[TRNSYS-users] Problem with Dry Fluid Cooler (type 511)

[maxence.bureau at cofely-gdfsuez.com]

Hello,

I would like to use a type 511 (HVAC Library (TESS) - Dry Fluid Cooler), but it doesn't work.

When the value of input 2 (fluid flow rate) is higher than 0, the simulation doesn't work and an error message appear ("TRNSYS errors : one error was found in the deck...").

I have this error message in "list file" :
"*** Fatal Error at time   :         0.125000
    Generated by Unit     :    10
    Generated by Type     :   511
    Message               : The dry cooler model was unable to correctly calculate the number of transfer units (NTU) for the design condition.  Please check the design conditions carefully."

I tested the type with the defaults design conditions, but it was the same error message. I think there is a problem with input 2.

Please find attached my ".tpf" file.
Thank you for your help.

Sincerely,

Maxence BUREAU
