Description
Eco-friendly food storage uses evaporative cooling, ice packs, brine solutions, and solar-powered thermoelectric coolers to keep produce below 4 °C without conventional refrigeration.
Technical
Evaporative cooling removes heat through the latent heat of vaporization, lowering ambient temperature by 10–15 °C in arid climates. Brine solutions depress the freezing point of water via NaCl solvation, enabling sub‑freezing storage of root vegetables. Ice packs provide a direct heat sink, while thermoelectric coolers convert solar energy into a temperature gradient to maintain 4 °C.
