[TRNSYS-users] Trnsys type 51b error

[Usama Sohail]

Hi,

I'm trying to understand how to model a direct evaporative cooling tower using type 51b but keep getting the following warning:

"The referenced UNIT has called the PSYCHROMETRICS routine withan enthalpy less than possible for the given humidity ratio. The air was assumed to be saturated at the given humidity ratio and the enthalpy was set for this condition."

The file I'm using is the cooling tower51 example file found in the Trnsys17 folder (also attached below). The only thing I changed was the simulation start and end time - I changed it to run for 8760 hours as opposed to the couple hundred hours the simulation was set for. I was hoping someone could explain to me how to resolve this issue.

Thank you!
