Of all the various performance curve inputs for the EnergyPlus AirConditioner:VariableRefrigerantFlow object, which can one expect to have the most impact on overall energy use?
I am trying to develop a generic set of VRF object inputs that will be representative of current VRF equipment and I'd like to prioritize any curve development effort based on impact (i.e., if i only have time to develop a few novel curves based on published equipment performance data, which should i start with?).
As a reminder here are the different curve inputs (ignoring heating vs cooling):
- Capacity Ratio Boundary Curve Name
- Capacity Ratio Modifier Function of High Temperature Curve Name
- Capacity Ratio Modifier Function of Low Temperature Curve Name
- Combination Ratio Correction Factor Curve Name
- Defrost Energy Input Ratio Modifier Function of Temperature Curve Name
- Energy Input Ratio Boundary Curve Name
- Energy Input Ratio Modifier Function of High Part-Load Ratio Curve Name
- Energy Input Ratio Modifier Function of High Temperature Curve Name
- Energy Input Ratio Modifier Function of Low Part-Load Ratio Curve Name
- Energy Input Ratio Modifier Function of Low Temperature Curve Name
- Heat Recovery Capacity Modifier Curve Name
- Heat Recovery Energy Modifier Curve Name
- Part-Load Fraction Correlation Curve Name
- Piping Correction Factor for Length in Mode Curve Name
For bonus points, what of the non-performance curve inputs would one prioritize?
Thanks in advance.
