Paperback. Condición: new. Paperback. This project presents the design and fabrication of a Portable Solar Air Cooler that operates using renewable solar energy. The increasing demand for cooling systems, especially in remote and rural regions, creates a need for low-cost, energy-efficient, and eco-friendly alternatives to conventional electrical coolers. This project integrates a solar photovoltaic panel, 12V DC fan, battery backup, water pump, and cooling pads to create a compact, portable, and sustainable cooling device.The fabricated model uses a 20W solar panel for powering the cooler during daylight, along with a 12V 7Ah battery to ensure continuous operation during cloudy conditions. The system demonstrates effective airflow, reduced electricity consumption, and portability. This portable solar air cooler is especially useful for outdoor workers, street vendors, small shops, villages, and areas without reliable electricity.It demonstrates that such a system can effectively provide comfortable airflow while maintaining low power consumption and promoting clean energy usage. The system reduces dependency on grid electricity, lowers operating costs, and is especially useful in remote or off-grid locations. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…

Paperback. Condición: new. Paperback. Ce projet presente la conception et la fabrication d'un refroidisseur d'air solaire portable fonctionnant a l'energie solaire renouvelable. La demande croissante en systemes de refroidissement, en particulier dans les regions isolees et rurales, rend necessaire le developpement d'alternatives peu couteuses, economes en energie et respectueuses de l'environnement aux climatiseurs electriques classiques. Ce projet integre un panneau solaire photovoltaique, un ventilateur 12 V CC, une batterie de secours, une pompe a eau et des tampons de refroidissement afin de creer un dispositif de refroidissement compact, portable et durable.Le modele fabrique utilise un panneau solaire de 20 W pour alimenter le refroidisseur pendant la journee, ainsi qu'une batterie de 12 V 7 Ah pour assurer un fonctionnement continu par temps nuageux. Le systeme offre un debit d'air efficace, une consommation electrique reduite et une grande portabilite. Ce refroidisseur d'air solaire portable est particulierement utile pour les travailleurs en exterieur, les marchands ambulants, les petits commerces, les villages et les zones depourvues d'un reseau electrique fiable. Il demontre qu'un tel systeme peut fournir efficacement un flux d'air agreable tout en maintenant une faible consommation d'energie et en favorisant l'utilisation d'energies propres. Le systeme reduit la dependance au reseau electrique, diminue les couts d'exploitation et s'avere particulierement utile dans les zones isolees ou hors reseau. This item is printed on demand.

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The growing demand for clean and sustainable transportation has accelerated the development of Solar Electric Vehicles (SEVs). This project focuses on the design and fabrication of a solar-powered electric vehicle that reduces dependence on conventional charging and minimizes carbon emissions. The system integrates photovoltaic (PV) solar panels, a charge controller, and a rechargeable battery pack to power a high-efficiency 750W Brushless DC (BLDC) motor. A 48V, 20Ah lithium-ion battery serves as the primary energy storage unit, ensuring reliable and efficient vehicle operation. Testing under various load conditions demonstrated stable performance, good acceleration, and extended range. The study highlights the importance of optimized battery integration and renewable energy utilization in improving SEV reliability and practicality. Overall, the project demonstrates the feasibility of combining solar energy and advanced battery systems to create a sustainable, cost-effective, and environmentally friendly transportation solution, contributing to the advancement of clean and self-sustaining mobility systems.…
