With the coming of fall, tempatures have started going down. This brings up a unique re-occuring problem at work. I work at a datacenter and during the cooler months the big challenge is keeping the room cool. Yep, as hard as that is to believe it's harder to keep a datacenter cool in the cold then it is when it's hot out.

The big issue we run into is compressor presures on the various A/C units. This leads into the silly design category. Now the A/C units have sensors on them to detect all sorts of problems and most of them make sense and stop the unit from burning itself up and costing lots of money to repair. I don't really have any problem with the low presure, high presure, air flow types. This get raised and the unit basically stops. The fans still run to keep air moving but the compressors shut down. 

So the other morning I come in to work, go on my morning tour through the facility. What do I find? One of the A/C units had determined that it was too hot in the room and triggered the room overtempture alarm. Come to find out this alarm also stops the compressors from running. Ok, explain that to me? Oops the room is to hot, so I'm gonna stop cooling it! 

Some days you just want to smack some of these engineers...
