| 摘 要： | 为有效指导老旧小区建筑外窗节能改造,采用压差法针对严寒和寒冷地区106樘外窗进行了气密性实测。结果表明这些外窗的平均冷风渗透量为23.04m^3/(m^2·h),合格率仅为16.98%,大部分外窗达不到气密性要求;相对于木窗和钢窗,铝合金窗和塑钢窗能明显提升气密性;对于塑钢窗,单层玻璃与双层玻璃的气密性差别较小,平开塑钢窗的气密性明显优于推拉塑钢窗。

| Abstract: | To guide the energy-saving reconstruction of building exterior windows effectively,filed test and analysis for air tightness of exterior windows in severe cold and cold zones were undertaken.The results show that:the average air infiltration is 23.04m^3/(m^2·h)and the qualified rate is only 16.98%,Most of the windows can’t meet the requirement of air Tightness.The air tightness of aluminum alloy windows and plastic steel windows are better than the wood windows and steel windows evidently;The air tightness difference between the single glass-plastic steel windows and double glass-plastic steel windows is little and the air tightness of casement windows are better than sliding windows obviously. |
