modelPartialHeater
BaseClass for 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.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | use_T_set | false | if true, a set temperature is used to calculate the necessary heat flow rate |
| Modelica.Units.SI.HeatFlowRate | Q_flow_nominal | 45E3 | maximum heat output of heater at design point. Only used, if use_T_set = true |

- 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 is now directly set to set temperature.
