Re: [TRNSYS-users] Error 114



Ioannis,
I would imagine that the error is not irrelevant - it is telling you that one of the components in your simulation has called the TRNSYS moist air properties routine with properties that are not physically possible and that under these circumstances, the TRNSYS psychrometrics routine is not able solve for the state of the air. What I don't know is why the steam splitter and steam turbine models are calling the psychrometrics routine instead of the steam properties routine. That, however, is a question that hopefully the STEC library authors can answer.
Kind regards,
David

Hello,

I use the STEC library in order to simulate the operation of a parabolic
trough solar thermal power plant. When I connect a steam turbine stage to a
controlled steam splitter in the following way:

turbine inlet pressure->outlet pressure 2 (splitter)

I get the following error message " The utility routine PSYCHROMETRICS, which
calculates the thermodynamic properties of moist air, has been called with a
wet bulb temperature above the maximum wet bulb temperature for the given
pressure. Please check the routine which calls the psychrometrics routine for
possible sources of errors-Error 114".

Does anybody have an idea about the cause of this error, because it seems
irrelevant to me?
Regards,

Ioannis Karathanassis
