@gtfierro @jbkoh How could we model a heat pump which is a split system? These definitions work well for a packaged unit, such as the illustrated "Air_Source_Heat_Pump":

However, a split system would have both a Condensing Unit and an FCU. This, too, is a Heat Pump:

In some sense, a split system is more of a "Heat Pump System", where as a packaged unit is a "Heat Pump Equipment"

We do have "Heat_Pump_Condensing_Unit", perhaps "Heat_Pump" class could be modified to "Heat_Pump_Packaged_Unit" for clarification.

I think the distinction between a packaged and split system just the location/relationships. Similar to how an RTU is just an AHU that hasLocation roof.

Package System > feeds > Zone
Split System Condenser Unit > feeds > Evaporator_Unit (do we have this?) > feeds > Zone

@MatthewSteen In the split-system example above, this would be achieved by using the Heat_Pump_Condensing_Unit > feeds > FCU

In this case, do you agree that Heat_Pump should be "Packaged Heat Pump"?

Renamed "Heat Pump" to "Packaged_Heat_Pump" and added air/water/ground source to all condensing unit classes. In doing so, we can represent the same level of detail for both Packaged and Split System variations.
