摘　　要：为了研究狭小凹槽内室外机的热环境,结合具体工程,运用CFD软件包中的FLUENT软件模拟分析了夏季工况下某住宅建筑狭小凹槽结构内2台室外机的气流场和温度场,并根据原方案中存在的散热问题提出了改善方案,优化了室外机热环境。研究表明,在狭小凹槽内安装多台室外机的情况下,有必要对室外机的热环境进行优化;改善方案比原方案平均降低室外机回风温度8℃左右,优化了室外机热环境,空调的制冷性能得到了提升。To study the thermal environment for outdoor units at narrow re-entrance, the flow field and velocity field of two outdoor units which are located at narrow re-entrant of a residential building are simulated by using FLUENT in the summer conditions, based on specific projects, lmproving solutions are provided to the heat dissipation issues, the thermal environment for outdoor units is optimized. It is necessary to optimize the thermal environment for outdoor units at narrow re-entrant when many sets of outdoor units are installed. Return air tempera- ture in the improving solution is 8℃, which is lower than that in original solution. Thermal environment for outdoor units is optimized and the cooling perfornmnce of air conditioning is improved.
