Partial record to specify performance data for load-dependent data-based models

Information

Overview

This is the base record class for heat pump and chiller models that use the block Buildings.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.BaseClasses.TableData2DLoadDep to calculate the capacity and power.

This class provides the path to the external data file with the performance data (parameter fileName) as well as the PLR values at which capacity and power are specified (parameter PLRSup). The external data file must be formatted as specified in the documentation of the above block. Please also refer to this documentation for the definition of the parameter PLRCyc_min.

Extends from Modelica.Icons.Record (Icon for records).

Record to specify performance data for load-dependent data-based HP models

Information

This is the base record class to specify the parameters of the model Buildings.Fluid.HeatPumps.ModularReversible.TableData2DLoadDep.

In addition to the parameters defined in Buildings.Fluid.HeatPumps.ModularReversible.Data.TableData2DLoadDep.Generic table data for upper temperature limits is included. Please refer to the documentation of Buildings.Fluid.HeatPumps.ModularReversible.Controls.Safety.BaseClasses.PartialOperationalEnvelope for guidance on how to populate this table.

Extends from Buildings.Fluid.HeatPumps.ModularReversible.Data.TableData2DLoadDep.Generic (Partial record to specify performance data for load-dependent data-based models).
