Zero Energy Brick Cooler (ZEBC)

Abstract

It is a low cost postharvest temperature manage-ment that improves the shelf-life of banana using less power. Its evaporative cooler works on the principle of cooling resulting from evaporation of water from the surface of porous materials such as sand or bricks. Hot dry air is drawn over the porous material. The water evaporates into the air using latent heat of evaporation, raising its humidity and at the same time reducing the temperature of the air within the chamber compared to the ambient (environment) temperature.
