区域冷却是指在集中的工厂中生产冷却水，并通过管道将其分配到多个建筑物，以冷却每个建筑物空调系统中的空气。本研究旨在研究风速和风向对冷却塔热性能的影响。此外，还对冷却塔排距、冷却塔风机转速的影响进行了模拟。利用区域冷却装置冷却塔的三维计算流体力学（CFD）模型，评估了不同环境条件和方向下的循环空气量。计算中采用了标准的κ-ε湍流模型和能量质量守恒方程。 目前的研究表明，平行于冷却塔组的吹风方向使再循环率最低，入口湿球温度增加最小。较低的风速和较高的冷却塔风机转速可以提高冷却塔的热性能。增加冷却塔组之间的距离可以降低再循环空气的百分比。距离超过冷却塔直径25倍时，再循环率仅为7.5%。这是首次研究冷却塔布置和风速对再循环流量百分比的影响。本研究的结果有助于冷却塔组的布置，并为冷却塔组相对于风向和周围环境的方向提供指导。 引用:2017年年度会议，加利福尼亚州长滩，会议论文

District cooling means producing cooled water in a centralized plant and distributing it in pipelines to a number of buildings to cool the air in each building's air conditioning system. This study set out to investigate the effect of the wind speed and direction on cooling towers thermal performance. Moreover, the distance between banks, and effect of cooling tower fan speed were also simulated. A three-dimensional Computational Fluid Dynamics (CFD) model of a district cooling plant cooling towers is utilized to assess the amount of recirculated air under different ambient conditions and orientations. The standard κ-ε turbulence model, energy and mass conservation equations were implemented in the calculation. The current study shows that blowing wind direction parallel to cooling towers bank gives the lowest recirculation rate with minimum increase in inlet wet bulb temperature. Lower wind speed and higher cooling tower fan velocity can enhance cooling tower thermal performance. Increasing the distance between the cooling tower banks can decrease the recirculated air percentage. Distances more than 25 times of the cooling tower diameter can have as low recirculation as only 7.5%. This is the first study to investigate the effect of cooling towers arrangement and wind speed on recirculating flow percentage. The results of this study can help in the arrangement of cooling towers banks and give guidelines for their orientation relative to wind direction and surroundings.
