[EnergyPlus_Support] Calculating Water-to-Air Heat Pump Curve-fitting Coefficients
I'm trying to generate curve-fitting coefficients for:
COIL:WATERTOAIRHP:EquationFit:COOLING and
COIL:WATERTOAIRHP:EquationFit:HEATING
objects. The EP InputOutputReference alludes to using a generalized
least-squares method and Tang, in Appendix B of his paper (Modeling
Packaged Heat Pumps In a Quasi-steady State Energy Simulation Program)
references an Excel spreadsheet for calculating these. But there are
no specifics on exactly how to do this.
Does anyone know how I can get a copy of this spreadsheet or how I can
generate these coefficients using the current version of EnergyPlus?
Is it possible that the coefficients published in the EP examples (for
example, HeatPumpWaterToAirEquationFit.idf) are universal enough to be
applicable to a wide variety of heat pump brands (with possibly only
adjustments to rated flowrates, capacities and power consumption
necessary)? Any thoughts would be much appreciated!
