The selection of suitable organic fluids for use in Organic Rankine Cycle (ORC) for waste energy recovery from many potential sources of low-medium temperature (up to 350 ºC) 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; from the thermophysical properties of the fluids leading to the environmental impact and cost related issues. The aim of the study is to elaborate a tool for the 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 as well as a software (code) which allows the user to select the proper organic fluid for particular application have been developed. Calculations have been conducted for the same heat source and installation component 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.
