低GWP制冷剂在新能源汽车空调应用性能分析
Performance analysis of low GWP refrigerant used in new energy vehicle air conditioning
摘要
Abstract
With the formal enforcement of the Kigali Amendment,the use of R134a in future vehicle air conditioning systems will be restricted due to its high global warming potential(GWP).To study the feasibility of low GWP refrigerants as replacements,this study first conducts a thermodynamic performance analysis and multi-factor evaluation of R1234yf,R1234ze(E)and R290 across four actual automotive operating conditions,with comparisons to R134a.Additionally,a range model is developed to assess the range performance of these refrigerants under varying winter ambient temperatures.The results indicate that R1234yf has a similar volume cooling/heating capacity and compatible compressor displacement when compared to R134a.The coefficient of performance(COP)and cooling/heating effectiveness of R1234ze(E)are also found to be comparable to those of R134a.In extreme cold winter conditions,R290 demonstrates a notable performance advantage,with COPh and qcv that are 2.3%and 57.3%higher than R134a,respectively.Furthermore,under heat pump operating conditions,R290 shows a slower rate of range decay compared to R134a.This study provides valuable insights into the substitution and application potential of efficient and environmentally friendly refrigerants in the field of vehicle air conditioning.关键词
