某高层建筑设备平台高密度安装空调室外机的散热分析与优化

Heat Dissipation Analysis and Optimization of Outdoor Unit of High Density Air Conditioner Installed on a High-Rise Building Equipment Platform

为研究建筑设备平台的通风百叶对空调室外机散热的影响,结合具体工程,以某高层建筑为例,利用CFD软件模拟分析了夏季工况下某高层建筑设备平台内高层高密度安装的空调室外机的气流场和温度场,并根据原方案中存在的问题进行改善和优化。研究表明,设备平台前的遮挡物情况对空调室外机的散热具有关键的影响,对建筑设备平台的遮挡物进行合理优化是必要的。

In order to study the of ventilation louver of building equipment platform on the heat dissipation of air conditioning out door unit,taking a high-rise building as an example,the air flow field and temperature field of high density air conditioning outdoor unit installed in a high-rise building equipment platform in summer are simulated and analyzed by using CFD software,and the air flow field and temperature field are improved and optimized according to the problems existing in the original scheme.The research shows that the shielding in front of the equipment platform has a key impact on the heat dissipation of the outdoor air conditioning unit,and it is necessary to optimize the shield of the construction equipment platform reasonably.
