I am building a residential model in EnergyPlus in a heating dominant climate. The model currently has DX:SingleSpeed for cooling and Coil:Heating:Fuel for heating. I would like to change the HVAC such that it is now a ASHP (preferrably min-split ducted) with the furnace as a supplement during winter months.
I've looked up product specs to build out the performance curves using the axillary programs, but am unable to figure out the node and equipment placement with the furnace in a Blow Through position. I'm also consistently getting an error for not having a defrost curve, which I know is a known error, but cannot figure out how to build this curve to appease EnergyPlus.
Please provide some guidance to resources which may help.
tl;dr : looking for examples of HVAC diagrams with ASHP system (preferably min-split ducted) with furnace as supplement and/or resources to build defrost energy input ratio function.
