Abstract
The global pandemic due to the COVID-19 disease has led to the study of school classrooms as possible vectors of contagion. The CO2 has been established with an easily captured indicator to determine the adequate ventilation of these spaces. However, continuous ventilation can cause a lack of comfort in students and therefore be detrimental to their cognitive development. Therefore, it is necessary to study an optimal way to ventilate and the objective of this study is to evaluate the CO2 of a school classroom to optimize natural ventilation, minimizing the loss of comfort and thus reducing the risk factor for COVID-19. CO2 and air flow measurements were carried out in three study days in a secondary school in Madrid in which tests were carried out on the closing and opening of doors and windows to determine the opening time necessary to reach an optimal level of CO2.
Resumen
La pandemia mundial por la enfermedad del COVID-19 ha llevado a estudiar las aulas escolares como posibles vectores de contagio. Se ha establecido el CO2 con un indicador de fácil captura para determinar la adecuada ventilación de estos espacios. Sin embargo, la ventilación continua puede ocasionar falta de confort en los estudiantes y por lo tanto ir en detrimento de su desarrollo cognitivo. Por lo tanto, es necesario estudiar una forma óptima de ventilar y el objetivo del presente estudio es evaluar el CO2 de un aula escolar en aras de optimizar la ventilación natural minimizando la pérdida de confort y así disminuir el factor de riesgo ante el COVID-19. Se realizaron mediciones de CO2 y caudal del aire en tres jornadas de estudio en un colegio de secundaria en Madrid en el cual se realizaron pruebas de cierre y apertura de puertas y ventanas para determinar el tiempo de apertura necesario para llegar a un nivel óptimo de CO2.
