چکیده

This work presents a new simple equation for the thermal conductivity of liquid refrigerants as a function of the reduced temperature, molecular mass, reduced pressure, and the acentric factor. This model is applied for predicting the thermal conductivity of the refrigerants over the whole temperature and pressure ranges. A set of 915 data on the thermal conductivity for 30 refrigerants has been used. These refrigerants were divided into three categories on the basis of various chemical halogens forming the compounds and were investigated individually. For the data sets, the average error of the proposed model was 4.82%. The results show that the new equation can be used with confidence in engineering calculations
