Information
Deprecation Warning
This model is deprecated, switch to the ModularReversible approach. Read https://github.com/RWTH-EBC/AixLib/wiki/Switch-from-model-HeatPump-to-ModularReversible for further information.
Overview
Simple test set-up for the reversible chiller model. The chiller is turned on and off while the source temperature increases linearly. Outputs are the electric power consumption of the chiller and the supply temperature.
Besides using the default simple table data, the user should also test tabulated data from AixLib.Obsolete.Year2024.DataBase.Chiller or polynomial functions.
