Data centers are infrastructure resources that require a lot of energy, and with energy in technology comes heat. To keep data centre infrastructure efficient and operational, the temperature needs to be ambiante, which is down to the work of data center cooling systems.
The principle is simple, data center cooling systems work by removing excess heat from the air and replacing it with cooler air. The key to a good cooling system is the efficiency in the way the air circulates. More ventilation is more efficient, and the air will circulate easily therefore cooling the data center.
