多层住宅建筑空调室外机散热对上层设备的影响

Influence of condenser heat release on upper amounted units on a multi-storied residential building

利用CFD研究了多层建筑空调室外机散热对上层设备的影响 ,结果表明 ,热空气向上流动不仅与室外机的热释放效率有关 ,而且与室外机内的风机功率有关。下层设备运行对上层设备造成的影响有 :增加入口空气的上升速度和温度 ,前者导致上层设备内风机的效率降低 ,后者影响空调器的散热。

Using CFD studies the influence of heat release from the outside unit of an air conditioner on the upper located outside condenser unit on a multi-storied residential building. The result shows that the plume configuration has relation to the heat release efficiency of the condenser as well as the fan power of the air conditioner. The operation of the lower outside unit increases the upper one's air raising velocity and intake air temperature. The former reduces efficiency of the fan and the latter influences heat release of the air conditioner.
