ROJAS-GALLARDO, Carlos Alberto; CANO, Ruth  and  GARCIA-MELO, José Isidro. Modelling of secondary cooling system with a distributed architecture, using Coloured Petri nets. Antioquia [online]. 2019, n.91, pp.83-94. ISSN 0120-6230.

Currently, cooling systems adjust their control structures with the objective of satisfying the demands of different applications. In consequence, the centralized structure frequently used in this type of applications has evolved towards a distributed structure to increase the quality of response to the current demands of the market. However, a correct specification of this type of structure demands several challenges to be overcome, such as the management of specialized resources, integration methods, coordination of independent subsystems, clarity of information, and increased dynamics of systems. This study addressed the modelling of the secondary cooling system that is located in the refrigeration laboratory of the School of Mechanical Engineering at the Universidad del Valle in Cali, Colombia. A distributed structure was considered by the integration of several modelling tools, such as Coloured Petri nets. Using the structural model and successive refinements, the system behaviour representation was obtained.

Keywords : Coloured Petri nets; discrete event system; modelling.
