modelEquationFitReversible_ScalingFactor
Test model for scaling up the reversible heat pump
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Model that demonstrates the use of the Buildings.Fluid.HeatPumps.EquationFitReversible heat pump model. This validation case also tests scaling the heat pump model.
The capacity, pressure drop and coefficient of performance of the scaled heat pump model are compared to the values of the non-scaled model.
