An analytical model of condensation heat transfer of non-azeotropic refrigerant mixtures in a horizontal tube.

Author(s) : LU D. C., LEE C. C.

Summary

The composition of the axial vapour flow is found to approach that of the more volatile component in the downstream region of the condenser. A one-dimensional model of the condensation of non-azeotropic refrigerant mixtures in a horizontal tube is then formulated in which an annular flow pattern is assumed. Energy and mass balances as well as heat and mass transfer equations are presented for the axial vapour flow and the condensate liquid flow, respectively. The local diffusion flux in the liquid condensate is found to have little effect on the local condensed mass flux.
