The project addresses the challenge of purifying indoor air supply in a complete and efficient manner. The system in addition filters the air,driven by two fans, efficiently, eliminates microorganisms that cause disease from the proven action of radiation from the LED lights of the UV-C type. Using water and carbon dioxide in the environment as raw materials, the system increases oxygen levels using the electrolysis process. All of this with a DC current powered by solar panels, aiming to reach the target audience of people without access to electricity.
According to the World Bank, 840 million people worldwide do not have access to electricity. In addition, in 2030, around 674 million people in the world will remain without access to electricity, with the maintenance of the population growth rate and policies to expand access to energy. Our main goal is to reach a significant percentage of this population group, searching for the improvement of well-being and quality of life, in addition to reducing the incidence of health problems. With that in mind, we have developed an innovative, affordable and low-cost solution through a combination of existing technologies. We developed the project with a multidisciplinary team, focused on engineering. We use engineering tools like Siemens NX 12, Siemens Star CCM+ 15,Altium Designer PCB, and Matlab 2017 B. We use design tools like Golden Circle, Business Model Canvas, FMEA and DFMEA and Boundary Diagram. The pitch design was made using Adobe Premiere CC Pro.
Throughout the entire project, we used NASA linked studies in an objective way, seeking to validate the key points of our project.To identify and develop the product's gaseous volume, fluid dynamic analyzes were performed using the Star CCM 15 software, with a rotation of 2500 rotations per minute in the fans. The filter was characterized as a porous region, allowing restricted air flow. The resulting parameters were obtained 8.47 cubic meters per hour of filtered and purified air.
