1, power utilization efficiency (PUE): PUE is the most commonly used indicator in energy consumption assessment of data centers, which is used to measure the energy efficiency of data centers. The calculation formula of PUE value is: total energy consumption of facilities (kWh) /IT energy consumption of IT equipment (kWh). The lower the ideal PUE value, the higher the energy efficiency of the data center.
2. Carbon emission: Carbon emission refers to the carbon dioxide emission generated during the operation of the data center. Low-carbon emissions indicate that data centers have little impact on the environment.
3. Energy efficiency ratio (cue): cue is an important indicator of energy consumption evaluation of refrigeration system in data center, and IT is the ratio of total energy consumption of refrigeration system to energy consumption of IT equipment. The lower the prompt value, the lower the energy consumption and the higher the efficiency of the refrigeration system.
4. Energy recovery rate (ER): Energy recovery rate refers to the ratio of the total energy recovered and reused in the cooling and heat dissipation process of the data center. The higher the er value, the better the energy recovery effect of the data center.
5. Load rate: Load rate refers to the ratio between the actual operating load and the design load of the data center. Higher load rate may lead to higher energy consumption in the data center, while lower load rate may mean insufficient energy utilization in the data center.
