本軟件詳細描述
摘 要 用于住宅或辦公樓的空調室外機組通常安裝在側墻或屋頂上。由于空調室外冷凝機組釋放的熱量會使上部樓層周圍
環境空氣溫度升高，這將導致建筑有限空間內溫度的明顯升高，使環境不舒適度和空調機組的運行能耗增加。室外冷凝機組
離墻的安裝距離是影響機組效率的一個重要因素。 采用flunet軟件研究了高層住宅建筑第一層的室外冷凝機組離墻的安裝距
離對有限空間內流體的流動和溫度分布的影響，得出了不同空間尺寸下室外冷凝機組離墻安裝的最佳距離，為優化氣流分布
和提高機組效率提供了有效的技術支持，且對工程實踐具有重要的指導意義。

Abstract Air-conditioners used in residential or office buildings often have the outdoor condensing units installed at
the sidewalls or on the roofs. As a result of air-conditioner condensing units on the top floors suffering from an elevated
ambient air temperature due to the heat rejected from the condensing units below, it will cause temperature rise in the
con?ned space of a high-rise building, lead to uncomfortable thermal environment and deteriorative performance of the
air-conditioning system. Installation distance from the wall is an important factor that affects the performance of the
air-conditioning system. FLUENT software is applied to simulate the effect of the distance from the sidewall on the
fluid ?ow and temperature distribution in the con?ned space of the first- storey high-rise residential building. The
minimum recommended installation distance from the sidewall with the different dimensions of the con?ned space is
obtained. The effective technical data can be provided for optimizing air distribution and improving the efficiency of the
air-conditioning system, which is important to engineering practices.
