基于CFD的高层建筑空调外机热环境优化研究

Optimization of Heat Environment of Air-Conditioning Outdoor Unit in High-rise Buildings based on CFD

本文以苏州金鸡湖CBD办公区某高层办公建筑为例,利用CFD软件,从空调室外机排风管道设置、外机面板格栅通透率(50%、75%)等方面对影响空调外机排风热环境的各种因素进行分析并对分析结果进行合理优化,发现影响空调外机热交换效果的隐患并提出相应解决方案,为类似的高层建筑空调外机布置,提供参考。

This article takes a Super high-rise office building in the CBD office area of Suzhou Jinji Lake as an example, using CFD software. The factors affecting the outdoor air conditioning and outdoor air exhaust heat environment are analyzed and the results are optimized from several aspects, such as the design of air exhaust pipes for air conditioning outdoor units, the permeability of 100 blades of the facade curtain wall(50%, 75%), and the outdoor air environment. The paper finds out the factors that affects the heat exchange effect of the air conditioner and puts forward the corresponding solution.
