modelEquationFitReversible
Test model for reverse heat pump based on performance curves
Information
Example that simulates the performance of Buildings.Fluid.HeatPumps.EquationFitReversible based on the equation fit method. The heat pump takes as an input the set point for the heating or the chilled leaving water temperature and an integer input to specify the heat pump operational mode.
