Is there any reference which describes the details of the fan curves in eQuest library? The mechanical equipment section is empty in DOE2.2 library file, and I didn't find any other resource about the fan curve description. Just wondering what's the difference among the following curves and any things that we should care about when choosing those curves?
Which DOE-2.2 library file are you referring to? The curves you're showing on the screenshots are in the eq_lib.dat file. This file is not typically empty. Figure 37 in the DOE-2 help (look for the help onSUPPLY-KW/FLOW) shows you part-load operation for different methods of air flow control, if this doesn't help, I would suggest plotting the curves to see if their part-load operation describes what you intend to model.
I am actually looking for the introduction of the curves so was checking the document "DOE22Vol4-Libraries". Was wondering what system or fan that each curve is suitable to and if there is any reference. If no such file, guess I can only plot and see its operation. Since other items have detailed description in the help file but the fan curves in the captures I cannot find the reference
