Résumé

Heat transfer coefficient and pressure drop were measured for condensation and evaporation of R410A and R22 inside internally grooved tubes. The experiments were performed for a conventional spiral groove tube and a herring-bone groove tube. To measure the local heat transfer coefficients and pressure drop, the test section was subdivided into four small sections. The obtained heat transfer data for R410A and R22 indicate that the values of the local heat transfer coefficients of the herring-bone grooved tube are about twice as large as those of spiral one for condensation and are slightly larger than those of spiral one for the evaporation. The measured local pressure drop in both condensation and evaporation is well correlated with the empirical equation proposed.
