Description

An experimental study on the heat transfer characteristics of two-phase flow condensation and boiling of ternary nonazeotropic refrigerant mixtures on air/refrigerant horizontally enhanced surface tubing is presented. Correlations are proposed to predict heat transfer characteristics such as average heat transfer coefficients, as well as pressure drops of ternary nonazeotropic refrigerant mixture flow condensation and boiling inside enhanced surface tubing. In addition, it was found that the pressure drop of the refrigerant mixture is a weak function of the mixture’s composition.
