Who created the first artificial refrigeration system?

A refrigerator with or without a freezer is a major appliance designed for cooling and preserving foods. One of the essential advancements toward the invention of the refrigerator came when the refrigerated coil was invented by Ibn Sina in the 11th century. The refrigerated coil was used to condense vapors. William Cullen at the University of Glasgow demonstrated the first artificial refrigeration system in the year 1748. However, he never used his discovery for practical purposes. In the year 1805, US inventor Oliver Evans, designed the first refrigeration machine that didn’t use liquid and instead used vapour to cool. In 1834, Jacob Perkins built the first machine for practical refrigeration. US physician John Gorrie built a refrigerator in 1844 based on the design of Oliver Evans to produce ice for cooling the air for yellow fever patients.
