Kuyinto evamile ukuthi izinga lokushisa le-freezer yesitolo esikhulu lingakwazi ukwehla futhi izinga lokushisa lehle kancane. Nasi ukuhlaziywa okufushane kwezizathu zokwehla kwezinga lokushisa kancane, ngethemba lokuletha usizo kubangani embonini efanayo.
1. Ngenxa yokungasebenzi kahle kokushisa noma ukusebenza kokuvala kwefriji, ukulahleka kwamandla okupholisa kukhulu
Isizathu sokuthi ukusebenza kokufakwa kokushisa kuphansi ukuthi ubukhulu bengqimba yokufakwa kokushisa yamapayipi, amabhodi okufakwa kokushisa, njll. akwanele, futhi umphumela wokufakwa kokushisa nokugcinwa kokushisa awulungile. Kubangelwa kakhulu ukukhethwa okungafanele kobukhulu bengqimba yokufakwa kokushisa ngesikhathi sokuklama noma ikhwalithi ephansi yezinto zokufakwa kokushisa ngesikhathi sokwakha. . Ngaphezu kwalokho, ngesikhathi senqubo yokwakha, ukufakwa kokushisa nokusebenza okuvikela umswakama kwezinto zokufakwa kokushisa kungalimala, okubangela ukuthi ungqimba lokufakwa kokushisa lube manzi, lukhubazeke, noma luguguleke. Esinye isizathu esibalulekile sokulahlekelwa okukhulu kokupholisa ukusebenza okungasebenzi kahle kokufakwa kokushisa, futhi umoya oshisayo omningi ungena ngenxa yokuvuza. Ngokuvamile, uma kukhona ukujiya emugqeni wokuvala womnyango noma uphawu lokufakwa kokushisa lwesiqandisi, kusho ukuthi uphawu aluqinile. Ngaphezu kwalokho, ukuvulwa nokuvalwa njalo kweminyango noma abantu abaningi abangena endlini yokugcina impahla ndawonye kuzokwandisa nokulahlekelwa amandla okupholisa. Ukuvula umnyango kufanele kugwenywe ngangokunokwenzeka ukuze kuvinjelwe inani elikhulu lomoya oshisayo ukuthi ungangeni. Vele, uma isitokwe sithengwa njalo noma inani elithengwayo likhulu kakhulu, umthwalo wokushisa uzokhula kakhulu, futhi ngokuvamile kuthatha isikhathi eside ukupholisa kuze kufike ezingeni lokushisa elibekiwe.
2. Iqhwa elisebusweni be-evaporator lijiyile kakhulu noma kunothuli oluningi kakhulu, futhi umphumela wokudlulisa ukushisa uyancipha.
Esinye isizathu esibalulekile sokwehla kwezinga lokushisa kancane ukusebenza kahle kokudlulisa ukushisa kwe-evaporator, okubangelwa kakhulu ungqimba olujiyile lweqhwa noma ukuqongelela kothuli oluningi ebusweni be-evaporator. Njengoba izinga lokushisa lobuso be-evaporator yesiqandisi liphansi kakhulu kune-0°C, futhi umswakama uphakeme kakhulu, umswakama emoyeni kulula ukuwuqandisa noma ngisho nokuwuqandisa ebusweni be-evaporator, okuthinta umphumela wokudlulisa ukushisa kwe-evaporator. Njengoba ijiyile kakhulu kunengqimba yeqhwa lobuso bedivayisi evimbela ukuhwamuka, idinga njalo ukuthi incibilikiswe.
Nazi izindlela ezimbili ezilula zokuncibilikisa:
① Vala ukuze uncibilikise. Okusho ukuthi, vala i-compressor, vula umnyango, vumela izinga lokushisa likhuphuke, bese uqala kabusha i-compressor ngemva kokuba ungqimba lwesithwathwa luncibilika ngokuzenzakalelayo.
②Isithwathwa. Ngemva kokukhipha izimpahla efrijini, hlanza ubuso bepayipi lokukhipha umoya le-evaporator ngqo ngamanzi ompompi ekushiseni okuphezulu ukuze uncibilikise noma uwe ungqimba lwesithwathwa. Ngaphezu komphumela omubi wokudlulisa ukushisa kwe-evaporator ngenxa yokuqandisa kakhulu, ukusebenza kahle kokudlulisa ukushisa kwe-evaporator kuzoncishiswa kakhulu ngenxa yokuqongelela kothuli olujiyile ebusweni be-evaporator ngenxa yokuhlanza isikhathi eside.
3. Kunomoya omningi noma uwoyela oqandisiwe ku-evaporator yesiqandisi sesitolo esikhulu, futhi umphumela wokudlulisa ukushisa uyancipha.
Uma uwoyela wefriji esenamathiselwe ebusweni bangaphakathi bepayipi lokudlulisa ukushisa le-evaporator, i-coefficient yayo yokudlulisa ukushisa izoncipha. Ngokufanayo, uma kunomoya omningi epayipini lokudlulisa ukushisa, indawo yokudlulisa ukushisa ye-evaporator izoncipha, kanye ne-coefficient yayo yokudlulisa ukushisa. Ukusebenza kahle nakho kuzoncipha kakhulu, futhi izinga lokwehla kwezinga lokushisa lizoncipha ngokufanele. Ngakho-ke, ekusebenzeni nasekugcinweni kwansuku zonke, kufanele kuthathwe ukunakekelwa kokususa uwoyela ebusweni bangaphakathi bepayipi lokudlulisa ukushisa le-evaporator bese ukhipha umoya ku-evaporator ngesikhathi ukuze kuthuthukiswe ukusebenza kahle kokudlulisa ukushisa kwe-evaporator.
Ukulungiswa okungalungile noma ukuvaleka kwevalvu ye-throttle kuzothinta ngqo ukugeleza kwe-refrigerant ku-evaporator. Uma ivalvu ye-throttle ivuliwe inkulu kakhulu, izinga lokugeleza kwe-refrigerant likhulu kakhulu, ingcindezi yokuhwamuka kanye nezinga lokushisa lokuhwamuka nakho kuzokwanda, futhi izinga lokwehla kwezinga lokushisa lizoncipha; ngesikhathi esifanayo, lapho ivalvu ye-throttle ivulwa incane kakhulu noma ivinjiwe, izinga lokugeleza kwe-refrigerant lizokhula. Amandla okupholisa esistimu nawo ancishisiwe, futhi izinga lokwehla kwezinga lokushisa lendlu yokugcina impahla nalo lizoncipha.
Ngokuvamile, kungahlulelwa ukuthi izinga lokugeleza kwe-refrigerant ye-throttle valve lifanelekile yini ngokubheka ingcindezi yokuhwamuka, izinga lokushisa lokuhwamuka kanye ne-frosting yepayipi lokumunca. Ukuvaleka kwe-throttle valve kuyisici esibalulekile esithinta izinga lokugeleza kwe-refrigerant, futhi izimbangela eziyinhloko zokuvaleka kwe-throttle valve ukuvaleka kweqhwa kanye nokuvaleka okungcolile. Ukuvaleka kweqhwa kungenxa yomphumela omubi wokomisa we-dryer. I-refrigerant iqukethe umswakama. Uma igeleza nge-throttle valve, izinga lokushisa lehla ngaphansi kuka-0°C, futhi umswakama ose-refrigerant uyaqina futhi uvale imbobo ye-throttle valve; ukuvaleka okungcolile kungenxa yokuqongelela kokungcola okwengeziwe kusihlungi sokungena se-throttle valve, ukujikeleza kwe-refrigerant akusheleli, okwenza ukuvaleka.
Ngaphezu kwalokho, ungatshela amakhasimende ezinye zezinyathelo zokuphepha zokusebenzisa ifriji:
1. Ifriji yokuthutha ibanga elide kufanele ibekwe amahora ama-2 ngaphambi kokuba ivulwe ukuze kuvinjelwe umonakalo ohlelweni ngenxa yokucindezela okukhulu. Ekusetshenzisweni kokuqala, vumela ikhabhinethi engenalutho isebenze ihora eli-1, bese ufaka izinto lapho izinga lokushisa ekhabhinethi lehla liye ezingeni lokushisa elidingekayo ekhabhinethini.
2. Izinto kufanele zihlukaniswe uma zifakwa. Uma ziminyene kakhulu, kuzothinta ukujikeleza komoya opholile.
3. Indawo ezungezile yefriji akufanele ibe seduze nomthombo wokushisa, ukuze kugwenywe ukukhanya kwelanga okuqondile futhi kuthinte umphumela wokupholisa.
4. Ngesikhathi senqubo yokuncibilikisa ngokuzenzakalelayo, izinga lokushisa ngaphakathi kwefriji lizokhuphuka ngesikhathi esifushane. Lapho umoya oshisayo ngaphandle kwekhabethe uhlangana nokudla okunobuso obubandayo, amazolo azoqina phezu kokudla. Iningi lamazolo lizosuswa lapho umshini uvulwa ukuze uqandiswe, kanti inani elincane lamazolo lizosala ekudleni, okuyinto evamile.
5. Ivalvu yenaliti ku-evaporator yesiqandisi isetshenziselwa ukuhlolwa kwesistimu kanye nokugcwalisa i-refrigerant, futhi akufanele ivulwe ngezikhathi ezivamile ukuvimbela ukuvuza kwe-refrigerant.
6. Ifriji akufanele igcine uketshezi namagesi avuthayo, aqhumayo nashintshashintshayo.
7. Isakhiwo seshelufu sefriji asikwazi ukuthwala isisindo esingaphezu kwama-50kg ngemitha yesikwele (kudingeka sisatshalaliswe ngokulinganayo), uma siningi kakhulu sizolimaza ishelufu.
8. Umhlabathi akufanele ube nokujula futhi kufanele ugcinwe uqondile, ngaphandle kwalokho kuzothinta ukugeleza kwamanzi. Ukugeleza kwamanzi okungekuhle kuzothinta ukupholisa okuvamile futhi kulimaze ifeni.
