modelMultiplePumpsSpeed
Validation of multiple pumps model with speed-controlled pump model
Extends from BaseClasses.PartialMultiplePumps (Base class for validating the multiple pumps model).
Information
This model validates Buildings.DHC.Plants.Combined.Subsystems.MultiplePumpsSpeed by comparing an instance of that model with two instances of Buildings.Fluid.Movers.SpeedControlled_y connected in parallel. The two pumps are commanded On one after the other as they receive an increasing speed signal and work against a two-way modulating valve that gets progressively opened.
