Farhan, 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. kind regards, David
