Oh, Hai!
This is the penthouse. You are looking at the UPS room.
"Why am I getting a call from the temp sensors saying that zone 1 is 85 degrees?"
AC FAIL!
Uh-oh....it's got another 2 minutes before I go into bypass and shut the thing down to prevent issues.....
BOF (Big Ol' Fan) to the rescue!
Oh Noes!!!...it's still staying steady after around an hour, BOF isn't helping!
AC-Trifecta to the rescue! Yes...3 AC units....1 through window (now wall ~6.5kbtu), 1 through wall (~12k BTU), and one portable AC (~10kbtu). Unfortunately, 50+ years ago when this building was built - 20a to the whole penthouse was considered acceptable (I guess....). Luckily there is nothing else on the circuit....well now there's two AC's. The portable actually goes outside the wall, to a 10ga cable, down to the next floor, and has it's own 20a dedicated circuit.
85 down to 68 overnight....it stays at around 72 during the day.
The AC guys are here fixing the old unit, bad compressor. The through wall unit will stay in here as a backup. The Window/Temp will go back somewhere.
I'm going to strap the BOF to my back and get a really long extension cord. I think I can fly with that thing....
Last two shots are the new AC for the server room (one of 3) and last shot is the actual UPS - Mitsubishi.
Camera phone, sorry about crappy pix.
