Information
Deprecation Warning
This model is deprecated, switch to the ModularReversible approach. Read https://github.com/RWTH-EBC/AixLib/wiki/Switch-from-model-HeatPump-to-ModularReversible for further information.
This model uses the heat pump model AixLib.Obsolete.Year2024.Fluid.HeatPumps.HeatPump to simulate a whole system, including controls, pumps and second heat generator.
A set of parameters is used to estimate the model parameters.
See AixLib.Obsolete.Year2024.Systems.HeatPumpSystems.BaseClasses.PartialHeatPumpSystem for information about the features of the heat pump system.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|

| Integer | nthOrder | 3 | Order of refrigerant cycle interia |
| Evaporator/ Condenser › Condenser | |||
| Modelica.Units.SI.Volume | VCon | Volume in condenser. Typical values range from 1 to 20 l, depending on the size of the heat pump and the mass flow rate. | |
| Modelica.Units.SI.PressureDifference | dpCon_nominal | Pressure drop at nominal mass flow rate. Only relevant if a mover is used. Try to select values to match the nominal mass flow rate. | |

Represents a sum of thermal resistances such as conductance, insulation and natural convection. If you want to simulate a condenser with additional dry mass but without external heat losses, set the value to zero |
| Modelica.Units.SI.ThermalConductance | GConIns | QCon_nominal/dTPinchCon | Constant parameter for heat transfer to heat exchangers capacity. Represents a sum of thermal resistances such as forced convection and conduction inside of the capacity |
| Evaporator/ Condenser › Evaporator | |||
| Modelica.Units.SI.Volume | VEva | Volume in evaporator. Typical values range from 1 to 20 l, depending on the size of the heat pump and the mass flow rate. | |
| Modelica.Units.SI.PressureDifference | dpEva_nominal | Pressure drop at nominal mass flow rate. Only relevant if a mover is used. Try to select values to match the nominal mass flow rate. | |
| Real | deltaM_eva | 0.1 | Fraction of nominal mass flow rate where transition to turbulent occurs |
| Boolean | use_evaCap | true | If heat losses at capacitor side are considered or not |
| Modelica.Units.SI.HeatCapacity | CEva | Heat capacity of Evaporator (= cp*m). If you want to neglace the dry mass of the evaporator, you can set this value to zero | |
| Modelica.Units.SI.ThermalConductance | GEvaOut | percHeatLoss*QEva_nominal/(TEva_nominal - TAmbEva_nominal) | Constant parameter for heat transfer to the ambient. Represents a sum of thermal resistances such as conductance, insulation and natural convection. If you want to simulate a evaporator with additional dry mass but without external heat losses, set the value to zero |
| Modelica.Units.SI.ThermalConductance | GEvaIns | QEva_nominal/dTPinchEva | Constant parameter for heat transfer to heat exchangers capacity. Represents a sum of thermal resistances such as forced convection and conduction inside of the capacity |
| Initialization › System inertia | |||
