Abstract:
Works in the field of the ORC`s with mechanical power of 1-2 kW were carried out at the Institute of Power Engineering and Fluid Mechanics of Wrocław University of Technology since the early 1990s. Then the test stand of the ORC using as expander vane rotary machine was designed and built. Working medium was R-11. At the test stand, series of experiments were carried out, and the results have been collected by Mr Stanislaw Biernacki in his PhD thesis. The need for the withdrawal of R-11 from use was associated with the exploration of new working mediums and analysis of their property and properties of thermodynamic systems using different rotary vane expanders. New organization of a low potential heat conversion process to mechanical work has been proposed. Also the methodology of working medium selection has been designed. That methodology was then developed by Dr. ing. Piotr Kolasiński. CHP ORC systems that can be used in households and small workshops were designed, analyzed and tested. Works in ORC area are still carried out.
