modelHeatExchanger
Validation of the base subsystem model with district heat exchanger
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model validates
Buildings.DHC.ETS.Combined.Subsystems.HeatExchanger
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).
