Abstract

A few correlation equations of the saturated liquid density are reviewed and a new equation is proposed. Performance of each equation is examined using the data listed in the ASHRAE table for 22 pure substance refrigerants. The new four-parameter equation yields an average absolute deviation of 0.03% for 22 refrigerants. Performance of the new four-parameter equation is found to be equivalent to those of the existing equations such as Hou-Martin equation(0.03%) and Iglesias-Silva-Hall equation(0.08%).
