Abstract The development of electric vehicles (EVs) exhibits rapid and remarkable progress nowadays, serving as a crucial route to accomplish the target mitigating greenhouse gas emissions. As an integral part thermal management system oriented toward vehicles, heat pump air conditioning for is result comprehensive choice that trades off cooling heating performance, environmental performance economic cost. Particularly, different regions around world suffer varying challenges due complicated climatic characteristics. Thus most suitable refrigerant cycle structure may differ. This paper focuses on evaluating both refrigerants structures screen choice. According climate conditions cities, annual energy consumption, life cost basic (Base), two-stage compression (TSC,IC), vapor injection (VI) with CO 2 , R134a, R1234yf respectively, are quantitatively analyzed evaluated. Subsequently, through comparative analysis, selection map systems in worldwide developed each cites determined. results can provide reference decision-making from regional considerations. It was found HPAC VI recommended cold meet requirements. In warm region, Base be used. For transitioning climates, suggested. hot AC recommended.
