Power consumption of industrial and commercial energy storage liquid cooling host

What is the total energy consumption of a liquid cooling data center?

The total energy consumption includes the energy consumptions of the cabinets, uninterruptible power supply (UPS), cooling system, lighting system, power transfer, and distribution system. The PUE of the liquid cooling data centers can usually be reduced to below 1.3 [6, 7].

Is indirect liquid cooling a viable solution for cabinet power density reduction?

Indirect liquid cooling is currently the main cooling method for the cabinet power density of 20 to 50 kW per cabinet. An integrated energy storage batteries (ESB) and waste heat-driven cooling/power generation system was proposed in this study for energy saving and operating cost reduction.

What is the PUE of a liquid cooling data center?

The PUE of the liquid cooling data centers can usually be reduced to below 1.3 [6, 7]. For places with low ambient temperatures, their PUE is supposed to be lower than this value for a higher cooling system efficiency and larger natural cooling time.

Does a high-density air-liquid hybrid cooled data center decrease PUE value?

The PUE analysis of a High-Density Air-Liquid Hybrid Cooled Data Center published by the American Society of Mechanical Engineers (ASME) studied the gradual transition from 100% air cooling to 25% air –75% liquid cooling. The study observed a decrease in PUE value with the increase in liquid cooling percentage.

What is the energy-saving ratio of waste heat-driven cooling system?

Due to the coupled energy-saving effect of the proposed system with waste heat-driven cooling, waste heat-driven power generation and UPS replacement with energy storage batteries, the energy-saving ratio of the proposed system reaches 26.2 %, which is higher than the other energy-saving methods. Table 2.

Why do liquid cooling data centers need energy-saving retrofitting?

However, for places with high ambient temperatures like Shenzhen, its liquid cooling PUE may still be higher than 1.3, and this is why the local liquid cooling data centers need energy-saving retrofitting to meet local policies for PUE in Shenzhen.
