Wonke umuntu uyazi ukuthi ukudla okusele ekushiseni okushisa ngokushesha kunalokho okushiye emakhazeni. Ngaphansi kwezimo eziphansi zokushisa, amabhaktheriya anciphisa umsebenzi wabo, futhi ukudla okubandayo kuqhubeka isikhathi eside kunokuba kusetshenziswe ekamelweni lokushisa. Ngisho nasezikhathini zasendulo, abantu baphawula ukuthi imikhiqizo eshiywe emthunzini iqhubeka isikhathi eside kunalabo abahlala elangeni. Futhi, abantu babone ukuthi esikhathini esibandayo impilo yokulala yamakethe kaningi kanyuke. Ngakho-ke, baqala ukucinga izindlela zokuxazulula inkinga yokulondoloza imikhiqizo ngamazinga aphansi okushisa.
Amanye ama-cellars asetshiwe, ngoba izinga lokushisa ngaphansi komhlaba liphansi kakhulu, ezinye imikhiqizo ye-obkladyvali neqhwa noma iqhwa. Ngisho nesimo sezulu esishisayo sogwadule, abantu ebusuku babelahlile amanzi ababeka kuyo ukudla ngalolo suku. Zonke lezi zindlela zaziphansi kakhulu ekulondolozweni kwemikhiqizo yeqandisini lesimanje, okwabonakala eminyakeni eminingi kamuva.
Ukhokho omdala kunesiqandisini samanje wakhululwa ngo-Agasti 17, 1816, kodwa kwakungasetshenziselwa ukusetshenziswa kwekhaya. Ukukhiqizwa kwezingqikithi zamafrijizi kwaqala e-US ngonyaka ka-1925, kanti e-USSR le nsiza yezindlu yasetshenziswa kubantu kuphela kusukela ngawo-1960. Iziqandisini zaseSoviet zazingenakubalwa futhi zisebenza kancane, kodwa zithembekile futhi zilula ukuzigcina.
Kusukela ngaleso sikhathi, isiqandisisi sishintshe kaningi. Ukuklama okuqhubekayo njalo nezimfanelo zobuchwepheshe. Kuze kube manje, ukhetho lwabo lukhulu kakhulu kangangokuthi abantu abaningi bavame ukuzibuza ukuthi iyiphi enye yokuthenga. Manje kungenzeka ukhethe isiqandisisi ngazo zonke izinambitheka, ezifanelekile ngaphakathi kwekhishi ngombala noma usayizi, kanye naseklasini lokugcina amandla kanye nohlobo lokushisa. Iziqandisini zanamuhla ziza izinhlobo ezimbili, zinyuka futhi zome. Eyokuqala yiziqandisisi ezijwayelekile ezidinga ukulungiswa okuvamile, ezinye azidingi inqubo enjalo.
Isistimu yeqhwa elomile yavela maduzane. Abantu bavame ukuzwa igama elidumile elithi "know frost", okuyinto wonke umuntu ahlobanisa neqhwa elithi frost eyomile. Nakuba ngesiNgisi le nkulumo izwakala - ayikho isithwathwa. Kulezi ziqandisisi, i-evaporator ifihliwe ngemuva kwodonga olungemuva noma ngaphezulu kwefriji futhi abalandeli abaningi noma ngaphezulu bahlale bekhona ukuze kuqinisekiswe ukuthi umoya obandayo ujikeleza njalo, ongena emakamelweni ngokusebenzisa iziteshi ezikhethekile. Lapho isiqandisini sisebenza, kubonakala umswakama, ongahlali emdongeni wekamelo ngobuningi beqhwa, kodwa uhlanganisa ingxenye ebanda kunazo zonke ye-evaporator. I-compressor ivaliwe ngezikhathi ezithile futhi i-hoarfrost, lapho ihlanganiswa khona, ihlanjululwa yi-heater encane eyenziwe ngaphambili, futhi umswakama obumbene uphuthuka.
Kuningi lamahemuhemu mayelana nezinzuzo nezingozi zeqhwa elomile. Kodwa iqiniso lokuthi uhlelo olunjalo selusetshenziswa kakade yiYurophu lonke liyazikhulumela. Isiqandisini akufanele sibe thawed, kodwa abantu abaningi abasebenzisayo, kanye nabakhiqizi ngokwabo batusa okungenani kanye ngonyaka, isiqandisisi sisaqhubeka sishaya ukuqinisekisa ukuthi sithatha isikhathi eside. Imikhiqizo kulezi ziqandisini ikhohliwe ngokushesha futhi ngokulinganayo, ibuye iqhwa, okuqinisekisa ukuthi kulondolozwa uhlobo, ukunambitheka, amavithamini namaminerali awusizo kuwo. Zonke izinhlobo zamajikijolo, imifino, inhlanzi nenyama, imifino eminingi ifaneleka iqhwa elomile. Into esemqoka akukona ukugcoba ukudla futhi, ngemuva kokuphazamiseka. Le ndlela yokulondoloza imikhiqizo ilula kakhulu futhi iwusizo kunamathanga, njengoba igcina imikhiqizo ngaphandle kokungeza izivimbela ezilimazayo ezifana noviniga, isibonelo, ithonya elilimazayo emzimbeni womuntu aludingi ubufakazi.
Abaningi bathi iziqandisini ezinezimo "ziyazi amaqhwa" ziyamemeza kakhulu ngomsebenzi wabalandeli. Lesi sitatimende asisebenzi kuwo wonke amamodeli. Abanye abakhiqizi basebenzisa abalandeli abasebenza ngokuthula kakhulu, noma kunjalo, lezi zithombe zibiza kakhulu. Enye inkinga ngamafriji ane-frost eyomile ukuthi ukudla okunomile kakhulu ukugwema lokhu, kudingeka ugobe ngokucophelela imikhiqizo efriziwe efrijini yeplastiki. Amafriji ane-froze eyomile adla amandla angaphezulu kuneziqandisisi ezinehlelo lokudonsa.
Mhlawumbe, lezi zonke zikhona ukwehluleka kokuqhwaba okumile. Kodwa uzohlale unethuba lokumangaza izivakashi ngaphansi konyaka omusha nge-strawberry eqoqwe ndawonye nensimu yazo engadini yabo.
