Estudio de la incidencia de los niveles de emisiones de gases CO y CO2 y temperatura, del sistema de climatización automotriz al interior de un bus interprovincial a diferentes condiciones ambientales y de funcionamiento

Abstract

The present curricular integration work proposes to analyze the levels of CO and CO2 gas emissions in the passenger compartment of an interprovincial bus, considering environmental and functional conditions, to obtain values that are analyzed, allowing to know the comfort conditions of the passenger, considering an ideal temperature of 22°C. On the selected route, the study was carried out during the bus route, both in the central and peripheral urban sectors, where the influx of users is notable throughout the day. The field measurements were carried out (August 5 to August 10) inside the passenger compartment of an interprovincial bus, considering operating variables of the automotive air conditioning system, such as condition, OFF, air recirculation and air renewal. Data collection was carried out in the front, middle and rear sections of the passenger compartment. An IAQ TESTO 440 gas analyzer was used through the CO2 probes and the CO probe, it Will be located at a height of 1.1 m from the floor, which was considered as the average respiratory level of the passenger, generating the data in lapses of 10 minutes. Once the analysis was carried out, the data was tabulated and the concentration levels of emissions produced by the users' exhalation were determined. Finally, it was possible to know the concentration percentages of the gas emissions produced by the users, in the different locations of the passenger compartment. It is recommended that for future research, a study be carried out with data collected from a full day of travel.
