Description
Quality of air in cabin of transportation vehicle is becoming even more important nowadays with increase in globalization and transportation . Vehicular combustion is the most substantial source of pollution in densely populated urban areas. It is constituted of gaseous pollutants and ultrafine particulate matter (UFP)) descibed as PM values. Intensive industrial development an fossil energy utilization in metropolitan areas of developing contries resulted in increase of trade and daily exposure to traffic-related air pollutants (TRAPs) of heavy-duty vehicle drivers. Primary sources of UFPs in the urban environment near road sites are caused by vehicles, and ther concentrations of pollutants is three times higher during peak traffic timein, aslo affecting in-cabin exposure od drivers. High concnetrations of CO2 and NOx accumulate onto respiratory tract and from there eneter blood stream reducing decision-making performance. Therefore, it is important to reduce both gaseous and particulate pollutants in th ecabins through effective ventilation system design.
The aim of this study is to highlight necessity of removal of pollutants that enter cabins of heavy-duty vehicles during the driving, inhalated by drivers during both working hours and rest time, directly from air or from cabin surfaces. Even the most effective filters are prone to aging due to particles accumulation on their surface, which causes reduction of pressure drop avross filter surface and reduces its efectivness. Influence of filter aging can have important implications when aiming to improve conditions for drivers’ health and road safety.
In this research experimental results from several types of filter design are accompanied with modelling approach revealing the importance of both filter material and filter design on air filtration. Good correlation between experimental and mathematical results from field measurements conducted in a highly polluted city.
