Summary

The heat-transfer behaviour of two ternary refrigerant blends proposed as R12 substitutes, has been studied during condensation and boiling inside horizontal enhanced surface tubing. Correlations are proposed to predict the average heat transfer coefficients as well as pressure drops of newly proposed ternary refrigerant blend flow, inside enhanced surface tubing.
