ZoneHVAC:HybridUnitaryHVAC

Hybrid Unitary HVAC. A black box model for multi-mode packaged forced air equipment. Independent variables include outdoor air conditions and indoor air conditions. Controlled inputs include operating mode, supply air flow rate, and outdoor air faction. Empirical lookup tables are required to map supply air temperature supply air humidity, electricity use, fuel uses, water use, fan electricity use, and external static pressure as a function of each independent variable and each controlled input. In each timestep the model will choose one or more combinations of settings for mode, supply air flow rate, outdoor air faction, and part runtime fraction so as to satisfy zone requests for sensible cooling, heating, ventilation, and/or dehumidification with the least resource consumption. Equipment in this class may consume electricity, water, and up to two additional fuel types.
