This article analyses the ORC system working with dry and wet low-boiling media, which are most frequently used in installations of this type. Two types of cycles were examined: the cycle with heat regeneration for dry media (fc72, hfe7100, R227ea, R245fa, R423a, and R600a) and the cycle without heat regeneration for wet media (R11, R12, R134a, R718, and 507a). The calculations were performed for the assumed required thermal power Q=50 kW and two variants of low-boiling medium temperature equal to t=50 and 95ºC at condenser inlet. The effects of medium type and parameters on basic design parameters of the axial micro turbine also were analyzed.
