Record for heat pump plant
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.
Extends from Modelica.Icons.Record (Icon for records).
