Saturated vapour condensation of R410A inside a 4 mm ID horizontal smooth tube: Comparison with the low GWP substitute R32

•This paper investigates R32 and R410A condensation inside a smooth tube.•The transition between gravity-controlled and forced convection condensation occurs in the range of Reeq 10,000–20,000.•R32 exhibits heat transfer coefficients and frictional pressure drops higher than R410A.•R32 is a very pro...
