Interior circulation
系统原理
Principle
●夏季关闭通往屋内的风管，将双层封闭热通道内大部分热空气排出室外。
The system shuts down the air conduit to interior space in summer, and lets out most of hot air inside the double-layer sealed thermal chamber area into exterior space.
●冬季将温室效应蓄热的空气通过管道回路系统加热并传到室内，达到节能效果。
In winter, heat--retaining air in the greenhouse effect will be heated by conduit loop system and passed to interior space, and then energy-saving effect is achieved.
●系统构成——整体为单元式结构，外层采用封闭中空玻璃，内层为单层玻璃翻窗，中间空气层位置设置遮阳百叶;出风口与建筑空调系统相连。
System structure--unitized structure is adopted in this system. Outer layer utilizes sealed insulation glass, while inner layer utilizes pivot-hung single-glass window. Shading louver is installed between the two layers; the vent is joined with building air-conditioning system.
