Huiyuan Cowins Technology’s Phase-Change Material Technology Lowers Data Center Cooling Costs Waste Heat Recovery Project Meets AI Industry Demand for Energy Conservation and Carbon Reduction
慧源同创科技集团有限公司（「慧源同创科技」，或连同附属公司统称「集团」；股份代号：1116.HK）欣然宣布，集团相变蓄能业务在人工智能（AI）数据中心应用领域取得重大进展。集团旗下中农美亚（怀来）零碳农业示范园项目（「怀来项目」），通过自主研发的相变蓄能（PCM）技术，以数据中心作为核心热源，成功构建「数据中心余热 – 设施农业 – 居民社区」三位一体的清洁供暖体系，不仅为中国北方地区季节性能源供需难题提供可复制的系统级解决方案，更助力绿色算力发展，为数据中心余热开辟高价值商业化出路，显著降低其散热成本与碳排放强度，为中国的「双碳」目标作出贡献。
Huiyuan Cowins Technology Group Limited (“Huiyuan Cowins Technology”, together with its subsidiaries, the “Group”; stock code: 1116.HK) is pleased to announce that the Group has achieved significant progress in the application of its phase-change material business in artificial intelligence (AI) data centers. The Group’s Zhongnong Mayer (Huailai) Zero-Carbon Agriculture Demonstration Park (“Huailai Project”), leveraging its self-developed phase-change materials (PCM) technology and taking data centers as the core heat source, has successfully built an integrated clean heating system of "data center waste heat – temperature-controlled farming – residential heating". This system offers a replicable solution to the seasonal energy supply-demand imbalance in northern China and advances the development of green computing power. By creating a high-value commercial pathway for data center waste heat, it significantly reduces cooling costs and lowers carbon emission intensity, contributing to China’s “dual carbon” goals.
怀来项目由集团联合英国Environmental Process Systems Limited公司及清华大学共同打造，是中国首个AI数据中心余热回收示范工程。该项目的核心突破在于集团自主研发的PCM技术，基于「优态盐」体系经纳米化改性重构，不仅拥有超长循环寿命，更能实现60%的节能率，相关成果已获多项发明专利。在怀来项目中，该技术体系展现出强大的场景适配能力，通过高效水源热泵系统，将数据中心在运行中持续产生的大量余热水提升至55℃可利用品位，再由AI智慧调度系统根据需求动态分配，在供暖高峰时直接输送至周边的农业温室与居民社区，低谷时则将余热与配套光伏电站的太阳能热量存储于相变蓄能装置，解决了北方冬季能源供需失衡的难题。据测算，该项目可为周边社区提供稳定清洁供暖，每年可为社区提供超过75,000GJ（吉焦耳）的热量，相当于约2,083万kWh（千瓦时），减少温室气体排放超过4,000吨二氧化碳，实现「变废为宝」的价值跃升。
The Huailai Project was jointly developed by the Group, the U.K.-based Environmental Process Systems Limited, and Tsinghua University. It is China’s first demonstration project for waste heat recovery from AI data centers. Its core breakthrough is the Group’s self-developed PCM technology, engineered through nanomodification of eutectic salts. This technology delivers an ultra-long cycle life and achieves energy savings of up to 60%, with multiple related invention patents granted. In the Huailai Project, the technology has shown strong adaptability across different scenarios. A high efficiency water source heat pump system upgrades large volumes of waste hot water generated during data center operations to a usable temperature of 55°C. An AI scheduling system then dynamically allocates this heat according to real-time demand. During peak heating periods, it supplies surrounding greenhouses and residential communities; during off peak periods, it stores surplus heat in phase-change energy storage devices together with solar heat from onsite photovoltaic stations. This effectively addresses wintertime energy imbalance in northern China. The project is expected to provide stable and clean heating to nearby communities, delivering over 75,000 GJ of heat annually (approximately 20.83 million kWh), and reducing greenhouse gas emissions by more than 4,000 tons of carbon dioxide, turning waste into a valuable resource.
商业化运营方面，怀来项目投入营运短短一年已实现收支平衡。目前，该项目已成为AI数据中心余热回收示范工程及技术母版，其成熟的解决方案可在全国各地数据中心区域复制推广，不仅能为周边社区、高端蔬果种植、食用菌培育等农业场景提供清洁能源支持，更能为区域碳达峰目标实现提供坚实保障。与此同时，集团另一重点布局 — 克拉玛依液冷数据中心示范项目已进入启动阶段。集团将紧跟全球技术发展趋势，进一步拓展PCM技术在数据中心领域的应用场景，精准解决AI行业高耗能、降碳减排的核心需求。
In commercial operation, the Huailai Project reached break-even within one year of commencement. It now serves as a demonstration project and a technical prototype for AI data center waste heat recovery. Its mature solution can be replicated across data centers in China, providing clean energy support for communities and agricultural applications such as premium fruit and vegetable cultivation and edible fungi breeding, while also supporting the achievement of regional carbon peaking goals. Meanwhile, the Group’s Karamay Liquid-Cooled Data Center Demonstration Project, another flagship project, has commenced. The Group will continue to align with global technological development trends, expand PCM applications in data centers, and address the core needs of the AI industry for lower energy consumption and carbon emissions.
当前，全球数字化进程加速推进，数据中心需求持续攀升。中国数据中心市场迅猛扩张，截至2025年10月，中国运营约450座数据中心。叠加「东数西算」工程、国家「十五五」规划中清洁能源转型加速，以及国家与地方各级政府推出对相变蓄能领域的补贴扶持政策，为集团数据中心余热回收业务开辟了广阔市场空间。未来，集团将持续推动数据中心余热高效转化，助力行业绿色升级。
As global digitalization accelerates, demand for data centers continues to rise. China’s data center market is also expanding rapidly, with approximately 450 facilities in operation as of October 2025. The "East-to-West Computing Resource Transfer" initiative, the accelerated clean energy transition under the national "15th Five-Year Plan", and multi-level government subsidies and policies for the PCM sector provide substantial market potential for the Group’s data center waste heat recovery business. In the future, the Group will continue to drive the efficient conversion of data center waste heat and contribute to the industry’s green transformation.
