The application of Artificial Neural Networks (ANNs) for prediction of thermodynamic
properties of refrigerants in vaporeliquid equilibrium is the scope of this article. It is very
important to find new ways to calculate thermodynamic properties of new refrigerants to
simplify equipment operation and design. ANNs are capable of learning the complex relationships
between input and output data, therefore they can be a good replacement of
the commonly used Equations of State (EoS) for thermodynamic properties prediction. In
this work multilayer perceptron ANNs with back-propagation algorithm were employed to
obtain accurate thermodynamic properties prediction models. No EoS were needed so far.
ANNs show their ability to accurately predict properties of refrigerants opening a promissory
way to process optimization and construction of intelligent devices, impacting in
both cost and energy savings
