Résumé
In this paper, M1(R32/R290, 67/33) and M2(R32/R1270, 63/37) were proposed to replace R410A refrigerant. The thermodynamic parameters of R410A, M1 and M2 were compared, the effects of mass flux, vapor quality and physical properties on heat transfer performance were discussed. The results showed that the thermodynamic performances of M1 and M2 are similar to R410A, which GWP were 76.3% and 77.8% lower than that of R410A, respectively. At the same condition, the heat transfer coefficients and pressure gradients increase with increasing mass flux and vapor quality, the heat transfer coefficients of M1 and M2 were on average 13% and 17% higher than that of R410A, respectively. However, the pressure gradients of the three are not much different. M1 and M2 can be used as low GWP alternative refrigerants of R410A. The obtained results of the present study are of great significance to the industrial application of alternative refrigerants.
