Summary

This paper presents the heat-transfer assessment of different low GWP substitutes for traditional R245fa as a working fluid for ORC. The assessment is carried out by applying a theoretical analysis based on specific Performance Evaluation Criteria (PEC), the Penalty Factor (PF) and the Total Temperature Penalisation (TTP), in the specific case of boiling and condensation inside smooth and microfin tubes. The results of the assessment confirm that the refrigerants R1233zd(E), R1234ze(Z) and R1224yd(Z) have comparable heat transfer characteristics to R245fa. The use of theoretical assessments tuned on experimental measurements provides a sound procedure for the perform
