With the digitization and networking of business operations, data centers (IDC) have become the core facilities supporting critical business operations and storing important data. However, the high energy consumption of IDCs has become increasingly prominent, especially the power consumption of UPS (uninterruptible power supply) and air conditioning systems, which account for the majority of total energy consumption. According to statistics, 87% of the power consumption of telecom operators comes from base stations and computer rooms, while the power consumption of IDC computer rooms even exceeds 80% of the total power consumption of the building. Therefore, how to effectively reduce the energy consumption of IDC computer rooms has become an important issue for enterprises to achieve energy conservation and emission reduction.

High Energy Consumption Challenges in IDC Computer Rooms

The high energy consumption of IDC computer rooms mainly comes from two aspects:

UPS Systems: To ensure the stable operation of data equipment, IDC computer rooms require highly available power supply systems, but redundant UPS equipment reduces operational efficiency and increases energy consumption

Air Conditioning Systems: As the power density of servers increases, the heat generation in computer rooms rises sharply, leading to a corresponding increase in the energy consumption of air conditioning systems.

Blindly reducing the redundancy of UPS and air conditioning systems may affect the stable operation of computer rooms. Therefore, energy saving must be achieved while ensuring safety.

Six Energy-Saving Principles for Data Centers

The following are six proven energy-saving principles applicable to both new computer room construction and existing facility upgrades:

Choose Low-Energy-Consumption Equipment

The power consumption of data equipment directly affects the energy consumption of UPS and air conditioning systems. Selecting low-power servers and storage equipment can reduce energy consumption at the source. For example, reducing equipment power consumption by 100W can decrease air conditioning cooling energy consumption by 120W.
Optimize Power Supply Solutions

Implement tiered power supply based on the importance of equipment to avoid excessive redundancy. For example, non-critical equipment can use lower-availability power supply solutions, thereby reducing UPS load and energy consumption.
Adopt High-Efficiency Cooling Technologies
Utilize natural cooling sources (such as cold air in winter) or high-efficiency refrigerants to significantly reduce the energy consumption of air conditioning systems. For example, northern regions can use outdoor cold air for indirect cooling.
Rational Layout of Computer Rooms and Equipment

Optimize equipment layout and airflow ventilation to avoid hot spots. For example, use hot and cold aisle containment to improve cooling efficiency.
Use Specialized Cooling Solutions for High-Density Equipment

For high-power-density equipment (such as blade servers), adopt liquid cooling or specialized cooling cabinets to avoid excessively low temperatures in the entire computer room.
Enhance Computer Room Sealing and Insulation

Improve the sealing and insulation of computer rooms to reduce energy loss. For example, use insulation materials for walls and ceilings, especially in high-temperature regions.

By following the above six energy-saving principles, enterprises can significantly reduce energy consumption and operating costs while ensuring the safe operation of IDC computer rooms. Whether building new facilities or upgrading existing ones, these principles provide practical solutions. Take action now to optimize your data center's energy efficiency and contribute to your enterprise's sustainable development!
