Study on The Two Level of Organic Rankine Cycle Applied to Mine Vehicle Exhaust Heat Recovery System

Abstract

The thermodynamic system model is established in this study. Using R123 as refrigerant, in different refrigerant evaporation temperature and expansion ratio under the condition of thermal performance of two organic Rankine cycle system and ordinary organic Rankine cycle system is analyzed in the paper. The research shows that the two level of organic Rankine cycle system has obvious advantages of high heat utilization rate and the better heat recovery effect.
