Résumé / Abstract
The air conditioning of vehicle cabins is now standard equipment for vehicles. Increasing the consumption of fuel, the air conditioning also raises difficulties and costs with its integration in the electric and hybrid vehicles, because of the continuous or punctual absence of hot source as is the internal combustion engine. In this paper, we study the interest of the techniques of adiabatic cooling to cooling down a cabin of an agricultural machine. Recordings of the activity of a tractor in real situation are used for studying the temperatures inside the cabin along a typical working day. From these observations, we adapted a model to estimate the thermal exchanges of the cabin with the environment. The solar incomes are estimated under various countries in France and the ventilation rate is taken into account. We substitute then the air conditioning by a system that mists water droplets on the air admission for the cabin. The efficiency of this cooling system depends mainly of the atmospheric conditions and we establish, for various weather situations, the cooling capacity of this process. So the temperatures inside the cabin are assessed, as well as the water consumption. These results add to efficiency assessment about adiabatic cooling systems for industrial vehicles.
