The energy efficiency test evaluates the energy utilization efficiency of the liquid cooling system under different load rates by measuring the energy efficiency ratio of the CDU, the system PUE value, and the power consumption ratio of auxiliary components, providing data support for system energy-saving optimization.

Test Background
Against the background of the "dual-carbon" strategy, the PUE (Power Usage Effectiveness) of data centers has become a core assessment indicator. The energy efficiency performance of the liquid cooling system directly determines the overall energy consumption level and operating costs of the data center.

FAQ
Q: How low can the PUE of a liquid cooling system be?
A: The PUE of a cold plate liquid cooling system can be as low as 1.06-1.25, and that of an immersion liquid cooling system can reach 1.03-1.10, far lower than the over 1.5 of an air-cooling system.
