Evaluation of the thermal comfort for its occupants inside a vehicle during summer

Experimental investigation of thermal vehicular environment during the summer season

“…Some photographs of the experimental set-ups for each of the experimental method are shown in figure 6. The thermal manikin and the Comfort Sense system were placed on the driver place for two measurements sets cases (Danca et al 2019).…”

Theoretical studies of the heating system in the vehicle compartment during passenger transportation taking into account breathing under conditions of low temperatures

“…It should be noted that studies of microclimate in confi ned areas are developed in several directions. Experimental studies with the use of a thermal passenger manikin with the increase of its adequacy presented in papers [3,6,13,14,17] as well as experimental studies of microclimate parameters of the existing systems of thermal comfort provision in passenger compartments of cars [16,17] and buses [15], including the use of a fullsize climatic chamber described in paper [25] have been conducted. The results of experimental studies of microclimate parameters and atmospheric composition of the passenger compartment for different models of wheeled vehicles in hot climate conditions are presented in papers [10,18].…”

“…Thus, for the moment researches of the effect of practically all elements of the wheeled vehicle technical system on the achievement of thermal comfort in the compartment have been conducted, as can be seen from papers [31,32,46]. The assessment of arising subjective sensations of passengers under certain microclimatic conditions is presented in papers [7,17,26]. Different schemes of microclimate regulation and thermal comfort provision for different types of wheeled vehicles have been studied in papers [9,20,29].…”

“…Assessment of changes in microclimate parameters in time and various driving conditions of a wheeled vehicle has been performed in papers [11,15,16,19]. It has been established that the parameters of microclimate in the compartment during movement are not constant, as well as subjective sensations of thermal comfort are different when the vehicle is moving and when it is motionless, as demonstrated in papers [11,16,17]. However, almost all papers consider the thermal comfort provision in conditions of heating microclimate which can be found in papers [9,10,12,15,17,18,19,25,27,29,31,33]; at the same time passengers represent passive receptors in the context of the environment, as is proven in paper [43].…”

Therefore, assessment of heating system effi ciency under conditions of cooling microclimate in the cold period of the year and determination of actual values of microclimate parameters in the compartment for wheeled vehicles of M3 category with the seating capacity not exceeding 22 passengers, taking into account the external respiration of a person as a constituent element in providing thermal comfort, is one of the further research trends in regulation of microclimate of the passenger compartment of the wheeled vehicle.…”
