Résumé

This work presents a set of numerical studies, for a light commercial freezer, about the influence on the performance of some design parameters. In particular, the influence of the combination of charge-capillary tube diameter has been analyzed. The results do not only analyze parameters related with the energy consumption but with other operation parameters. The results are shown in two dimensional maps for each parameter. These maps have the enormous advantage to provide detailed and important information regarding the sensitivity of the system to variations of the refrigerant charge and capillary tube diameter allowing, therefore, to determine their absolute optimum values. Moreover, the current trend to replace the synthetic refrigerants with natural fluids, has suggested the realization of simulations aiming at determining the performance of the system with different refrigerant fluids. It has been compared the performance of the application running with R600a, R600, R290 and R134a. Results show that for this application the propane has the best performance in terms of COP with a reduced charge.
