[EnergyPlus_Support] Re: CentralHeatPumpSystem with one chiller/heater [1 Attachment]

["fpasserini.tn@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

I'm reviewing how the curve output values are calculated and I've plotted some graphs in excel.

Consider the attached graph.

A curve is the â??Performance Curve Input Variable 1 Valueâ?? for the â??Cooling Mode Cooling Capacity Function of Temperature Curveâ?? (CHILLERHEATERCLGCAPFT).

The other curve is the leaving chilled water temperature Tcw,l, i.e. System Node Temperature  RAFFREDDAMENTO POMPA DI CALORE CHW OUTLET NODE [C], 

I would expect that the two values are the same, but it seems that in the calculation of the curve output the â??Reference Cooling Mode Leaving Chilled Water Temperatureâ?? (contant and equal to 6.67°C) is considered instead of the leaving CW temperature from the dynamic simulation.

I don't think it's correct, is it?

Regards
