自然通风在于家堡地下交通枢纽设计中的应用
|
摘要
针对于家堡地下交通枢纽的特点,利用CFD模拟分析了过渡季半地下空间利用自然通风进行换气的可行性。结果表明:过渡季合理利用自然通风可以有效排除半地下站房内部的热量,保证环境舒适并减少通风空调系统能耗;合理布置天窗及出入口对于自然通风换气排热效果显著,过渡季主导风向上设置出入口有利于风压的利用,顶部天窗有利于热压的利用,且对自然通风效果影响显著。
In view of the characteristics of Yujiapu underground transportation hub, simulates and analyses the feasibility of natural ventilation in semi-underground space during transition season by CFD. The results show that reasonable natural ventilation in transition season can effectively reject the heat inside the semi-underground station room, ensuring the comfortable environment and reducing the energy consumption of the ventilation and air conditioning system. Reasonable arrangement of skylights, entrances and exits has a significant effect on natural ventilation and heat removal. In the transition season, setting entrances and exits on the dominant wind direction is conducive to the utilization of wind pressure, and the top skylight is conducive to the utilization of heat pressure and has the most significant effect on natural ventilation.
