机房空调实验室风道结构模拟分析及实验验证
Simulation Analysis and Experimental Validation of Air Duct Structure in Air-Conditioned Laboratory of Machine Room
摘要: 机房空调实验室内流场的均匀性直接影响采集数据的精确度，而送风风道出风直接影响实验室内流场均匀性。针对机房空调实验室送风风道提出5种结构(分别是方形送风结构、10˚/12˚/14˚倾斜挡板送风结构以及等风量连续斜板送风结构)，并建立几何模型进行数值模拟分析，选出对流场均匀性有较大改善的送风结构进行实验验证。结果表明：变截面积送风风道对流场的均匀性有一定的改善，尤其是对速度场的影响；14˚倾斜挡板送风结构的温度场和速度场的均匀性更好，在工程上易于实现，推荐使用该结构。
Abstract: The uniformity of the air flow field in the air-conditioning laboratory of the machine room directly affects the accuracy of the experiment data, and the air supply duct outlet directly affects the uni-formity of the air flow field in the laboratory. Five structures (the square air supply duct, the air duct supply 10˚, 12˚ and 14˚ inclined baffle respectively and the air supply duct with equal air volume continuous inclined plate) are proposed for the air supply ducts, the geometric models are established for numerical simulation analysis, and the air supply structure with greater im-provement on the uniformity of the flow field is selected for experimental verification. The results show that the variable cross-sectional area air duct can improve the uniformity of the air flow field, especially on the velocity field. The air supply duct with 14˚ inclined baffle is recommended because of the best uniformity of the temperature and velocity fields, which is realization in engineering application.
