In this study, An optimization algorithm was used to obtain the constant parameters of the new empirical model by fitting them to the source databank. The model was used to calculate the constant coefficients of the new equation for 15474 data of 27 refrigerants (temperatures between 92 and 486 K) by fitting them with source data. The accuracy of the presented equation was compared with commonly used models. Results indicated that the developed model provides more accurate results than those of other considered equations, with an average absolute percentage deviation of 3.46%. %U https://www.physchemres.org/article_81462_3986626be091450532fb29fba356851f.pdf
