A radial turbine Received in revised form directly connected to the high-speed synchronous generator was also designed and developed. R245fa 16 January 2012 was adopted as a working ?uid, in consideration of the operation conditions of the cycle and its Accepted 16 February 2012 environmentally-friendly characteristics. Experiments were conducted to analyze the operational char- Available online 22 March 2012 acteristics and performance of the developed ORC. The ef?ciencies of the cycle and the turbine, electric power of the developed ORC with respect to the operation conditions were investigated in a series of Keywords: ? ORC (Organic Rankine cycle) experiments. The factors which in uence the performance of the developed ORC were analyzed and R245fa
