摘要
电费是数据中心运营的最大成本支出,电费成本占到共运行成本的60%以上,因此节约电能直接关系到企业利润。当前的大型数据中心通常会配套大型水箱的储能系统,利用波谷电价实现电费降低。但是利用水的显热变化进行储能,储能密度很低,而且水箱通常需要重达几千吨,建设和维护成本很高,水资源耗费大。基于此,笔者利用相变储能材料建设更为高效和低成本的储能系统。
Electricity cost accounts for more than 60%of the total running cost of IDC(Internet Data Center),so energy saving is directly related to the profits of enterprises.At present,large IDC usually support energy storage systems of large water tanks to reduce electricity tariffs.However,using sensible heat change of water for energy storage,the energy storage density is very low,so the water tank usually needs to weigh several thousand tons,construction and maintenance costs are expensive,and water resources consumption is high.Based on this,the authors want to achieve a more efficient and low-cost energy storage system using phase change materials.
