Análisis del impacto ambiental en el uso del aire acondicionado en un vehículo bajo el ciclo de conducción de Riobamba

Abstract

The objective of this research project was to analyze the environmental impact f the use of air conditioning in two vehicles fulfilling the Riobamba driving cycle. The initial study included the review of real data in previous investigations that allowed to know in detail the characteristics of the air conditioning system, since the activation of the air conditioning generates a greater variation of polluting emissions and something similar occurs with fuel consumption; in addition, direct observation was used for data collection. Subsequently, experimental research and field work established the dependent variable, the air conditioning system; and, the independent variables, speed, time, revolutions per minute, emissions of CO2, CO, HC, NOx, establishing two vehicles as a sample of the study, KIA PICANTO and AUDI Q5. The quantitative approach applied in the measurement of independent variables through specialized equipment, as well as in data analysis. A database was made jointly from the Maha 6.3 gas analyzer and the ELM 327 on board device second by second, fulfilling the driving cycle with their respective protocols for each test. The two databases were related to Minitab and Tableau, obtaining a Pearson correlation to its displacement is adjusted to the speed of the driving cycle provided for the investigation. Determining that in the two study analyzes represented by different displacements 1200cc – 2000cc there are higher pollution emissions and fuel consumption with the activation of the air conditioning. Users of motor vehicles are recommended to avoid excessive use of air conditioning and thus reduce the emission of polluting gases into the environment.
