Analysing selection of low-temperature medium for cogeneration micro power plant

Abstract

The 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, which were 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 95 ℃ at condenser inlet. The effect of medium type and parameters on basic design parameters of the axial micro turbine was also analysed.
