Abstract—This paper describes the experimental efficiency of a below. Therefore, it is important to develop an economically
compact organic Rankine cycle (ORC) system with a compact
rotary-vane-type expander. The compact ORC system can be used for efficient waste heat recovery system that can generate power
power generation from low-temperature heat sources such as waste and/or electricity from low-temperature heat sources (less than
heat from various small-scale heat engines, fuel cells, electric devices, 100°C). Furthermore, the recovery system must have a compact
and solar thermal energy. The purpose of this study is to develop an
size because waste heat is a highly distributed energy source.
ORC system with a low power output of less than 1 kW with a hot
temperature source ranging from 60°C to 100°C and a cold The power generated by the recovery system would be less
