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.EnglishLACCEI Licensehttps://laccei.org/blog/copyright-laccei-papers/BLDCefficiencyinverterON/OFF controlPI controllerrefrigerationArticle
