Refrigeration systems are extremely important in daily life, especially in terms of preserving food, health, and comfort. The objective of this project work is to make some effective changes in the design of a conventional refrigerating system so that performance of the evaporator can be optimized. The effects of the normal and perforated fin on the velocity and temperature distribution at different levels. To make a comparative analysis between various cases of with and without the fin refrigerating system. The analysis and modeling through CFD for refrigerators based on diffusion-absorption is presented as a feasible tool for the purpose of evaluating proposals in the internal design of the refrigerator. The present study considers that significant improvements can be achieved on the thermal profiles, by researching an optimal geometric plate-evaporator, in which the airflow is included as a parameter of great importance in the operability of the refrigerator and therefore, in the preservation of food supplies
