<p>Ahmad,</p>
<p> I would suggest that you implement a Type65 to watch all of the
inlet and outlet conditions (temperature, humidity, and flow rate)
for the desiccant wheel pause the simulation right before the
error occurs. There is an option in the TRNExe file menu (when the
simulation is running) that allows you to specify a simulation
time at which you want to simulation to pause.Looking at the inlet
and outlet conditions might give you an idea why the device cannot
come up with a regeneration temperature that results in the
desired process stream outlet humidity ratio.</p>
<p> Also I do not know whether you are considering pressure in your
simulation but it is a good idea to do so. When air gets near its
saturation point the atmospheric pressure can mean the difference
between a condensing situation and a state in which condensation
does not occur.</p>
<p>kind regards,</p>
<p> David</p>

<p>Dear All</p>
<p>Using type 683 ( desiccant wheel) I get this error at the
middle of my simulation :</p>
<p>Regeneration temperature did not converge</p>
<p>what should I do ?</p>
