Power Supply and Air Conditioning Technologies for Sustainable Telecommunication Infrastructure

摘要

Improving the energy efficiency of telecommunication equipment rooms and datacenters, which account for much of the power consumed in the NTT Group, is important for both the global environment and reducing electric power costs. This article describes recent discussions held by the Energy and Environment R&D (research and development) Committee and recent R&D on power supply and air conditioning technologies intended to achieve a sustainable telecommunication infrastructure.
