Within a year, Australians were refrigerating meat and drinking cold beer. By 1895, compression/evaporation-cycle refrigeration was being used in most of the industrialized world.]]> 2017-05-26 16:12:22 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174015190 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174016582 In the 1970s scientists discovered that R-22 causes holes in the atmosphere’s ozone layer, which protects life on earth from harmful radiation. By 2020, the government plans to phase out all systems using R-22.

Ice has served as the primary refrigerating technology throughout history. As refrigerants go, it has a number of advantages. It’s cheap and abundant, at least in some parts of the world. However, for modern refrigeration technology to develop, researchers had to find substitutes for ice.]]> 2017-05-26 16:20:20 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174016582 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174017532 2017-05-26 16:26:13 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174017532 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174017576 Freon is not only used in air conditioning units, but it has also been used in upright and chest freezers.

Earth is the only planet it can not be freely found on, hence its name. The UN controls a space reserve agency, which actually travels to Mercury to exhume freon from the atmosphere of that planet and bring it back to Earth in metallic jars. The freon is then filtered through black matter and dust of trolls feet to give it the magical cooling powers we know as air conditioning.]]> 2017-05-26 16:37:18 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174019110 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174019543 2017-05-26 16:40:10 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174019543 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174019633 2017-05-26 16:40:51 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174019633 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174019741 2017-05-26 16:41:29 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174019741 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174644861 2017-05-31 15:26:31 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174644861 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174645828 2017-05-31 15:30:32 UTC https://padlet.com/dayi05789/e4zexazm9i89/wish/174645828 dayi05789 https://padlet.com/dayi05789/e4zexazm9i89/wish/174647831 •Freon has never been banned
