modelWatersideEconomizer
Validation of the base subsystem model with waterside economizer
Extends from Modelica.Icons.Example.
Information
This model validates
Buildings.DHC.ETS.Combined.Subsystems.WatersideEconomizer
in a configuration where the primary flow rate is modulated by means of a
two-way valve (see hexVal), and in a configuration where the
primary flow rate is modulated by means of a variable speed pump
(see hexPum).
