Data Center Cooling Infrastructure

Interesting facts about data center cooling
The computer is probably most common device these days that is used in a number of offices as well as homes. There are also many facts associated with this revolutionary system that one needs to know in modern days. The system is used for filling, processing and storing different sorts of data. Cooling is an integral component of data center cooling, and a number of steps are advocated to maintain the necessary temperature in facilitating the running of your electronic equipment. At this moment a few overviews are suggested which will help you determine what the best route for your data center is.
Waste product- Heat
IT products consume a lot of electricity and leave behind heat as the waste product. As the data center happens to be an enclosed facility, if not provided an outlet this heat will damage electronic devices. Thus, you need to remove heat from your devices, and this is only possible by cooling. One of the problems faced is that removing something (even heat) requires energy. Besides infrastructure, it involves a cost in terms of operational and capital expenses. Though free cooling is not free as the name suggests, fewer infrastructure and less energy are required when you compare it to the traditional cooling methods.

Heat removal:
So what are the basic options for removing heat? The main aim of cooling is to remove heat from an internal environment, take it to outside, and in this process create a conducive environment for proper functioning. Two essential options are there in removing heat, by air or liquid. The major benefit of air cooling is that air is available everywhere. IT equipment is not hurt as one does not need to move it. On the other hand, liquid cooling can provide targeted cooling along with efficiency and effectiveness is increased. For example, it is possible to deliver chilled water on to a server rack, but liquid operated systems have some difficulties as well. Any form of liquid leaks is a threat to IT equipment, and transport of chilled water may shoot up the transportation costs. Because of the above reasons, liquid cooling is more costly than air cooling. But in the case of high-density applications, liquid cooling might be the only viable option.
Air cooling and liquid cooling designs:

Air cooling depends on use of computer air conditioning systems in converting warm air to cold air. It is available in a host of configurations, and their prime objective is to cool the room. To enhance the efficiency aspect, some designs provide hot and cold outlets to separate warm and cold air.
On the other hand, liquid cooling possesses greater budgetary and technical challenges. As it is an effective medium, it makes a necessity for high-end applications. The liquid is then transported to the data center, which is then directed to the room handler. As already stressed upon time and again, liquid cooling requires a lot of infrastructures. This is pertaining to the lines which carry the liquid and then possibly on to the racks.
Free cooling:
Also referred as water side or air side economization it is a known form of cooling, which has a tab on running compressors or chillers associated with traditional cooling approaches. With this form of cooling the infrastructure is not tampered, but it is put to minimum use.
It involves opening the mouth of the data centers and by this method, fresh air is used from outside to cool the equipment. Some difficulties are faced in this process like humidity variations.
The correct decision of a facility is dependent on a host of factors such as power density, cost aspect and so on. For high-density implementations, air cooling is a viable choice, and in the case of low budget implementations, air cooling with economization on air side is a better choice. Regardless of your budget considerations, air cooling will benefit you in the long run.
