Spanish Abstract: Este trabajo tiene como objetivo disenar una camara de aire con las dimensiones minimas y las caracteristicas hidraulicas adecuadas para evitar el riesgo de rotura por sobrepresion o el colapso por depresion en lineas de conduccion. Para obtenerlo se implemento un algoritmo genetico, el cual es una tecnica de busqueda y optimizacion, basada en el proceso evolutivo de los seres vivos. El algoritmo evalua, selecciona y mejora las posibles soluciones, la mejora esta basada en la seleccion de la poblacion inicial y en el numero de simulaciones generadas. En un trabajo anterior se optimizo solamente el volumen de la camara sin tener en cuenta las perdidas de entrada y salida en la interconexion entre la linea de conduccion y la camara de aire. Las “soluciones” elegidas a traves del proceso del algoritmo son evaluadas en TRANS (un software creado por el Instituto de Ingenieria de la Universidad Nacional Autonoma de Mexico, el cual utiliza el metodo de las caracteristicas para determinar el valor de las envolventes de presion maximas y minimas que generan los individuos) encontrando convergencia conforme aumenta el numero de generaciones. Esto demuestra la efectividad del uso de algoritmos geneticos para el dimensionamiento de las camaras de aire, asegurando la proteccion de la linea de conduccion, evitando asi sobredimensionamiento y sobrecostos para su fabricacion. English Abstract: The objective of this work is to design an air chamber with minimum dimensions and adequate hydraulic characteristics to avoid the risk of overpressure rupture or collapse by depression in driving lines. To obtain this, a genetic algorithm was implemented, which is a search and optimization technique, based on the evolutionary process of living beings. The algorithm evaluates, selects and improves the possible solutions, the improvement is based on the selection of the initial population and the number of simulations generated. In an earlier work, only the volume of the chamber was optimized without taking into account the inlet and outlet losses in the interconnection between the conduction line and the air chamber. The "solutions" chosen through the algorithm process are evaluated in TRANS (a software created by the Institute of Engineering of the National Autonomous University of Mexico, which uses the method of the characteristics to determine the value of the maximum pressure envelope and minimums that individuals generate) finding convergence as the number of generations increases. This demonstrates the effectiveness of the use of genetic algorithms for the dimensioning of the air chambers, ensuring the protection of the conduction line, thus avoiding oversizing and cost overruns for its manufacture
