ShareTwo-phase flow condensation heat transfer and pressure drop characteristics of HCFC22 and AZ20.
Author(s) : WIJAYA H., SPATZ M. W.
Summary
The paper presents the two-phase condensation heat-transfer coefficient and pressure drop characteristics of R22 and AZ20 (an azeotropic mixture of 50-50% by weight of R32-R125). The experiments were conducted without oil in the refrigerant loop. The results showed that at similar mass fluxes the condensation heat-transfer coefficients for AZ20 were slightly higher (about 2 to 6%) than those of R22. However, the pressure drops for AZ20 were significantly lower (about 25 to 45%) than those of R22.
