[Bldg-sim] eQUEST GSHP Unmet Load Hours

[Robby Oylear]

Hi everyone,



I’m trying to model a ground source heat pump system in eQUEST using a
Water Loop Heat Pump system attached to a ground source heat exchanger.
The system seems to work fine during occupied hour but it just can’t meet
morning warm-up loads.  I’m doing a systems energy analysis for our local
energy code compliance and there is a mandatory night setback of 55 °F
from 70 °F in heating.  During winter months the system doesn’t seem to be
able to jump from 55 °F to 70 °F space temperature in less than 1-2 hours.
I’ve double checked the fan schedules and the system is allowed to come on
during this time.



Does anyone have any suggestions for getting the system to meet these
unmet load hours?
