The E+ model for 'airconditioner:variablerefrigerantflow' does not have defaults for the following curves:

, !- Heat Recovery Cooling Capacity Modifier Curve Name , !- Heat Recovery Cooling Energy Modifier Curve Name , !- Heat Recovery Heating Capacity Modifier Curve Name , !- Heat Recovery Heating Energy Modifier Curve Name

Can someone recommend sources/references for these?

Thank you for your answer. This is very helpful.

Example EMS code for PlantComponent:UserDefined Hello, Is there example Erl code somewhere for an EMS PlantComponent:Use

The current minimum outdoor temperature for compressor operation for EnergyPlus objects 'Coil:Heating:DX:VariableSpeed' and 'AirConditioner:VariableRefrigerantFlow' is -20 DegC. The current cold-climate heat pump technology can operate easily down to -25 DegC. Ideally if this temperature can be allowed to drop to -30 DegC.

What is the best way to request this kind of change in EnergyPlus? This is really not a feature request. It's more of minor code change. Is there a web link someone can share for entering this request for change in e+?

Why not use a cooling tower to do the cooling in this case? EnergyPlus allows plant loops of type "cooling","heating", o

Every output variable has a frequency input field. Have you tried using that?

It's possible that this feature is not supported by the OS interface but supported by the SDK through measures.

After doing further testing with e+ 8.9, it turns out that the dx heating coil (Coil:Heating:DX:SingleSpeed) can actuall

Thanks, this is exactly what I was looking for.
