A concise historical narrative of NAICS Code 238210-33 covering global milestones and recent developments within the United States.

  • The refrigeration industry has a long and fascinating history, dating back to the 18th century when William Cullen, a Scottish physician, first demonstrated artificial refrigeration. In the 19th century, refrigeration technology advanced rapidly, with the invention of the first ice-making machine in 1854 and the first refrigerated rail car in 1867. The 20th century saw even more significant advancements, including the development of the first home refrigerators in the 1920s and the widespread use of air conditioning in the 1950s. In recent years, the refrigeration industry has continued to evolve, with a focus on energy efficiency and sustainability. In the United States, the industry has seen a shift towards natural refrigerants, such as carbon dioxide and ammonia, which have a lower environmental impact than traditional refrigerants like hydrofluorocarbons (HFCs).
