摘　　要：通过WINDOW7.4软件模拟分析玻璃厚度、薄膜和中空层等因素对Low-E中空玻璃热工性能的影响。结果表明,玻璃厚度对系统热工性能影响很小,薄膜位置、中空层介质和厚度对Low-E中空玻璃热工性能具有显著影响,且不同中空层介质存在最佳厚度值,其中空气层最佳厚度为14mm,氩气层最佳厚度为12mm,氪气层最佳厚度为8mm。Based on the window simulation program WINDOW7.4,the influencing factors were simulated and analyzed respectively for glazing system,such as the glass thickness,the location of the coating and the type of insulating layer.The result shows that,the glass thickness has little effect on the thermal performance of glazing system while the location of the coating and the type of insulating layer have significant effects.Different insulating layer media has different optimal thickness,such as the air layer is 14 mm,the argon layer is 12 mm,and the krypton layer is 8mm.
