Abstract

A novel pumpless organic Rankine cycle(ORC) system is designed and established. The electrical pump for pressurizing and transporting the working fluid is replaced by two vessels and a group of valves. The heat source of 106.3~127.9°C and cooling water of 20°C are adopted for heating and cooling processes. The results indicate that the parameters such as pressure and temperature are fluctuated periodically with time, while the shaft power and the efficiency of the system increase with heat source temperature. The maximum average shaft power, thermal efficiency and exergy efficiency are 104.3W, 2.6% and 13.0%, respectively, when the heat source temperature and evaporation temperature are 127.9 °C and 52.0°C, separately. Furthermore, the novel system has a significant improvement in the continuity and stability of shaft power with a relative fluctuation reduction of 80.6% compared to the existing pumpless ORC system.
