Power Usage Effectiveness (PUE) is a common metric used to measure data center energy efficiency. It represents the ratio of the total energy consumption of the entire data center to the energy consumption of IT equipment. The lower the PUE value, the higher the energy utilization efficiency usually is.

Is liquid cooling replacing air cooling?

Not completely. Air cooling remains suitable for many standard data centers, while liquid cooling is becoming the preferred option for high-density computing and AI workloads. Many facilities use both technologies together.

What coolant is used in liquid cooling systems?

The coolant depends on the cooling design. Common options include treated water, water-glycol mixtures, and specialized dielectric fluids for immersion cooling applications.

How does humidity affect data center cooling?

Yes. Excessive humidity may cause condensation, while low humidity increases the risk of static electricity. Proper humidity control is essential for reliable equipment operation.
