They freeze up when you set the temp too low most of the time. The unit tries to do what you tell it too, but the cooler it tries to make the room, the more condensation will build up around the coil, which freezes because it’s pushing or beyond the cooling spec of the unit. Eventually the coil is blocked with ice so that no air can pass through, which means you just lost your AC capabilities. As the ice thaws you get the water. But again, I have never seen water come out the actual duct. I mean it’s possible if the coil and ice are above the ductwork somewhere when it begins to warm up in that area leaking water into the airflow. But outside of that it makes little sense to me. AC units generally dehumidify the air, not the opposite. That’s why they need the drip trays.

I have seen it happen to the exact type of systems you are describing. Heck, I have even had in happen in my car AC. All units are prone to a little freeze up once in a while. Not sure the specifics of why, etc to be honest... -Sam From: Mike Gill [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 29, 2008 4:58 PM To: NT System Admin Issues Subject: RE: Its 89 degrees in our server room!!! I have never seen any AC unit cheap or otherwise spit condensation out the cooling vent. All the internal units I’ve looked at have internal drip pans that can be plumbed too if necessary. The $400 portables I’ve used personally from Home Depot do this. Condensation comes from outside the evaporator coil. This isn’t in the path of air moving internally through the unit’s ductwork. Have you guys actually witnessed this sort of thing or what? -- Mike Gill From: Sam Cayze [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 29, 2008 2:27 PM To: NT System Admin Issues Subject: RE: Its 89 degrees in our server room!!! Those MovinCool’s are designed for electronic equipment, and probably (hopefully), have safe-guards built-in to prevent this.
