Re­frig­er­a­tion

Australian T3 - - TABLET -

Gee­long may be most fa­mous for the Cats, but it’s also the birth­place of a cor­ner­stone of the Aus­tralian way of life: cold beer. Well, the cold part any­way. In 1854, Gee­long res­i­dent and Scot­tish-born Aus­tralian James Har­ri­son in­vented an ice-mak­ing ma­chine, which he de­vel­oped fur­ther to cre­ate a vapour-com­pres­sion re­frig­er­a­tion sys­tem the fol­low­ing year. The sys­tem used a com­pres­sor to force vapourised ether into a con­denser for cool­ing, turn­ing it back into liq­uid. This then passed through the re­frig­er­a­tion coils, chang­ing back into gas and cool­ing the sys­tem.

Al­though the tech­nol­ogy has been re­fined sig­nif­i­cantly since, Har­ri­son’s sys­tem is still the foun­da­tion for mod­ern re­frig­er­a­tion.
