The development branch is issue1723_heatPumpDOE

Todo:

• Run

simulateModel("Buildings.Fluid.HeatPumps.Examples.DOE2Reversible_CoolingHeating(heaPum(scaling_factor=0.1))", stopTime=7200, method="Cvode", tolerance=1e-06, resultFile="DOE2Reversible_CoolingHeating");
plot({"heaPum.thePer.QFalLoa_flow"}, colors={{28,108,200}});

The variable QFalLoa_flow is non-zero, even when the heat pump runs at full load. The difference is due to the factor 1.2 from the part load ratio. Check what the reason is for this. See also ChillerElectricERI.cc for the EnergyPlus implementation.

• Handle loaRat and powRat. Maybe they should be dealt with in the data record because these are data and not inherent to the physics.
• Add documentation for data record, in particular also what conditions the COP is for.
• Add a validation vs EnergyPlus, in particular also valid the false loading of the compressor which is an EnergyPlus output variable.
• Add a validation for scaling_factor different from 1 (this was double counted in https://github.com/lbl-srg/modelica-buildings/pull/1724/files#diff-a933da081cf4b6de302bf0f986f77115R146 but I believe is now correct).
