Evaluación de la concentración de dióxido de carbono (CO2) en espacios intramurales en relación con las medidas de bioseguridad de la Universidad Santo Tomás, Villavicencio

Abstract

The transmission of respiratory diseases transmitted through the airway is a topic on the rise in research due to the recent pandemic caused by the SARS-CoV-2 virus, consequently, its relationship with the dispersion capacity of suspended particles containing respiratory diseases in closed spaces with natural, mechanical or no ventilation at all (Crespi & Ordóñez, 2022). Based on the above, the concentration of carbon dioxide CO2 in intramural spaces of the Universidad Santo Tomás Villavicencio, Aguas Claras, in the classrooms of both buildings, was evaluated. The method to be used was divided into three phases, first, data collection together with a non-dispersive infrared sensor and the calculation provided by (Rodriguez et al L., 2021), the calculation of the mean absolute error to check the concentrations of CO2 obtained with a percentage error of 4.84%; second, the execution of an ANOVA analysis of variance that reflects the direct relationship between the smallest opening area with respect to the CO2 concentration with an F= 3.884 while the temperature had a direct relationship with the capacity with an F= 3.180, being the rate of reaeration and the concentration of CO2 the most sensitive variables; discussing the veracity of the results found by (Gónzalez, 2022), it is recommended that the research be directed to an analysis of the urban wind canyon as an external measure and the understanding of these phenomena with the help of software such as CDF and DesignBuilder.
