| 摘 要： | 对低温空调系统送风特性进行了研究,着重于低温送风空气流动状况及其对室内环境的影响.以某一典型的空调房间为研究目标,利用计算流体动力学(CFD),研究在低温送风条件下,室内气流组织的分布状况.通过建立合理的数学模型进行数值模拟,运用试验手段验证了模拟结果的可靠性,得到几种送风速度下的室内气流速度场与温度场的计算结果.经过分析,确定该空调室的送风速度范围与最佳值.最后得出每一种低温送风系统对应着一定的送风速度范围的结论.

| Abstract: | This paper presents an investigation in the diffusion performance and indoor of cold air distribution system.The flow conditions of cold air and its influence on the indoor environment were deeply discussed.Cold air discharge theory was used to analyze the diffusion performance and three important parameters were investigated,including the characteristic length,throw distance and separation distance.Regarding some typical air-conditional room as the object, this paper studies air-stream distribution in the ... |
