APC: Data center easy to optimize efficiency improvement there's a coup.

APC provides you with a http://www.aliyun.com/zixun/aggregation/15149.html "> Integration System based on the following principles, which can greatly improve the efficiency of your data center:

Power and cooling equipment not currently in use should not be powered.

Minimize system over planning so that the device can operate within the optimum range of its efficiency curve.

Power, cooling, and lighting devices should use the latest technology to minimize power consumption.

For subsystems that must run below the rated power (to support redundancy), the efficiency of the partial load runtime should be optimized, not the full load efficiency of the device.

Capacity management tools should be used to minimize the "idle capacity" in the datacenter and to install as many IT devices as possible for all power and cooling systems, with a view to enabling the system to run near the highest point of its efficiency curve.

The best all-in-one physical configuration should be derived from the data center system and not associated with the features of the rooms that are installed. For example, the inter-row cooling should be considered with the IT cabinet, regardless of the engine room cooling.

The system should be equipped with monitoring devices in order to display and early warning in the presence of undesirable power consumption, so as to facilitate quick resolution of the problem by staff.

The system should contain installation and running tools and rules to maximize operational efficiency and minimize or eliminate the possibility of poor configuration or installation.

Shows a commercially integrated data center system that conforms to the above principles.

The power consumption of data center system is reduced by 40% compared with traditional design, and the reduced loss is classified in detail.

Improved system efficiency can significantly reduce electricity tariffs. According to the IT load of 1MW, the electricity cost of 0.10 dollars per degree, this system can save about 9 million dollars of electricity bill in ten years.

The above improvements are based on data centers with the following configurations:

2MW Design Capacity

1MW actual IT Load

Overall power and cooling infrastructure is 2MW, installed and powered on

Dual power supply from line inlet to load

Using N Air processor

Cooling water System

Average power density per rack 7kW

Hot Channel/Cold channel IT rack layout

The efficiency curve for all equipment comes from real supplier data

Another strategy to improve data center efficiency is to take advantage of cool outdoor temperatures in some areas to increase the efficiency of cooling systems with "More economical cooling mode" or "free cooling". These methods usually increase the cost of the data center, but they have payback periods (depending on the outdoor temperature and humidity conditions). "Free cooling" is a complement to the method described in this article-to use cool outdoor air to reduce the power consumption of cooling, thereby improving data center efficiency.
