针对某一中庭式商业建筑,先通过现场实验测试空调送风参数,以测试结果为依据建立验证数值模型,将模拟结果与实验结果进行对比分析,结果表明模型合理可靠。接着,在6次换气次数和19℃送风温度的情况下模拟研究了层式送风的气流组织特性及热舒适性,分析比较了两种送风方式下的温度场,PMV场。研究表明,在层式送风下,建筑工作区域温度覆盖较好,垂直温差缩小,热舒适性良好。
For a certain atrium commercial building, firstly, the air-conditioning parameters of air-conditioning were tested by field experiments. The numerical model was established based on the test results. The simulation results were compared with the experimental results. The results show that the model is reasonable and reliable. Then, the air flow characteristics and thermal comfort of the layered air supply system were simulated under 6 ventilation times and 19 ℃ air supply temperature. The temperature field and PMV field under the two ventilation modes were analyzed and compared. The research shows that under the layer air supply, the temperature in the construction work area covers better, the vertical temperature difference shrinks, and the thermal comfort is good.
