ShareHeat exchange: laws on transfer and pressure loss. Comparison of R22 and R407C.
Echangeurs de chaleur : lois de transfert et de perte de pression. Comparaison des fluides R22 et R407C.
Author(s) : MARVILLET C., BONTEMPS A., BERRADA N., SIGNE J. C.
Summary
The paper presents the main results obtained at GRETh on the laws dealing with phase-change transfer of zeotropic blends in the most common operating conditions, ie, evaporation and condensation inside a horizontal tube, and condensation in a bundle of tubes equipped with smooth tubes or fins. In a future work, the authors plan to compare the thermal performances of R22 and R407C.
