| Abstract |
This study evaluates the capability of natural ventilation facilities in an apartment house by using CFD analysis. Recently, the Ministry of Construction and Transportation decided that the the number of ventilation, 0.7th/h in apartment house with more than 100 household is mandatory and it is also required for the apartment house which has the natural ventilation facilities. CFD analysis is applied to the apartment house with 304 household in Seoul E-area and the natural ventilation performance in 40 py-unit is reported in this paper. Result are as following.1) When the natural ventilating openings are installed in the house which have 2 side ventilating openings at south and north, the natural ones play roles of intake and exhaustion. Therefore, it is necessary to equip double natural ventilating openings for the current standard regulation.2) Even though some of the units have natural ventilating openings of 3 sides (north/east/south in this research), which has a long enough natural ventilation path, the condition of 0.7th/h is not fully achieved because ventilation inflow and outflow parts are not separated. Hence, such a coexistence type not like cross ventilation type needs more investigation to calculate the exact amount of ventilation.Housing block arrangement and surrounding are as important as an apartment house unit's design to predict the performance of the natural ventilation equipment. They should be carefully considered to make natural ventilation facilities functional. |
