What is this Free Cooling stuff?
Free Cooling is a highly efficient way of taking advantage of one of the main features of the UK climate. Whenever the outside temperature is less than the temperature of the water coming back from the data centre, we let the atmosphere do the work for us, we let the outside temperature cool the water. So for most days of the year (and pretty much every night) the chillers are doing very little.
Even if we lost ½ of the air con infrastructure, there is enough capacity to keep the rooms cool. We also run the fans from the UPS system to keep the air moving at all times, even in the event of a power failure. We are also cutting the fan speeds needed to pressurise the raised floor void by using baffles to direct cold air where it is needed. We can precisely control the conditions within the cold aisles using Thermal Imaging technology to map the airflow and temperature distribution to provide the best possible environment for your data.
