Work item: L.1328 (ex L.WHR)
Subject/title: Specification for waste heat reuse in telecommunication rooms and data centers
Status: Consented on 2025-06-12 [Issued from previous study period]
Approval process: AAP
Type of work item: Recommendation
Version: New
Equivalent number: -
Timing: 2025 (Medium priority)
Liaison: ISO/IEC JTC 1/SC39
Supporting members: China Unicom, China, Huawei
Summary: In the face of the rapid growth in the size and power density of global telecommunication rooms and data centers, the heat generated by equipment is growing dramatically, and if this part of the waste heat can be reused, it will not only improve the energy efficiency of telecommunication rooms and data centers, but also reduce the energy consumption of other industries such as heating. Therefore, guiding the use of waste heat reuse technology will become the next key breakthrough direction for energy saving and carbon reduction. Based on this, this Recommendation proposes the " Specification for waste heat reuse in telecommunication rooms and data centers ", which can effectively promote the reduction of energy loss and improve the energy efficiency.
