실내공기질 관리 및 제어를 위한 학교 특성별 오염물질 현황 조사

Abstract

Purpose: The purpose of this study is to develop a control technology for air-clearing ventilation system considering the characteristics of school facilities, and to investigate, classify, compare, and analyze data that can consider general environment and school characteristics. Method: The current and characteristic of school facilities and the status of management of pollutants were investigated using government public data and the resulting environment variables were derived. The concentration of fine dust and carbon dioxide, which are the main causes of human activity and breathing, was selected as the main factors to analyze the correlation with general school facilities, such as locality, establishment date and coeducation status. Result: First, the standard classrooms in Korea are located in Seoul and Gyeonggi-do, with a total of 23 students or less. Second, the survey on the concentration of fine dust by age of school facility showed no significant difference, but in the case of carbon dioxide, the average concentration decreased as the age of school facility grew older. Since the age of school facility is related to the building’s confidential performance, it is considered that the building’s airtight performance is highly correlated with the concentration of carbon dioxide. Third, according to the analysis of indoor air quality according to the sex ratio of students, this ratio is also a major factor for indoor air quality, and it was deemed necessary to consider this when applying the air-cleaning ventilation system.
