Dimensionamiento de ductos de ventilación y cálculo de cargas térmicas en edificaciones estándar mediante el desarrollo de un software

Abstract

In this project two programs are prepared and developed, one in the field of mechanical ventilation and the other in air conditioning. Both uses the programming package Visual Studio 2010. The software for mechanical ventilation is developed as an attached library of AutoCAD 2012, which allows the user to design rectangular and round section ducts by entering parameters for material, flow, pressure drop, length, air density of interest, etc. On the other hand, the cooling loads software allows the user to provide data according to the source (windows, walls, ceilings, internal surfaces, occupants, air exchange, lights or electrical appliances), it can display the total cooling load as a set of areas or plants in one-hour steps. Moreover, the cooling loads software allows the user to change the geographical and design conditions for a complete recalculation of loads. It has an option to show the optimum orientation of the building which also reduce the cooling load and as a consequence the cost of air conditioning equipment. Each software developed in this project follow ASHRAE and SMACNA’s methods with its respective validation, description and user manual to facilitate the use and understanding.
