Hi Morteza,<br>
I have not reviewed the results or detailed inputs of your model,
but one thing to be aware is that depending on the rating conditions
of your efficiency data, you may have to adjust the EIRs to be
consistent with DOE-2 performance curves. The default DOE-2 curves
are normalized to the GSHP rating condition, so if using these and
if your efficiency data is @ the WSHP rating condition, you will
need to apply these adjustments.<br>
<br>
Here is the table from the DOE-2 help provided with eQUEST. There
is a library of DOE-2 WSHP curves available from ClimateMaster that
do not need these adjustments.<br>

This is a multifamily mid-rise building, 9 floors above
grade. Per ASHRAE Table
G3.1.1A the Baseline HVAC system is system 1 (PTAC with
hot-water fossil fuel
boiler) 9.3 to 11 EER. <br>
Selected HVAC system for the proposed design is WLHP (3
Ton High efficiency HP
by Daikin, 15.9 EER and 4.83 COP) with 2 cell cooling
tower, DOAS unit (9.8 EER)
and 2 Boilers (0.92 Eff.).</span></p>
