This summer, we’ve been hard at work taking the high-tech cooling system in Data Hall 1 to its final specification, ready for full capacity.
Our entire facility follows a modular build methodology, which includes our unique evaporative cooling system. Everything is installed in A+B resilient pairs, which includes the cooling stack design employed at our London Central data centre. These act as the lungs of our data centre, breathing cool air into the overhead plenum.
Until now, we’ve had lot’s of headroom on the existing two stacks, comprised of four wet box units. Last summer, we rolled out a fully-integrated AC system to supplement this evaporative units, both for added operational resilience, as well as further cooling capacity should it be required.
Each of our stacks have intelligently controlled intake fans and active damping
We’ve now added the final two stacks to the system in Data Hall 1, taking our cooling capacity to maximum load. This further improves resilience on the system as a whole, and also provides a great deal of additional cooling as we continue to welcome new customers into our world-class data centre.
Our unique, highly-efficient cooling stack design
Part of this additional capacity includes the tripling of available extraction outlets, which gives us greater control over the pressure differential between hot and cold aisles.
At full speed we are now able to move 208,000 cubic metres of four-times filtered, climate controlled air through Data Hall 1 per hour. That’s a lot of air, creating a flow of freshly tempered air which refreshes hall-wide every 45 seconds (on average).
Our extraction capabilities have been heavily bolstered
We now have nine high-powered extraction fans
Further to this, we’ve also installed a new probe matrix overhead, meaning we now have temperature and humidity mapping capabilities across the entire data hall floor. This both feeds into the control systems which manage the cooling system, as well as our own monitoring and management systems for greater insights into heat and flow control.
Later this year, we’ll also be adding in further granular monitoring on the circuits which feed our cooling systems, which will allow us to see our PUE as it dynamically adjusts in real-time.
The cooling system in Data Hall 1 is now at full capacity, which is fantastic news as our ever-growing roster of clients continue to deploy new systems in our facilities.
