Data Center Cooling Systems Efficiency for Less Energy and Cost


The data center cooling systems have crucial roles. Its most important role is to keep the energy bill low. The old cooling system was known to be causing energy bill sky rocketed. And the new modern system has successfully brought it back down. So when you question what was lacking from traditional cooling system, the answer is it wasted lots of money and energy. So, to build effective and efficient system there are few things you have to remember.

You must set the data center temperature right. It shouldn’t be too cold or hot. Instead, it has to be right. Besides the temperature that has to be right, you should also keep the humidity. It’s crucial in order to make sure the data center equipment can run safely and efficiently. The modern data center cooling systems enable the recycling of hot air from IT equipment into cooler air. This will improve the cooling efficiency. The bypass airflow reduction can actually help improving efficiency. This technique is often known as air flow management.


When it comes to the recommended temperature in ideal data center cooling systems, it is between 21 – 24°C. However, there are still some companies that waste a lot of money by setting the temperature below 21°C. There are also certain conditions that require the data center temperature to be set below minimal standard. But make sure that it doesn’t waste too much money. The refrigeration cost can increase when there is a mixture of exhausted and cold air in the same room. Therefore, it’s important to make sure all the elements are in balanced.


Therefore, you may want to apply some of the best recommendations to improve energy efficiency in the cooling system. The first thing to do is to measure the amount of energy the data centers use for the non-computing functions. This includes cooling. What’s particularly important is the effective airflow management. When there is effective containment, the risk of cold and hot air mixing can be reduced by data centers. In this case, you can copy what Google has done. Google recommends mixing both computational fluid dynamics and thermal modeling in order to formulate the most optimal strategy for the management of air flow. Another thing you can do is free cooling that has been proven to be effective in improving energy efficiency. Once you have done these two tricks, you have successfully created ideal data center cooling systems.
