Experimental study of an integrated organic Rankine cycle system under isolated network operating condition
摘要
Abstract
The test results of a 10kW integrated organic Rankine cycle (ORC) system with R245fa as the working fluid under isolated network operating condition were presented in this paper.A single screw expander was integrated in the system to drive the synchronous generator to generate electric power.The 10.5kW halogen lamp array was used as the load to consume the generated electric power.Two independent parameters,the load capacity and the expander speed,were varied during the test.The ORC system characteristics were analyzed at the heat source temperature of 115 ℃.The experimental data showed that the single screw expander performed very well.The maximum expander isentropic efficiency was 84.1%,which decreased with increase of load and expander speed.The maximum isentropic efficiency of working fluid pump was 73.97%,which increased with the increase of load and expander speed.The mechanical efficiency of the working fluid pump was only 19.22%-36.82%,and had no obvious relationship with the load and the expander speed.The generated electric power increased with the increase of load and expander speed.The maximum generated electric power and the electrical efficiency were 5.86kW and 7.38%,respectively.关键词
