This study investigates the dehumidification and heating performance of a dual‑evaporator heat pump system for electric vehicles,which operates in two modes:Single‑evaporator mode (SEM) and dual-evaporator mode (DEM).Experimental evaluations were conducted under varying operating conditions to compare system characteristics.Results demonstrate that at 60%~90% inlet air humidity and 4 000 r/min compressor speed,SEM achieves 26.2%~62.8% higher dehumidification rates and 25.7%~43.9% greater DSMER than DEM. Conversely,DEM exhibits 26.6%~67.6% superior effective heating capacity and 11.2%~50.0% higher COP compared to SEM.When maintaining equivalent dehumidification performance,DEM delivers 43% higher outlet air temperature and 28% improved COP over SEM. These findings provide critical insights for expanding application scenarios of electric vehicle heat pump systems and advancing their technological development.
