ShareCorrelation of evaporative heat transfer coefficients for refrigerant mixtures.
Author(s) : SHIN J. Y., KIM M. S., RO S. T.
Summary
On the basis of the measured evaporative heat transfer coefficients for pure refrigerants (R22, R32, R125, R134a, R290, and isobutane) and refrigerant mixtures (R32-R134a and R290-isobutane) in a horizontal tube, a correlation of evaporative heat transfer coefficients for refrigerant mixtures is developed. An analysis of evaporative heat transfer is performed for an annular flow of refrigerant mixtures. Correction factor is introduced to the correlation for refrigerant mixtures. The evaporative heat transfer coefficients are calculated using the correlation considering nucleate boiling effect in the low quality region and mass transfer effect for zeotropic refrigerant mixtures.
