Diseño de un sistema de aire acondicionado para el bloque A de la Universidad Antonio Nariño – sede Buga, con base en la norma ANSI/ASHRAE 62.1

Abstract

The human activities are governed by external agents, for example, a thermal sensation of comfort is determined in most cases by the activities that are carried out and therefore it is important for the perception of well-being and performance of people's performance. The purpose of this degree work is to carry out the design of an air conditioning system for block A at the Antonio Nariño University, Buga headquarters, which was based on the ASHRAE standard, chapter 62.1 ¨Ventilation for Adequate Air Quality Inside. The zoning of each built area was carried out to calculate the thermal load, which includes offices, classrooms, laboratories, auditorium, systems room, etc., achieving a total area of 1830.8 m2 of calculation for the five floors considered in this project, with a cooling load of 120.57 TR in the entire system. Taking the calculated thermal loads as a principle, a review of the psychometric chart was made in each of the equipment to specify the required suitability and establish the adequate dimensions of the ducts according to the CFM (cubic feet per minute) required for each area, opting for a water-cooled condensation system. In the last stage of this project, the architectural plans are made with the layout of the supply and return ducts, this in order to determine the layout of the optimal trajectory that allows adequate operation at speeds and decibels and thus guarantee indoor air quality, as well as equipment selection
