Heat transfer coefficients for propane (R-290), isobutane (R-600a), and 50/50 mixture of propane and isobutane
Tube-side heat transfer coefficients for single-phase flow, evaporation, and condensation are presented for propane (R-290), isobutane (R-600a), and a 50/50 mixture (by weight) of propane and isobutane. Heat transfer coefficients have been presented for smooth tubes. The correlations for evaporation...

| description | Tube-side heat transfer coefficients for single-phase flow, evaporation, and condensation are presented for propane (R-290), isobutane (R-600a), and a 50/50 mixture (by weight) of propane and isobutane. Heat transfer coefficients have been presented for smooth tubes. The correlations for evaporation and condensation have previously been verified for R-12 and other refrigerants. The mass flux of the refrigerant is varied over a wide range that is typically encountered in residential, commercial, and automotive applications. The REFPROP computer program has been used to determine the thermodynamic properties for R-290, R-600a, and R-290 /R-600a. This study shows that the heat transfer coefficients for hydrocarbons are significantly higher than hose for both R-12 and R-134a. A summary of the heat transfer coefficient enhancement of the hydrocarbons in comparison to both R-12 and R-134a is presented in tables. |
