Previously, we wrote an introductory article on Data Center Cooling and Server Cooling. Under the Methods of Data Center Cooling, we mentioned about Free Cooling Methods for Data Centers and also promised you to write an separate article specifically on Free Cooling Methods for Data Centers. So, in this article we will discuss on various Free Cooling Methods for Data Centers.
Why we need Free Cooling Methods for Data Centers?
As we mentioned ago in different articles, the servers deploying Virtualization needs more intense cooling methods as because the components, specially the CPU gets overheated. More over, to save space, the Data Centers are now using slimmer Rack cabinet more than tower. So, in order to run the system properly, they need intense cooling.
The methods of traditional cooling is by usage of Air Conditioning Machine and circulating the cooled air using Fans. As our natural resources are limited and they are becoming more costly, to run a Data Center, the cost of electricity consumption becomes huge.
Free Cooling Methods for Data Centers allows to reduce the consumption of electricity, in some cases, Free Cooling Methods for Data Centers can even completely replace the methods of traditional cooling. So, both the recurrent cost and electricity consumption lessened.
Methods deployed for Free Cooling Methods for Data Centers
Free Cooling Methods are also known as Indirect Cooling Methods. In this article we will only list the methods used for Free Cooling of Data Centers. In next article, we will discuss where and which specific Free Cooling Methods are applicable for which situation.

Mechanical Cooling : Mechanical Cooling includes the usage of evaporator, circulation of water or might include usage of chemical like Ammonium Chloride. None of these methods are used now solely as Free Cooling Methods.
Partially Free Cooling along with Traditional Cooling Methods : Basically the mechanical methods of Free Cooling is enhanced by usage of external power. For example, if circulation of water is combined with a pump and the water in turn is cooled by a cooler system, these Free Cooling methods become very effective.
Pure Free Cooling : Deploying a Pure Free Cooling systems depends on geographical location (warmer countries will need more vigorous cooling), the total area of the Data Center (needs much more area) and a standby dependable power source.
