Dear Lee,
Thank you for your answer. The errors disappear when I divide the air
flow or the water flow by 10.
But I have checked and my flow rates are well set and given by the
evaporative cooler designer.
Moreover, it is weird that the errors disappear wether I divide the
air flow by 10 or the water flow by 10...
Do you have any idea?
Best regards.

Hello, SAULNIER.
I think you should check whether the water and/or air flow rates are
set appropriately. Try changing the flow rate of either stream to see
if the warnings still appear.

Dear Trnsys users,
I would like to model an evaporative cooling tower type51b. When the
inputs for dry bulb temperature and wet bulb temperature are given by
Type15, a lot of warnings occur whith the following message :
"The referenced UNIT (type51b) 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."
I have tried with different meteonorm files but I can't manage to
avoid these warnings.
Do you have any idea of the source of this problem ?
Thanks,
Best regards.
