as well. Appendix G specifies that Direct Expansion be used as the
cooling type for System 6. However, the PIU system in eQuest does not
allow you to use DX coils. I have seen several archived posts on this
same question that say to model a chiller equivalent to the DX coils, but
nothing further. I have redefined the chiller performance curves
accordingly with no success. Has anyone set up this system succesfully in
eQuest? </span></font><o:p></o:p>
