Vehicles parked under blazing sun increases the cabin temperature to a broiling point as greenhouse effect comes into play. Similar is found in winter season when vehicle is parked in open, cabin temperature falls drastically. This extreme rise and fall in the vehicle cabin temperature, results in more fossil fuel consumption to power air-conditioner for high loads, which eventually leads to increase in generation of harmful gases. Additionally, the drastic condition inside vehicle cabin makes it profusely miserable for human comfort. Thus, relevant renewable energy powered cooling/heating system is required for the vehicle cabin when parked in open areas. Therefore, in this study initially, a 3D heat and mass transfer model is developed for evaluating temperature variations in vehicle cabin for summer and winter seasons. Then, a solar powered thermoelectric cooling-heating system is proposed to resolve the extreme rise and fall of vehicle cabin temperature without running the engine or using any power from the primary source. And, the thermal performance of the proposed system is evaluated and assessed in the numerical study. The proposed system was able to reduce the average temperature of the cabin space by 17 °C in summer season and the average temperature rise of the cabin space is found by 15 °C in winter season. The solar simulator for the vehicle rooftop solar panel investigated annual averages of normalized energy per day and loss in solar energy collection due to variation in tilt angle, which was around 20%. Thus, the present study demonstrates the feasibility of proposed novel solar assisted thermoelectric cooling/heating system in both summer and winter seasons. Hence, study demonstrates that the thermoelectric technology with solar assistance is effective and viable for cooling and heating of vehicle cabin during parking.

随着温室效应的发挥，停在烈日下的车辆会将车内温度升高到炙手可热的程度。冬季车辆露天停放时，车内温度急剧下降。车厢温度的这种极端上升和下降，导致更多的化石燃料消耗来为高负荷的空调供电，最终导致有害气体的产生增加。此外，车厢内的恶劣条件使人类的舒适度非常悲惨。因此，当车辆停放在露天区域时，需要相关的可再生能源驱动的冷却/加热系统。因此，在这项研究中，最初开发了一个 3D 传热和传质模型，用于评估夏季和冬季车厢内的温度变化。然后，提出了一种太阳能热电冷暖系统，以解决车内温度急剧上升和下降的问题，而无需启动发动机或使用任何主要来源的动力。并且，在数值研究中评估和评估了所提出系统的热性能。所提出的系统能够在夏季将客舱空间的平均温度降低 17°C，在冬季发现客舱空间的平均温度升高 15°C。用于车辆屋顶太阳能电池板的太阳能模拟器调查了每天标准化能量的年平均值以及由于倾斜角变化而导致的太阳能收集损失，约为 20%。因此，本研究证明了所提议的新型太阳能辅助热电制冷/供暖系统在夏季和冬季的可行性。因此，研究表明，太阳能辅助的热电技术对于停车期间的车厢冷却和加热是有效和可行的。
