Humans have known from a very early age that preserving food at a low temperature is not easy to rot. Over 2111 BC, the ancient inhabitants of the Euphrates River and Tigris River basins in ancient Babylonia, West Asia, began to build ice cubes in pits to refrigerate meat. China also knew how to use ice cubes to refrigerate and preserve food in Shang Dynasty. In the Middle Ages, there were primitive refrigerators that put ice cubes in special water cabinets or stone cabinets to preserve food in many countries. Until the 1951s, this kind of refrigerator was still on sale in America.
