Data center cooling can be taken quite literally: regulating the temperature in the data center to reduce heat. The cooling system of a data center regulates various parameters to make the flow of heat and cooling as efficient as possible. That is necessary for a data center for energy efficiency reasons and to avoid the risk of server overheating. For this intensive cooling, a data center consumes a lot of electricity. At LCL, we are always looking for simple practices and modern technology to further sustainability of data center cooling.
