High density load in datacenter

Dear Unmet team,

Running a simulation for a datacenter project, in a 200 M2 IT room with 160 Kw IT load, something funny thing happens:

1- If the IT load is low (10 Kw) the simulation runs well 2- If the IT loads is high (160 Kw) the simulation fails, warnings and severe are presents.

Warning ** Inside surface heat balance did not converge with Max Temp Difference"

and

severe the surface temperature is out of bounds,

some body knows how to solve it?

Thanks

High density load in datacenter

Dear Unmet team,

Running a simulation for a datacenter project, in a 200 M2 IT room with 160 Kw IT load, something funny thing happens:

Description, 200 m2 area, 3 mt heigh, DX air system air cooled, roof and walls exposed, floor ground. Supply temperature 20C, return temperature 32C.

1- If the IT load is low (10 Kw) the simulation runs well 2- If the IT loads is high (160 Kw) the simulation fails, warnings and severe errors are presents.presented.

Warning ** Inside surface heat balance did not converge with Max Temp Difference"

and

severe the "the surface temperature is out of bounds, bounds"

some body knows how to solve it?

Thanks

Dear Unmet team,

Running a simulation for a datacenter project, in a 200 M2 IT room with 160 Kw IT load, something funny happens:

Description, 200 m2 area, 3 mt heigh, 3m height, DX air system air cooled, air-cooled, roof and walls exposed, floor ground. Supply temperature 20C, return temperature 32C.

1- If the IT load is low (10 Kw) the simulation runs well well

2- If the IT loads is high (160 Kw) the simulation fails, warnings and severe errors are presented.
