This research presents experimental results on convective heat transfer coefficients for the refrigerants R410A, R32, R22, and propane during condensation within a multiport mini-channel tube. The experiments were carried out under controlled conditions with an average saturation temperature of 48°C and a mass flux ranging from 50 to 300 kg/m²s. The findings indicate a direct relationship between mass flux and heat transfer coefficient across all tested refrigerants, with propane demonstrating the highest heat transfer coefficient followed by R410A, R22, and R32. These new correlations showcasing predictive performance with a maximum deviation of less than 15.3% from experimental values. This study offers valuable insights for the design and enhancement of mini-channel multiport heat exchangers employing refrigerants such as R410A, R32, R22, and propane.
