Iziqandisi zokushisa okuphansi kakhulu (ULT) zizuze ukunakwa okukhulu muva nje, ikakhulukazi ngenxa yendima yazo ebalulekile ekugcineni imigomo ye-COVID-19. Le mishini eyinkimbinkimbi ibalulekile ekulondolozeni izinto zebhayoloji ezingazweli ezingeni lokushisa, iqinisekise ubuqotho bayo phakathi nenkathi enwetshiwe. Ukuqonda ubuchwepheshe obungemuva kweziqandisi ze-ULT kubalulekile kubaphathi bamalebhu, ochwepheshe, nanoma ubani onentshisekelo kumasistimu wokuqandisa athuthukile. Kulesi sihloko, sizohlola ukusebenza okuyinkimbinkimbi kweziqandisi ze-ULT, ukusetshenziswa kwazo, nezici okufanele uzicabangele lapho ukhetha eyodwa yelabhorethri yakho. Kulabo abathanda ukuhlola izinketho ezihlukahlukene, ungathola ububanzi Amamodeli e-Ultra Low Freezer ayatholakala.
Ukuqonda Isiqandisi Esinesiteji Esisodwa
Ukuze uqonde ukuthi iziqandisi ze-ULT ziwathola kanjani amazinga okushisa aphansi kakhulu, kubalulekile ukuthi uqale uqonde izinhlelo zesiqandisi zesigaba esisodwa. Lezi zinhlelo zivame ukusetshenziswa eziqandisini zasendlini futhi zisebenza ngokucindezela isiqandisi esinegesi ukuze kwenyuswe ingcindezi nezinga lokushisa, ngokulandela umthetho ka-Amonton. Isiqandisi sibe sesigeleza ku-condenser, lapho sikhulula ukushisa futhi sishintshe sibe esimweni soketshezi. Lesi siqandisi esiwuketshezi sidlula endaweni yokomisa isihlungi ukuze sikhiphe ukungcola ngaphambi kokungena ku-evaporator. Ku-evaporator, isiqandisi sidonsa ukushisa okuvela egumbini lesiqandisi, sihwamuke sibuyele egesini futhi sipholise ikamelo ngesikhathi senqubo. Umjikelezo uyaphinda njengoba isiqandisi sibuyela ku-compressor.
Ifriji ye-Cascade enezigaba ezimbili
Iziqandisi ze-ULT zivame ukusebenzisa isistimu yesiqandisi enezigaba ezimbili, eyakhela phezu kwezimiso zezinhlelo zesigaba esisodwa. Kule sethaphu, amaluphu esiqandisi amabili asebenza ngokuhambisana, isiqandisi sesiteji sokuqala sipholisa isiqandisi sesigaba sesibili ngesishintshi sokushisa esiphakathi kwesiteji. Le ngxenye ivumela ukudluliswa kokushisa phakathi kwezigaba ezimbili ngaphandle kokuxuba amafriji. Isiqandisi sesigaba sesibili sidonsa ukushisa okuvela egumbini lesiqandisi, sifinyelela izinga lokushisa eliphansi kakhulu elidingekayo ukuze kugcinwe isampula ebucayi. Ukusebenza kahle kwesistimu ye-cascade nekhono lokufinyelela amazinga okushisa aphansi kuyenza ilungele iziqandisi ze-ULT.
Izingxenye Ezibalulekile Zeziqandisi ze-ULT
Izingxenye ezibalulekile ezimbalwa zenza iziqandisi ze-ULT zigcine izinga lokushisa eliphansi kakhulu. Ama-compressor nama-condensers abalulekile emjikelezweni wesiqandisi, amanye amamodeli asebenzisa i-compressor eyodwa enamandla amakhulu kanti amanye asebenzisa isistimu ye-cascade enama-compressor amabili. Ama-evaporator nezishintshisi zokushisa zenza kube lula ukudluliswa kokushisa, okuvumela iziqandisi ukuthi zimunce futhi zisuse ukushisa kahle. Iziqandisi ze-ULT nazo zisebenzisa iziqandisi ezithile, njengama-hydrocarbons afana ne-ethane ne-propane, aziwa ngokusebenza kahle kwawo kwamandla. Nokho, ngenxa yokuvutha kwazo, ezinye iziqandisi ezifana ne-nitrogen ne-methane ngezinye izikhathi zisetshenziswa ngokusekelwe ezidingweni zokuphepha.
Izicelo ze-ULT Freezers
Iziqandisi ze-ULT zibalulekile ezimbonini ezahlukahlukene, ikakhulukazi ezemithi, i-biotechnology, kanye nocwaningo. Adlala indima ebalulekile ekulondolozeni amasampula ezinto eziphilayo, njenge-DNA, i-plasma, nezicubu zesitho, ezibalulekile ku-genomics, i-cell biology, nocwaningo lwezokwelapha. Emkhakheni wezokwelapha, iziqandisi ze-ULT zigcina izinhlanganisela zemithi nemijovo, ziqinisekisa ukusebenza kwazo ngokugcina ukulawulwa kwezinga lokushisa okunembile. Nakuba zingajwayelekile kangako, iziqandisi ze-ULT nazo zisetshenziswa embonini yokudla ukuze kulondolozwe izinhlanzi ezisanda kubanjwa, zigcine ukwakheka kwazo kanye nekhwalithi yazo isikhathi eside.
Ukusebenza kahle kwamandla kanye nomthelela wemvelo
Iziqandisi zesimanje ze-ULT ziklanywe kucatshangwa ngokusebenza kahle kwamandla, zibhekana nokukhathazeka kokusimama kumalabhorethri. Iziqandisi ze-Hydrocarbon ezifana ne-ethane ne-propane zithandwa ngokusetshenziswa kwazo okuphansi kwamandla kanye nomthelela oncishisiwe wemvelo uma kuqhathaniswa neziqandisi ezindala. Amasistimu okulawula izinga lokushisa athuthukisiwe aqinisekisa amazinga okushisa angaguquguquki ngaphandle kokusebenzisa amandla amaningi, kuyilapho izitifiketi ezifana ne-Energy Star zibonisa amamodeli awonga amandla. Ngokukhetha iziqandisi ze-ULT ezonga amandla, amalebhu anganciphisa indawo yawo yemvelo kuyilapho egcina ukusebenza okuphezulu.
Isondlo Nokuphila Isikhathi Eside
Ukunakekelwa okufanele kubalulekile ukuze kuphile isikhathi eside nokusebenza kahle kweziqandisi ze-ULT. Ukuhlanzwa okujwayelekile kwamakhoyili nezihlungi ze-condenser kuvimbela ukunqwabelana kothuli nemfucumfucu, kuqinisekisa ukugeleza komoya ngendlela efanele. Ukuhlolwa njalo kwama-gaskets eminyango kanye ne-seal kubalulekile, njengoba izimpawu ezilimele zingaholela ekushintshashintsheni kwezinga lokushisa kanye nokwanda kokusetshenziswa kwamandla. Ukuqapha izinga lokushisa okungaguquki kusetshenziswa ama-thermometer edijithali noma amasistimu okuqapha kusiza ukuthola noma yiziphi izinkinga ngohlelo lwesiqandisi. Ukwengeza, ukusevisa okujwayelekile kwama-compressor nabalandeli kuvimbela ukwehluleka futhi kuqinisekisa ukusebenza kahle.
Ukukhetha i-ULT Freezer Engakwesokudla
Ukukhetha isiqandisi se-ULT esifanele kuhilela ukucabangela izici ezifana nomthamo wokugcina, ukwakheka kwelebhu, ukonga kwamandla, kanye nesabelomali. Nquma isampula yezidingo zesitoreji selebhu yakho bese ukhetha usayizi wesiqandisi ovumela kokubili izidingo zamanje nezesikhathi esizayo. Cabangela indawo yaphansi etholakalayo bese ukhetha phakathi kweziqandisi eziqondile nezisesifubeni ngokusekelwe ekuhlelweni kwelebhu yakho. Ukusebenza kahle kwamandla kubalulekile ekwehliseni izindleko zokusebenza nomthelela wemvelo, ngakho bheka amamodeli anezici zokonga amandla nezitifiketi. Ukucatshangelwa kwesabelomali, okuhlanganisa izinketho zokuthenga noma zokuqashisa, nazo zizoba nomthelela esinqumweni sakho.
Ukucatshangelwa Kokuphepha
Ukuphepha kubaluleke kakhulu uma usebenza neziqandisi ze-ULT ngenxa yamakhaza amakhulu eziwakhayo. Abasebenzi kufanele bagqoke amagilavu avaleleke nezingubo zokuzivikela ukuze bavikele ukusha okubandayo noma isithwathwa. Ikhophi yasenqolobaneni yamandla ezimo eziphuthumayo, njengejeneretha noma i-UPS, ibalulekile ukuze kugcinwe izinga lokushisa elizinzile phakathi nokucisha kukagesi. Izinqubo eziphephile zokuqeda isithwathwa, ukugwema izinto ezicijile, nokuqinisekisa ukugeleza komoya ngendlela efanele kanye nokungena komoya endaweni ezungezile kubalulekile ekuvimbeleni ukulimala kwemishini nokuqinisekisa ukusebenza kahle.
Amathrendi Azayo kuma-ULT Freezers
Njengoba ubuchwepheshe buthuthuka, iziqandisi ze-ULT ziba yinkimbinkimbi kakhulu, ezihlanganisa nezinto ezintsha ezithuthukisa ukusebenza kahle, ukusebenza, kanye nokusebenziseka kalula. Ubuchwepheshe obuhlakaniphile, njengamasistimu okuqapha akude, buvumela ukulandelela ngesikhathi sangempela sokusebenza kwesiqandisi nokushintshashintsha kwezinga lokushisa. Ukusebenza kahle kwamandla ngokuthuthuka kobuchwepheshe be-compressor noketshezi lwesiqandisi kunciphisa izindleko zokusebenza kanye nomthelela emvelweni. I-Automation kanye nokuhlanganiswa kwe-AI kunikeza ukuphathwa okuthuthukisiwe kwezinga lokushisa kanye namakhono okulungisa okubikezela. Iziqandisi ezilungele imvelo ezinamandla aphansi okufudumala kwembulunga yonke nazo ziyaduma, zihambisana nemigomo yokusimama.
Isiphetho
Iziqandisi ze-ULT zingamathuluzi abalulekile ezimbonini ezihlukahlukene, aqinisekisa ubuqotho bezinto eziphilayo ezizwelayo lokushisa. Ukuqonda ukusebenza kwazo, izingxenye ezibalulekile, nezinhlelo zokusebenza kusiza abaphathi bamalebhu bakhethe amamodeli angcono kakhulu ngezidingo zabo. Ukugcinwa ngendlela efanele kanye nokuhambisana nezimiso zokuphepha kuqinisekisa ukuphila isikhathi eside nokusebenza kahle kwale mishini eyinkimbinkimbi. Njengoba ubuchwepheshe buqhubeka nokuvela, iziqandisi ze-ULT zilungele ukusebenza kahle kakhulu futhi zibe nobungane bemvelo, zisekela isidingo esikhulayo socwaningo oluthuthukisiwe nezisombululo zokunakekelwa kwempilo. Ukuze uthole ulwazi olwengeziwe ngokukhetha ilungelo I-Ultra Low Freezer yelebhu yakho, hlola uhla lwethu lwezinketho.
