How Was A Refrigerator Originally Invented?

The history of refrigeration dates back to the 17th century when the first mechanical refrigeration machines were invented. The first working refrigeration system was invented by Scottish professor William Cullen in 1748. He used a vacuum pump to create a partial vacuum in a container, which caused the evaporation of the liquid inside the container to absorb heat from the surroundings, thus cooling the container and its contents.

The first commercially successful refrigerator was invented by Jacob Perkins in 1834, who used a compressed-air system to produce a cooling effect. Meanwhile, in 1842, Florida physician John Gorrie invented a cooling machine to help produce ice for cooling and preserving food and medicine in hot climates, leading to the invention of the ice machine, which was essential in the development of modern refrigeration.

Another important milestone was reached in 1876 when German engineer Carl von Linde developed the first practical ammonia-compression refrigeration system, which was widely adopted in the food and beverage industries.

The first electric refrigerator for domestic use was invented in 1913 by American engineer Nathaniel B. Wales, who used an electric compressor and a condenser to cool the refrigerator's interior. In 1923, General Electric introduced the "Monitor-Top" refrigerator, which became the first widely successful electric refrigerator.
