ZAMORA-MEDINA, Janeth Roxana; BRIONES-REZABALA, Luis Rene; ARTEAGA-LINZAN, Ángel Rafael  e  RODRIGUEZ-RAMOS, Pedro A.. Determining the availability of an industrial refrigeration system for the tunny industry. Ingeniería Mecánica [online]. 2022, vol.25, n.2, pp. 1-8.  Epub 09-Set-2022. ISSN 1815-5944.

The refrigeration systems in the food industries are of great relevance for the conservation of the quality and safety standards of the raw materials, for this reason, the present work had as objective the determination of the availability and the operational life stage of a refrigeration system of an tuna industry. The methodology used was the Weibull distribution model and the method of least squares for the determination of the Weibull shape and scale parameters. The results of the calculation of the Weibull parameters allowed us to know that the availability of chamber 1 and 2 of the studied system were 97 % and 90 % respectively, in addition, the values ​​of the shape parameter were identified by using the Davies curve. 0.6936 and 1.0673, which indicated that chamber 1 was in a period of initial failures and chamber 2 in a stage of wear due to aging. Finally, it was concluded that chamber 1, being in an initial stage of operation, did not show significant damage to its components and had greater operational availability.
