Refrigeration is of fundamental importance in the development of human beings over the years. Within this scope, diverse applications are included, from the manufacture of food, its conservation, environment refrigeration and even applications in electronic equipment. In view of the great importance and great impact of this branch of engineering within the sustainable development of humanity, an objective research is carried out with the aim of carrying out a study regarding the relationship between an operation of the electric compressor that constitutes a refrigeration system and its energy efficiency. The work consists of literature reviews that aim to obtain a model that describes the behavior of variables in a refrigeration system. Then, the implem entation of the thermodynamic model in Simulink is performed. Then, it starts to deduce the mathematical equations that govern the behavior of the induction engine, so that a script can be generated in the Matlab, thus allowing the simulation of the engine for different operating regimes. At the end of the work, the interaction between the thermodynamic and electrical models of the three-phase inducction motor ( MIT) is performed, thus enabling the obtaining of results for different modes of motor drive, comparing the consumption and performance of the machine between them. |
