摘　　要：现有的管式间接蒸发冷却技术分析,其机理研究有待深入。虽然数值技术省时省力,但针对管式间接蒸发冷却空调的数值方法并不完善。通过对兰州地区管式间接蒸发冷却空调试验测试数据的反复比对验证,本文得到了较为合理的三维全尺寸数值模型和方法,得出结构参数、介质参数等众因素对空调器的性能均有较大影响。The mechanism of the existing tubular indirect evaporative cooling technology needs further study.Although the numerical technology saves time and effort,the numerical method for the indirect evaporative cooling of air conditioning is not perfect.Through the repeated comparison and verification of experimental data of tubular indirect evaporative cooling air conditioning in Lanzhou area,a reasonable three-dimensional full-size numerical model and method are obtained,and it is concluded that structural parameters,medium parameters and other factors have a great influence on the performance of air conditioners.
