摘　　要：采用基于方程Modelica的建模方法对数据中心制冷机房系统进行了建模,评估了制冷机房冷却塔供冷技术的节能潜力。结果表明,制冷机房模型的主要参数模拟值与实测值误差为0.68%~5.3%。采用冷却塔供冷技术的机房全年制冷能效比EER可达6.3,并节省5.8%的耗电量。Chiller plants system model of data center is modeled by using equation-based Modelica language.The energy saving potential of chiller plants with tower cooling is evaluated.Results show that the error between the simulated and measured values of the main parameters of the chiller plant model is 0.68%~5.3%.Chiller plants with tower cooling can achieve energy efficiency ratio of 6.3 and save 5.8% of energy consumption.
