stand by computers in server room

Samsung and Frigidaire are the big players here.

HVAC performance is just as much about the skill of the person installing and maintaining it as it is the brand of the unit. HVACs are suppose to be checked every 6 months. a lot of failures are from low coolant levels over time causing failure.

Carrier? After being in the Carrier Dome which they cannot air condition, I've never felt good about them. If they can't cool their own facility, why would I trust them? Never use someone that doesn't eat their own dog food.
Superisingly I've had better results from the cheaper brands like Heil/Goodman than I have from expensive brands like Trane, Carrier, Lennox, York etc.

Our units were Hitachi.

Is it weird that I don't think of any of those as "good" or high end brands but as cheap American made stuff? AC is not something that American made sounds like quality to me outside of Frigidaire. Those are feel like consumer brands as opposed to the big enterprise makers.

Trane is probably one of the most popular in american enterprises. Mostly because people get sold on the Tracer Summit automation rather than how the HVAC functions itself. Luckily we didn't.

I'm pretty sure we use Liebert here. No opinions one way or the other.

I live in the third world too, all remote controlled AC here, too. In the US, that's unheard of (at least to me.)
Most other countries make more use of using Mini-split HVAC units. Here in the US Central HVAC is more common even if it uses more energy (and you have to heat/cool everything instead of just certain rooms like you can with mini-splits, and no duct to lose the temperature in a mini split)
Quite common in Mexico as well, we are using Mirage currently.

Liebert Makes HVAC? I think ours datacenter one might be too. Never looked at it much it's in a separate room. I do know it's not a normal HVAC in the sense it does not only ducts. It uses water pipes to heat/cool the air. We do have very large Liebert NX 3 phase UPSes though. They are nice.

I'm 90% sure it they are big HVAC units. I will have to look again. We have an APC Symmetra Power distribution system for our datacenter which works really well. Even triggers the generator to cut on when the main feed loses power.

Yeah ours is very big but I don't look at it nor the UPS systems much. We have a team to handle that. Our Distribution cuts over to genny automatically and the UPS is always online (battery filtered). Sadly no one bought the web card for the UPS or power distro so it doesn't do graceful shutdowns but, it would be rare to lose multiple power companies, generators and UPS. Though it could happen.

Independent of the failure issue, I wouldn't store spare machines in the server room itself. That means unnecessary clutter, as well as danger of bumping something when moving those desktops around. Better to have a separate room for spare equipment, with a workbench and tools.
-
@Nic good point. Don't treat the server room like a storage closet!
-
I agree that that sounds really cold. You must be running the AC really hard to keep it that cold. Try inching it up, don't make a bit leap. Little bits, test the servers, inch it up some more.

Did you manage to raise the temperature? Did it reduce the condensation problems?

no actually, the remote controller is still missing, and for the computer, i think we will buy a new one because it looks like the motherboard was damaged, and the computer is 3 years old so it is not a good idea to buy a motherboard, it is better to buy a new computer
-
i have no mean to measure the condensation, i think the working servers are hot enough to be protected against humidity

My six year old actually owns a hygrometer of her own.
