Análisis de la correlación de la concentración de CO y CO2 en el habitáculo de vehículos tipo SUV con la temperatura y humedad relativa en el interior de los vehículos

Abstract

This research work aimed to establish the correlation between the concentrations of carbon monoxide and carbon dioxide in the passenger compaftment of four SUV-type vehicles (Kia Sportage) with temperature and relative humidity through the use of the calibrated measurement eqr"ripment IAQ Testo 440 with two measurement probes, where probe I delivers CO values while probing 2 registers CO2, temperature, relative humidity, and atmospheric pressure. The measurements were made in the driver and passenger area considering a separation partition between these areas, in three diflerent modes of operation of the air conditioning system, with the vehicle parked and its revolutions at idle. The data collection was based on the Russian interstate regulation GOST 33554-2A15. In the results, the behavior of the variables and the corelatio¡l between them were determined, resolving that, during the three modes of ventilation and in the two study areas, there was an inverse linear correlation with an average percentage of 460A between carbon monoxide and relative liurnidity, an inverse linear correlation with a substantial percentage determination equivalenl to 64Yo between carbon dioxide and relative humidify, a direct linear correlation with a reasonable percentage determination equal to 580/o between carbon monoxide and close humiclity temperature, and a straightforward linear correlation with a substantial percentage of determination equivalent to 77Yo between carbon dioxide and the temperature in the passenger compaftme¡rt of the vehicles. It w-as concluded that as the concentrations of CO and CO2 increase, the temperature in the passenger compartment increases, and the relative hr"rmidity decreases. It is recomrnended to take precautions when turning on tlie air conditioning system since misuse can cause serious health problems for the occupants.
