Abstract Adverse health effects of particulate matters (PM) on the elderly, children, and people with pre-existing cardiovascular and respiratory diseases. have been reported to be more pronounced. The Korean government has enacted and managed special laws for vulnerable groups such as children and facilities they use. The outside PM flow into buildings along with air movement caused by infiltration. The PM is also generated by indoor activities such as cooking and cleaning. It can be transported to other rooms. The aim of this paper was to analyze PM concentration caused by the inflow of PM into the room when the front door was opened and the PM generated by cooking in a daycare center. The effect of installing an air curtain in a daycare center for blocking PM from outdoor and preventing transport from indoor PM generated by cooking was also analyzed by CONTAM simulation. Results showed that the air-curtain at the main entrance blocked the inflow of outdoor air and PM compared to the wind break room. When cooking in a cooking room, operating the range hood and air curtain at the same time showed the highest effect of removing PM. During cooking, the PM concentration in the cooking room did not directly affect the PM concentration in adjacent child care rooms. In the case of child care room adjacent to the cooking room, the outdoor air and PM flew into the child-care room according to the operation of the hood in the cooking room.
