RE: Temperature -- MIDRANGE-L

All the ones I've seen have a an exhaust duct of some sort that you use to route the waste heat out of
the room.

I never understood how those portable units could help.....
A/C works by capturing heat from the air in the location
being cooled, then transporting that heat to another location
where that energy can be released. If the front side of the
unit blows cold air, then the back side must be blowing hot
air. Once the unit is in a room, it seems like the net
effect will just be to increase the overall ambient
temperature of the room (the unit itself adds heat as it
operates).... I guess you could leave it in the doorway, but
that might cause its own problems....

Good thing I'm in IT and not in HVAC..... ;-)

What's the temp? That machine will run just fine even after
you start to sweat profusely. You can get a nice portable A/C
unit on rollers for less than $2K.

I have expressed concern that I think the temperature in our
computer room is excessive & may detract from life expectancy
of our computer, which in turn will advance the date at which
we have to pay exorbitant cost of moving our BPCS license to
another box.

All I was asking for was an exhaust fan to suck the hot air,
out of the computer room, where often the door is left shut
because people not want to hear noise of printer. I think
printer noise is barely noticeable.

I have been asked what is the maximum prudent temperature is
Ok to run our AS/400 model 170, and what is its optimal
temperature range. I used to know. I forgot where to look that up.

I think there's also a humidity factor, but I have not
noticed that being opperessive.
