摘要
数据中心通常采用闭式或开式蓄冷罐,确保在冷源切换或市电中断过程中,可以应急提供数据中心全部冷负荷需求,此种情况下蓄冷罐的容量相对较小;而本文搭建的水蓄冷空调系统设计方案,蓄冷罐容量除了考虑应急蓄冷外,同时考虑在峰谷电价不同的波段进行蓄冷、释冷,节省制冷系统运行费用,还可以满足制冷系统的冷却水补水需求,此种情况下蓄冷罐容量相对较大、控制逻辑更为复杂,可为其他数据中心蓄冷设计提供参考.
Abstract
Data centers usually use closed or open cold storage tanks to ensure that in the event of a cold source switch or power outage,all cold load requirements of the data center can be provided in an emergency manner.In such cases,the capacity of the cold storage tank is relatively small;The design scheme of the water storage cold air conditioning system constructed in this article not only considers emergency cold storage,but also considers cold storage and release in different frequency bands of peak and valley electricity prices,saving operating costs of the refrigeration system.It can also meet the cooling water replenishment needs of the refrigeration system.In this case,the capacity of the cold storage tank is relatively large and the control logic is more complex,which can provide reference for the cold storage design of other data centers.
