New performance data model for the HeatPump model

[FWuellhorst]

What is the problem?

The heat pump model builds on a black box for the vapor compression cycle. In my master thesis, I developed a python based performance map approach which enables studies on different fluids and flowsheets of heat pumps. To use this approach in future projects, I will implement the approach also for the AixLib.

How do we want to solve it? Describe the solution you'd like

• Implement a new PerformanceData model based on SDF tables which uses these tables.
• Adjust controller models affected by this new approach (e.g. OperationalEnvelope).
• Add an examplary .sdf file with different fluids and flowsheets
• Link towards the VCLib python tool for map generation.

In this issue, I will also tackle #912.

I also added a heating rod model as this is relevant for bivalent heat pump models
