Organic Rankine Cycle

In today's world, the need to save energy and reduce greenhouse gas emissions is becoming more and more important. For this reason, technologies that can be used for waste heat utilisation are increasingly becoming the focus of current investigations. One technology that enables waste heat utilisation is the Organic Rankine Cycle (ORC). The ORC differs from the usual Clausius Rankine process in the fluid used, which in the ORC is an organic one. This offers the advantage that, due to lower evaporation temperatures at technically relevant system pressures, heat flows of lower temperature levels can be used. For the optimisation of organic Rankine processes, experimental as well as simulative methods are applied at the institute. A test stand with the working fluid ethanol is available for validation and further investigation possibilities.
