“…The scheme of the system considered is sketched in Figure 1. The dimensions and physical characteristics of the system correspond to studied solar chimney values and with experimental data published by Lahimer et al, [4]. The solar air collector system consists of an enclosure, a single glass, an absorber made of black metallic, and insulations [6,18,25,27,28].…”

“…Till now, there has been increasing interest in re-employing solar chimney principles for different applications in different fields, for example, integrating solar chimney power systems with seawater desalination to produce electricity and freshwater [16]. Recently, Lahimer et al, [4] introduced the solar chimney concept as a promising passive approach for cabin soak temperature reduction.…”

“…Besides, its application is unsuitable for window-tinted cars because tints will decrease solar panels' solar energy absorption [2]. However, passive cooling from an approach that uses solar energy to induce natural ventilation for enhancing cabin thermal comfort and fuel economy under hot soaking conditions can be obtained from a solar chimney which demonstrated promising results in reducing the peak cabin soak temperature (20.5°C), as reported in Lahimer et al, [4].…”

Exposure to direct sunlight raises interior temperatures in vehicle cabins, risking heat-related illnesses. Solar passive techniques mitigate this issue, especially during hot parking conditions. However, a comprehensive mathematical model encompassing both solar chimney and vehicle cabin is lacking. This study develops a novel mathematical model to predict temperature distribution and airflow rate, enhancing system performance evaluation. The system comprises a solar air collector with an adjustable arm mounted on the vehicle's roof. The model was validated theoretically and experimentally. The experimental work is conducted with the physical model with an air gap of 0.1 m, 0.77 m width, and a 1.12 m collector length under outdoor conditions. Results indicated a gradual increase in temperatures of the glass cover, air in the collector channel, absorber, and mass airflow rate with solar radiation intensity, significantly influencing system performance. The high value of R2 and the consistency of the model's results with theoretical and experimental outcomes justified the validity and accuracy of the proposed model, exhibiting a deviation percentage of less than 10%. The developed model can be utilized to study influential parameters for optimizing the proposed strategy's performance and components, yielding comparable results to experimental data. Additionally, it provides researchers and car makers with a broader perspective and a range of options for further improvement in weight, size, cost, and aerodynamic of the vehicle.

The consumption of energy for cooling is an important issue, especially in subtropical climates where there are high temperatures and dry weather in the summer; this climate forces homeowners to use mechanical-electric cooling and ventilation. The main advantage of passive cooling is to minimize energy demands which are required to achieve thermal comfort in buildings, especially with climates exhibiting high ambient temperatures. This paper presents a detailed literature review and concept breakdown for passive cooling and ventilation in building by offering the fundamental principles of the techniques of passive cooling and ventilation. Moreover, the status of passive cooling developments along with state-of-the-art research is critically reviewed in this paper. Furthermore, the article focuses on Buoyancy air-driven ventilation. Solar control techniques are explained and classified along with techniques for heat modification and dissipation. This paper offers insight into the design considerations of different passive ventilation systems and presents recommendations for future work to achieve cost-efficient, comfortable living. Moreover, novel systems are reviewed and discussed to better understand the role of Phase Change Material (PCM) in passive cooling systems.
