摘要
Abstract
Organic Rankine cycle (ORC) system uses organic fluids as working fluids to promote the work of the turbine.It performs better in recovering low enthalpy containing heat sources.The thermodynamic properties of working fluid have a significant effect on performance of solar organic Rankine cycle (ORC).According to the collector temperature of 120℃,and the evaporation temperature of 100℃,this article took R245fa,R123,R236fa,R113,R245ca,R600 and R601 as candidate working fluids,during which the evaporation temperature,thermal efficiency,exergy efficiency and total irreversible loss were respectively calculated and compared by using Matlab and PERPROP softwares.The results show:R123 performs relatively high thermal and exergy efficiency and produces relatively low total irreversible loss in low temperature solar ORC system,which is recommended as a desirable working fluid for the ORC system of evaporation temperature below 100℃.关键词
