Why are my primary heating components not heating to full capacity before secondary components activate?
I am modeling zones in EnergyPlus with primary heating from baseboard radiators, secondary heating from VRF heat pumps, and any remaining heating from SingleDuct:Uncontrolled objects. My ZoneHVAC:EquipmentList objects are written as follows:
My baseboard objects are as follows:
Despite being set as primary heating components, the baseboard radiators are not heating to sufficient capacity before the VRF heat pumps kick on. I have tried autosizing and hard-setting high capacities for the baseboards. The majority of the heating is still provided by the VRFs when I look at the end use breakdown.
Anyone know why my baseboards aren't being used with sufficient capacity to handle most (if not all) of the heating loads?
I have minimal unmet load hours in my zones, suggesting they are indeed being conditioned to the correct temperatures. I have tried both autosizing and hard-inputting the specs for the other plant components, to no avail:
