Investigation of air exchange at the workplace of a bus driver

The focus on thermal comfort of the driver and passengers is important not only for reasons of convenience, but also for safety reasons. This article examines the microclimate at the driver’s workplace, which is formed on the basis of heat exchange between the exterior and interior of the cabin, as well as in the cabin itself. The influence of various factors and operating conditions on the microclimate in the bus interior is analysed. Attention is focused on local thermal comfort devices, since thermal comfort systems now work in an integrated manner, paying special attention to local thermal comfort. A ventilation system was modelled, which works to take fresh air into the cabin with forced removal to the outside. The air exchange at the workplace of a city bus driver with injection fans mounted in the roof of the bus, one of which works to draw fresh air into the cabin and the other to force it out, at air blowing speeds for four modes from 0.1 to 0.5 m/s, was modelled. The organisation of air exchange at the driver’s workplace is proposed, which can be used in the design of thermal comfort for new models of vehicles, especially large-sized ones, such as buses
