Isiqandisi
siwumshini
wesiqandisi ogcina izinga lokushisa eliphansi njalo, futhi liphinde libe umkhiqizo ovamile ogcina ukudla noma ezinye izinto zisesimweni esisezingeni eliphansi. Ngaphakathi kwebhokisi kukhona i-compressor, ikhabethe noma ibhokisi ukuze umenzi weqhwa aqandwe, kanye nebhokisi lokugcina elinesiqandisi. Umthamo wamafriji kagesi wasendlini uvamise ukuba ngamalitha angama-20 kuye kwangama-500. Okulandelayo, ake sibheke umsuka womlando kanye nokuthuthuka kwe-

Umsuka womlando wefriji
Abantu bazi kusukela bebancane kakhulu ukuthi ukudla okugcinwa emazingeni okushisa aphansi akulula ukuthi konakale. Emuva kuka-2000 BC (ikhulu lama-20 BC), izakhamuzi zasendulo zemifula i-Ewufrathe neTigris eBhabhiloni, eNtshonalanga ye-Asia, zaqala ukwakha iqhwa emigodini ukuze zifake inyama efrijini. Ezikhathini Zobukhosi BamaShang (kusukela ekuqaleni kwekhulu le-17 BC kuya ekhulwini le-11 BC), iShayina futhi yayazi indlela yokusebenzisa iqhwa ukuze kulondolozwe ukudla. NgeNkathi Ephakathi, amazwe amaningi avela emazweni amaningi ukuze abeke ama-ice cubes emakhabetheni amanzi akhethekile noma amakhabethe amatshe ukuze alondoloze ukudla. Kuze kube ngawo-1850, lolu hlobo Isiqandisi Sesiqandisi Esiphezulu sathengiswa e-United States.
Igama elithi 'ifriji' alizange lingene olimini lwaseMelika kwaze kwaba maphakathi nekhulu le-17 eNtshonalanga. Ngokuthuthuka kwedolobha, ibhizinisi leqhwa liye lathuthuka kancane kancane. Kancane kancane yasetshenziswa amahhotela, amahhotela, izibhedlela, nabathengisi abathile basemadolobheni abanokuqonda ukuze kulondolozwe inyama, inhlanzi, nebhotela. Ngemva kweMpi Yombango YaseMelika (1861-1865 AD), iqhwa lalisetshenziswa emalolini afakwe esiqandisini, futhi lasetshenziswa nasemphakathini. Ngo-1880, ingxenye ye- Ifriji ye-Retro ethengiswa eNew York, Philadelphia, nase-Baltimore, kanye nengxenye eyodwa kwezintathu yamafriji athengiswa eBoston naseChicago yayingenile ekhaya. Imikhiqizo efanayo nayo inamafriji.
Ukwakha isiqandisi esisebenza kahle akulula njengoba sicabanga. Ekuqaleni kwawo-1800, abasunguli babenokuqonda okungajwayelekile kolwazi lwe-thermophysical olubalulekile kwisayensi yesiqandisi. Emazweni aseNtshonalanga, abantu babekholelwa ukuthi isiqandisi esingcono kakhulu kufanele sivimbele ukuncibilika kweqhwa, futhi umbono onjalo owawuvame kakhulu ngaleso sikhathi wawungalungile ngoba kwakuwukuncibilika kweqhwa okwakudlala indima yesiqandisi. Ngezinsuku zakuqala kwenziwa umzamo omkhulu wokulondoloza iqhwa, kuhlanganise nokusonga iqhwa ngezingubo zokulala ukuze iqhwa lingakwazi ukwenza umsebenzi walo. Kwaze kwaba ngasekupheleni kwekhulu le-19 lapho abasunguli baphumelela khona ekutholeni ibhalansi enembile ye-insulation kanye nokusabalalisa okudingekayo efrijini elisebenza kahle.
Inqubo yokuthuthukiswa kwefriji
Kodwa emuva ngo-1800, umlimi waseMaryland, uThomas More, wathola indlela efanele. Unepulazi eliqhele ngamamayela angu-20 ukusuka eWashington, lapho idolobhana laseGeorge Town liyisikhungo semakethe. Ngesikhathi ehambisa ibhotela emakethe nge Isiqandisi Esiphansi Sesiqandisi sedizayini yakhe, uthole ukuthi amakhasimende azodlula ibhotela elincibilika ngokushesha emabhakedeni esiqhudelana naye futhi amkhokhele imali engaphezu kwenani lemakethe laso lisasha, liqinile, futhi lisikwe ngobunono. Iphawundi lebhotela. UMoore uthi enye inzuzo yesiqandisi sakhe ukuthi abalimi akudingeki baye emakethe ebusuku ukuze bagcine umkhiqizo wabo upholile.
Ngo-1822, isazi sefiziksi esidumile saseBrithani uFaraday sathola ukuthi isikhutha, i-ammonia, i-chlorine, namanye amagesi azophenduka uketshezi ngaphansi kwezimo ezicindezelayo, futhi ayoba amagesi lapho ukucindezela kwehliswa. Enqubweni yokushintsha kusuka kuketshezi kuya kugesi, izomunca ukushisa okuningi, okubangela ukuthi izinga lokushisa elizungezile lehle ngokushesha. Lokhu okutholwe nguFaraday kunikeze isisekelo sethiyori ezizukulwaneni zakamuva ukuze zisungule ubuchwepheshe bokwenziwa kwesiqandisi obufana nama-compressor. I-compressor yokuqala yesiqandisi yokwenziwa yasungulwa ngu-Harrison ngo-1851. U-Harrison, umnikazi 'we-Geelong Advertiser' yase-Australia, wayehlanza uhlobo lwe-ether lapho ethola ukuthi noma kwakunomphumela onamandla wokupholisa ensimbi. I-Ether iwuketshezi olunephuzu lokubila eliphansi kakhulu, elijwayele ukuhwamuka kwe-endothermic phenomena. U-Harrison wenza ifriji esebenzisa i-ether kanye ne-a 3 Door Refrigerators pressure pump emva kocwaningo futhi yayisebenzisa endaweni yokwenza iwayini eVictoria, e-Australia, ukuze iphole futhi ipholiswe ngesikhathi sokwenza iwayini.
Ngo-1873, usokhemisi waseJalimane nonjiniyela uKarl von Linde wasungula isiqandisi esebenzisa i-fluorine njengesiqandisi. ULinde usebenzisa injini yesitimu encane ukushayela uhlelo lokuminyanisa, ukuze i-ammonia incindezelwe ngokuphindaphindiwe futhi ihwamuke ukuze ikhiqize isiqandisi. U-Linde waqale wasebenzisa ukusungula kwakhe endaweni yotshwala ye-Sedoumar e-Wiesbaden, waklama futhi wenza ifriji yezimboni. Kamuva, wathuthukisa ifriji yezimboni. Ukuze lenziwe libe lincane, ngo-1879, kwakhiqizwa isiqandisi sokuqala emhlabeni esiqandisiwe. esisebenza ngesitimu Isiqandisi safakwa ngokushesha ekukhiqizeni, futhi ngo-1891, kwase kudayiswe amayunithi angu-12 000 eJalimane nase-United States.
Injini yokuqala kagesi ukushayela i-compressor yasungulwa onjiniyela baseSweden u-Brighton noMendes ngo-1923. Inkampani yaseMelika kamuva yathenga amalungelo abo obunikazi futhi ngo-1925 yakhiqiza amafriji kagesi okuqala asendlini. Efrijini lokuqala likagesi, i-compressor kagesi nesiqandisi kwahlukaniswa. Lesi sakamuva sivamise ukufakwa kuhhavini ongaphansi komhlaba noma egumbini lokugcina impahla bese sixhunywa kumshini kagesi wokuminyanisa ngamapayipi. Kamuva, lezi ezimbili zahlanganiswa zaba yinto eyodwa. Ngaphambi kweminyaka yawo-1930, iziqandisi eziningi ezazisetshenziswa isiqandisi zazingaphephile , njenge-ether, i-ammonia, i-sulfuric acid, njll., zazivutha, zigqwala, noma zicasula. Kamuva, ngaqala ukucinga isiqandisi esiphephile futhi ngathola iFreon. I-Freon iyinhlanganisela ye-fluorine engenabuthi, engagqwali, engashi. Ngokushesha yaba isiqandisi semishini ehlukahlukene yokwenza iziqandisi futhi isisetshenziswe iminyaka engaphezu kuka-50. Kodwa kwatholakala ukuthi iFreon inomphumela olimazayo ongqimbeni lwe-ozone lomkhathi womhlaba. Ngakho abantu baqala ukufuna iziqandisi ezintsha nezingcono futhi.
