某商业建筑凹槽空调室外机热环境CFD分析与优化
CFD analysis and optimization of thermal environment for outdoor unit of air conditioner at groove in a commercial building
摘要：
利用CFD计算软件对某商业建筑室外机凹槽的热环境进行了数值模拟，结合理论计算结果，对比分析了不同室外机外百叶间距和百叶倾角对凹槽内室外机的热环境的影响。结果表明，当百叶间距增大到80 mm时，可以基本消除室外机外百叶对空调出口气流的阻碍影响。同时，为了减少走廊下垂墙壁对气流的阻碍效果，室外机外百叶的下倾角应控制在10°左右。

Abstract：
Simulates the thermal environment of the groove of a commercial building using CFD. Combined with theoretical calculation results, analyses the impacts of different outdoor louver distance and louver angle on the thermal environment of an outdoor unit in the groove. The results show that the louver distance should be at least 80 mm to avoid flow resistance. Additionally, the louver angle should be around 10° to reduce the blocking effect.
