Lapho izinga lokushisa lokuhwamuka kwesistimu yesiqandisi yokugcina ebandayo lingaphansi kuka-0 ° C, kuzovela ungqimba lwesithwathwa ebusweni be-evaporator, okuthinta ukusebenza kahle kokudlulisa ukushisa.Ngakho-ke, ukuchithwa okuvamile kuyingxenye ebaluleke kakhulu yokugcina isitoreji esibandayo.Ziningi izindlela zokuncibilika.Njengamanje, abakhiqizi bokwakha isitoreji esibandayo ikakhulukazi basebenzisa izindlela ezinhlanu: ukucwiliswa kokufakelwa, ukuchithwa kukagesi, ukuqeda umoya oshisayo, ukuchithwa kwamanzi, ukuchithwa kwamanzi okushisa.
1. Ukususa isithwathwa okwenziwa ngesandla wukukhipha mathupha ungqimba lwesithwathwa ebusweni beshubhu yokukhipha umhwamuko.Le ndlela ingenziwa ngaphandle kokumisa imishini yesiqandisi.Le ndlela idla isikhathi futhi inzima, futhi umphumela wokuqeda iqhwa awubi.
2. I-defrosting kagesi ukufaka isifudumezi sikagesi ku-evaporator ukuze sincibilike ngokushisisa ngogesi.Ngesikhathi sokunciphisa, misa i-compressor noma yeka ukuphakela uketshezi ku-evaporator.I-defrosting kagesi inezinzuzo zezindleko eziphansi nokulawula okulula, kodwa izindleko zokusebenza ziphezulu.Ivamise ukusetshenziselwa ukuncibilikisa okokugcina izinto ezibandayo, hhayi ukuncibilikisa okokusebenza kwesiqandisi.Emazingeni okushisa ahlukene, izidingo zamakhono okushisa kumele zehluke, namandla okupholisa adingekayo nawo kumele ahluke.Ukusungulwa kwesitoreji esibandayo kudinga ukwenziwa ngokwezifiso ngokuya ngendawo yesicelo sangempela sekhasimende kanye nesicelo, ngaphandle uma singekho isidingo esikhethekile sokuthatha umgwaqo wokulinganisa.
3. I-Hot gas defrosting ukusetshenziswa kwe-steam yesiqandisi esishisa kakhulu esikhishwa yi-compressor ukukhulula ukushisa ku-evaporator futhi kuncibilikise ungqimba lwesithwathwa ebusweni be-evaporator.I-hot gas defrosting system iyinkimbinkimbi futhi izindleko ziphezulu.Kodwa umphumela we-defrosting ungcono.Uma isetshenziswa ohlelweni lwe-ammonia, uwoyela oqoqwe ku-evaporator nawo angakhishelwa ku-drain noma endaweni yokugcina ingcindezi ephansi.Enqubweni yokuqothula igesi eshisayo, ingcindezi ngokuvamile ilawulwa ku-0.6MPa.Zama ukusebenzisa igesi enomfutho ophezulu okhishwe ku-compressor yesiteji esisodwa ukuze unciphise uqhwa.Ubusika bungafaneleka ukunciphisa amanzi okupholisa noma ukunciphisa inani lama-condensers, ukwandisa izinga lokushisa lokukhipha, unciphise isikhathi sokuqhaqhazela.Kuzinhlelo ze-ammonia, i-ammonia eshisayo yokunciphisa iqhwa kufanele ixhunywe kwipayipi yokukhipha yesihlukanisi samafutha.
4. Ukuncibilikisa amanzi ukufafaza amanzi phezu kwe-evaporator ngomshini wokufafaza ukuze kuncibilike ungqimba lwesithwathwa.Uhlelo lokunciphisa amanzi lunesakhiwo esiyinkimbinkimbi nezindleko eziphezulu, kodwa umphumela omuhle kanye nezindleko eziphansi.Ukunciphisa amanzi kungasusa kuphela ungqimba lwesithwathwa endaweni engaphandle ye-evaporator, futhi akukwazi ukuxazulula umphumela omubi wokunqwabelana kwamafutha ku-evaporator ekudlulisweni kokushisa.Into ebaluleke kakhulu ibhodi lokugcina elibandayo, elivame ukukhiqizwa kusengaphambili ngumkhiqizi webhodi lokugcina elibandayo futhi linobude obunqunyiwe, ububanzi nobukhulu.Ibhodi lokugcina elibandayo elingu-100mm livame ukusetshenziselwa ukugcinwa kwamakhaza aphakeme naphakathi nendawo, ibhodi lokugcina elibandayo elingu-120mm noma elingu-150mm livame ukusetshenziselwa ukugcina izinga lokushisa eliphansi kanye nesitoreji esiqandisayo.
5. I-hot air defrosting yizindlela ezimbili zokuncibilika okushisayo kanye ne-water defrosting ezisetshenziswa ngesikhathi esifanayo, ezigxilisa izinzuzo zakho kokubili, futhi zingasusa ngokushesha futhi ngempumelelo ungqimba lwesithwathwa ebusweni be-evaporator futhi kuqede ukuqoqwa kwamafutha. ngaphakathi kwe-evaporator.Lapho i-defrosting, igesi eshisayo iqala ukuthunyelwa ku-evaporator ukuze ihlukanise ungqimba lwesithwathwa ebusweni be-evaporator, bese amanzi efafazwa ukugeza ngokushesha ungqimba lwesithwathwa.Ngemva kokunqunywa kwamanzi, ingaphezulu le-evaporator "lomiswa" ngomoya oshisayo ukuvimbela ifilimu yamanzi angaphezulu ekuqandisweni futhi ithinte ukudluliswa kokushisa.Esikhathini esedlule, abakhiqizi bebhodi lokugcina abandayo babesebenzisa i-polyethylene ne-polystyrene njengezinto zokwakha.Manje kukhona ukusebenza okungcono kwe-polyurethane sandwich board.I-Polystyrene foam insulation material iphansi, ayikwazi ukugqunywa.Ngokuvamile zisetshenziswa emishinini ekhethekile.I-Polyethylene iyimpahla enhle eluhlaza.Ngokusebenzisa isilinganiso esithile, kungenziwa foamed aphume ukuminyana ezifanele, ukwahlukanisa umphumela muhle, eqinile ukuthwala umthamo we impahla ukwahlukanisa.Ipuleti ye-polyurethane ingcono, inomsebenzi ongcono wokufaka umswakama futhi ayimumbi umswakama, kodwa le ntengo yokugcina ebandayo iphakeme kancane.
