Information

Model of a reversible heat pump.

This model extends BuildingSystems.Fluid.HeatPumps.ModularReversible.Modular and selects the constant Carnot effectiveness module for heat pumps ( BuildingSystems.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.ConstantCarnotEffectiveness) and chillers ( BuildingSystems.Fluid.Chillers.ModularReversible.RefrigerantCycle.ConstantCarnotEffectiveness) to model a reversible heat pump. For the heating operation, the approach temperatures are fixed at nominal values to avoid nonlinear system of equations.

Furthermore, losses are enabled to model the heat pump with a more realistic behaviour:

• Heat losses to the ambient (can be disabled)
• Refrigerant inertia using a first order delay
• Evaporator frosting assuming an air-sink chiller

For more information on the approach, see BuildingSystems.Fluid.HeatPumps.ModularReversible.UsersGuide.
