Telecommunication carriers’ energy consumption is above 2% of whole society energy consumption according to statistics and different functional telecommunication buildings’ energy consumption are different. With development of telecommunication carriers’ full business’ strategy

there are many telecommunication buildings and data centers across the country

which means energy consumption is increasing year by year. Meanwhile air-conditioning systems’ energy consumption has huge ratio of telecommunication energy consumption. The article introduces new energy saving technology to renovate traditional air-side condensation system into water-side condensation system. It not only deals with bad working condition during summer period

but also gives design reference to construction and operation

which provides stable

effective and energy conservation environment for ICT equipment.
