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.
