上海中信广场自然通风性能实测
Field measurement of natural ventilation performance of Shanghai Zhongxin Square
摘要：
介绍了该建筑的自然通风设计、设计阶段对其自然通风性能的模拟计算和竣工后的实测。模拟计算结果表明，过渡季节室内通风换气次数可以达到0.8～3.1 h-1。实测结果表明，开启所有自然通风口时，室内换气次数可以达到1.0～5.6 h-1，基本上可以满足室内人员所需最低新风量的要求。测试结果与模拟计算结果接近，自然通风性能基本满足设计要求。
Abstract：
Presents the natural ventilation design for Shanghai Zhongxin Square, simulation of ventilation performance during the design phases and field measurements after the building completion. The simulation results show that air change rate of the calculated space can reach to 0.8 to 3.1 h-1 during transition season. The field measurement results show that indoor air change rate can reach to 1.0 to 5.6 h-1 when all natural ventilation openings are opened, which can basically meet the minimum fresh air requirement of indoor occupants. Results of the field measurements are close to simulation results. Natural ventilation performance functions well as design expected.
