Abstract

A few commonly used correlation equations of the enthalpy of vaporization are reviewed and a new three-parameter correlation equation is proposed. Performance of the proposed equation is examined using the data listed in the ASHRAE table for 22 pure substance refrigerants. The new equation yields an average absolute deviation of $0.14\%$ for 22 refrigerants, which is better than those of other equations, such as Xiang $(0.18\%),$ Majer-SvobodaPick $(0.18\%),$ and Somayajulu equation $(0.23\%)$ .
