Server Room Air Conditioning (AC) Questions

Greetings. We have about a 10x10 server room with one rack.  It includes 6 switches, our firewall/appliance, our SAN, and maybe 6-8 rack servers, along with other odds and ends (couple desktops, etc.)

It's currently cooled by a Mitsubishi Mr. Slim wall-mounted AC unit.  The Mr. Slim has had numerous issues over the years (coolant leak in roof-mounted unit, replaced motor/bearings, etc.).  We're awaiting quotes on repair or replacement.

Does anyone have a recommendation for a reliable single-zone AC unit for a small server room ?  I'm looking at the newer Mitsubishis as well as TRANE.  What do you all use in your small server rooms ?

Thanks much.

Stay away from any more Mr. Slims!  We had two in the server room here before I was hired.  Both were replaced by a single 5-ton residential unit, which is what I'd recommend for you.  The option doesn't exist for me but if you have exterior wall access I'd suggest cutting a hole and installing a nice 220v window unit as a backup if you're in a hot part of the country.

We're in a cooler area.  For backups, we have a service that delivers a portable unit on short notice, so I think we're good there.  The room is also completely contained inside the building :-)   Thanks for the advice.

Good deal.. then yeah I'd def get a local hvac guy in see what he suggests.  Cooling a server room is really no different than a home outside of making sure you get hardware that's made for a very high cycle and usage time.  At our site down in MS (hot as can be) we had to get a special controller for the fan motor so the fan did not actually turn off but just slowed down when the compressor isn't running.

The commercial brands I've heard of are:  Mitsubishi, TRANE, Carrier and Gibson.  Do you recall what you went with ?  I understand that proper installation is as important as brand, but just curious.

Nah I have no clue what our brand is.. Warranty is really the biggest deciding factor IMO.  Most of the internals, just like pc's, are manufactured by the same groups of companies overseas.

But, IMHO based of the history of the Mr. Slim.. I wouldn't go with Mitsu again.

We used many Carrier, not for IT rooms, but for residential. They were very reliable, low maintenance.
