The operation characteristic of an Organic Rankine Cycle using R123 and a scroll expander have been investigated.
- class="label">•
The behaviors and detailed discussion for those four major components are examined.
- class="label">•
The expander isentropic efficiency presents a slight decrease first and then a sharp increase with mass flow rate.

The maximum electrical power and system generation efficiency are 2.01 kW and 3.25%, respectively.
