Air Flow Measurement and Management for Improving Cooling and Energy Efficiency in Raised-Floor Data Centers: A Survey

Research progress and development trend of cross-layer energy efficiency optimization in data centers

“…影响制冷系统能效的因素众多, 除单独优化机柜间温度分布外, 部分研究者也考虑将影响制冷系 统能效的因素整合在一起构建制冷代价优化模型 [15,18,20,24,25,32] , 通过负载调度的方式从整体上提升 数据中心制冷系统能效. Yeo 等 [33] 对现代数据中心广泛使用的 HVAC 系统的能耗组成进行了剖析, 发现主要的耗能部件是冷却装置 (chiller) 以及驱动冷气为 CPU 等热源散热的风扇 (fan), 且二者的功 耗占总 HVAC 系统的总功耗比均为 39%.…”

Integrating Pre-Cooling of Data Center operated with Renewable Energies

“…First, the thermal behavior of the data center over time was simulated according to the equations previously described. By default, the algorithm has nothing to decide: indoor temperature and heat pump state are determined at each iteration based on the values of the model variables at the previous iteration (Equations (4) and 8). Figure 1 exhibits for illustration a standard output where the cooling strategy is the basic TCL.…”

“…On the issue of data centers, which are large consumers of electricity, researchers have been studying energy efficiency for more than a decade. Authors surveyed energy efficient techniques for cloud data centers [1], [2], multi-tenant data centers [3], some focusing on cooling [4] to cite a few. According to the 2017 Greenpeace report [5], more and more IT companies are committed to a 100% renewable supply.…”

A detailed Study on Data Centre Energy Efficiency and Efficient Cooling Techniques

“…In this paper, the authors tried to present the capability and of importance demand response and energy system integration that becomes a great method for changing the taxation and electricity market design and also develop the future policies, policy coordination. Jianxiong Wan et.al [37] tried to present a survey report on the technique of current air flow management to betterment the effectiveness of energy and cooling. The article first revised the current measurement methodologies and various instruments that are already giving the impact on the cooling performance on the basis of the inputs of thermal measurement data and then this article depicted the techniques of air flow management for several cooling components with air flow cycle.…”
