<p>Farhan,</p>
<p> If you have not already done so, I would recommend that you
look at the documentation for that component (in ..\TrnsysXX\Tess
Models\Documentation\06-HVACLibraryMathematicalReference.pdf). It
will give you a bit better idea what those effectivenesses refer
to. Some of the references in the documentation may give you some
hints as to how to estimate them. If they don't then I would
suggest that you change the default values by a certain percentage
and see if the results of your analysis change significantly or
not. In essence, check the overall model's sensitivity to those
values. If the model is insensitive to the values then don't worry
too much about getting precise values for them.</p>
<p>kind regards,</p>
<p> David</p>
