modelPrescribedOutlet_dynamic

Model that demonstrates the ideal heater/cooler model for a prescribed outlet temperature, configured as dynamic

Extends from Buildings.Fluid.HeatExchangers.Validation.PrescribedOutlet (Model that demonstrates the ideal heater/cooler model for a prescribed outlet temperature, configured as steady-state).

Information

Model that demonstrates the use of an ideal heater and an ideal cooler, configured as dynamic models.

This example is identical to Buildings.Fluid.HeatExchangers.Validation.PrescribedOutlet except that the heater and cooler models are configured to have a time constant of 60 seconds at nominal flow rate. At lower flow rate, the time constant increases proportional to the mass flow rate.
