A paper has been published in the International Journal of Refrigeration by D. Kumlutas et al. [Int. J. Refrigeration 35, 1678-1689, 2012], which investigates design parameters of a conventional domestic refrigerator using Artificial Neural Network (ANN) simulations. The present paper attempts to discuss and comment on the above paper namely, the lack of detailed information about the design parameters of subjected refrigerator, test configuration, analysis criteria, equations and the results of solving the radiative heat transfer.
