A Study on Estimation of Particle Penetration Load and Indoor Generation Load in Child Care Room

Abstract

Atmospheric particle concentration is increasing in Korea owing to industrialization in Korea and the influence of China. Outdoor particles can enter buildings through cracks or windows and affect the health of residents. Care rooms in childcare centers are meant for infants and children, who are more vulnerable to particles than adults; hence, indoor air quality management is necessary. Outdoor particles as well as the particles generated through children’s activities and indoor cooking should be considered for the assessment of indoor air quality of these places. Thus, particles that should be removed from such buildings comprise outdoor particles entering indoor and those generated indoor. The total concentration of these particles can be termed as particle load. Ventilation and air cleaning devices are effective in removing particle loads, and efficient indoor air quality management can be achieved by using devices of appropriate capacity and performance based on load estimation. Therefore, to estimate the particle load of care rooms, indoor air quality monitoring was conducted for one year, and the particle loads were estimated by analyzing the monitoring data.
