Fresh out of its box, this APC InRow water chiller demonstrates an alternative approach to the typical raised-floor hot/cold aisle air cooling scenario. Several of these are placed along rows of racks, spaced at intervals to allow maximum cooling efficiency. The server room will still operate in a hot/cold aisle format, with the maximum cold aisle temperature at 81 degrees Fahrenheit with the water temperature at 65 degrees.
This close-coupled, in-row cooling is an efficient water cooling method. The MGHPCC uses these distribution units to bring chilled water from the cooling tanks to the servers.
