What is the origin of fridge?

Answer 1

The origin of the refrigerator dates back to the mid-18th century when scientists began experimenting with refrigeration principles. The first artificial refrigeration was created in 1755 by Scottish professor William Cullen, who demonstrated the evaporation of ether to produce cooling. The modern refrigerator, as we know it, emerged in the early 20th century with the development of vapor-compression refrigeration systems, which became widely adopted for household use in the 1920s and 1930s. This innovation revolutionized food preservation and storage.
