollutants, and to evaluate plant growth depending on multiple floors within the biofilter. Each concentration of indoor air pollutants such as TVOCs, monoxide, and dioxide in the space treated with the biofilter was lower than that of control. Dracaena sanderiana ‘Vitoria’ and Epipremnum aureum ‘N Joy’ also showed normal growth responses regardless of multiple floors within the biofilter. Hence, it was confirmed that the wall-typed botanical biofilter suitable for indoor plants was effective for indoor air purification.

  • 우리나라는 국토면적의 65%가 산으로, 이 삼림은 우리에게 많은 자원을 공급해 주고 있다. 삼림은 물을 저장하는 탱크역할을 해 홍수를 막아주고 오염된 빗물과 공기도 정화해주고 있으며 목재를 공급해 주고 있어 연간 34조원에 달하는 해택을 우리에게 주고 있다. 그래서 우리는 산에 나무를 심고 인내를 갖고 정성들여 가꾸는 정신을 가져야 하겠다.

  • ln this paper, flowfields inside the various rooms have been investigated. A storage room, a liv-ingroom with a kitchen in an apartment, and a hospital room are considered in the present calculations. In all cases, it was found that the average of air change rate is. similar to that of perfect mixing assumption and the location of air purifier has little effects on the average air change rate. Detailed local air concentrations show that there are regions where air is not quite purified because of non-uniform circulation of air flow. The location of air purifier has great effects on this behavior.

  • This study is a study on the implementation and operation of smart air cleaning system to improve indoor air quality. Recently, the problem of indoor air quality is getting serious due to various environmental factors. In this study, to improve the problems of indoor air quality, we implement an air cleaning system using IoT sensor. In particular, we proposed a system that can measure air pollution in real time and change different air flow paths according to pollution level. Through this, we examined efficient air quality improvement, extension of filter life, and system energy reduction. In addition, the main functions of the indoor air quality improvement system were constructed and prototypes were manufactured to confirm the operability. Finally, the utility of fine dust resolution through the implementation of the indoor air quality improvement system was examined.
