Abstract
In order to improve the thermodynamic performance of the Supercritical organic Rankine cycle (SORC), the regenerative supercritical organic Rankine cycle with an injector (RORC) is presented. For the moderate temperature of waste heat, the thermodynamic performance of RORC and SORC are investigated by using the working fluid R123. The effects of extraction pressure, expander inlet temperature, expander inlet pressure and condensing temperature on the net power output and the thermal efficiency have been analyzed. The net power output of RORC is greater than one of SORC when the extraction pressure is lower than 0.45 MPa. When the extraction pressure is 0.6 MPa, the efficiency of RORC reaches the maximum (16.06%), which is 0.66% higher than one of SORC. This reveals that the performance of RORC is better than that of SORC.
