modelScrollWaterToWater_ScalingFactor
Test model for scroll water to water heat pump
Extends from Modelica.Icons.Example.
Information
Model that demonstrates the use of the IBPSA.Fluid.HeatPumps.ScrollWaterToWater heat pump model. This validation case also tests the stage input to the heat pump models.
With constant inlet source and load water temperatures, the heat pumps cycle on and off. The capacity of the scaled heat pump model is compared to the capacity of the non-scaled heat pump model.
