Too cold? Are you serious? Man, I just can't win. Our readouts were reporting 68-71F... Somebody tell me what this needs to be set to for our exchange facilities. They're all pretty insanely big, so this is something to do ONCE. Nows the time, we're deep into engineering HVAC for the first fifteen. Oh, and I'd love to hear humidity suggestions as well.
Well, lets see... 1) Largest minimum operating RH for a communications device that I happen to have the specs for is 20%. 2) Smallest maximum operating RH for a communications device that I happen to have the specs for is 80%. 3) Static electricity is minimized when RH is at or above 35%. 4) RH below 25% can cause embrittlement of hygroscopic materials such as paper. 5) RH above 65% can cause mold growth and metal corrosion. 6) Humans are most comfortable when the RH is between 20% and 60%. 7) RH above 50% in cold weather can cause condensation inside of outer walls. So... perhaps a target humidity somewhere between 35% and 45% would be ideal. -Richard
