[Display omitted] This work is a computer-aided methodological description for the rapid and objective analysis of the performance criteria of an absorption refrigerator. It can be used as a tool for a simulation platform to improve the parameters for the optimal operation of the present system. Sometimes, some of the obstacles of the original method related to the analysis of the performance criteria of absorption machines may come from the number of equations and the complexity of the calculation of NH3 mass fraction of NH3-NaSCN solution. The method consists of a characteristic matrix that allows to quickly determine the NH3 mass fraction of NH3-NaSCN solution in relation to the performance criteria: COP (coefficient of performance), ECOP (exergetic efficiency) and CR (circulation ratio).This could facilitate the algorithm and the direct calculation of NH3 mass fraction of NH3-NaSCN solution in contrast to the original model. For this reason, an easily reproducible flow chart has been proposed.•Transformation of complex mathematical models into easy to code models.•Elaboration of a characteristic matrix for the determination of concentrations.•Development of a platform for the simulation of performance criteria.
