Evaluación de la ventilación en aulas y otros espacios físicos de la Universidad Politécnica Salesiana "Campus Sur" utilizando como referencia la concentración interior de CO2

Abstract

The present experimental work focuses its development on evaluating the ventilation of classrooms and physical spaces of the Universidad Politécnica Salesiana "Campus Sur". As is known by all, educational institutions currently face the determination of capacity that allows maintaining adequate ventilation in places that require attendance. When air tightness occurs, there is the possibility of adverse health effects, thermal discomfort, hypoxia, respiratory conditions, including the spread of COVID-19. Taking into account the risks mentioned to which people who need to occupy these working spaces are exposed, there must be a ventilation system that can be natural or mechanical, with which you can regulate everything from temperature to speed. air recirculation. In the case of the Universidad Politécnica Salesiana "Campus Sur", there is a natural ventilation system, which is obtained from windows, doors and grilles. This work aims to determine if the places of study: classrooms, offices, laboratories, have optimal and suitable ventilation to return to face-to-face classes, this was done through measurements of internal concentration of CO2 that allowed calculating the renewal of air in each site. Subsequently, possible solutions are compared and proposed to reach the objective of correct air renewal.
