Double circulation double skin curtain wall
System principle
By adopting compound ventilation mode, natural draught and mechanical ventilation can alternately operate under the different condition. The air outlet is opened in summer, and it let most of hot air inside double layer sealed thermal shaft vent out of the outdoor. In winter, the air outlet is shut down, by using the greenhouse effect to heat air of inter layer and increase temperature at internal surface, reaching energy-saving effect.

●System structure--whole system adopts unitized structure, outer layer adopts
sealed insulation glass, inner layer adopts single-glass pivot-hung window,
louver for adjusting light is in the middle; air outlet is applied blower.
●Heat preservation property--with admirable heat preservation and heat-
insulating property, k value of average heat transmission coefficient can reach
to 1.15W/m²K.
●Sound insulation property--with admirable sound insulation performance,
weighted noise insulation reaches to RW>42dB.
●Mixed ventilation--enting velocity can realize self-control, without relying on
building air-conditioning system, design construction is more agility.
