Retrofit de sistema de refrigeración comercial mediante racks de compresores con refrigerantes sostenibles

Abstract

This work proposes a project management methodology aimed at modernizing refrigeration systems in supermarkets, focusing on the transition to refrigerants with a low Global Warming Potential (GWP), thereby reducing their environmental impact. Currently, many systems have operational deficiencies and use hydrofluorocarbon refrigerants, which have an extremely high carbon footprint that translates into a high global warming potential. The solution integrates a detailed technical approach, a structured execution process, and refrigerant replacement, applying a cascade methodology based on document analysis, technical analysis, and sequential phased control. As part of the implementation, a compressor rack was installed that integrates medium- and low-temperature systems, achieving optimal refrigeration and freezing performance through the adoption of sustainable refrigerants (CO₂ and a water-glycol mixture as a secondary fluid), with energy savings of 24%. Additionally, a remote monitoring system was incorporated for real-time control, optimizing processes, ensuring operational efficiency, and improving system reliability.
