“…One of the tasks that are solved by experimental studies of thermal comfort regulation in the passenger compartment is to determine the actual values of the initial and boundary conditions of mathematical models for their further computer-based numerical solution, taking into account the subjective perception of microclimate parameters by humans, as is proven in paper [21]. Researches [20,22,23,24,34] involve the study of functioning thermoregulation mechanisms of the human body and its reaction to the heating and cooling microclimate, such as the model of thermoregulation developed in The University of California, Berkeley (UCB) and the multisegmental (MS) Pierce model, as well as in the compartment of the wheeled vehicle, according to papers [25,26]. The purpose of these studies is to improve methodologies for objective evaluation of subjective perceptions caused by the effect of working microclimate parameters.…”

This paper presents the results of theoretical computer-aided research of the microclimate parameters in the vehicle passenger compartment during operation of one of the widely used schemes of heating system in the passenger compartment, taking into account the breathing of passengers. Theoretical researches of the heating system operation in the passenger compartment taking into account passenger breathing have been conducted. Distribution of microclimate parameters in the passenger compartment cross-section, in the case of using a heating system having one compartment heater, with and without taking into account the breathing of passengers, has been obtained. The assessment of the effect of passengers' breathing on the microclimate parameters in the passenger compartment has been carried out. The outcomes of this research may be of interest to specialists involved in the design and ergonomics of wheeled vehicles and labor protection.

“…Air-conditioning (AC) system performance is one of the major concerns related to automobile energy consumption [1]. To date, most automobile manufacturers prioritize customer comfort by using windpipe allocation and server motor control to develop automatic temperature controllers [2][3][4]. The aforementioned technique used the temperature differences at each air inlet to conduct AC adjustment.…”

With the goal of increasing energy efficiency and passenger comfort in an automobile cabin, we developed a regional air-conditioning design to control cold air in specific regions, and an air management strategy that can keep air circulation when the car engine cuts out. According to computational simulations, an air velocity of 2 m/s was adopted, which could form an independent flow field space in the cabin with a temperature gap of 7 °C according to the user’s needs. The designed regional air-conditioning and circulation system could create independent flow field spaces with temperature differences. Inlet air volume demand was also reduced by 60% and blower power by 53 W. In addition, the cabin ventilation system led air exchange rate reached 89% per hour. In 20 min of exposure under sun, the system could lower the cabin temperature by 12.3 °C.

“…However, talking about vehicles, there are certain limits which, if they are too high, they may cause a sense of stress. Danca et al stated that thermal comfort leads to a safer trip, because it reduces the driver's stress [13]. Research by Singh et al showed that a uniform temperature inside the cabin of a parked car can be maintained using a particular vent angle, unfortunately not every car has a dynamic air vent [14].…”

Under a condition of sunlight exposure, the temperature of a parked car's cabin will increase gradually. Compared to the ambient temperature, the inside and outside temperature will be different, which will be favourable for thermoelectric generators. This study investigated the temperature distribution pattern of a car parked in the direct sun using real and model cars. Performing different scenarios, we found that the car model equipped with a fan and a dimmer was the suitable approach to the real car model. Compared to the ambient temperature, results for both the real car and the model car indicated that heat rose drastically inside the car cabin. The calculation using the thermoelectric generator eTEG HV37 considerably could generate up to 6.9 mW per module. Therefore, by having a thermoelectric generator installed on an area of 1 m 2 of the car roof, 280 W power could be generated.
