modelConstantEffectiveness

Heat exchanger with constant effectiveness

Extends from Buildings.Fluid.HeatExchangers.BaseClasses.PartialEffectiveness.

Information

Model for a heat exchanger with constant effectiveness.

This model transfers heat in the amount of

Q = Qmax ε,

where ε is a constant effectiveness and Qmax is the maximum heat that can be transferred.

For a heat and moisture exchanger, use Buildings.Fluid.MassExchangers.ConstantEffectiveness instead of this model.
