   SEOUL, Sep. 21, 2026 ― LG Electronics (LG) launches its high-efficiency, highly reliable Air-Cooled Centrifugal Chiller (ACC) to meet the increasing cooling demands of AI data centers (AIDCs). The solution is designed to improve energy performance and maintain cooling continuity, further strengthening the company’s data center cooling portfolio. Available from 480 to 600 refrigeration tons per unit, the chiller can be configured for AIDCs with varying cooling requirements.¹   首尔，Sep. 21, 2026 ― LG电子（LG）推出高效、高可靠性风冷离心式冷水机组（ACC），以满足AI数据中心（AIDC）日益增长的冷却需求。该解决方案旨在提升能源性能并维持冷却连续性，进一步强化公司的数据中心冷却产品组合。该冷水机组单台制冷量覆盖480至600冷吨，可针对具有不同冷却需求的AIDC进行配置。¹

 High-Efficiency Cooling With Advanced Technologies
At the core of the new LG Air-Cooled Centrifugal Chiller is an oil-free magnetic bearing centrifugal compressor. By using magnetic force to suspend the rotating shaft without physical contact, the design eliminates the need for lubricating oil, reducing mechanical friction losses and improving compression performance. 先进技术实现高效冷却
新款LG风冷离心式冷水机组的核心是无油磁轴承离心式压缩机。该设计利用磁力使旋转轴悬浮且无物理接触，因此无需润滑油，减少了机械摩擦损失并提升了压缩性能。

  The chiller also incorporates refrigerant free-cooling technology, using cool outdoor air to lower the compressor cooling load. Unlike conventional free-cooling systems, it circulates refrigerant directly without an intermediate heat exchanger and does not require glycol, minimizing heat and pressure losses and simplifying maintenance. Based on LG’s internal simulation, refrigerant free-cooling can consume approximately 30 percent less energy annually than waterside free-cooling.² Moreover, LG’s series counter flow (SCF) technology helps maintain balanced operation by distributing the cooling load among the compressors.  该冷水机组还采用制冷剂自由冷却技术，利用室外冷空气降低压缩机冷负荷。与传统自由冷却系统不同，它直接循环制冷剂，无需中间换热器，也不需要乙二醇，可最大限度减少热损失和压力损失并简化维护。根据LG内部模拟，制冷剂自由冷却的年能耗比水侧自由冷却低约30%。²此外，LG的串联逆流（SCF）技术通过在各压缩机之间分配冷负荷，帮助维持均衡运行。

 Reliable Operation and Flexible Management
In addition to improving energy efficiency, the chiller is designed for consistent cooling and reliable AIDC operations. Its gap sensor, integrated into the magnetic bearing system, precisely detects the rotation axis to enable accurate control. Machine learning capabilities allow the chiller to adapt to operating patterns, helping reduce surges. During a power outage, an integrated uninterruptible power supply (UPS) provides emergency power, allowing the shaft to stop safely and lowering the potential for bearing damage. It also provides the fast recovery feature which restores cooling capacity within 3 minutes upon power restoration.³ 可靠运行与灵活管理
除提升能效外，该冷水机组的设计还可实现持续冷却和AIDC可靠运行。集成在磁轴承系统中的间隙传感器可精确检测旋转轴，从而实现精准控制。机器学习功能使冷水机组能够适应运行模式，帮助减少喘振。停电期间，集成式不间断电源（UPS）提供应急电力，使转轴安全停止，降低轴承损坏的可能性。它还具备快速恢复功能，可在供电恢复后3分钟内恢复制冷量。³

  LG is also strengthening its control and operation capabilities through Data Center Cooling Management (DCCM). The software enables integrated monitoring and data-driven control across complex cooling infrastructure, including CDU, Computer Room Air Handler (CRAH) and Air-cooled Centrifugal Chiller. DCCM supports continuous operation through early anomaly detection and virtual sensor-based diagnostics. It contributes to stronger risk management with predictive maintenance, while real-time optimization based on IT workloads can improve operational efficiency.   LG还通过数据中心制冷管理（DCCM）增强其控制和运营能力。该软件可对复杂制冷基础设施进行集成监控和数据驱动控制，包括CDU、计算机房空气处理器（CRAH）和风冷离心式冷水机组。DCCM通过早期异常检测和基于虚拟传感器的诊断支持连续运行。它借助预测性维护加强风险管理，而基于IT工作负载的实时优化则可提高运营效率。

 Proprietary Core Tech and Globally Validated Performance
LG’s proprietary Core Tech is central to the new chiller, encompassing key components such as compressors, motors, inverters and magnetic bearings. LG develops and manufactures these components in-house, then integrates them into complete systems to optimize overall performance, improve parts availability and shorten maintenance response times. 专有核心技术与经全球验证的性能
LG的专有Core Tech是这款新型冷水机组的核心，涵盖压缩机、电机、变频器和磁轴承等关键部件。LG自行开发并制造这些部件，然后将其集成到完整系统中，以优化整体性能、改善零部件供应并缩短维护响应时间。

  Moreover, the performance and reliability of LG chillers are validated through global certifications. LG chillers and testing facilities are certified in accordance with standards established by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), and LG’s air-cooled chillers have also received the AHRI Performance Award for nine consecutive years.  此外，LG冷水机组的性能和可靠性通过全球认证得到验证。LG冷水机组和测试设施均按照美国空调、供暖与制冷协会（AHRI）制定的标准获得认证，LG风冷冷水机组也连续九年荣获AHRI性能奖。

  LG chillers also enhance safety and reliability by meeting major global standards and certification requirements, including American Society of Mechanical Engineers (ASME) requirements for pressure vessels, Electrical Testing Laboratories (ETL) requirements for electrical safety in North America and Conformite Europeenne (CE) requirements covering safety, health and environmental standards in Europe.  LG冷水机组还通过满足全球主要标准和认证要求来提高安全性和可靠性，包括美国机械工程师学会（ASME）的压力容器要求、Electrical Testing Laboratories（ETL）的北美电气安全要求，以及涵盖欧洲安全、健康和环境标准的Conformite Europeenne（CE）要求。

  Further expanding its data center cooling solutions portfolio, LG will showcase its modular hydronic cooling solution at Data Centre World Asia 2026 (DCWA 2026), held September 29―30 at Marina Bay Sands in Singapore. The solution integrates key components, including chilled-water pumps and a Thermal Energy Storage (TES) buffer tank, into a standardized module. It also enables factory prefabrication and assembly to simplify on-site installation, while LG's prefabricated modular chiller design provides flexibility for fast and scalable deployment as AIDCs expand their capacity.  为进一步扩展数据中心制冷解决方案组合，LG将在2026年9月29日至30日于新加坡滨海湾金沙举行的2026年亚洲数据中心展（Data Centre World Asia 2026，DCWA 2026）上展示其模块化水系统制冷解决方案。该方案将冷水泵和热能储存（TES）缓冲水箱等关键部件集成到标准化模块中。它还支持工厂预制和组装，以简化现场安装；同时，LG的预制模块化冷水机组设计可在AIDC扩容时为快速、可扩展的部署提供灵活性。

  “As AI data centers become increasingly dense and heat-intensive, energy-efficient, reliable cooling is more critical than ever,” said James Lee, president of the LG ES Company. “With our Core Tech and data center cooling expertise, we will continue to expand our portfolio of solutions to meet these evolving requirements.”  “随着AI数据中心日益密集、热负荷不断增加，节能且可靠的制冷比以往任何时候都更加关键，”LG ES Company总裁James Lee表示。“凭借我们的Core Tech和数据中心制冷专业经验，我们将继续扩展解决方案组合，以满足这些不断演变的需求。”
