铝塑共挤门窗节能性能模拟研究
Simulation study on energy-saving performance of aluminum-plastic co-extruded window
摘要：
对铝塑共挤节能门窗的构造和节能性能进行了分析，与普通断桥铝合金门窗和塑钢门窗进行了对比。采用门窗热工性能计算软件MQMC计算了铝塑共挤型材配置不同门窗玻璃时的热工性能。以广州地区为例，对比分析了典型居住建筑与办公建筑采用铝塑共挤门窗和其他常用门窗的全年建筑能耗。结果表明：铝塑共挤门窗传热系数约为普通铝合金门窗的70%，断桥铝合金门窗的85%，与塑钢门窗的传热系数接近；与其他常用门窗相比，采用铝塑共挤门窗后可以显著降低居住建筑和办公建筑的全年建筑能耗。
Abstract：
Presents the construction and energy-saving performance of the aluminum-plastic co-extruded window, and compares with those of the traditional broken bridge aluminum and plastic window frames. Calculates the thermal properties of the aluminum-plastic co-extruded frames with different glasses using MQMC software. Taking Guangzhou region as an example, compares the annual energy consumptions of typical residential building and office building adopting the aluminum-plastic co-extruded window frame with those adopting other common window frames. The results show that the heat transfer coefficient of the frame is 70% of that of common aluminum window frame, 85% of that of the broken bridge aluminum window frame and similar to that of the plastic window frame. The aluminum-plastic co-extruded window frame is significantly contributing to the energy saving.
