Amandla okupholisa awakwazi ukuhlangabezana nezidingo zomthwalo wendlu yokugcina impahla
(ukusebenza kahle kwe-compressor okuphansi)
Kunezizathu ezimbili eziyinhloko zokuntuleka kokujikeleza kwegazi okuqandisiwe.
Okokuqala, ishaja yesiqandisi ayanele, futhi kudingeka inani elanele lesiqandisi ngalesi sikhathi;
Esinye isizathu ukuthi kunokuvuza okuningi kwe-refrigerant ohlelweni. Ukuze ubhekane nalesi simo, kufanele uqale uthole indawo yokuvuza, ugxile ekuhloleni ukuxhumana kwepayipi ngalinye kanye ne-valve, bese ugcwalisa inani elanele le-refrigerant ngemva kokulungisa izingxenye ezivuzayo.
Ukuntuleka kwamandla okupholisa
(Inani elingenele le-refrigerant ohlelweni)
Inani elanele le-refrigerant ohlelweni lithinta ngqo ukugeleza kwe-refrigerant ku-evaporator. Uma ukuvulwa kwe-valve yokwandisa kukhulu kakhulu, i-valve yokwandisa ayilungiswanga kahle noma ivinjiwe. Izinga lokugeleza kwe-refrigerant likhulu kakhulu, ingcindezi yokuhwamuka kanye nezinga lokushisa lokuhwamuka nakho kuyakhuphuka, futhi izinga lokwehla kwezinga lokushisa lendlu yokugcina impahla lizoncipha; ngesikhathi esifanayo, lapho i-valve yokwandisa ivulwa incane kakhulu noma ivinjiwe, izinga lokugeleza kwe-refrigerant nalo liyancipha, futhi amandla okupholisa esistimu nawo ayakhuphuka. Ukwehla kwezinga lokushisa lendlu yokugcina impahla nakho kuzoncipha. Ngokuvamile, kungahlulelwa ukuthi izinga lokugeleza kwe-refrigerant le-valve yokwandisa lifanelekile yini ngokubheka ingcindezi yokuhwamuka, izinga lokushisa lokuhwamuka kanye nesimo se-frosting sepayipi yokumunca. Ukuvaleka kwe-valve yokwandisa kuyisici esibalulekile esithinta ukugeleza kwe-refrigerant. Izimbangela eziyinhloko zokuvaleka kwe-valve yokwandisa ukuvaleka kweqhwa kanye nokuvaleka okungcolile. Ukuvaleka kweqhwa kungenxa yokuthi umphumela wokomisa we-dryer awulungile, futhi i-refrigerant iqukethe umswakama. Uma igeleza nge-valve yokwandisa, izinga lokushisa lehla ngaphansi kuka-0 °C, bese umswakama osesiqandisini uqina ube yiqhwa bese uvimba imbobo ye-throttle valve; ukuvimba okungcolile kungenxa yokuthi Kunokungcola okuningi okuqongelelwe esikrinini sesihlungi endaweni yokungena ye-valve yokwandisa, futhi i-refrigerant ayibushelelezi futhi ayibushelelezi, okubangela ukuvaleka.
Ukugeleza kwesiqandisi kukhulu kakhulu noma kuncane kakhulu
(ukulungiswa okungafanele noma ukuvaleka kwevalvu yokwandisa)
I-coefficient yayo yokudlulisa ukushisa izoncipha, uma uwoyela obandayo usufakwe ngaphakathi nangaphandle kwepayipi lokudlulisa ukushisa le-evaporator. Ngokufanayo, uma kunomoya omningi epayipini lokudlulisa ukushisa, indawo yokushintshanisa ukushisa ye-evaporator izoncipha, ukusebenza kahle kokudlulisa ukushisa nakho kuzoncipha kakhulu, futhi izinga lokwehla kwezinga lokushisa lendlu yokugcina impahla lizoncipha. Ngakho-ke, ekusebenzeni nasekugcinweni kwansuku zonke, kufanele kuqashelwe ukususwa ngesikhathi kwamabala kawoyela ngaphakathi nangaphandle kwepayipi lokudlulisa ukushisa le-evaporator kanye nokukhishwa komoya ku-evaporator ukuze kuthuthukiswe ukusebenza kahle kokudlulisa ukushisa kwe-evaporator.
Umphumela wokudlulisa ukushisa oncishisiwe
(Kukhona uwoyela womoya noma wokuqandisa owengeziwe ku-evaporator)
Lokhu kungenxa yokuthi ungqimba lwesithwathwa olungaphandle kwe-evaporator lukhulu kakhulu noma uthuli lukhulu kakhulu. Ngenxa yokuthi izinga lokushisa langaphandle le-evaporator endaweni yokugcina ebandayo liphansi kakhulu kune-0 ℃, esinye isizathu esibalulekile sokwehla kancane kwezinga lokushisa lokugcina ukusebenza kahle kokudlulisa ukushisa kwe-evaporator. Umswakama wendawo yokugcina impahla uphakeme kakhulu, futhi umswakama emoyeni kulula kakhulu ukuwuqandisa noma ngisho nokuwuqandisa ebusweni be-evaporator, okuthinta umphumela wokudlulisa ukushisa kwe-evaporator. Ukuze kuvinjelwe ungqimba lwangaphandle lwesithwathwa se-evaporator ukuthi lube lukhulu kakhulu, ludinga ukuncibilikiswa njalo.
Nazi izindlela ezimbili ezilula zokuncibilikisa:
① Misa ukuze uncibilikise. Okusho ukuthi, yeka ukusebenza kwe-compressor, vula umnyango wendlu yokugcina impahla, vumela izinga lokushisa lendlu yokugcina impahla likhuphuke, bese uqala kabusha i-compressor ngemva kokuba ungqimba lwesithwathwa luncibilika ngokuzenzakalelayo.
②Ukhilimu we-Chong. Ngemva kokukhipha izimpahla endaweni yokugcina impahla, hlanza ngqo ubuso bepayipi le-evaporator ngamanzi ompompi ngokushisa okuphezulu ukuze uncibilikise noma uwe ungqimba lweqhwa. Ngaphezu komphumela omubi wokudlulisa ukushisa kwe-evaporator ngenxa yeqhwa elijiyile, ubuso be-evaporator bukhulu kakhulu ngenxa yokungcola kwesikhashana, futhi ukusebenza kahle kokudlulisa ukushisa kwayo kuzoncishiswa kakhulu.
Umphumela wokudlulisa ukushisa oncishisiwe
(Ubuso be-evaporator buqandisiwe kakhulu noma bunothuli oluningi kakhulu)
Imiphumela emibi yokuvikela ukushisa kanye nokuvikela ukushisa, kanye nokusebenza kabi kokuvikela ukushisa kungenxa yobukhulu obunganele bezingqimba zokuvikela ukushisa ezifana namapayipi kanye nezindonga zokuvikela ukushisa zendlu yokugcina impahla. Lokhu kubangelwa kakhulu ukukhetha okungafanele kobukhulu bezingqimba zokuvikela ukushisa ngesikhathi sokuklama noma ikhwalithi ephansi yezinto zokuvikela ukushisa ngesikhathi sokwakha.
Ngaphezu kwalokho, ngesikhathi sokwakhiwa nokusetshenziswa, ukuvikela ukushisa kanye nomsebenzi wokuvikela umswakama wezinto zokuvikela ukushisa kungase konakale, okuholela ekutheni ungqimba lokuvikela ukushisa lube manzi, lukhubazeke, noma luguguleke.
Esinye isizathu esibalulekile sokulahlekelwa okukhulu kokupholisa ukusebenza kahle kokuvala kwendlu yokugcina impahla, futhi umoya oshisayo omningi ungena endlini yokugcina impahla ngenxa yokuvuza. Ngokuvamile, uma kukhona ukujiya esivalweni somnyango wendlu yokugcina impahla noma esivalweni sodonga lokuvikela indawo yokugcina izinto ezibandayo, kusho ukuthi isivalo asiqinile.
Ngaphezu kwalokho, ukuvulwa nokuvalwa njalo komnyango wendlu yokugcina impahla noma abantu abaningi abangena ndawonye endlini yokugcina impahla nakho kuzokwandisa ukulahleka kwamandla okupholisa endlini yokugcina impahla. Umnyango wendlu yokugcina impahla kufanele uvinjelwe ekuvulekeni ngangokunokwenzeka ukuze kuvinjelwe umoya oshisayo omkhulu ukuthi ungangeni endlini yokugcina impahla. Vele, lapho indlu yokugcina impahla ivame ukugcwala noma isitokwe sikhulu kakhulu, umthwalo wokushisa uyanda kakhulu, futhi ngokuvamile kuthatha isikhathi eside ukupholisa kuze kufike ekushiseni okubekiwe.
kuholela ekulahlekelweni okukhulu kokupholisa
(indawo yokugcina ebanda ngenxa yokushisa okungekuhle noma ukusebenza kahle kokuvala)
Izingxenye ezifana nama-cylinder liner nama-piston rings zigugile kakhulu, futhi i-compressor isebenza okwesikhashana. Lapho imvume efanayo ikhula, ukusebenza kokuvala kuzoncipha ngokufanele, i-coefficient yokudlulisa igesi ye-compressor nayo izoncipha, futhi amandla okupholisa azoncipha. Lapho amandla okupholisa engaphansi komthwalo wokushisa wendlu yokugcina impahla, izinga lokushisa lendlu yokugcina impahla lizoncipha kancane. Amandla okupholisa e-compressor anganqunywa ngokubheka ukucindezela kokumunca nokukhipha kwe-compressor. Uma amandla okupholisa e-compressor encipha, indlela evame ukusetshenziswa ukufaka esikhundleni se-cylinder liner kanye ne-piston ring ye-compressor. Uma ukufaka esikhundleni kungasebenzi, ezinye izici kufanele zicatshangelwe, noma ngisho nokudiliza nokuhlola ukuze kususwe izici zamaphutha.
