泰铂科技能效改造案例
Taybo Energy Efficiency Retrofit Case Study
应上海市某数据中心邀请，泰铂科技为其量身定制并实施了“类全天候双冷源”节能改造方案。项目改造前情况如下:
At the invitation of a Shanghai data center, Taybo customized and implemented a "quasi-24/7 dual-cooling-source" energy-saving retrofit solution for the facility.Pre-retrofit conditions are as follows:
项目位于上海市，为某数据中心冷源节能改造，在用机柜实际功率为3500kW。原有冷源形式为变频离心式冷水机组+冷却塔+板换，末端精密空调送风形式为下送风上回风形式，回风温度约27℃。
The project is located in Shanghai, involving an energy-saving retrofit of the cooling source for a data center, with the actual power of operational cabinets being 3,500 kW.The original cooling system consisted of variable-frequency centrifugal chillers + cooling towers + plate heat exchangers, while the precision air conditioning at the terminals adopted an underfloor air supply and overhead return air configuration, with a return air temperature of approximately 27°C.
本项目充分依托上海市丰富的自然冷源条件，旨在显著减少空调系统压缩机的全年运行时长，有效降低机房PUE，实现数据中心节能降碳目标。泰铂科技提供的是一套创新的数据中心节能解决方案，通过泰铂研发定制的高效换热器、双源CDU、先进控制系统与闭式冷却塔的协同工作，构建高效的自然冷却系统。核心改造措施如下：
This project fully leverages Shanghai's abundant natural cooling resources to significantly reduce annual operating hours of air conditioning compressors, effectively lower data center PUE, and achieve energy-saving and carbon reduction goals. Taybo provides an innovative energy-efficient solution for data centers, featuring a high-efficiency natural cooling system through the coordinated operation of Taybo's customized high-performance heat exchangers, dual-source CDUs, advanced control systems, and closed-circuit cooling towers.The core retrofit measures are as follows:
（1）新增自然冷源系统：在原有系统基础上，增加泰铂定制研发的冷却塔、高效换热设备及中央控制系统。
1.New Natural Cooling System:
A Taybo-customized cooling tower, high-efficiency heat exchange equipment, and central control system have been added to the existing infrastructure.
（2）双源协同与智能控制：
2.Dual-Source Synergy & Intelligent Control：
1）室外温度较低时（通常低于设定阈值），系统全部采用自然冷源（闭式冷却塔+换热器）供冷，关闭或最小化机械制冷。
When outdoor temperatures are low (typically below the set threshold), the system operates entirely on natural cooling sources (closed-circuit cooling towers + heat exchangers), shutting down or minimizing mechanical refrigeration.
2）室外温度较高，自然冷源不足以带走全部室内热量时，系统智能开启机械制冷，形成“机械制冷+自然冷源”的双冷源协同模式。
When outdoor temperatures rise and natural cooling sources cannot fully remove indoor heat load, the system intelligently activates mechanical refrigeration, creating a dual-source synergy mode combining"mechanical + natural cooling".
3）自然冷源系统采用1+1备份设计，全方位保障供冷连续性和系统稳定运行。
The natural cooling system features a 1+1 redundant configuration, ensuring comprehensive cooling continuity and system stability.
（3）无干扰改造：方案不改变数据中心原有制冷系统设备，改造期间保障不间断供冷，极大降低实施风险和对业务的影响。
3.Non-Disruptive Retrofit:
The solution preserves the existing cooling infrastructure while ensuring uninterrupted cooling during implementation, significantly reducing operational risks and business impact.
（4）冷负荷转移： 新增一套自然冷源系统，优先采用自然冷源供冷，大幅降低后续水冷机组的能耗负担。在适宜气候条件下，自然冷源系统可完全独立承担制冷任务。
4.Cooling Load Shifting:
A new natural cooling system will be added to prioritize free cooling, significantly reducing the energy load on the subsequent water-cooled chiller units. Under suitable climate conditions, the natural cooling system can fully and independently handle the cooling demand.
实施改造后，本项目年节约用电量为213万kWh，年节约费用170万元（电费单价0.8元/kWh）。
After the retrofit, the project achieves an annual electricity savings of 2.13 million kWh, resulting in costsavings of 1.7 million yuan per year (electricity price: 0.8 yuan/kWh).
