Data centre equipment generates heat which has to be removed. Traditional data centres rely on continued use of chillers which consume power, thus increasing carbon footprint and operating costs.
At our Hoddesdon data centre we have deployed the latest “free air cooling” that is up to 50% more energy efficient than traditional cooling. While we still use chillers to create cold air, free air cooling systems means we only do so when the outside ambient temperature is higher than our ideal data centre temperature. In normal operation we use fresh air from outside of the building, which we clean and condition (a very low energy task) and then use that “free air” to blow the warm air out of the data centre. As long as the temperature outside is lower than our ideal temperature, which in England is most of the time, our cool air is “free” – which has a direct benefit on the environment and on the price we need to charge for you for your electricity usage in the building. Our Power Usage Effectiveness factor (PUE) is 1.5, meaning that for every unit of energy consumed by customers’ equipment, we only use 0.5 of a unit for cooling and other purposes. So, direct free air cooling means lower energy costs for you and a lower carbon footprint for us.
As with power, we can customise cooling to include full 2N cooling where the very highest levels redundancy are required.
