Problem with cooling in ITA

[jzurera]

Hi Team,

in a project we are seeing these errors in some random racks in our modeling in the Inlet and Exhaust temperature:

 In some racks it works fine, but in another we see those rare values. 

Then, in the same room, we receive this error in the CFD calculated, but all the CRAHs are below 25% of capacity:

Hi Javier,

Appears to be configuration related - I guess manually entered temperature values breaking the cooling calculations and complaining about invalid (and unrealistic) temperatures.

You might want to check the setup and see where you have entered temperature values - that could be something like supply and measured return temperatures on cooling units. I would suggest to leave the "Measured Return Temperature" filed empty, and let the software do the cooling calculations.

If you have hot/cold aisle containment systems in the setup, then you might want to check racks/other equipment are completely placed inside the containment system. Orientation and location of the equipment/racks/Cooling units/etc may also have impact in cooling calculations.

Kind regards,

Jef
