Cooling Basics

As a datacenter or computer room owner you should check your expenses about your cooling requirements. On your computers whitepapers, every system has how much electricity uses. So be sure to check your total electricity expenses.
Once you find your total expense in kWatts, you should need to add computer rooms cooling requirements. As a best practice, you can add 400 btu per metresquare area in a average of 3,5 m. height. Ok?
Let's find your total requirement. Multiply your electricity requirement in kWatts for your servers by 3414 and add area multiplied by 400. This number will give you the exact BTU requirement.
As a best practice 59 kWatts cooling capacity system has an expense of 17 kWatts cooling and 5 kWatts for humidity organization. So for finding total electricity expense with cooling, you can assume that for each 59 kWatts server electricity expense you should add 22 kWatts cooling expense if you use CRAC.
We will talk about alternative ways to decrease cooling bills. Headlines will be:
- Hot air/Cold air aisle
- Usage of free cooling systems
- Exhausting hot air as it gets out of the systems
- Usage fresh air from outside if it is tempreature is less than inside
- Having underfloor airflow barriers
