摘　　要：重庆某商场地下超市采用散流器上送风、百叶风口侧回风的空调方式。本文通过对该超市建立三维模型来研究其室内气流组织,分别采用现场实测方法和CFD数值模拟得到该超市内温度场和速度场分布。结果表明,数值结果与实测结果吻合良好,研究可为类似大空间多功能超市空调设计和运行提供建议。An air-conditioning mode of diffuser ceiling air supply and shutter side air return was adopted to control indoor environment for an underground supermarket in a large emporium in Chongqing.A 3D model was developed to study the airflow distribution of the supermarket.Both the experiment and CFD numerical simulation were adopted to investigate the distribution of temperature and velocity field.The results indicate that the simulated results were in good agreement with the measured ones.The present research results can provide suggestions for design and operation of air conditioning for other similar multi-function large-space supermarkets.
