- It was in 18th century that the process of invention of refrigerator started. In 1748 William Cullen (1710-1790) was a Scottish physician, chemist and professor of University of Glasgow who developed a process for creating an artificial cooling medium. No one took interest in it for commercial or home consumption, it only attracted scientific attention.
- An American inventor Oliver Evans (1755-1819) made the first design for the refrigerator in 1804 but until 1834 none was interested in the same. Jacob Perkins built the first refrigeration machine in 1834.
