[TRNSYS-users] Type 641 (Humidifier TESS Libary) - Version 17.025

[Roberto Ruiz]

Dear TRNSYS Users,

I'm trying to implement a AHU model by coupling every component. AHU 
also comprises an adiabatic humidifier modeled by means type 641.
When I try to simulate it, I always receive a message saying that the 
entered Relative humidity is greather than 100%.

Looking in the code I found where the problem come from.
*!Check the Inputs for Problems**
** If ((RHin > 1.) .and. (mode == 2)) Call FoundBadInput(3,'Fatal','The 
return air relative humidity is greater than 100.')*

And where inputs are taken correspond to the following part of the code

!Get the Current Inputs to the Model
  Tin = getInputValue(1)
  Win = getInputValue(2)
* RHin = getInputValue(3)* !Should it be *RHin = 
getInputValue(3)/100*??? (*)
  ...

Could somebody tell me, whether this "new type" (it seems to have been 
written in other language) uses relative humidity values between 0-1 (as 
inputs)?
Or maybe there is a mistake in the code (*)?
Does this model provide output values (RH) in percentage or between 0-1?

Thanks in advance!

Roberto Ruiz
