This was all good with the exception of temp for condensation. Condensation can occur at just about any temp (within reason) that is what Dew Point is. Humidity is Dew point/(room) Temperature. When they match you have humidity of 100% and start to see condensation/fog. Anyway this is from flight school. I have heard different engineers recommend 40% humidity and maybe 67.5 degrees temp. Something about enough humidity to avoid static dischargies etc...?? PS- Anyone know of any colo space in Jacksonville, Fl?? At 4:07 AM -0000 10/7/98, Michael Dillon wrote:

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.My experience is that electronic/computer type equipment runs best when it is in a cool environment, i.e. too cold for a human in T-shirt to work in for very long. And when the ambient temperature gets above room temp, then you get too many wierd and unexplainable problems occurring or just plain equipment failure. Sean Donelan is right to worry about condensation and I believe that you should maintain a fixed humidity level in the air in your facilities. Keep the temperature below 18C but not so low as to cause condensation. Get some Compaq engineers to recommend a humidity level and ask your HVAC peopel to keep it constant. In Palo Alto this will probably mean adding humidity in the summer and removing humidity in the winter. In the Northeast you would need to do the reverse. -- Michael Dillon - E-mail: michael () memra com Check the website for my Internet World articles - http://www.memra.com
