Iziqandisi zezinga lokushisa eliphansi kakhulu (ULT) zibalulekile kulabhorethri, izindawo zokugcina izinto eziphilayo, kanye nasezibhedlela zocwaningo. Badlala indima ebalulekile ekulondolozeni impilo yeshalofu yamasampula ebhayoloji njengama-enzyme, izicubu, amagciwane, nemithi yokugoma. Lezi ziqandisi zinikeza ukulawula ukushisa okunembe kakhudlwana nokunokwethenjelwa kuneziqandisi ezivamile, ezigcina izinga lokushisa eliphansi kakhulu, ngokuvamile eliphakathi kuka-50°C no-86°C. Iziqandisi ze-ULT zibalulekile kusayensi yempilo nasezinkundleni zocwaningo lwezokwelapha, kodwa zidinga ukunakekelwa ngokucophelela ukuze zisebenze kahle. Ukuze uthole ukwaziswa okwengeziwe I-Ultra Low Freezer , hlola umhlahlandlela wethu obanzi.
Ukukhetha Isiqandisi Sezinga Eliphansi Lokushisa Eliphansi Esilungile
Lapho ukhetha isiqandisi se-ULT, imibandela ogxila kuyo izoncika ezidingweni zokugcina amasampula akho ngokuphephile. Ubukhulu besiqandisi bunqunywa umthamo wokuwugcina owudingayo kanye nesikhala esitholakala endaweni yakho. Iziqandisi ze-ULT ezimile ngokuvamile zivumela indawo yokugcina okuningi ngaphandle kokuthatha indawo enkulu yaphansi. Uma ungahlelile ukugcina inani elikhulu lamasampuli noma ungasebenzi ngamasampula amakhulu, iziqandisi ezincane zingafeza injongo yakho ngempumelelo.
Ibanga lokushisa lingesinye isici esibalulekile ekukhetheni isiqandisi se-ULT. Okukhethayo kufanele kuncike ezinhlotsheni zamasampuli ohlela ukuwagcina, njengoba amanye amasampuli adinga ngisho namazinga okushisa aphansi kunamanye. Iziqandisi ze-Stirling Ultracold ULT zinikeza ibanga lokushisa elivuleke kakhulu elisebenzisekayo ngokusekela ama-setpoints azinzile phakathi kuka- -20°C no -86°C.
Imikhuba Engcono Kakhulu Yokuphatha Isiqandisi Sezinga Eliphansi Lezinga Eliphansi Lezinga Eliphansi Lokushisa
Ukuphatha kahle isiqandisi se-ULT kuyisihluthulelo sokukhulisa impilo yaso nokusebenza kahle. Ngokuhlala ngaphambi kwezinselele ezihlobene nesiqandisi se-ULT, ungaqinisekisa ukuthi sisethiwe futhi sigcinwe ngendlela efanele ukuze sisebenze ngokuqhubekayo nokusebenza kahle.
Cabangela Ukubekwa Kwefriji Nezidingo Zengqalasizinda
Esinye sezinyathelo ezibaluleke kakhulu lapho uthenga isiqandisi se-ULT ukuqinisekisa ukuthi indawo yesikhungo ihlomele kahle ukusingatha isiqandisi esikhulu, esinamandla amakhulu. Ukugcina izinga lokushisa eliphansi kakhulu kudinga amandla abalulekile. Qinisekisa ukuthi umthombo wakho wamandla ohleliwe uhlinzeka ngogesi owanele futhi ofanele wemodeli yesiqandisi ekhethiwe futhi ngeke ulayishwe kakhulu amadivayisi amaningi anamandla amakhulu. Amanye amamodeli we-ULT, njengamayunithi e-Stirling, angasebenza ngama-voltage amaningi, agweme ukuphinda kufakwe izintambo futhi enze kube lula ukuhambisana nezidingo zamandla ahlukahlukene emhlabeni wonke. Amandla ekhophi yasenqolobaneni ngokuvamile ayadingeka ukuze kugwenywe ukulahlekelwa kwenani eliphezulu futhi ngezinye izikhathi izimpahla zebhayoloji ezingabuyiseleki ezigcinwe kuziqandisi ze-ULT.
Iziqandisi ze-ULT nazo zingakhiqiza inani elikhulu lokushisa, okusho ukuthi ukuba neziqandisi eziningi endaweni eyodwa kungenza ukupholisa kube nzima nakakhulu. Amamodeli amaningi esiqandisi e-ULT kufanele asebenze endaweni yezinga lokushisa elingeqi ku-32°C, nakuba amamodeli e-Stirling angasetshenziswa ngokuphephile emazingeni okushisa angaphezu kuka-35°C. Isikhala esanele sesiqandisi sivumela ukugeleza komoya okusizungezile kanye nokungena komoya, okubalulekile ekusebenzeni kahle. Iziqandisi eziqinisekisiwe ze-ENERGY STAR® zinenzuzo njengoba zikhiqiza ukushisa okuncane futhi zinganciphisa izidingo ze-HVAC.
Amandla eFreezer Okugcina Izinto
Iziqandisi eziphansi kakhulu zisebenza kahle kakhulu lapho umoya obandayo ngaphakathi ungaphazamiseki futhi nesikhala sokugcina sikhulisiwe. Izinto zesampula kufanele zihlelwe kahle futhi ziphathwe efrijini ukuze kube lula ukubuyiswa futhi kuqinisekiswe isikhathi esifushane kakhulu sokuthi umnyango uhlale uvuliwe. Izimpahla zaselabhorethri nezinto zokwakha akufanele zipakishwe phezu kwesiqandisi, esingavalela umoya ofudumele, okubangele ukusebenza kahle kwesiqandisi kwehle ngokuhamba kwesikhathi.
Ukuqapha Izinga lokushisa kanye Neziloga Zedatha
Ama-ULT amaningi anesistimu eyakhelwe ngaphakathi yokuqapha izinga lokushisa, okuhlanganisa ama-alamu aphezulu naphansi kanye nabalogger bedatha. Izinhlelo zokuqapha ezikude nezisekelwe emafini zingakuxwayisa ngocingo noma nge-imeyili uma izinga lokushisa lekhabhinethi liphezulu kakhulu futhi likwazise uma ukubuyiselwa kwezinga lokushisa kuyadingeka ukuze ukwazi ukuthatha isinyathelo ngokushesha. Kungenzeka futhi ukuthi uthuthukele kumasistimu athuthuke kakhulu afaka ukupholisa okuyisipele nama-alamu okushisa azungezile.
Ukwenza Isondlo Esijwayelekile
Njengazo zonke izisetshenziswa zelebhu, ukwenza ukunakekelwa kokuvikela kuhamba ibanga elide ekulondolozeni okokusebenza kanye nokuqinisekisa ukuthi kuyaqhubeka nokusebenza ngempumelelo. Imisebenzi yokunakekela ihlanganisa ukuhlanza njalo nokushintsha isihlungi se-condenser, ukumisa isiqandisi ngokujwayelekile, nokulinganisa isiqandisi sakho njalo.
Hlanza Iyunithi Yakho Njalo
Kumayunithi asuselwa ku-compressor, uthuli luvame ukugcwala ku-condenser. Ukuhlanza isihlungi se-condenser kuqinisekisa ukuthi isiqandisi singapholisa kahle amasampula. Ungaqasha isevisi yokuhlanza isihlungi, noma ungakwazi ukucofa eduze kwamakhoyili e-condenser ngokwakho bese uyasikhipha futhi uhlanza isihlungi.
I-De-icing kanye ne-Defrosting Isiqandisi Sakho
Ukusiqandisa njalo/ukukhipha uiqhwa isiqandisi nakho kuwukhiye efrijini lakho le-ULT lisebenza kahle. Ukwakhiwa kweqhwa efrijini kungalimaza iminyango yangaphakathi, kubangele umshini osebenza kanzima ukuba ushise ngokweqile, futhi ubeke amasampula akho abalulekile engcupheni. Kufanele unciphise ifriji njengoba kudingeka futhi uhlele ukuqeda ifriji izikhathi ezimbili kuya kwezimbili ngonyaka.
Linganisa Isiqandisi Sakho
Ukusetshenziswa okuqhubekayo kungabangela isistimu yokuqapha yesiqandisi kanye nama-probe ukuthi anganembi kangako. Isiqandisi kufanele silinganiswe kaningi njengoba kushiwo inqubo yokusebenza evamile (SOP), kodwa ngokuvamile kanye ngonyaka kwanele.
Isiphetho
Iziqandisi zezinga lokushisa eliphansi kakhulu zibalulekile ekulondolozeni izinto zebhayoloji zocwaningo nezinjongo zomtholampilo. Ukukhethwa okufanele, ukubekwa, nokugcinwa kahle kwalezi ziqandisi kuqinisekisa ukusebenza kahle kwazo nokuphila isikhathi eside. Ngokulandela izinqubo ezingcono kakhulu zokuphatha iziqandisi ze-ULT, amalabhorethri angakwazi ukuvikela amasampula awo abalulekile futhi agcine ubuqotho bocwaningo lwawo. Ukuze uthole ukwaziswa okwengeziwe I-Ultra Low Freezer , vakashela insiza yethu enemininingwane.
