Umthamo wesiqandisi awuhlangabezani nezidingo zomthwalo wendlu yokugcina impahla (ukusebenza kahle kwe-compressor okuphansi)
Kunezizathu ezimbili eziyinhloko zokuntuleka kwenani eliyindilinga le-refrigerant.
1 akwanele ukushaja i-refrigerant, kulokhu kuphela okudingekayo ukuze kulungiswe inani eliphelele le-refrigerant;
② esinye isizathu ukuthi ukuvuza kwe-refrigerant yesistimu kukhulu, kufanele kutholakale lesi simo kuqala, kugxilwe ekuhlolweni kwepayipi, ukuxhumeka kwe-valve, ukuthola ukulungiswa kwendawo yokuvuza, bese ukhokhisa inani eliphelele le-refrigerant.
Ukuntuleka kwamandla okugcina isiqandisi (inani elanele lesiqandisi ohlelweni)
Ukuntuleka kwe-refrigerant eyanele ohlelweni kuzothinta ngqo ukugeleza kwe-refrigerant ku-evaporator.
Uma ivalvu yokwandisa ivuleka kakhulu, ivalvu yokwandisa ayilawulwa kahle noma ivalekile. Ukugeleza kwesiqandisi kukhulu, ingcindezi yokuhwamuka kanye nokushisa kokuhwamuka nakho kuyakhuphuka, izinga lokushisa lendawo yokugcina izinto lizonciphisa izinga lokwehla; ngesikhathi esifanayo, lapho ivalvu yokwandisa ivulwa incane kakhulu noma ivinjiwe, ukugeleza kwesiqandisi nakho kuyancishiswa, amandla esiqandisi sesistimu nawo ayancishiswa, izinga lokushisa lendawo yokugcina izinto nalo lizonciphisa izinga lokwehla. Ngokuvamile ngokubheka ingcindezi yokuhwamuka, izinga lokushisa lokuhwamuka kanye neqhwa lepayipi lokumunca ukuze kunqunywe ukuthi ukugeleza kwesiqandisi sevalvu yokwandisa kufanelekile yini.
Ukuvaleka kwevalvu yokwandisa kuyisici esibalulekile esithinta ukugeleza kwe-refrigerant, okubangela ukuvaleka kwevalvu yokukhulisa kuyisizathu esiyinhloko sokuvalwa kweqhwa kanye ne-plug engcolile. I-ice plug ngoba umphumela wokomisa owomisa awulungile, i-refrigerant iqukethe amanzi, igeleza nge-valve yokwandisa, izinga lokushisa lehla liye ngaphansi kuka-0 ℃, i-refrigerant emanzini iye eqhweni futhi ivale imbobo ye-throttle; i-plug engcolile ibangelwa i-interval valve inlet filter mesh equkethe ukungcola okuningi, i-refrigerant igeleza kahle, ukwakheka kokuvaleka.
Ukugeleza kwesiqandisi kukhulu kakhulu noma kuncane kakhulu (i-valve yokwandisa engalawulwa kahle noma evalekile)
I-coefficient yayo yokudlulisa ukushisa izoncishiswa, uma ishubhu lokudlulisa ukushisa le-evaporator linamathele ebusweni bangaphakathi bamafutha amaningi okupholisa. Ngokufanayo, uma kunomoya omningi eshubhu lokudlulisa ukushisa, indawo yokudlulisa ukushisa ye-evaporator iyancishiswa, futhi ukusebenza kwayo kahle kokudlulisa ukushisa kuzoncishiswa kakhulu, futhi izinga lokushisa legumbi lokugcina liyancipha. Ngakho-ke, ukusebenza nokugcinwa kwansuku zonke, kufanele kunake ukususwa ngesikhathi kweshubhu lokudlulisa ukushisa le-evaporator ngaphakathi kokubonakala kwamafutha bese kukhishwa umoya ku-evaporator, ukuze kuthuthukiswe ukusebenza kahle kokudlulisa ukushisa kwe-evaporator.
Umphumela wokudlulisa ukushisa uyancipha (i-evaporator ikhona emoyeni omningi noma uwoyela wokuqandisa)
Lokhu kungenxa yokuthi ungqimba lwangaphandle lweqhwa oluvela evaporator lujiyile kakhulu noma uthuli oluningi kakhulu olubangelwa yi-evaporator yokugcina ebandayo. Izinga lokushisa langaphandle le-evaporator liphansi kakhulu kune-0 ℃, okuholela ekwehleni kancane kwezinga lokushisa lomtapo wolwazi esinye isizathu esibalulekile sokuthi ukusebenza kahle kokudlulisa ukushisa kwe-evaporator kuphansi. Umswakama wendawo yokugcina impahla uphakeme kakhulu, umswakama emoyeni kulula kakhulu eqhweni langaphandle le-evaporator, noma ngisho naseqhweni, okuthinta umphumela wokudlulisa ukushisa we-evaporator. Ukuze kuvinjelwe ukuthi ingaphandle leqhwa le-evaporator lijiyile kakhulu, kudingeka ulincibilikise njalo.
Nazi izindlela ezimbili ezilula zokuncibilikisa:
① yeka iqhwa: okungukuthi, yeka i-compressor isebenza, vula umnyango oya endaweni yokugcina impahla, ukuze izinga lokushisa lendawo yokugcina impahla likhuphuke, ukuze lincibilike ngokuzenzakalelayo ungqimba lweqhwa, bese uqala kabusha i-compressor.
② Ukushawa kweqhwa: izimpahla ziphuma endlini yokugcina impahla, ngqo ngokushisa okuphezulu kwamanzi ompompi ukuze kushawa ubuso beshubhu le-evaporator, ukuze ungqimba lweqhwa luncibilike noma luwe. Ngaphezu kweqhwa elijiyile kuzoholela ekutheni umphumela wokudlulisa ukushisa kwe-evaporator awumuhle, ukubukeka kwe-evaporator ngenxa yokuhlanza kwesikhashana kanye nokuqongelela uthuli kukhulu kakhulu, ukusebenza kahle kokudlulisa ukushisa nakho kuzoncishiswa kakhulu.
Ukwehla komphumela wokudlulisa ukushisa (isithwathwa esikhulu kakhulu noma ukuqongelela ngokweqile kothuli ngaphandle kwe-evaporator)
Ukufakwa kokushisa okubi kanye nomphumela wokulondolozwa kokushisa, umsebenzi wokufakwa kokushisa ompofu kungenxa yepayipi, udonga lokufakwa kokushisa lwendlu yokugcina impahla, njll., ukujiya kwesendlalelo sokufakwa kokushisa akwanele. Ngokuyinhloko ukwakheka kobukhulu besendlalelo sokufakwa kokushisa akulungile noma ukwakhiwa kwekhwalithi yezinto zokufakwa kokushisa kubi.
Ngaphezu kwalokho, inqubo yokwakha nokusetshenziswa, umsebenzi wokuvikela umswakama wokuvikela umswakama wokuvikela umswakama ungalimala okuholela ekutheni umswakama wongqimba lokuvikela umswakama, ukuguquguquka, noma ukubola, ikhono lawo lokuvikela ukufudumala linciphe, umtapo wolwazi wokulahlekelwa okubandayo uyanda, ukwehla kwezinga lokushisa lomtapo wolwazi kuyehla kakhulu.
Esinye isizathu esibalulekile sokulahlekelwa ukubanda umsebenzi wokuvala ompofu wendlu yokugcina impahla, kunomoya oshisayo omningi ovela emoyeni ovuza ungene endlini yokugcina impahla. Ngokuvamile, uma umugqa wokuvala emnyango wendlu yokugcina impahla noma udonga olushisayo lwendlu yokugcina impahla luvala isimo sokujiya, kubonisa ukuthi uphawu aluqinile.
Ngaphezu kwalokho, ukuvulwa nokuvalwa njalo komnyango wesitolo noma abantu abaningi ndawonye bangene esitokweni, kuzokwandisa nokulahlekelwa ukubanda kwesitolo. Kufanele uzame ukuvimbela ukuvulwa komnyango wesitolo ukuze uvimbele umoya oshisayo omningi ungene esitokweni. Yiqiniso, isitolo singene esitokweni njalo noma lapho inani lezimpahla likhulu kakhulu, umthwalo wokushisa uyanda kakhulu, ukuze uphole kuze kube yilapho izinga lokushisa lichazwa ngokuvamile kuthatha isikhathi eside.
Okubangela ukulahlekelwa okukhulu kokubanda (indawo yokugcina ebanda ngenxa yokungasebenzi kahle kokuvikela noma ukuvala)
Ama-cylinder liner nama-piston rings nezinye izingxenye ngenxa yokuguga okukhulu, i-compressor ngenxa yokusebenza kwesikhashana. Igebe lokulingana liyakhula, umsebenzi wokuvala uzokwehla ngokufanele, i-compressor gas transmission coefficient nayo iyancipha, umthamo we-friji uzoncishiswa. Uma umthamo we-friji ungaphansi komthwalo wokushisa we-warehouse, kuzoholela ekwehleni kancane kwezinga lokushisa le-warehouse. I-compressor ingabonakala ngokucindezela kokudonsa nokukhipha i-compressor cishe kunquma umthamo we-friji we-compressor. Uma umthamo we-compressor friji wehla, indlela evamile ukufaka esikhundleni se-compressor cylinder liner kanye ne-piston ring, uma ukushintshwa kusasebenza, kufanele kucabangele ezinye izici, futhi kuqedwe ngisho nokuhlolwa komshini, izici zokuxazulula izinkinga.
