摘　　要：为了进一步提高外墙的隔热性能,提出了一种在夹层通风墙体内设置管道,利用墙体保温及管道内水循环来实现通风降温的新型夹层通风墙体。通过试验分析了该通风墙体内外墙表面的温度、水温、通风墙进、出风口温度的变化。结果表明,该墙体可以大大减少室外传热,降低空调围护结构冷负荷,与传统墙体相比,节能率可达41.67%。In order to improve the insulation performance of walls, a new ventilation wall was put forward which sets pipes in the wall interlayer and achieves ventilation cooling by use of wall insulation and pipe water circulation. Through testing, the surface temperature of inside and outside wall, cooling water temperature, temperature change of inlet and outlet ventilation wall were and analyzed. The research shows that, the wall can greatly reduce the heat transfer outside the room, reduce the cooling load of air conditioning of building envelope. Compared with the traditional wall, energy-saving rate of new wall can reach 41.67%.
