modelPartialCooler
BaseClass for cooling heat exchangers in air handling units
Extends from Components.BaseClasses.PartialComponent.
Information
This partial model provides a idealized heat exchanger. The model considers the convective heat transfer from the heat transfer surface in the air stream. Moreover the heat capacity of the heating surface and the housing of the heat exchanger is considered.

- April, 2019, by Martin Kremer:
First implementation. - August, 2019, by Martin Kremer:
Added possibility to use set temperature. - December, 2019, by Martin Kremer:
Removed internal PID. Output temperature and humidity are now directly set to set temperature.
