Introduction:

Refrigerator is a kind of refrigeration equipment to keep a constant low temperature, and it is also a civilian product to keep food or other items at a constant low temperature. There are compressors, ice makers, cabinets or boxes for refrigeration, and there are storage boxes with refrigeration devices in the boxes.

Historical origin:

Humans have long known that food stored at low temperature is not easy to rot. Over 2000 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. In Shang dynasty (BC17th century, BC 1 1 century), China also knew how to keep food in ice. In the Middle Ages, many countries had primitive refrigerators, and put ice cubes in special water cabinets or stone cabinets to preserve food. Until the 65438+1950s, this kind of refrigerator was still sold in America.

Development process:

/kloc-in the middle of the 0/7th century, the word "refrigerator" entered the American language. Before that, refrigerators initially only affected the diet of ordinary Americans. With the development of the city, the sales of methamphetamine have gradually developed. It is gradually used by hotels, hotels, hospitals and some discerning city businessmen to keep meat, fish and butter fresh. After the civil war (186 1- 1865), ice was used to refrigerate freight cars and also entered civil use. Before 1880, half of refrigerators sold in new york, Philadelphia and Baltimore, and one third in Boston and Chicago began to be used in families, because a new household equipment-refrigerator-the predecessor of modern refrigerator was invented. Similar products include freezers.
