纯电动车热管理系统低GWP工质替代方案性能分析与综合评价
Performance analysis and comprehensive evaluation of thermal management system schemes with low GWP refrigerants
摘要
Abstract
To ensure energy security,reduce pollution and combat global climate change,the automotive industry is rapidly shifting from conventionally fuelled vehicles(CFVs)to zero-emission pure electric vehicles(BEVs).A sophisticated,reliable and efficient vehicle thermal management system is essential to enhance BEV performance and alleviate range anxiety.As environmental regulations become increasingly stringent,the selection of low global warming potential(GWP)refrigerants for thermal management systems has become a pressing sustainability issue.The study establishes a numerical simulation platform for the thermal management system of a complete vehicle and selects low GWP alternative refrigerant schemes such as R744,R290,R152a and R1234yf.The basic performance differences between these refrigerant schemes are investigated,and the thermodynamic and environmental performance of each scheme is evaluated to establish a comprehensive evaluation system.The study shows that the R744 option has the highest heating capacity of 27.5 kW,R290 performs better in terms of cooling and heating efficiency,with an average energy consumption of 5%to 7%lower than that of the R134a option,and the R290 option exhibits excellent thermodynamic performance and environmental friendliness.A comprehensive evaluation shows that the R290 and R744 options are promising refrigerant choices for future BEV thermal management systems.关键词
