Editing Refrigeration (section)

==Current applications of refrigeration==
Probably the most widely used current applications of refrigeration are for [[air conditioning]] of private homes and public buildings, and refrigerating foodstuffs in homes, restaurants and large storage warehouses. The use of [[refrigerator]]s and walk-in coolers and freezers in kitchens, factories and warehouses <ref>{{Cite web|url=https://www.heatcraftrpd.com/productcatalog/familydetail.aspx?&FilterCol=&FilterVal=&LPNO=5&catID=HC113&pageNo=4&sort=Capacity+(BTUH)&cID=2|title=Heatcraft Refrigeration Products &#124; Heatcraft Worldwide Refrigeration|website=www.heatcraftrpd.com|access-date=2019-12-15|archive-date=2020-02-29|archive-url=https://web.archive.org/web/20200229150108/https://www.heatcraftrpd.com/productcatalog/familydetail.aspx?&FilterCol=&FilterVal=&LPNO=5&catID=HC113&pageNo=4&sort=Capacity+(BTUH)&cID=2|url-status=dead}}</ref><ref>{{Cite web|url=https://www.heatcraftrpd.com/productcatalog/familydetail.aspx?&FilterCol=&FilterVal=&LPNO=5&catID=HC058&pageNo=1&sort=Capacity+(BTUH)&cID=2|title=Heatcraft Refrigeration Products &#124; Heatcraft Worldwide Refrigeration|website=www.heatcraftrpd.com|access-date=2019-12-15|archive-date=2020-02-29|archive-url=https://web.archive.org/web/20200229140028/https://www.heatcraftrpd.com/productcatalog/familydetail.aspx?&FilterCol=&FilterVal=&LPNO=5&catID=HC058&pageNo=1&sort=Capacity+(BTUH)&cID=2|url-status=dead}}</ref><ref>{{Cite web|url=https://russell.htpg.com/unit-coolers/walk-in/|title=Russell - Walk-In|website=russell.htpg.com}}</ref><ref>{{Cite web|url=https://coldzone.htpg.com/unit-coolers/|title=Coldzone - Unit Coolers|website=coldzone.htpg.com}}</ref><ref>{{Cite web|url=https://www.heatcraftrpd.com/productcatalog/categorylist.aspx?catID=HC007&cID=4|title=Heatcraft Refrigeration Products &#124; Heatcraft Worldwide Refrigeration|website=www.heatcraftrpd.com|access-date=2019-12-15|archive-date=2019-12-15|archive-url=https://web.archive.org/web/20191215052523/https://www.heatcraftrpd.com/productcatalog/categorylist.aspx%3FcatID%3DHC007%26cID%3D4|url-status=dead}}</ref> for storing and processing fruits and vegetables has allowed adding fresh salads to the modern diet year round, and storing fish and meats safely for long periods.

In commerce and manufacturing, there are many uses for refrigeration. Refrigeration is used to liquefy gases – [[oxygen]], [[nitrogen]], [[propane]], and [[methane]], for example. In compressed air purification, it is used to [[condensation|condense]] water vapor from compressed air to reduce its moisture content. In [[oil refinery|oil refineries]], [[chemical plant]]s, and [[petrochemical]] plants, refrigeration is used to maintain certain processes at their needed low temperatures (for example, in [[alkylation]] of [[butene]]s and [[butane]] to produce a high-[[octane rating|octane]] gasoline component). Metal workers use refrigeration to temper steel and cutlery. When transporting temperature-sensitive foodstuffs and other materials by trucks, trains, airplanes and seagoing vessels, refrigeration is a necessity.

Dairy products are constantly in need of refrigeration,<ref name=":6" /><ref>{{Cite web |title=Keeping Dairy Foods Safe {{!}} American Dairy Association NE |url=https://www.americandairy.com/health-wellness/food-safety/ |access-date=2024-03-12 |website=American Dairy Association North East |language=en-US}}</ref> and it was only discovered in the past few decades that eggs needed to be refrigerated during shipment rather than waiting to be refrigerated after arrival at the grocery store. Meats, poultry and fish all must be kept in climate-controlled environments before being sold.<ref name=":7">{{Cite book |last=Crawley |first=Gerard M. |url=https://books.google.com/books?id=tQUlEAAAQBAJ&dq=%22Meats,+poultry+and+fish+all+must+be+kept+in+climate-controlled+environments+before+being+sold%22&pg=PA120 |title=Wind, Water And Fire: The Other Renewable Energy Resources |date=2021-02-25 |publisher=World Scientific |isbn=978-981-12-2593-2 |pages=120 |language=en}}</ref> Refrigeration also helps keep fruits and vegetables edible longer.<ref name=":7" />

One of the most influential uses of refrigeration was in the development of the [[sushi]]/[[sashimi]] industry in Japan.<ref>{{Cite web |last=Ahire |first=Niraj |date=2022-12-16 |title=A Study on Refrigeration |url=https://www.ijsr.net/archive/v3i5/MDIwMTMyMDQx.pdf |access-date=2024-03-12 |language=en}}</ref><ref>{{Cite web |last=Ahire |first=Niraj |date=2022-12-16 |title=Cryogenic Refrigeration |url=https://medium.com/@niraj.ahire19/cryogenic-refrigeration-a91eae4a877 |access-date=2024-03-12 |website=Medium |language=en}}</ref> Before the discovery of refrigeration, many sushi connoisseurs were at risk of contracting diseases. The dangers of unrefrigerated sashimi were not brought to light for decades due to the lack of research and healthcare distribution across rural Japan. Around mid-century, the [[Zojirushi]] corporation, based in Kyoto, made breakthroughs in refrigerator designs, making refrigerators cheaper and more accessible for restaurant proprietors and the general public.
