I'm tackling a challenge in my small high-density server room where I need to cool it using only standard comfort air conditioning systems, like split or cassette units. Precision cooling solutions aren't an option right now.
Here are some key details:
- The room size is 3.9m x 4.1m x 2.6m,
- I have 3 to 4 racks with a depth of about 1200 mm,
- The total IT load is roughly 30kW, mainly from GPU-heavy computing, and it's expected to operate 24/7.
I need some practical advice, particularly considering these main questions:
1. Is it realistic to achieve adequate cooling with comfort AC units? Can they reliably handle around 30kW if set up properly?
2. What sensible cooling capacity can I expect from units advertised as 9kW, 10kW, or 12kW, since server rooms often deal with sensible heat loads?
3. What's the best airflow layout for a compact room? Should I go for a cold aisle/hot aisle setup, hot air extraction, or a ceiling return strategy?
4. How do I manage humidity and condensation risks with multiple AC units running continuously?
5. For redundancy, is it better to have 2 larger units, 3 medium units, or 4 smaller ones for a balance of uptime and thermal stability?
If this were your project, what cooling approach would you choose for about a 30kW load in a small room using only comfort AC systems? I want to ensure I overbuild now to avoid regrets later.

Considering your constraints, maybe try using 3 medium-sized units? This gives you a decent level of redundancy while still being manageable in that compact space. Don't forget to account for airflow; good circulation can really help with the heat from all those GPUs.
You could definitely try to mix and match a few comfort AC units, but I’d suggest consulting with a local HVAC specialist first to see what they've done in similar setups. They might have some practical recommendations to optimize your system.
In this case, why not just ask someone from a local HVAC company? They can offer direct advice tailored to your situation instead of guessing here.
It sounds a bit like you're setting yourself up for trouble! Using comfort cooling for high-density server loads might not hold up. I'd personally recommend looking into better HVAC options if you can, as it could save you a headache down the line.
Honestly, if jobs like this pay, just look for something else! It’s tough to handle a continuous 30kW with regular AC units, and you might hit a lot of snags.
Thanks for the tip! I’ll definitely consider that balance between unit size and airflow.
