Medium selection of organic Rankine cycle(ORC) in low temperature waste heat
摘要
Abstract
Most studies on organic Rankine cycle (ORC) mainly focused on the thermodynamic properties of working medium. Pinch analysis method used commonly may lead to different evaluation criteria in different medium. This paper preselected fluids by their properties in the consideration of environment protection,safety and stability to solve the problems mentioned above. Fourteen types of working fluids were selected and screened by the thermodynamic and economic properties,and the optimal working fluid was obtained using Matlab and Refprop simulation. The working substance evaluation standards were unified according to the properties of unit power required for UA and mass flow rate. The results showed that most alkane substances had higher thermal efficiency,compression ratio and lower mass flow. The cyclohexane was an ideal circulating working fluid with higher thermal efficiency,lower mass flow rate and appropriate pressure ratio in the low temperature waste heat system.关键词
