| 요약2 | It is difficult to predict the air volume of the infiltration which is uncontrolled air entering through building envelope. In high-rise buildings, pressure differences of building envelope vary with building height, temperature differences between indoor and outdoor, and building characteristics. Especially, stack-induced huge pressure difference occurs in winter season. However, there is no consideration of stack effect in an conventional load calculation method for deciding capacity of HVAC system. The calculation result may have large difference to a actual building. The purpose of this paper is to suggest a simplified calculation method of infiltration by taking account of stack effect in a high-rise building in winter, considering the infiltration change according to vertical shaft plan. Affecting factors for infiltration in high-rise building were investigated and a simplified method of calculating infiltration was suggested. As a simulation result of 3 different vertical shaft type, it is shown that Neutral Pressure Level(NPL) and Thermal Draft Coefficient(TDC) vary from vertical shaft design plan. Accordingly, NPL height and TDC value are the factors that have a significant effect on infiltration. The infiltration calculation was performed by using the proposed simplified method, targeting single zone type and multiple zone type. |
