Today’s customers often require the vehicle manufacturer to document passenger compartment heating for specific test conditions. Without correct selection and sizing of the HVAC system for the passenger compartment, thermal comfort cannot be ensured. One of the aims that the manufacturers of modern vehicles have in mind is the development of new and optimization of the existing systems for achieving and maintaining thermal comfort in the passenger area. The selection of system components to achieve the required thermal comfort in the passenger compartment is the first step. The second step consists on the optimization of the selected thermal comfort control concept of the passenger compartment under various environmental conditions. For the computerized evaluation of thermal comfort at selected standing place, the 4 following measurement variables are used: air speed, humidity, air temperature and the temperature of the black ball. In addition to the prediction of percentage of unsatisfied persons during the heat up phase of the vehicle passenger compartment, the special thermal conditions in the vehicle are pointed out. Within the scope of the work the thermal comfort of the inhomogeneous is compared with the homogeneous environment. Using the operational and the equivalent temperature according to SAE J2234 the homogeneous environments are determined. The following external conditions are constant; incident-flow velocity of the vehicle, air temperature and humidity. The aim of the paper is to indicate a complexity of determining the thermal comfort conditions in passenger vehicles.

Introduction. A distinctive feature of working conditions in the Arctic territories is the long period of exposure to low temperatures. Passenger transportation by road is becoming one of the key aspects of ensuring the continuity of the production process. The task of delivering workers to the place of work, moving them between work zones during a work shift is solved by using wheeled vehicles of various categories. One of the most widespread types of wheeled vehicles used to transport workers is the M3 category wheeled vehicles with a capacity of no more than 22 passengers. Ensuring the thermal comfort of vehicle passengers seems to be relevant, since ensuring biophysical compatibility minimizes the risks of cold injury by workers and maintains a high level of performance.Materials and methods. The results of the analysis of the Russian and foreign studies in the direction of ensuring thermal comfort and ensuring biophysical compatibility in confined spaces are presented. The results of computer modelling of the dynamics of microclimate parameters in the passenger cabin of a wheeled vehicle of M3 category with a capacity of no more than 22 passengers are presented.Results. The paper presents the results of theoretical studies, microclimate parameters in the passenger compartment of vehicles, taking into account the breathing of passengers and changes in the gas composition of exhaled air. Theoretical studies of the operation of the heating system of the passenger compartment were carried out, taking into account the refined breathing model of passengers. Distributions of microclimate parameters in the section of the passengercompartment were obtained when using a heating system with one heater; the impact of passengers’ breathing on the parameters of the microclimate in the passenger compartment was assessed.Discussion and conclusion. Based on the numerical solution of the system of heat transfer equations, directions for further research and recommendations are formulated to ensure thermal comfort in the passenger compartment of a wheeled vehicle at low temperatures. The materials of the work may be of interest to specialists involved in the design and ergonomics of wheeled vehicles, labor protection.
