[Equest-users] VRF System EER

[Joel Jude Tadeo via Equest-users]

Hello everyone,



We have been modeling VRF units through PVVT by eQUEST for some time now.
One of the most asked question is how we would be incorporating the System
EER in lieu of the Equipment EER. Most of our designers size their outdoor
units larger by at least 10% than the connected load to assure the system
to operate at a much higher EER (part load). With this in mind, from what
report can we see the System EER during part load operation?



Please correct me if I’m wrong, but the usual modeling process is to input
the Full load EER in the EIR section of the detailed design interface, and
let the curves take care of the part loading. We have of course used some
of the manufacturers part load curves as reference which showed a greater
savings in cooling energy than the default eQUEST curves. Is there a report
perhaps that we can use to see the part load EER in a particular time?



Thank you for your time.



Regards,



Jude
