    Diseño y construcción de un banco de pruebas de calentamiento de aire en ductos para el Laboratorio de Energía de la Carrera de Ingeniería Mecánica

    In this technical project, information has been collected on the types of heat exchangers, types of fans, measurement systems, construction materials, heat and temperature analysis, as well as structural stresses and deformations. Subsequently, the support structure, the air ducts and a heat generating coil were designed and built, with the use of analysis methods exposed in specialized books and others such as the selection of alternatives by weighted criteria, specialized software in static analysis and simulation of fluids. Then the measurement and control equipment was assembled with these to finally put into operation the test bench for heating air in ducts by means of steam The air heating system consists of a shell and tube heat exchanger. The steam will be generated by a 2 horsepower boiler steam boiler. To carry out the performance tests, the air temperatures at the outlet of the exchanger have been measured, controlling by means of a regulation damper the amount of mass of air that enters it, from 100 percent = 0.0669 kilograms per second, 75 percent = 0.0502 kilograms per second and 50 percent = 0.0334 kilograms per second, thus taking the temperature variations through two K-type thermocouples placed in the sections of the ducts. And under an analysis of results it was determined that when the incoming air mass is reduced, the air temperature at the outlet of the exchanger increases from 43.01 degrees Celsius, 50.31 degrees Celsius and 65.36 degrees Celsius respectively at the air mass inlet.
