Simulation dynamique de l'atmosphère contrôlée (AC) des systèmes d'entreposage frigorifique pour les fruits à pépin.

Dynamic simulation of controlled atmosphere (CA) cool storage systems for pip fruits.

Résumé

Simulation of dynamic processes in controlled atmosphere cold-room storage systems is presented. The model consists of three interacting sub-models, for the prediction of the transient behaviour of the processes in the three units, namely, the cold room, the refrigeration system and the gas-handling unit. Several modules representing each of the components in these units were developed based on energy and mass balances. The modules were then arranged to form the sub-models and in turn, the global CA cool storage system model was formulated by interconnecting these sub-models. The modules are implemented in a computational environment (EcosimPro), which can handle continuous and discrete events. Due to the modular and object-oriented approach greater flexibility with respect to model modification and reusability is achieved. Simulation of several cool rooms (CA) loaded with different products is possible by using the model. Further, tuning of controller parameters can be carried out to improve performance of the cold rooms. In the paper, the model predictions were compared with experimental results. In general, good agreement between model predictions and measured values was obtained. Moreover, the provided product respiration model enables easy coupling to product quality models to predict the quality deterioration of the stored products during storage.
