Modeling water-to-air heat pump with desuperheater for DHW

asked 2016-09-11 16:03:44 -0600

Only simple air-cooled DX objects are allowed to be input into theheating source object type field for the Coil:WaterHeating:Desuperheater object in EnergyPlus.

I need to model a water-to-air heat pump with a Desuperheater for DHW heating. Has anyone found a workaround for this in EnergyPlus?

I'm surprised the Coil:WaterHeating:Desuperheater object doesn't support more coil types like the HeatPump:WaterToWater:ParameterEstimation:Cooling or the Coil:Cooling:WaterToAirHeatPump:ParameterEstimation coil types.

If you also think this would be a nice feature, vote here:

Hi, I am currently working on adding new choices for water heating desuperheater object. Look at this pull request for more details. Hopefully the next E+ release would at least cover the capability of modeling desuperheater with source type "Coil:Cooling:WaterToAirHeatPump:EquationFit"(so GSHP is available to combine) and "Coil:Cooling:DX:MultiSpeed". Besides, the tank type "WaterHeater:Stratified" would be also allowed.
