    (LACCEI Inc., 2020-07) Hermosa, Freddy; Tasiguano, Cristian; Pozo, Marcelo; Acurio, Eliana
    This work presents the control design of a domestic refrigeration system by using a variable speed compressor(inverter technology) with the main purpose of reducing energy consumption and complying with Ecuadorian standards for this type of household appliances. A study on refrigeration systems is carried out, its operating principles are discussed and a comparison between conventional systems and the variable speed technology is performed. Additionally, an analysis of the refrigeration control is included and the variable speed controller is implemented in a prototype card, which was installed in a domestic R12 refrigerator. The system exhibits a reduction of 27% in the consumption test regulated by the RTE INEN 035 and the NTE-INEN 2 206 norms, which demonstrates its high energy efficient performance.
