R‐152a achieves the highest COP of 2.92 and the lowest TEWI, indicating exceptional performance for heating.
Cold climate heat pumps using R‐290 and R‐152a show significant volumetric heating capacities around 3.2 to 3.78 MJ/m³.
The analysis utilizes thermodynamic and exergy frameworks, highlighting MCDM for refrigerant selection.
Framework supports transitioning to climate-friendly refrigerants, with implications for environmental sustainability.
