Caractéristiques de transfert de chaleur et performances des échangeurs de chaleur au R407C munis de tubes de transfert de chaleur à rainures intérieures en chevrons.

Heat transfer characteristics and heat exchanger performances for R407C using herringbone heat transfer tube.

Résumé

The new advanced heat transfer tube called "herringbone heat transfer tube", having a unique inner surface geometry, have been experimentally investigated with R407C. Experimental examinations have been done to obtain the air-cooled heat transfer coefficient and pressure drop for R407C flowing inside the horizontal herringbone tube; the heat transfer coefficients for the herringbone tube have been verified to be much superior to the existing inner grooved tube, but the significant increase in heat transfer has been accomplished with an increase in pressure drop. More information is given.
