Indoor particulate matter(PM) is a carcinogen and needs to be removed and managed. It is generally reduced and removed through ventilation and filtration. Owing to the recent occurrence of high-concentration fine dust and yellow dust in the atmosphere, however, it is difficult to expect the purification of indoor air through the simple introduction of the outside air. For residential buildings, in particular, they are highly dependent on natural ventilation but the lack of natural ventilation is worsening because concerns over the inflow of external pollutants are increasing. Therefore, this study designed and manufactured a window ventilation system that does not require a duct to improve the maintenance and management problems of general ventilation system, and constructed indoor PM concentration change data through performance evaluation.

In this study, we developed a window ventilation system based on the Internet (IoT) based technology. It can monitor indoor environment elements in real time and utilize Open API data through network connection. We also developed a window ventilation system that can automatically control the window ventilation system. The window ventilation system can be operated in three modes. Method: A mock-up test was conducted to evaluate the fine dust reduction performance of the window ventilation system. The experimental method was to compare the time to reduce the fine dust concentration to 100 μg / ㎥ or less, after generating 1,200 μg / ㎥ of fine dust in each chamber of the mock-up. Results: The performance of the window ventilation system in each mode was in the order of Mode 1> Mode 3> Mode 2.

The present study is a foundational study for performance improvements on isolation wards to prevent proliferation of secondary infection of infectious diseases such as SARS, H1N1, and MERS inside hospitals. Accordingly, the present study conducted an analysis of the effect of sealing mechanisms and filling of openings on ensuring air tightness performance in isolation wards as well as simulation on air currents in improved isolation wards. The study method is as follows: first, previous studies on aerial infection types and mechanisms were reviewed and the review results were utilized as basic data for analysis of the simulation of air currents. Second, national and international legislations and regulations in relation to isolation wards as well as case studies on developed nations were investigated in order to identify the problems in isolation wards in Korea and improvement plans. Third, construction and facility plans were compared and analyzed between general and isolation wards focusing on large general hospitals in Korea thereby conducting comparison and analysis on the performance and effects of air-tightness of general and isolation wards through simulations(CFD). Fourth, an analysis on air currents in isolation wards specified in mandatory legislation (draft) from the Ministry of Health and Welfare such as fulfillment of isolation ward requirements including negative pressure isolation wards, areas of ward and intensive care units, and ensuring separation distance between sickbeds was conducted. The study result showed that isolation wards had better air-tightness performance than that of general wards and parallel bed layout was better than serial bed layout in terms of aerial infection substance proliferation. In addition, when a separation distance between sickbeds was 2m or wider, the risk of aerial infection became significantly lower.

Ventilation is the most effective and easiest way to alleviate indoor air pollution. However, recently, it is an environment where natural ventilation is difficult because ambient air is polluted due to fine dust. In this paper, we propose a technology to improve the ventilation efficiency of window type ventilation system (patent name: Air Glide window), and the optimal (CFD) analysis was conducted to derive the outlet of the CFD. The results show that the window frame with 4 outlets is the most effective, but the two outlets are not significantly different from the two outlets. Therefore, it is effective to use two outlets in terms of maintenance.
