Equipment

The laboratory deals with the basics of energy conversion systems. The scope of focus lies in the refrigeration engineering and in cogeneration heat engines with smaller performances in the building services sector. The Institute collaborates with small sized industries and research institutions within its framework of developmental work.

Work areas of these labs:
- Measuring and Control Engineering (closed – loop)
- Electrical and Control Engineering (open – loop)
- Electrical power supply

Research

Assigned Dissertations and Theses were and are preferred in the areas of environmentally friendly energy conversion, for example:
- Construction and installation of a Stirling engine with operating measurements
- The study of energy-saving power control concepts for refrigeration systems
- Refrigeration systems using environmentally friendly refrigerants
- The establishment of experimental stands (absorption cooling system) and extension of the trial offer
- Optimization of refrigeration systems with the help of the evolution strategy
- Calculated simulation of the operating performance of refrigerating machines using environmentally friendly refrigerants; including a program within the framework of the work group “refrigeration engineering” at universities of applied sciences, that was developed and published in this institute.

Current topics for Dissertations and Theses

• Study of cogeneration plants.
• Measures to improve the operational performance of a small performance Stirling engine
• Simulation, analysis and optimization of the operating performance of refrigerating machines
• Study of heat recovery measures with the help of the Pinch-Point procedure (heat integration)
• Development and determination of the operational performance of a cold air cooling machine
