Summary:
|
This Recommendation addresses the critical need for energy-efficient cooling solutions in base stations amid rising power demands and climate goals. It specifies and implementation guidelines for DC dual-cooling source air conditioning systems utilizing DC compressor and heat pipe, which combine mechanical refrigeration and natural cooling technologies. It introduced a strategy for adaptive operation across multiple cooling modes (mechanical, natural, dual-cooling source), with prioritization of natural cooling to minimize energy consumption and carbon emissions. The equipment features native compatibility with DC power sources, allowing it to be directly powered by backup batteries and photovoltaic energy, while enhanced reliability during grid outages. The recommendation also specifies several typical application scenarios, such as the mission critical base stations, PV integrated base stations, etc.
The document aims to standardize the deployment of these systems, supporting global efforts to reduce operational costs and environmental impact in telecommunications networks.
