Starting performance comparison of R290 and R32 air conditioning systems under extreme cold conditions in Mohe China

Abstract The global phase-down of high-GWP refrigerants necessitates a transition to sustainable alternatives like R290 (GWP = 3) and R32 (GWP = 675). However, their dynamic startup reliability in extreme polar climates remains poorly understood. This study experimentally investi...
