recordHeatPumpPlant
Extends from Modelica.Icons.Record (Icon for records).
Information
This record provides the set of sizing and operating parameters for the heat pump plant models within Buildings.Templates.Plants.HeatPumps.
Most of the parameters should be assigned through the sub-record dedicated to the controller. All parameters that are also needed to parameterize other plant components are propagated from the controller sub-record to the corresponding equipment sub-records. Note that those parameter bindings are not final so they may be overwritten in case a component is parameterized at nominal conditions that differ from the design conditions specified in the controller sub-record.
Only identical heat pumps are currently supported.
The heat pump performance data are provided via the subrecords
hp.perHeaHp and hp.perCooHp for the heating mode
and the cooling mode, respectively. For the required format of the
performance data files, please refer to the documentation of the block
Buildings.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.BaseClasses.TableData2DLoadDep.
