R502 and two near-azeotropic alternatives. 1. In-tube flow-boiling tests.

Author(s) : KATTAN N., THOME J. R., FAVRAT D.

Summary

In-tube flow-boiling experiments for two new zeotropic, three-component refrigerant mixtures (R402A and R404A) and R502 have been carried out. Comparative results show that local flow-boiling heat transfer coefficients for R404A are slightly larger than those for R502 under the same test conditions, while those for R402A are on average slightly smaller. The heat transfer performances of the three fluids are accurately predicted by an existing flow-boiling correlation modified here to include an analytical, mass diffusion mixture boiling equation.
