modelHexElementLatentLoop
Model that tests the basic element that is used to built heat exchanger models
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This test circulates air in a loop. Air has a constant inlet temperature into the coil. The model verifies that the air will be dehumidified to the dewpoint of the coil surface.
