ZoneHVAC:HybridUnitaryHVAC Second and Third fuel types - consumption is not metered

[mjwitte]

Issue overview

Based on code review while removing fuel type synonyms, it appears that:

1. These energy consumption variables for ZoneHVAC:HybridUnitaryHVAC are not connected to a meter:
   Zone Hybrid Unitary HVAC Secondary Fuel Consumption
   Zone Hybrid Unitary HVAC Third Fuel Consumption Rate

2. Zone Hybrid Unitary HVAC Supply Fan Electric Energy is metered, that seems ok. But Zone Hybrid Unitary HVAC Electric Energy is also metered. If the fan energy is included in this, then it's gettting double-counted on the electric meter.

3. Field: First Fuel Type has a full range of choices, but the default it electricity (in code, noted in the IDD), but this appears to be connected to the Electric meter - not variable based on which fuel type is specified in the input. Actually, I'm not finding where this is metered.

4. There are several (maybe more) variables which have SetupOutputVariable statements but searching HybridUnitaryAirConditioners.cc for the variable name shows it does not appear to be used. Stopped looking after these three, there could be more?

            SetupOutputVariable("Zone Hybrid Unitary HVAC Electric Energy",
                                OutputProcessor::Unit::J,
                                ZoneHybridUnitaryAirConditioner(UnitLoop).FinalElectricalEnergy,

            SetupOutputVariable("Zone Hybrid Unitary HVAC Requested Outdoor Air Ventilation Mass Flow Rate",
                                OutputProcessor::Unit::kg_s,
                                ZoneHybridUnitaryAirConditioner(UnitLoop).MinOA_Msa,
            SetupOutputVariable("Zone Hybrid Unitary HVAC Ventilation Air Mass Flow Rate",
                                OutputProcessor::Unit::kg_s,
