1, iqhwa elingaphezulu le-evaporator yesiqandisi lijiyile kakhulu noma linqwabelana kakhulu ngothuli, umphumela wokudlulisa ukushisa uyancipha
Ingqimba ikhulu kakhulu noma uthuli oluningi kakhulu lubangelwa. Njengoba izinga lokushisa eliphezulu le-evaporator yokugcina ebandayo lingaphansi kuka-0 ℃, kanye nomswakama ophezulu wendlu yokugcina impahla, umswakama emoyeni kulula kakhulu ukuwufaka eqhweni ebusweni be-evaporator, noma ngisho naseqhweni, okuthinta umphumela wokudlulisa ukushisa we-evaporator. Ukuze kuvinjelwe ukuthi ungqimba lweqhwa olungaphezulu lwe-evaporator lukhulu kakhulu, kubalulekile ukuluncibilikisa njalo.
Nazi izindlela ezimbili ezilula zokuncibilikisa: ① ukuvimba iqhwa. Okusho ukuthi, yeka i-compressor isebenze, vula umnyango oya endaweni yokugcina impahla, ukuze izinga lokushisa lendawo yokugcina impahla likhuphuke, ukuze lincibilike ngokuzenzakalelayo ungqimba lweqhwa, bese uqala kabusha i-compressor. ② Iqhwa. Ngemva kokukhipha izimpahla endaweni yokugcina impahla, ngqo ngamanzi ompompi okushisa okuphezulu ukuze ugeze ubuso be-evaporator tube, ukuze ungqimba lweqhwa luncibilike noma luwe. Ngaphezu kweqhwa elikhulu kuzoholela emphumeleni omubi wokudlulisa ukushisa kwe-evaporator, ubuso be-evaporator bukhulu kakhulu ngenxa yesikhathi eside ngaphandle kokuhlanza nokuqongelela uthuli, ukusebenza kahle kokudlulisa ukushisa nakho kuzoncishiswa kakhulu.
2, indawo yokugcina ebanda efrijini ngenxa yokushisa okuphansi noma ukusebenza kokuvala, okuholela ekulahlekelweni okukhulu kokushisa
Ukusebenza kabi kokufakwa kokushisa ngenxa yepayipi, ukujiya kwengqimba yokufakwa kodonga lokufakwa kokushisa akwanele, ukufakwa kokushisa kanye nomphumela wokufakwa kokushisa akubi, kuklanyelwe kakhulu ukukhetha ukujiya kwengqimba yokufakwa kokushisa akulungile noma ukwakhiwa kwekhwalithi yezinto zokufakwa kokushisa akubi. Ngaphezu kwalokho, enkambisweni yokwakha nokusetshenziswa, ukufakwa kokushisa kanye nokumelana nomswakama kungase kulinyazwe okuholela ekumswakama kwengqimba yokufakwa kokushisa, ukuguqulwa, noma ngisho nokuguqulwa kwe-vesiculation, ukufakwa kwayo kokushisa kanye nekhono lokulondolozwa kokushisa kwehle, ukulahlekelwa yibanda lendlu yokugcina kuyanda, ukwehla kwezinga lokushisa lomtapo wolwazi wokugcina obandayo esiqandisini kwehle kakhulu.
Esinye isizathu esibalulekile sokulahlekelwa ukubanda ukusebenza kahle kokuvala kwendlu yokugcina impahla, kunomoya oshisayo omningi ovela ekuvuza komoya ungene endlini yokugcina impahla. Ngokuvamile uma umugqa wokuvala emnyango wendlu yokugcina impahla noma uphawu lokuvala ukushisa olubandayo luvele lapho kuvela khona isimangalo samazolo, kukhombisa ukuthi uphawu aluqinile. Ngaphezu kwalokho, ukuvulwa nokuvalwa njalo komnyango wendlu yokugcina impahla noma abantu abaningi abangena ndawonye endlini yokugcina impahla nakho kuzokwandisa ukulahlekelwa ukubanda kwendlu yokugcina impahla. Kufanele uzame ukugwema ukuvula umnyango ukuze uvimbele umoya oshisayo omningi ungene endlini yokugcina impahla. Yiqiniso, indlu yokugcina impahla ingena njalo noma ingene esitokweni inkulu kakhulu, umthwalo wokushisa uyanda kakhulu, ukuze uphole kuze kufike ekushiseni okucacisiwe ngokuvamile kudinga isikhathi eside.
3, i-valve ye-throttle ayilawulwa kahle noma ivalekile, ukugeleza kwe-refrigerant kukhulu kakhulu noma kuncane kakhulu
Ivalvu yomphimbo engalawulwa kahle noma evalekile, izothinta ngqo ukugeleza kwe-refrigerant ku-evaporator. Uma ivalvu yomphimbo ivulekile kakhulu, ukugeleza kwe-refrigerant kukhulu, ingcindezi yokuhwamuka kanye nokushisa kokuhwamuka nakho kuyakhuphuka, izinga lokushisa lendawo yokugcina izinto lizonciphisa izinga lokwehla; ngesikhathi esifanayo, lapho ivalvu yomphimbo ivulekile incane kakhulu noma ivalekile, ukugeleza kwe-refrigerant nakho kuyancishiswa, amandla ohlelo lokuqandisa nawo ayancishiswa, izinga lokushisa lendawo yokugcina izinto lizonciphisa izinga elifanayo lokwehla.
Ngokuvamile ngokubheka ingcindezi yokuhwamuka, izinga lokushisa lokuhwamuka kanye neqhwa lepayipi lokumunca ukuze kunqunywe ukuthi ukugeleza kwe-throttle refrigerant kufanelekile yini. Ukuvaleka kwe-throttle kuyisici esibalulekile esithinta ukugeleza kwe-refrigerant, okubangela ukuvaleka kwe-throttle kuyimbangela eyinhloko ye-ice plug kanye ne-plug engcolile.
Ukuvaleka kweqhwa kungenxa yokuthi umphumela wokomisa womshini wokomisa awulungile, i-refrigerant iqukethe amanzi, igeleza nge-valve ye-throttle, izinga lokushisa lehla liye ngaphansi kuka-0 ℃, umswakama ongaphakathi kwe-refrigerant ungene eqhweni futhi uvimba imbobo ye-throttle; ukuvaleka okungcolile kungenxa ye-mesh yesihlungi se-throttle valve lapho kuqongelela inani elikhulu lokungcola, ukugeleza kwe-refrigerant akusheleli, ukwakheka kokuvaleka.
4, ukusebenza kahle kwe-compressor yefriji kuphansi, amandla efriji awakwazi ukuhlangabezana nezidingo zomthwalo wempahla yokugcina impahla
I-compressor yesiqandisi ngenxa yokusebenza kwesikhathi eside, i-cylinder liner kanye ne-piston ring nezinye izingxenye ngenxa yokuguga okukhulu, ngokuvuleka okwandisiwe, ukusebenza kokuvala kuzokwehla ngokufanele, i-coefficient yokudlulisa igesi ye-compressor yesiqandisisi nayo iyancipha, umthamo wesiqandisi uzoncishiswa. Uma umthamo wokupholisa ungaphansi komthwalo wokushisa wendlu yokugcina impahla, kuzoholela ekwehleni kancane kwezinga lokushisa lendlu yokugcina impahla.
I-compressor ingabonakala ngokusebenzisa ingcindezi yokumunca nokukhipha i-compressor, inquma cishe amandla okuqandisa e-compressor. Uma amandla okuqandisa e-compressor ehla, indlela evamile ukufaka esikhundleni se-compressor cylinder liner kanye ne-piston ring, uma ukufaka esikhundleni kungakasebenzi, kufanele kucatshangelwe ezinye izici, futhi kuqedwe ngisho nokulungiswa komshini, kuxazululwe izinkinga.
5, i-evaporator lapho kukhona umoya omningi noma uwoyela oqandisiwe, umphumela wokudlulisa ukushisa wehla
Uma ishubhu lokudlulisa ukushisa le-evaporator linamathele ebusweni bangaphakathi bamafutha aqandisiwe kakhulu, i-coefficient yalo yokudlulisa ukushisa izoncishiswa, okufanayo, uma kunomoya omningi eshubhu lokudlulisa ukushisa, indawo yokudlulisa ukushisa ye-evaporator iyancishiswa, ukusebenza kahle kokudlulisa ukushisa nakho kuzoncishiswa kakhulu, izinga lokushisa legumbi lokugcina izinto linciphise izinga lokwehla. Ngakho-ke, ekusebenzeni nasekugcinweni kwansuku zonke, kufanele kuqashelwe ukususwa ngesikhathi kwamafutha ongaphezulu eshubhu lokudlulisa ukushisa le-evaporator bese kukhishwa umoya eshubhuni lokukhipha ukushisa, ukuze kuthuthukiswe ukusebenza kahle kokudlulisa ukushisa kwe-evaporator.
6, inani le-refrigerant ohlelweni alanele, umthamo wokuqandisa alanele
Ukungapheleli kokujikeleza kwe-refrigerant kungenxa yezizathu ezimbili, esinye sazo ukuthi i-refrigerant ayinele, okwamanje, kudingeka nje ukuthi kulungiswe inani eliphelele le-refrigerant. Esinye isizathu ukuthi ukuvuza kwe-refrigerant ohlelweni kukhulu, kulokhu, kufanele uqale uthole iphuzu lokuvuza, ugxile ekuhlolweni kwepayipi, ukuxhumeka kwe-valve, ukuthola ukulungiswa kwendawo yokuvuza, bese ukhokhisa inani eliphelele le-refrigerant.
