Technology has led to development of different types and grades of refrigerators. This article reviews traditional refrigerators and modern refrigerators.
These refrigerators were simply pots. They were made from clay soils. The pots were filled with clean water fetched from different sources like river, wells or boreholes. The pots were designed in such away that they were capable of keeping water at very low temperatures. Food stuffs such as meat, fruits etc were then immersed in the water to prevent them from decomposing.
