Hi,

The Water-Water Parameter-Coefficient Generator(Cooling&Heating).pdf which comes with the spreadsheet has the following description

RatedLoadVolFlowRate: Rated load side volumetric flow rate (m3/s) which
corresponds to the highest load side heat transfer rate listed in the catalog data.
RatedSourceVolFlowRate: Rated source side volumetric flow rate (m3/s) which
corresponds to the highest load side heat transfer rate listed in the catalog data.
RatedQload: Rated load side heat transfer rate (W) which is the highest load
side heat transfer rate listed in the catalog data.
RatedPower: Rated power consumption (W) which corresponds to the highest
load side heat transfer rate listed in the catalog data.

Hi All,

for the objects "HeatPump:WatertoWater:EquationFit:Heating" and "HeatPump:WatertoWater:EquationFit:Cooling" , the following inputs are needed:

"Rated Load Side Flow Rate"

"Rated Source Side Flow Rate"

"Rated Capacity"

"Rated Power Consumption"

Does anyone know what "rated" refers to in this case? I assume it means a testing condition - but which one?

Thanks,

Karen
