Apparently our HVAC guy's around here aren't that smart. We've talked
to 3 or 4, and they look at us with blank stares when we tell them what
we're trying to do.
Here's a standard line when talking to HVAC Guys
Them: It's winter you won't run AC
Us: Yes, but we're generating heat
Them: But it's cold outside, you don't run AC in the winter
Us: Yes, but our indoor room generates heat, and it needs to be cooled
Them: But it's winter and cold outside, you don't need AC in the winter
Us: Our room Generates heat year round
Them: Right, you run heat in the winter
Us: ....

Hi,
Your local HVAC company should be able to handle all of that for you.
We had three separate A/C units in our control room, and they ran
24x7... even when it hit -30F during the winter. Have some places come
give you quotes for what you need. :)

I'm looking to add backup cooling to a small computer room,
<200sqft. Primary cooling is via a RTU (roof top unit), but I can't
put that on our generator (240v genset vs 480v RTU). I'm thinking
like a 2 or 3 ton Split system would be perfect. Problem is we're in
the midwest, and outdoor temperatures can drop to 0 or below over the
winter. Looking at the split systems, nobody seems to know if they
will work for cooling with outdoor temperatures that low. Online
searching has yielded results for Heat Pump units, where they want to
Heat with low temperatures. Has anyone had experience with Split
systems cooling with low outdoor temperatures? Are there special
compressors built for that use? I have heard about putting a
thermostat on the fan line to cut out the compressor fan below
ambient X temp, or shrouding the compressor to keep wind from blowing
through it. But have not been able to confirm from any HVAC
contractor the validity.
This would only be for backup use, RTU Failure, or power outage. The
RTU is handling the load normally without an issue. My Current
Backup is Movincool units, but I want to reclaim the floor space, and
make it more permanent.
