ENERGY AUDIT OF A P AINT BOOTH
Abstract
La energía es clave tanto para el crecimiento económico como para el bienestar de los ciudadanos. Sin embargo, el aumento previsto de la demanda energética ha hecho de la reducción de su consumo una prioridad.
Esta tesis presenta una auditoría energética de una cabina de pintura. El objetivo es reducir el consumo de energía de la cabina de imprimación del proceso de pintura de la fábrica de Toyota en Francia, siguiendo la metodología de una auditoría energética.
La imprimación es uno de los pasos de la aplicación de pintura en los coches. Sirve para aumentar la durabilidad del vehículo. En la industria automovilística, este proceso consume alrededor de la mitad de la energía necesaria para su producción. Por ello, existe un gran potencial para introducir medidas de ahorro.
En primer lugar, se realiza un mapeo energético para entender cómo fluye la energía dentro del proceso. En segundo lugar, la auditoría se centra en el estudio de arranque y parada de los equipos de la cabina de pintura. Finalmente, combinando ambos análisis se sugieren posibles medidas y se analizan tanto a nivel energético como de emisiones de CO2.
El estudio establece que una gran cantidad de energía podría ser ahorrada cambiando tan solo la forma de operación de los equipos. Asimismo, se puede conseguir un mayor ahorro con el cambio a una tecnología más eficiente. Más en detalle, de los 8908 MWh que se consumen al año en la cabina de imprimación, el introducir las medidas propuestas, supondría un ahorro de 1641 MWh. Además, se podrían reducir las emisiones en 191 toneladas de CO2.
Energy is a key for economic growth and prosperity. However, the expected demand growth has made its consumption reduction a priority. In this thesis an Energy Audit of a Primer Booth is presented. It will aim to reduce the energy consumption of the primer booth used in the painting process of the Toyota’s plant in France by applying the energy audit methodology. Primer is one of the steps that involves the paint application on vehicles. Moreover, it gives durability to the car body. In the car manufacturing industry painting is claimed to consume around half of the energy needed for the production. Therefore, if energy saving measures are implemented, energy consumption could decrease. First, an energy mapping is carried out to understand the energy usage and breakdown of the process. Secondly, the operation pattern of the equipment is studied. Finally, combining the two previous analysis a list of potential improvements is proposed and analyzed both regarding energy and CO2 emissions. The study shows that by changing the operational behavior of the equipment a large amount of energy could be saved. Further savings could be also achieved by changing the current technology into a more efficient one. More in detail, out of 8908 MWh per year that the primer booth consumes, 1641 MWh could be saved. Additionally, 191 tons of CO2 could be reduced from current emissions.
