摘要：基于数据中心空调冷通道参数,构建了逆流式露点间接蒸发冷却器的二维数值模型,以一次空气出口平均温度、湿球效率和制冷量作为冷却器冷却性能的评价指标,研究了在不同入口速度条件下,二次/一次风量比、通道长度和宽度对冷却器冷却性能的影响。结果表明:增加二次/一次风量比能够降低出口温度,提高湿球效率,但制冷量呈先增加后减小的趋势,最大值出现在风量比为0.2~0.3;随着通道长度、宽度的增加,通道接触面积增大,冷却器冷却性能提高。二次/一次风量比设定为0.3,入口速度设定为2.5 m/s,通道长度和宽度分别设定为1 m和0.2 m,能够在保证冷却器冷却性能的同时节约投资成本。
A two-dimensional numerical model of countercurrent dew point indirect evaporative cooler is constructed based on the parameters of air conditioning cooling channel in the data center.Taking the average temperature of primary air outlet,wet bulb efficiency and cooling capacity as the evaluation indexes of cooler cooling performance,the effects of the secondary/primary air volume ratio,channel length and width on cooler cooling performance under different inlet velocities are studied.The findings demonstrate that raising the secondary/primary air volume ratio can lower outlet temperature while raising wet bulb efficiency.However,the cooling capacity first increases and subsequently diminishes,with the maximum value appearing between 0.2 and 0.3.With the increase of channel length and width,the channel contact area increases and the cooling performance of the cooler improves.The secondary/primary air volume ratio is set to 0.3,the inlet speed is set to 2.5 m/s,and the channel length and width are set to 1 m and 0.2 m respectively,which can save the investment cost while ensuring the cooling performance of the cooler.
