The present research paper investigates the designof a Solar-Powered Cold Box.Because of its low cost and zero pollution, passive evaporative cooling has great potential as an alternative to conventional air-conditioning in rural areas.Solar chimney is a wonderful passive
ventilation system as it relies on the sun energywhich is a natural driving force.This paper presents a new modeling of an evaporative cooling system.The Solar-Powered Cold Box isoperated entirely without electricity,utilizing simple physical phenomenon like evaporative
cooling, thermal insulation, and solar chimney–induced natural convection.In this paper, the design and operating principles are discussed in detail. A mathematical model is simplified by the
assumption of Heat transfer (conduction + convection), Pressure difference, Latent heat of Evaporation, Thermal expansion of air and Pressure gradient.The study shows that non-electrical
solar cold boxes provide a low-cost, eco-friendly, sustainable, and maintenance-free solution for decentralized cold storage.The study describes a theoretical configuration andproposes experimental mode
