地道风系统的数值模拟与应用研究
|
摘要
本文建立了地道风系统升(降)温过程的CFD模型,并使用文献中的测试数据对模型精确性进行了验证。在此基础上,结合一个旧建筑改造项目中暖通设计过程提出的利用地道风来预冷(热)新风方案,通过建立CFD模型,模拟了冬夏季不同室外环境温度下地道风系统的运行升(降)温效果,得出了夏季经地道处理的新风基本可以直接送入室内,但在冬季使用过程中建议由空调机组加热后再送入室内的结论。
The CFD model of tunnel air’s heating(cooling) process was built, and the CFD model was verified by test data in literature. Then, combining with a reconstruction project of existing building, a design was put forward using the tunnel air to heating(cooling) fresh air in HVAC design process. By built a CFD model, the operating effect of the tunnel air system under different outdoor environment temperature in winter and summer was simulated. It is concluded that tunnel air treatment basic can directly supply to the interior in the summer, but in winter, before the fresh air supply into interior need to reheating.
