The Technical Code for Liquid Cooling Systems in Data Centers (T/CECS 1722-2024), jointly led by the China Data Center Committee (CDCC) of Zhongshu Zhihui (Beijing) Information Technology Research Institute and Alibaba Cloud, and co-drafted by Hyperfusion Digital Technology, NARI Group, ZTE, GLP, Sugon, Inspur, and Accessen, was reviewed and approved by the Electronic Engineering Subcommittee of the relevant standards association. The code is scheduled to take effect on December 1, 2024. With extensive expertise in product development and application within the data center sector, Shanghai Accessen Co., Ltd. was invited to contribute to the drafting of this technical standard for liquid cooling systems.
With the rapid advancement of AI and intelligent computing, data centers are expanding in scale and increasing in computational density, leading to growing challenges related to energy consumption and heat dissipation at the cabinet level. Owing to its high efficiency, energy-saving performance, and environmental benefits, liquid cooling technology is increasingly recognized as a key thermal management solution for high-power data centers. The publication of the Technical Code for Liquid Cooling Systems in Data Centers addresses the absence of standardized guidance for liquid cooling applications. The code provides comprehensive specifications covering system design, installation, testing and commissioning, as well as operation and maintenance. It will contribute to the unification of technical requirements, encourage technological innovation, and serve as a reference framework for the development and deployment of new technologies and products, thereby fostering the advancement of the data center industry as a whole.
As a leading provider of thermal management solutions for data centers, Shanghai Accessen offers a comprehensive portfolio of products and integrated systems, including high-efficiency plate heat exchangers, hydraulic modules and Coolant Distribution Units (CDUs) for liquid cooling, as well as indoor and outdoor prefabricated integrated cooling stations.
Accessen’s liquid cooling distribution unit (ACDU) and hydraulic module combine the company’s extensive expertise in system integration with advanced liquid cooling technologies. Leveraging standardized design frameworks and modular architecture, these solutions enable flexible configurations and seamless scalability, significantly reducing data center cooling energy consumption and achieving PUE levels below 1.1. Even under the most demanding operational conditions, Accessen’s liquid cooling systems are capable of maintaining efficient and stable performance, ensuring high reliability and effectiveness of the data center cooling infrastructure.
In a pilot project involving a liquid cooling hydraulic module, Accessen implemented AI-based temperature control, utilizing comprehensive datasets from data center operations, IT infrastructure, and cloud services to train its optimization model. The company pioneered an energy efficiency optimization method tailored to cloud service workloads, effectively reducing the power usage effectiveness (PUE). This approach enabled the data center to achieve an average annual PUE as low as 1.1—well below industry benchmarks—resulting in energy savings of 1 billion kWh per year for every one million servers.
In addition to its liquid cooling distribution units and hydraulic modules, Accessen also offers indoor and outdoor prefabricated integrated cooling station solutions for heat exchange applications. In 2022, the company contributed to the development of the White Paper on High-Efficiency Integrated Cooling Stations for Data Centers. These solutions leverage advanced Building Information Modeling (BIM) principles to enable modular integration and factory-based prefabrication. With minimal on-site assembly required, this approach significantly shortens construction timelines while ensuring high-quality, rapid deployment. Accessen’s prefabricated cooling station solutions have been successfully implemented in numerous projects, including Phases I, II, and III of the GLP Data Center, Chengdi Lingang in Shanghai, the Zhenjiang Telecom retrofit, Dr. Peng in the Philippines, and China Mobile’s Southern Base.
The release and implementation of the Technical Code for Liquid Cooling Systems in Data Centers further supports the adoption of Accessen’s liquid cooling technologies—such as the ACDU unit, high-efficiency hydraulic modules, and indoor/outdoor prefabricated integrated cooling stations—within the data center industry. These solutions enable the high-quality and rapid deployment of liquid cooling systems, allowing users to enhance computing capacity while significantly reducing energy consumption. The standard helps guide the industry toward a more efficient, low-carbon, and resilient operational future.
