Diseño y construcción de un porta paquetes de ducto circular para mejorar la distribución de aire acondicionado en buses interprovinciales, en la empresa Miviltech Soluciones Industriales S.A”

Abstract

The present project details the process of design and construction of interior trim of circular duct to improve the distribution of air conditioning in interprovincial buses, in the company Miviltech Soluciones Industriales SA, using as base the resolution N° 14429 of the RTE-043 INEN of the ministry of industry and productivity undersecretary of quality: first edition, "That in accordance with the provisions of article 52 of the constitution of the republic of Ecuador. The fundamental purpose is to develop design the bus interior trim that improves the distribution of air conditioning inside the interior trim duct providing greater comfort to the user, which is in accordance with the requirements of the aforementioned standard. In the initial stage, a diagnosis of air conditioning distribution was made in the interior trim, based on the quantitative analysis of the flow rate and air conditioning distribution speed, to determine the dimensioning of the duct as well as its shape, having as main research source scientific articles related to the area of mechanical design, air conditioning and fluid mechanics. All the design procedures were generated, then the new model was designed and software simulations were carried out in which it was possible to adjust the appropriate parameters for the distribution of the air inside the duct, later the assembly of the prototype was made with wood, sheet metal and fiberglass using the operations of laser cutting and plasma cutting, and with the help of CNC machining machinery in tables of 1000 x 70 x 50 mm of wooden planks thus creating a matrix to remove parts in fiberglass and assemble the interior trim.
