Information

Partial model that can be extended to construct parallel chillers such as Buildings.Applications.BaseClasses.Equipment.ElectricChillerParallel and water-side economizers Buildings.Applications.DataCenters.ChillerCooled.Equipment.WatersideEconomizer.

The associated valve group val1 and val2 on medium 1 and medium 2 side are for on/off use only. The number of valves in each group is specified by the parameter n. The valve parameters can be specified differently.

The signal filter is used to smoothe the on/off signal for the valves.
