| 摘 要： | 以某一典型的空调办公室为研究对象,采用数值计算软件FLUENT模拟冬季室内设计温度分别为18℃和20℃时室内气流组织的分布状况,对比分析了在不同的室内设计温度下,达到相同的热舒适温度时,室内热负荷的变化,得出冬季室内设计温度为18℃时,采用大温差送风在消耗较少能量的情况下能达到最佳的热舒适温度,为其他相同或类似房间空调系统的选择和气流组织设计提供参考。

| Abstract: | By applying the numerical calculation software FLUENT, the paper simulates the air distributions when the room temperature is set at 18℃ and 20℃ in winter in a typical air conditioning office, and compares the changes in indoor thermal load to ensure the same thermal comfort at two different temperatures. It concludes that the optimum thermal comfort can be obtained when the room temperature is set at 18℃ in winter and the large temperature difference is adopted at the condition of less energy loss, thus offering suggestions for selecting an air-conditioning system and designing air distribution in the same or similar rooms. |
