ABSTRACT Infiltration through windows accounts for a significant heat loss in buildings during winter, leading to the need to minimize uncontrolled air flow. Improvement of window air tightness is important for reducing heat loss by infiltration through windows. In this study, infiltration is measured for general sliding (GS), parallel sliding tilt (PST) and lift sliding (LS) windows according to ASTM E283, a standard for window infiltration measurement. Measured window infiltration data, pressure coefficients calculated with STAR-CCM+ and outdoor weather data of Seoul are used in CONTAM, a network based ventilation simulation program to estimate infiltration during winter season for three sliding window types and their locations in a building. The results show that infiltration is highest for east located general sliding type window, and lowest for west located parallel sliding tilt window. Monthly analysis shows that for an east located window, infiltration is highest during January and lowest during December.

关于冬季关闭机制及其在建筑物中位置的滑动窗渗透研究

摘要 通过窗户的渗透是冬季建筑物中大量热量损失的原因，因此需要最大限度地减少不受控制的气流。提高窗户的气密性对于减少通过窗户渗入的热量损失很重要。在这项研究中，根据 ASTM E283（窗户渗透测量的标准）测量一般滑动 (GS)、平行滑动倾斜 (PST) 和升降滑动 (LS) 窗户的渗透。测量的窗户渗透数据、使用 STAR-CCM+ 计算的压力系数和首尔的室外天气数据用于 CONTAM，CONTAM 是一种基于网络的通风模拟程序，用于估计冬季三种滑动窗户类型及其在建筑物中的位置的渗透。结果表明，东侧一般滑动式窗入渗率最高，和位于西侧的平行滑动倾斜窗口的最低值。月度分析表明，对于位于东部的窗口，1 月渗透率最高，12 月最低。
