This would be a problem in a real system as well, not just in
simulation. You need to isolate the load flow from the source flow
by using either a primary/secondary pumping scheme or by putting a
buffer tank between the load loop and the source loop.<br>
kind regards,<br>

<p>Hi angel,</p>
<p>Yes I know how it works and the negative values mainly appear
when the flow rate to the evaporator is low. However in the
system I am simulating, I can't control this flow rate, it is
imposed by other components (cooling load from building). So
do you have other suggestions?</p>
<p>Thanks for the fast reply.</p>
<p>Regards.</p>

Hi,</p>
<p dir="ltr">I giess that the flowrate you are giving as an
input is too low related to the power requirement at the
evaporator.<br>
I suggest you to read the descripción of the type to
understand how it is working, regards</p>

<p>Hello there,</p>
<p>I am using an exhaust fired absorption chiller in
a certain system. After simulation the temperature
of the hot fluid exiting the chiller is observed
to be negative in many instances. This is
impossible in reality. I am wondering if anyone
faced a similar problem!?</p>
<p>My question is: </p>
<p>Is there a way by which I can limit the output of
a component to a certain point?? (e.g. outlet
temperature of chiller to ambient temperature)</p>
<p>Thanks in advance TRNSYS community,</p>
<p>Best regards.</p>
