Infrastruxure Cooling Requirements

[Anonymous user]

If we were to put a 20 cabinet Infrastruxure solution in place, what would our cooling requirements be to maintain 70 degrees F ? Assuming each cabinet has 30 AMPs of 110V service.

Hi

We're in the process of a similar setup, albeit far smaller. 6-8 racks, 3KW per rack - the specs here;

States the cooling is 4.9KW - is there an accurate way of basing the cooling KW against the power KW of our setup. e.g. Our power is say (6x3=18KW) - does that mean I need 4 x SCs - or would 3 suffice?

Cheers

If you were to use the Rack Containment System with the SC's, 3 evenly spaced SC's would be plenty. The RACS jumps the cooling capacity to about 7-10 KW. If you are planning on throwing the SC's in the row without the brackets, 4 evenly spaced units would do the trick.

Thanks.

Man, this forum is AWESOME! Hiya Joey,

Ok, there's a reason clowns have red noses. It's the result of blunt force trauma from poking it in other people's bizness (slamming doors, projectiles which include staplers, blackberries, etc). Maybe if y'all can take up a collection, I can buy some bizness of my own and stay out of yours 🙂

AnYways.... I've put a bunch of In-Row SC cooling units in computer rooms, and I've considered them for others.

The SC is designed to provide cooling to a space and equipment, but not to add overall cooling capacity to a building. They are designed to transfer heat out of the space, typically up to a drop ceiling plenum, heat which must be absorbed and rejected outdoors by the building cooling system. A perfect fit if the building air runs all the time and the drop ceiling space is a plenum return to the building air system.
(I say typically, because I've designed to exhaust out a window before...VERY atypical and not a permanent fix)

Check out these application notes during consideration of the In-Row SC during your research and selection of the correct cooling solution:

Hello,

With 20 cabinets running around 3500 Watts, maximum, that would put your total datacenter center consumption around 70KW. If you are looking at InRow type cooling, we have the following options.

The InRow SC is a self-contained unit that will cool approximately 7-10KW of power use.

The InRow RC is a chilled water cooling unit, that has the same footprint as the SC, but can cool up to 30KW of power consumption.

Finally, for InRow cooling, the InRow RP is either chilled water or coolant based, and can cool up to 70KW of power consumption.

These are just InRow based solutions, to cool at a rack level. If you are looking for entire room based cooling, you can check out our options through the following link, but the best course of action may be to open a line of communication with our reps in your area. You can start this by calling our sales support team at 800-890-4272 and follow the options for sales support. They can get you in contact with our specific rep in your area, who can discuss and explain any room cooling options that may be beneficial.
