Data Center Energy Efficiency Construction Guidebook

Now is the time to consider energy-saving measures for data centers. We will explain it clearly with photos and illustrations!

This document introduces technologies for energy-saving construction in data centers. Updating air conditioning systems is very important, and by implementing server capping during this process, further energy savings can be achieved. However, when capping began to gain popularity over a decade ago, many server fans failed. Many may remember that capping led to failures. This is because sealing with cold aisle capping increases the pressure within the cold aisle. As a result, the fan rotation speed increased, which caused failures. This is also the reason why it was said that capping leads to more failures. To perform capping safely and without failures, it is necessary to adjust the pressure difference between the cold aisle and the hot aisle. The document includes various topics such as "Old data centers have poor air conditioning efficiency," "Capping that sends as much cold air as possible to servers," and "Effect verification through CFD analysis." It provides clear explanations with photos and illustrations. We encourage you to read it.
