海南某数据中心空调系统设计
Air conditioning system design for a data center in Hainan
摘要：
结合项目当地具体气候条件，综合对比多种空调系统方案，从节能效果、初投资、运行费用等各方面计算分析，找到适合本项目的空调系统节能设计。空调设计从系统架构特点出发，利用备用机组的制冷能力，结合磁悬浮机组部分负荷效率高的优点，实际运行时冷水机组全部运行，主机负载率为70%~80%，磁悬浮主机的COP可达15以上，配合冷却塔优化选型及新型空调末端可将PUE降到1.3以下。
Abstract：
Combining the specific local climate conditions of the project, this paper comprehensively compares various air conditioning system schemes, calculates and analyses the energy saving effect, initial investment, operating cost and other aspects, and finds the suitable energy saving design of the air conditioning system for this project. The air conditioning design starts from the characteristics of the system architecture, uses the refrigeration capacity of the standby unit, and combines the advantages of high partial load efficiency of the magnetic levitation chiller. In actual operation, the chillers fully operate. The load rate of the chiller is 70% to 80%, and the COP of the magnetic levitation chiller can reach above 15. With the optimized selection of cooling towers and the new air conditioning terminal, the PUE can be reduced to below 1.3.
