Effects of Environmental Adjustment Conditions of Nursery Facilities by CFD Analysis

- A Case Study of One-room Type Facility -

Abstract

In this study, CFD analysis was used to examine the effect of environmental adjustment acts on indoor air quality of nursery facility in urban area. As a result, it was confirmed that even with a ventilation volume of 30 m3/h per person, air was stagnant in the 2-year-old area separated by furniture. The use of ceiling fans was confirmed to have sufficient air circulation effect even in low operation. In addition, the window-opening ventilation had a significant effect on reducing the CO2 concentration, and the effect on the entire ventilation path was confirmed after 8 minutes. These results confirm the necessity of taking specific adjustment methods for space with stagnant air as the infection control measures.
