Main / What is a zero energy cold chamber?

Fresh fruit and vegetable spoilage is a serious problem in tropical countries. Cool storage can extend the life of fresh products, but refrigerators are expensive to purchase, expensive to run, and expensive to maintain. However, there is a practical, inexpensive alternative to farm fruit and vegetable storage that uses the cooling power of evaporation. And they are easily made from locally available materials like brick, sand, bamboo, straw, and burlap.

Fresh fruits and vegetables are alive. They breathe and ripen even after the harvest. Cool temperatures stew this process so you can keep your fresh produce longer and avoid spoilage. Make a floor with bricks. Set up a 70 cm high double wall and leave a cavity 7 free.

Soak the chamber with water. Fill the cavity between the double wall with this damp sand. Make a cover frame out of bamboo. Build a thatched roof shed over the chamber to protect the chamber from direct sun and rain. A drip system can be built from plastic pipes and microtubes connected to an overhead source of water.

Do not use bamboo, wood or fiberboard boxes as these will be damaged by moisture. Water twice a day. Irrigation with a drip system. Cover these boxes with a thin polyethylene film.

Rebuild the chamber with new bricks after 3 years. The pores of the bricks become clogged over time and this reduces the effectiveness of the chamber.

Build your chamber in a place where there will be a breeze. Build on a raised construction site to avoid waterlogging. Use clean, unbroken stones with good porosity. Sand should be clean and free of organic matter, clay, etc. Keep the bricks and sand saturated with water. Prevent water droplets from coming into contact with stored products.

Keep the chamber clean. The empty chamber should be treated with an approved fungicide and insecticide.
