Huiyuan Cowins Technology Group Limited has achieved significant progress in the application of its phase-change material business in artificial intelligence (AI) data centers. The Group’s Zhongnong Meiya (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”. 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.
The Huailai Project was jointly developed by the Group, the U.K.-based Environmental Process Systems Limited, and Tsinghua University. 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%. 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.
