ABSTRACT
One of the key challenges on the area of energy engineering is the system developinent for increasing the efficiency of primary energy conversion and use. Froin this perspective, low-and iniddle temperature heat as waste heat from various processes is becoming more and more "attractive" as a secondary energy source. One candidate suitable for improving efficiencies of existing applications and allowing the extraction of energy froin previously unsuitable sources is the Organic-Rankine-Cycle.
Applications based on this cycle allow the use of low temperature energy sources such as waste heat from industrial applications, geothermal sources, biomass fired power plants, micro combined heat and power systems and others. The selection of suitable organic fluids for use in Organic-Rankine-Cycle for waste energy recovery from many potential sources of low-medium temperature is a crucial step to achieve high thermal efficiency. In order to identify the most suitable organic fluids, several general criteria have to be taken into consideration. The aim of the study is to elaborate a tool for tlie
comparison of the influence of different working fluids on performance of an ORC heat recovery power plant installation. A database of a number of organic fluids which allows the user to select the proper organic fluid for particular application has been developed. Calculations have been conducted for the same heat source and installation coinponent parameters. The elaborated tool should create a support by choosing an optimal working fluid for special applications and become a part of a bigger optimization procedure by different frame conditions.
The system efficiency is the main goal when designing heat recovery systems, but at the same time the environmental characteristics have to be taken into account for safety and practical considerations. Although at this moment the
sorting criterion for the fluids is the system efficiency, further development of the proposed program will create the possibility for different sorting criteria.
