modelReciprocatingWaterToWater_Dynamic
Test model for variable speed reciprocating water to water heat pump
Extends from Modelica.Icons.Example.
Information
Model that demonstrates the use of the Buildings.Fluid.HeatPumps.ReciprocatingWaterToWater 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 apparent capacity of the dynamic model is compared to the steady-state model and to the condenser heat transfer rate.
