Hello,
I am trying to simulate a data center with Heat exchangers in a closed loop so that the air from the CRAC unit (the heat exchanger/cooling coil) cools the air , then pushes it to an underfloor plenum and then to the RACK units (the servers) and then back to the CRAC- heat exchanger outlet to remove the heat from the system.
I am trying to get the CRAC units to be like in real life where you have the cooling coil (the CRAC) and then a centrifugal fan that pushes the air.
The problem is that It seems i can't use the both in a row.
the heat exchanger have flow rate for its own and if i put a centrifugal fan afterward I have a problem with the pressure in the system, So autodesk CFD doesn't know where to push the air from and where should it flow.
I would get 2 static pressure 0 in the same system (the heat exchanger have 0 pressure in its outlets, and the centrifugal fan also have one).
Would appreciate your help.
Thanks.
