VRF/VRV Modeling

Hi everybody!

We have few experience using eQuest and now we're trying to simulate a VRF
system.

As we all know VRF can't be modelled directly through eQuest. We have just
found a document, produced by Energysoft (Energypro), on how modeling VRF
systems in DOE-2, detailing the Fortran language behind the process.

So I copy/paste the language in "Usrlib.dat" and it apparently worked out,
but I could not simulate yet because components and efficiency curves are
not set properly though.

Does anybody knows if it might work??? Or I'm completely wrong?

The document is available at
http://www.energysoft.com/ep/VRF%20Application.pdf

Best regards

How do you insert the code in Equest?

I just copy/paste the code in the User Library ("Usrlib.dat") at
../eQUEST 3-64 Data\DOE-2 with a text editor

This looks like a really detailed document on how EnergyPro calculates VRF
energy use. It seems like something that could be applied to eQUEST using
hourly output reports and post-processing calculations.

Can anyone confirm if this is the latest document? I did some preliminary
calculations and they don't seem to quite line up with EnergyPro.

Thanks,
Robby
