针对通风式双层皮幕墙(ventilated double skin facades,VDSF),用射线追踪法计算出幕墙系统在太阳辐射下的光学性能,然后将此光学模型与该文提出的VDSF类区域模型耦合,以长沙地区某外循环式VDSF为算例对其在夏季工况下的热工性能进行模拟。计算结果表明类区域模型计算方便且模拟结果全面,适用于对我国夏热冬冷地区VDSF进行性能评估与优化设计。
For the ventilated double skin facades (VDSF), the optical performance of curtain wall system under solar radiation was calculated by ray tracing method. Then, the optical model was coupled with the VDSF region model proposed in this paper. An extra-cyclic VDSF is an example of a simulation of its thermal performance under summer conditions. The calculation results show that the calculation of the class area model is convenient and the simulation results are comprehensive. It is suitable for the performance evaluation and optimization design of VDSF in hot summer and cold winter area in China.
