초록

The purpose of this study is to evaluate the location of the outlets in the mechanical ventilation system installed in apartment. We performed the numerical analysis to estimate the ventilation effectiveness and the indoor $CO_2$ concentration considering the occupants and the condition with inlet and outlet in each room. From the numerical results, modified location of the outlets is about 10% high than designed one with respect to the ventilation effectiveness when the occupants are not considered. But designed location of inlet and outlet in living room and kitchen is better than modified one with respect to the reduction of $CO_2$ concentration in the living room and kitchen with occupants. In case of our model, Air change per hour (0.7) is not enough to sustain the acceptable criteria of $CO_2$ concentration (1000ppm) in the room with the occupants
