I used to work with water-cooled test equipment.
One thing that surprised me was that the water was warm. The reason I was given was that had chilled water been used, you would have all sorts of issues with condensation. So instead of cooling the system with cold water, you cooled by pumping in lots of room-temperature water. The next effect: the same amount of heat is pulled out.
- joezydeco 12y agoHow does the volume of water needed differ from the ambient temp vs the chilled temp?
- bengali3 12y agoper the chart here [1], it appears that a given volume of 40 degree(F) water is 0.03% smaller than that of 80 degree water. [1] http://www.engineeringtoolbox.com/water-specific-volume-weight-d_661.html http://www.engineeringtoolbox.com/water-specific-volume-weig...
- joezydeco 12y agoMy question was more about how much more water is needed to absorb the same amount of energy from the server. If the water pumping into the server is 20-30 degrees (C) hotter than chilled water, it can't absorb as much heat energy from the server before turning to steam. So you need to transport more water through the same system to keep the cooling effect the same.
