modelScrollWaterToWater_ScalingFactor

Test model for scroll water to water heat pump

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

Model that demonstrates the use of the Buildings.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.
