<DIV></DIV>Sotiris,<BR> It may be that the problem lies inside the code in
an internal iteration (in other words not in a place that you can get to without
running the simulation through a Fortran compiler. I would start by
disconnecting the inputs to the fan coil (set them equal to constant values if
you can) and then watch the outputs of whatever component is just upstream to
make sure that the air state and water state going in to the fan coil is
realistic.<BR>Kind regards,<BR> David<BR><BR><BR>SOTIRIS KONSTANTELOS

vAlign=top>Dear TRNSYS users,<BR><BR>I'm trying to simulate a solar
powered air conditioning system , which uses an adsorption chiller in
order to produce chilled water for the fan coils.The problem is that
there is no adsorption chiller-component in the simulation studio. So
does anyone know how is it possible, if it's possible, to simulate the
adsorption chiller using instead the absorption chiller component?Is
there any other way?<BR><BR>I have one more question.When i'm trying to
run the simulation using of course the absorption chiller, error manager
stops simulation and warns me about an error located at the fan coil
component.The exact message is <<Attempted to take the log of a
negative number.-Enthalpy (H) is less than or equal to zero>>.The
problem is that i can't find anywhere an enthalpy parameter, except for
the psychrometrics component where there is an enthalpy output.Where
should i search? I should mention that the connected components maybe
related with this problem are these; weather
data-->psychrometrics-->building<--fan coil<--chiller
etc.<BR><BR>My regards,<BR>Sotiris<BR></TD></TR></TBODY></TABLE><BR>
