- REFRIGERATOR The earliest method of refrigeration was the storage of food in caves and cold springs . This method of storing food in cold places slowly evolved, as people began keeping food in their cellars , in their outdoor window boxes, in the snow, or underwater in nearby lakes, streams or wells. The invention of the icebox led to more efficient refrigeration. Ice was delivered to houses by delivery men and was used in wooden iceboxes that were lined in tin or zinc and insulated with sawdust or seaweed. The use of ice for refrigeration continued until World War I, when mechanical refrigeration came on the market. The first electric refrigerators with freezer compartments came on the market in the 1920s and 1930s . However, the mass production of refrigerators began after World War II, when researchers had been able to successfully adapt large refrigeration systems for use in homes and shops. In the 1950s and 1960s, the invention of automatic defrost and automatic ice makers further improvec I the efficiency of refrigerators Refrigerators also became available in a wide variety of size, color, and design. OTBeTbTe Ha Bonpoc What were the major developments in refrigeration after the ice box?
