Re: [EnergyPlus_Support] Re: CentralHeatPumpSystem with one chiller/heater [2 Attachments]
Hello, Jim
The source/condenser temperature is constant because the PlantComponent:TemperatureSource object is used.
The calculated output is constant. I have recalculate the output in excel, considering the parameters used for the curve, and the polynomial formula is calculated by EnergyPlus properly.
The strange issue is that the leaving chilled water temperature used in the calculation is not taken from the dynamic simulation but it is the â??Reference Cooling Mode Leaving Chilled Water Temperatureâ??.
I have plotted the â??Cooling Mode Electric Input to Cooling Output Ratio Function of Temperatureâ?? (CHILLERHEATERCLGEIRFT) too and Iâ??m attaching it now. As for that curve, the temperature 6°C, which is the setpoint manager temperature, is considered as leaving chilled water temperature!?
As you can see in the second picture, the chiller-heater is working in cooling mode only one hour. Therefore the setpoint manager temperature is not met.
Best Regards
