Data Center and Server Rooms

Data centers and server rooms contain computing equipment that generates heat. This heat needs to be removed unless for the proper functioning of the equipment. This is why cooling forms an important part of the data center environment, owing up to 40% of the electricity consumption of such a facility.

Enersion’s cooling forms an ideal application for data centers as it reduces electricity consumption by over 70% and therefore drastically reduces the operating cost, something that is critical to the competitive data center industry.

Heat Source

The heat for the chiller can be obtained from the following sources

Server Heat – Warm Water Cooling

A new trend in data center cooling is to use warm water for data center cooling. Although this sounds wrong, but recent developments have shown that circulating water at around 40 deg Celsius into the servers keeps it maintained at a temperature below which the efficiency reduces. This results in water leaving the data centers at around 60 deg Celsius which can then be sent to the chiller to produce cooling.

Warm water cooling has already been implemented by established companies where they use the resultant extracted heat for dehumidification. This is a more futuristic approach as identified by companies like IBM and Lenovo, which makes data centers even more efficient.

Combined Heat and Power

A Combined Heat and Power (CHP) unit is a device that uses fuel to produce heat and electricity. The fuel in most scenarios is natural gas. This is a cost effective method to obtain heating and power when compared to the electricity from the grid.

Enersion’s chiller can be integrated with a CHP unit, wherein it will utilize the heat from the CHP unit to produce cooling. This results in a trigeneration system, a system that provides locally produced power, heating and cooling in a much more cost effective method, capable of bringing down the energy costs of the facility to 90% depending on the natural gas and electricity rates at the location.
