Umthamo wesiqandisi awukwazi ukuhlangabezana nezidingo zomthwalo wedepho (ukusebenza kahle kwe-compressor okuphansi)
Kunezizathu ezimbili eziyinhloko zokuntuleka kwenani lokujikeleza kwefriji. 
Esinye ukuthi ishaja yesiqandisi ayanele, okwamanje, kuyadingeka kuphela ukugcwalisa inani elanele lesiqandisi;
Esinye isizathu ukuthi kunokuvuza okuningi kwe-refrigerant ohlelweni, kulokhu, kufanele siqale sithole ukuvuza, sigxile ekuhloleni ukuxhumana kwepayipi kanye ne-valve, sithole ukuvuza bese sikulungisa, bese sishaja inani elanele le-refrigerant.
Ukuntuleka kwamandla okugcina isiqandisi (inani elanele lesiqandisi ohlelweni)
Inani elanele le-refrigerant ohlelweni lizothinta ngqo ukugeleza kwe-refrigerant ku-evaporator. Uma i-valve yokwandisa ivuleka kakhulu, i-valve yokwandisa ayilungiswa kahle noma ivinjiwe. Uma ukugeleza kwe-refrigerant kukhulu, ingcindezi yokuhwamuka kanye nezinga lokushisa lokuhwamuka kuzokhuphuka, futhi ukwehla kwezinga lokushisa kwendlu yokugcina kuzoncishiswa; okwamanje, lapho i-valve yokwandisa incane kakhulu noma ivinjiwe, ukugeleza kwe-refrigerant kuzoncishiswa, futhi amandla okugcina esistimu azoncishiswa, futhi ukwehla kwezinga lokushisa kwendlu yokugcina nakho kuzoncishiswa. Ngokuvamile, singabona ingcindezi yokuhwamuka, izinga lokushisa lokuhwamuka kanye neqhwa lepayipi lokudonsa ukuze sinqume ukuthi ukugeleza kwe-refrigerant kwe-valve yokwandisa kufanelekile yini. Ukuvaleka kwe-valve yokwandisa kuyisici esibalulekile esithinta ukugeleza kwe-refrigerant, futhi izizathu eziyinhloko zokuvaleka kwe-valve yokwandisa ukuvaleka kweqhwa kanye nokuvaleka okungcolile. Ukuvaleka kweqhwa kungenxa yokuthi umphumela wokomisa we-dryer awulungile, i-refrigerant iqukethe amanzi, futhi uma igeleza nge-valve yokwandisa, izinga lokushisa lehla liye ngaphansi kuka-0.℃, amanzi asefrijini azoba yiqhwa futhi avale imbobo yevalvu yomphini; ukuvaleka okungcolile kungenxa yokuthi isihlungi sokungena sevalvu yokwandisa siqukethe ukungcola okwengeziwe, kanti isiqandisi asigelezi kahle, okwenza ukuvaleka.
Ukugeleza kwesiqandisi kukhulu kakhulu noma kuncane kakhulu (i-valve yokunweba engalungiswanga kahle noma evinjiwe)
I-coefficient yayo yokudlulisa ukushisa izoncishiswa, uma ishubhu lokudlulisa ukushisa le-evaporator linamafutha amaningi esiqandisini anamathele ekubukekeni kwalo kwangaphakathi. Ngokufanayo, uma kunomoya omningi eshubhu lokudlulisa ukushisa, indawo yokudlulisa ukushisa ye-evaporator iyancishiswa, futhi ukusebenza kahle kokudlulisa ukushisa kwayo kuzoncishiswa kakhulu, futhi izinga lokushisa legumbi lokugcina izinto liyehliswa. Ngakho-ke, ukusebenza nokugcinwa kwansuku zonke, kufanele kunake ukusula ishubhu lokudlulisa ukushisa le-evaporator ngesikhathi esifanele ngaphakathi kokubonakala kwamafutha bese kukhishwa umoya ku-evaporator, ukuze kuthuthukiswe ukusebenza kahle kokudlulisa ukushisa kwe-evaporator.
Umphumela wokudlulisa ukushisa uyancipha (i-evaporator uma kukhona umoya omningi noma uwoyela oqandisayo)
Lokhu kungenxa yokuthi ungqimba lweqhwa lwangaphandle lwe-evaporator likhulu kakhulu noma uthuli oluningi kakhulu olubangelwa ukushisa kwangaphandle kwe-evaporator yokugcina ebanda kuphansi kakhulu kuno-0℃, okubangela esinye isizathu esibalulekile sokwehla kancane kwezinga lokushisa lomtapo wolwazi ukuthi ukusebenza kahle kokudlulisa ukushisa kwe-evaporator kuphansi. Futhi umswakama wendawo yokugcina impahla uphakeme kakhulu, umswakama emoyeni kulula kakhulu ukuwufaka eqhweni ngaphandle kwe-evaporator, ngisho naseqhweni, okuthinta umphumela wokudlulisa ukushisa we-evaporator. Ukuze kuvinjelwe ukuthi ungqimba lwangaphandle lwe-evaporator lube lukhulu kakhulu, ludinga ukuncibilikiswa njalo.
Nazi izindlela ezimbili ezilula zokuncibilikisa:
①yeka ukuncibilikisa iqhwa. Okusho ukuthi, yeka ukusebenza kwe-compressor, vula umnyango, vumela izinga lokushisa lomtapo wolwazi likhuphuke, ukuze lincibilike ngokuzenzakalelayo ungqimba lweqhwa, bese uqala kabusha i-compressor.
②Ukuhlanzwa kweqhwa. Ngemva kokukhipha izimpahla endaweni yokugcina impahla, hlanza ngqo ubuso bepayipi lomugqa we-evaporator ngamanzi ompompi ashisayo aphezulu ukuze ungqimba lweqhwa luncibilike noma luwe. Ngaphezu kokuthi iqhwa likhulu kakhulu kuzoholela ekutheni umphumela wokudlulisa ukushisa kwe-evaporator awulungile, ukubukeka kwe-evaporator ngenxa yokungahlanzwa okwesikhashana kanye nokuqongelela kothuli kukhulu kakhulu, ukusebenza kahle kokudlulisa ukushisa nakho kuzoncishiswa kakhulu.
Umphumela wokudlulisa ukushisa uyancipha (isithwathwa sangaphandle se-evaporator sijiyile kakhulu noma sinqwabelana kakhulu ngothuli)
Ukushisa kanye nomphumela wokushisa akubi, umsebenzi wokushisa obi ngoba ukujiya kwengqimba yokushisa yepayipi, udonga lokushisa lwendlu yokugcina impahla, njll. akwanele. Kubangelwa kakhulu ukukhetha okungafanele ukujiya kwengqimba yokushisa lapho kuklanywa noma ikhwalithi ephansi yezinto zokushisa lapho kwakhiwa.
Ngaphezu kwalokho, inqubo yokwakha nokusebenzisa, umsebenzi wokuvikela umswakama wokuvikela umswakama wezinto zokuvimbela umswakama ungonakala okuholela ekumswakamani kwengqimba yokuvimbela umswakama, ukuguqulwa, ngisho nokubola, amandla ayo okuvimbela umswakama kanye nokuvimbela umswakama ayancipha, umtapo wolwazi ngokumelene nokulahlekelwa yimakhaza uyanda, ukwehla kwezinga lokushisa lomtapo wolwazi kwehla kakhulu.
Esinye isizathu esibalulekile sokulahlekelwa umkhuhlane umsebenzi wokuvala ompofu wendlu yokugcina impahla, kunomoya oshisayo owengeziwe ovela emoyeni ovuza ungene endlini yokugcina impahla. Ngokuvamile, uma uphawu lomnyango noma indawo yokugcina ebandayo lushisa udonga ngesikhathi sokuguquka komswakama, kusho ukuthi uphawu aluqinile.
Ngaphezu kwalokho, ukuvulwa nokuvalwa njalo komnyango noma abantu abaningi abangena ndawonye endlini yokugcina impahla kuzokwandisa ukulahleka kwendawo yokugcina ebandayo. Kufanele uzame ukuvimbela ukuvula umnyango ukuze uvimbele umoya oshisayo omningi ungene endlini yokugcina impahla. Yiqiniso, indlu yokugcina impahla ingena endlini yokugcina impahla njalo noma ibe nkulu kakhulu, umthwalo wokushisa uyanda kakhulu, ukuze uphole uze ufike ezingeni lokushisa elicacisiwe ngokuvamile kuthatha isikhathi eside.
Okubangela ukulahlekelwa okukhulu kokubanda (indawo yokugcina ebanda ngenxa yokungasebenzi kahle kokuvikela noma ukuvala)
Indandatho ye-cylinder liner kanye ne-piston nezinye izingxenye ngenxa yokuguga okukhulu, i-compressor ngenxa yokusebenza kwesikhashana. Njengoba ivuliwe kakhulu, umsebenzi wokuvala uzoncishiswa ngokufanayo, i-coefficient yokulethwa komoya kwe-compressor nayo incishisiwe, umthamo wokuqandisa uzoncishiswa. Uma umthamo wokupholisa ungaphansi komthwalo wokushisa wendlu yokugcina impahla, kuzoholela ekwehleni kancane kwezinga lokushisa lendlu yokugcina impahla. Kungabonakala ngokubona ingcindezi yokumunca nokukhipha i-compressor cishe inquma umthamo wokuqandisa we-compressor. Uma umthamo wokupholisa we-compressor wehla, indlela evamile ukufaka esikhundleni sendandatho yesilinda se-compressor kanye ne-piston, uma ukushintshwa kusasebenza, ezinye izici kufanele zicatshangelwe, futhi ngisho nokudiliza umshini ukuze kuhlolwe, ukuze kukhishwe izici zamaphutha.
