I have been asked many times over; what is data center temperature and humidity best practice? And have debated with my colleagues on why we should not be designing data centres at 18-20°CdB and 50% RH as we used to.
In data centres cooling designs, it’s not about the supply temperature, what really matters is the hot air containment and treatment. If you understand this, it will help you see my points and how you will be able to capitalise on these reasons to differentiate designs.
Here are the why for my design temperature and humidity
- will be able to save on running cost at an elevated supply air temperature and a higher temperature difference
- will be able to capitalise on an extended period of free cooling
- will be able to keep the cooling system as simple as I possibly can
- want to be environmentally friendly to the best of my ability using R718
- want to be compressor-less
- want to simplify maintenance
