Overview
open the class to add methods to return sizing values
Instance Method Summary collapse
-
#applySizingValues ⇒ Object
Takes the values calculated by the EnergyPlus sizing routines and puts them into this object model in place of the autosized fields.
-
#autosize ⇒ Object
Sets all auto-sizeable fields to autosize.
-
#autosizedRatedFlowRate ⇒ OptionalDouble
Takes the total rated flow rate and returns per-pump values as an optional double.
-
#autosizedRatedPowerConsumption ⇒ Object
returns the autosized rated power consumption as an optional double.
-
#autosizedTotalRatedFlowRate ⇒ Object
returns the autosized rated flow rate as an optional double.
-
#ratedFlowRate ⇒ OptionalDouble
Takes the total rated flow rate and returns per-pump values as an optional double.

Instance Method Details
#applySizingValues ⇒ Object
Takes the values calculated by the EnergyPlus sizing routines and puts them into this object model in place of the autosized fields. Must have previously completed a run with sql output for this to work.
