[EnergyPlus_Support] Re: Warnings
Thank you Jeannieboef for your response.
I have taken most of them are autosizing. Are you referring to the following to autoze, then this waht my configuration if Chiller:Electric:EIR looks like
Chiller:Electric:EIR,
Chiller2, !- Name
2110200, !- Reference Capacity {W}
5.0, !- Reference COP {W/W}
5, !- Reference Leaving Chilled Water Temperature {C}
32, !- Reference Entering Condenser Fluid Temperature {C}
autosize, !- Reference Chilled Water Flow Rate {m3/s}
autosize, !- Reference Condenser Water Flow Rate {m3/s}
Chiller2 CentCapFT, !- Cooling Capacity Function of Temperature Curve Name
Chiller2 CentEIRFT, !- Electric Input to Cooling Output Ratio Function of Temperature Curve Name
Chiller2 CentEIRFPLR, !- Electric Input to Cooling Output Ratio Function of Part Load Ratio Curve Name
0, !- Minimum Part Load Ratio
1, !- Maximum Part Load Ratio
1, !- Optimum Part Load Ratio
0.25, !- Minimum Unloading Ratio
Chiller2 ChW Inlet, !- Chilled Water Inlet Node Name
Chiller2 ChW Outlet, !- Chilled Water Outlet Node Name
Chiller2 Cnd Inlet, !- Condenser Inlet Node Name
Chiller2 Cnd Outlet, !- Condenser Outlet Node Name
WaterCooled, !- Condenser Type
0, !- Condenser Fan Power Ratio {W/W}
1, !- Compressor Motor Efficiency
5, !- Leaving Chilled Water Lower Temperature Limit {C}
ConstantFlow, !- Chiller Flow Mode
0, !- Design Heat Recovery Water Flow Rate {m3/s}
, !- Heat Recovery Inlet Node Name
, !- Heat Recovery Outlet Node Name
1; !- Sizing Factor
Thanks
