高层建筑封闭室外空调台内通风状况分析

Analyses of Ventilation Situation in Closed Air-condition Balcony One High-rise Building

应用CFD数值模拟技术对某高层建筑的封闭空调台中温度场进行数值分析,对比不同空调室外机放置位置以及不同室外百叶叶片间距情况下,空调室外机进风口处的温度变化情况结果表明空调室外机距离开敞空间越近,室外百叶间距越大,越有利于室外机的散热,空调室外机周围的环境温度越低,越有利于提高空调室外机的性能通风百叶的设置是室外机布置方案中非常重要的一个因素。

The temperature field in closed air-condition balcony of one high-rise building was numerical simulated by using CFD（Computational Fluid Dynamics） method,and the temperature behavior at the air intake of the air condensing units was surveyed according to comparing different position of the air condensing units and different interval of the blades outdoor.It turned out that the nearer air condensing units and the bigger interval of the blades outdoor were to the benefit of the heat dissipation of the air condensing units.The lower of the environment temperature around the air condensing units,the better performance we could get.It＇s a key factor that the ventilating blade of the air condensing units.The general rain-proof blades have a severe impact on the environment temperature around the air condensing units.
