有机朗肯循环（ORC）是工业部门中100 - 300 ℃之间未使用热能的有效利用方法，从高效率的角度来看，它被选中。对1 kW级风冷紧凑型ORC发电系统样机进行了冷凝器环境温度和膨胀机吸气温度变化的评估。在实验结果中，在膨胀机吸入温度为175 °C、冷凝器环境温度为20 °C的情况下，膨胀机的发电功率为1,027 W，总发电效率为10.3%。考虑到泵和风机等辅助设备的输入功率，净发电效率为9.0%。在能量平衡分析中，泵和风机的功率消耗很小，几乎所有的发电功率都被有效利用。
As the effective utilization method of unused heat energy between 100 and 300 degree-C in the industrial sector, Organic Rankine Cycle (ORC) was selected from the viewpoint of high efficiency. The prototype of air-cooled compact ORC electric power generation system for 1kW class was evaluated in variation of the ambient temperature of condenser and the suction temperature of expander. In the experimental results, at the expander suction temperature of 175 °C and the ambient temperature of 20 °C for condenser, the generated power by the expander is 1,027W and the gross power generation efficiency is 10.3%. The net power generation efficiency, considering the input power of auxiliary equipment such as pumps and fans, is 9.0%. In the result of energy balance analysis, power consumptions of the pump and the fan are small and almost of the generated power is effectively available.
