modelCalculateEfficiency
Calculate the COP or EER of a device
Extends from Modelica.Blocks.Icons.Block.
Information
This model is used to calculate the COP or the EER of a device. As the electrical power can get zero, a lower boundary is used to avoid division by zero.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Units.SI.Power | PEleMin | If eletrical power consumption falls below this value, COP will be set to zero |
