Background

According to the development goals outlined in the Implementation Plan for Promoting Green and High-Quality Development of Data Centers and 5G and Other New Infrastructures to Meet Carbon Peak and Carbon Neutrality Targets, by 2025, data centers and 5G will basically form a green and intensive integrated operation pattern. The power usage efficiency and renewable energy utilization rate of data centers will be significantly improved. The average power usage efficiency of newly built large and ultra-large data centers nationwide will drop below 1.3, further reduced to below 1.25 in national hub nodes, with a green and low-carbon level reaching 4A or above. The overall utilization rate of national data centers has significantly improved, with the utilization rate of western data centers increasing from 30% to over 50%. The supply and demand of computing power between the eastern and western regions have become more balanced, and the energy efficiency of 5G base stations has improved by over 20%. Data centers have high requirements for the PUE energy efficiency of equipment rooms, and the selection of air conditioning systems needs to take into account different geographical locations and climate conditions. China's "East Data West Computing" project has officially been launched in full swing. By constructing a new computing power network system that integrates data centers, cloud computing, and big data, the computing power demand from the eastern region will be orderly guided to the western region, optimizing the layout of data center construction and promoting coordinated development between the eastern and western regions. Data centers and their supporting industrial chains will experience breakthrough growth, requiring more energy-efficient and high-performance air conditioning systems.

SINO KING Solution for Data Center Air Conditioning Systems

Considering the high sensible heat load and year-round cooling demand of data centers, SINO KING recommends a natural cooling chiller unit that can fully utilize natural resources. The unit integrates a compressor refrigeration system and a natural cooling system, with low cooling energy consumption year round, effectively reducing the overall cooling energy consumption of data centers. The unit has three cooling modes: compressor cooling mode, hybrid cooling mode, and full natural cooling mode. The cooling mode is intelligently switched by the PLC control system based on ambient temperature and chilled water temperature.
