An experimental study is conducted to investigate the performance of a low-temperature solar recuperative Rankine cycle system using working fluid R245fa. The experimental setup consisted of typical Rankine cycle components, such as throttling valves, working fluid pumps, air cooled condensers,...

The paper presents an on site experimental study of a low-temperature solar Rankine cycle system for power generation. The cycle performances of pure fluid M1 (R245fa) and zeotropic mixtures M2 (R245fa/R152a, 0.9/0.1) and M3 (R245fa/R152a, 0.7/0.3) are compared, respectively, based on the...

A kilowatt-sized rolling-piston expander is proposed for low-temperature Organic Rankine Cycle power generation system. The main purpose of this paper is to conduct a dynamic test of the proposed expander. A low-temperature ORC system using R245fa as working fluid is established for the...
