How To Keep The Data Centres Cool During The Summer Months

During the summer season, many data centres in UK show a significant increase in their energy consumption levels due to the hot climate. Fortunately, there are several countermeasures which can be enacted for saving energy and making data centres greener.

Be it small to medium enterprises or large organisations, majority of business firms in UK make elaborate usage of technology for running their trade properly. With the introduction of cloud services and platforms, most corporate firms have been able to reduce onsite infrastructure by storing their services, applications, software and other important information in data centres. Now, the thing that should concern us here the most is the impact of climate on these data centre facilities.

During the summer months, a substantial hike is generally observed in the energy consumption levels of data centres. About 5 percent of Europe’s energy bill every year is spent on attempts to keep the computers cool within these facilities. Fortunately, there are certain steps that companies can take for resolving these issues even when the sun is shining bright outside.

Let’s have a look at those steps in detail:

Cold and Hot Aisles :

In order to bring down the temperature of data centres during summer to the ambient level of 19 degrees Celsius, it is important to separate the hot and cold aisles from one another. This can be done by using the brute force method, which involves setting up of equipment and racks in a special way for directing cold air from sub floor plenum to SANs ( storage area networks ) and servers, and hot exhaust air to a certain area where CRACs (computer room air conditioners) can handle it.

Evaporative Chillers and Coolers :

Evaporative cooling (also known as adiabatic cooling) is a relatively new technology for keeping data centres cool during summer. Evaporative chillers and coolers use about 90 percent less power than traditional air conditioning units. They pull ambient warm air through fine mist or a soaked filter, which ultimately causes evaporation and brings down the temperature of the ambient air.

Filling The Gaps :

Sometimes gaps within the data centre can result in mixing of cold and hot air. This can again up the energy consumption levels and strip the facility of its eco-friendly factor despite of the presence of effective energy saving technology. Using data centre grommet to plug those gaps can ensure that cold and hot air go where they are supposed to.

Apart from the above mentioned strategies, there are several other methods which can be adopted for optimising the temperature within a data centre. However, one must have a sound idea of data centre cooling systems before using any of them.
