Abstract

This project addresses the problem of high costs and limited availability of specialized equipment for automotive air conditioning workshops. The main objective was to design and build a multifunctional, economical, and efficient refrigerant gas recovery unit that would integrate the functions of gas recovery, vacuum generation, and pressurized air injection into a single unit. The unit is characterized by its construction with recycled and low-cost materials, utilizing components such as reused compressors and adapted tanks. This approach significantly reduces the required investment compared to commercial equipment. The design consolidated three critical maintenance tasks into a single device, optimizing workflow and reducing downtime during technical interventions. The development followed an applied engineering methodology, prioritizing criteria of functionality, safety, and sustainability. Validation tests demonstrated proper operation in four critical operations: generating a vacuum in the system, recovering and storing refrigerant gas, injecting air for leak detection, and recharging the recovered refrigerant. The project demonstrates the possibility of manufacturing low-cost, specialized equipment that improves efficiency in automotive workshops.
