I-Thermal Expension Valve, ishubhu le-capillary, i-valve yokwanda ngogesi, amadivayisi amathathu abalulekile wokuphonsa

Indlela yokuphonsa ngenye yezinto ezibalulekile kudivayisi yefriji. Umsebenzi wayo ukunciphisa uketshezi olugcwele (noma uketshezi oluhlanganisiwe) ngaphansi kwengcindezi ethobisayo ku-condenser noma isitholi esiwuketshezi ekushiseni kokuhwamuka nokuhwamuka kokuhwamuka ngemuva kokuphola. Ngokokuguqulwa komthwalo, ukugeleza kwesiqandisi esingena e-Evaporator kuyalungiswa. Amadivayisi ajwayelekile asetshenziswa ngokuthambisa afaka amashubhu we-capillary, ama-valves wokunwebeka ashisayo, nama-valves wokuntanta.

Uma inani le-ketshezi elihlinzekwa yi-veraplism meshini ku-evaporator likhulu kakhulu uma liqhathaniswa nomthwalo we-evaporator, ingxenye ye-degrindant ketshezi izongena kwi-compressor kanye nesiqandisi esimanzi noma izingozi zesando.

Ngokuphambene nalokho, uma inani lokuhlinzekwa koketshezi lincane kakhulu uma liqhathaniswa nomthwalo wokushisa we-evaporator, ingxenye yendawo yokushintshana kokushisa kwe-evaporator ngeke ikwazi ukusebenza ngokuphelele, futhi ngisho nengcindezi yokuhwamuka izoncishiswa; Futhi amandla apholile ohlelo azoncishiswa, i-coefficient epholile izoncishiswa, futhi i-compressor lokutshala liyakhuphuka, okuthinta ukuthambisa okujwayelekile kwe-compressor.

Lapho uketshezi lwefriji ludlula emgodini omncane, ingxenye yengcindezi ye-static iguqulwa ibe ngengcindezi enamandla, futhi isilinganiso sokugeleza sikhuphuka kakhulu, futhi i-fluid iyaphazamisa, ukuze umfutho we-tusha uyakhuphuka, ukuze umfutho we-static uyancipha, ukuze umfutho we-static unciphise ukunciphisa ingcindezi nokulawula ukugeleza.

I-Throttling ingenye yezinqubo ezine eziphambili ezibaluleke kakhulu kumjikelezo wefriji we-compressional umjikelezo.

Indlela yokunciphisa inemisebenzi emibili:

Eyokuqala ukuklebhula futhi icindezele i-high-liquid eqandisi ephumayo ephuma kumfutho we-flounser

Okwesibili ukulungisa inani le-Defrignant Liquid efaka i-Evaporator ngokuya ngezinguquko zomthwalo wesistimu.

1. I-Thermal Expension Valve

I-Thermal Expension Valve isetshenziswa kabanzi kuhlelo Lwesiqandisi seFreeon. Ngokusebenza komshini wokuzwakala kwezinga lokushisa, kuguquka ngokuzenzakalelayo ngokushintsha kwezinga lokushisa kwesiqandisi esigabeni se-evelet of the Evaporator ukufeza inhloso yokulungisa isiqandisi esiqandwayo.

Ama-valves wokunwebeka amaningi ashisayo ane-superheat yawo ebekwe ngo-5 kuye ku-6 ° C ngaphambi kokushiya ifektri. Ukwakheka kwe-valve kuqinisekisa ukuthi lapho i-superheat inyuka ngomunye 2 ° C, i-valve isesimweni esivulekile ngokuphelele. Lapho i-superheat icishe ibe ngu-2 ° C, i-valve yokwanda izovalwa. Intwasahlobo yokulungiswa yokulawula i-superheat, uhla lokulungiswa lungu-3 ~ 6 ℃.

Ngokuvamile, kuphakama izinga lokuphakama kwe-superheat elibekwe yi-thermal expansion valve, ngoba ukwanda umthamo wokufudumala wokushisa we-evaporator, ngoba ukwandisa izinga le-superheat kuzothatha ingxenye enkulu yendawo yokudlulisa ukushisa emsileni we-evaporator, ukuze umusi ogcwele ugcwele ungalawulwa lapha. Ihlala engxenyeni yendawo yokudlulisa ukushisa yomkhathi, ukuze indawo yefriji yefriji yefriji kanye nokutholwa kokushisa kuncishiswe kakhulu, okusho ukuthi, ingabe yinto ye-evaporator ayisetshenziswa ngokuphelele.

Kodwa-ke, uma izinga le-Superheat liphansi kakhulu, uketshezi oluqandisayo lungalethwa ku-compressor, okuholela ekutheni kwesando esingesihle sesando se-liquid. Ngakho-ke, ukulawulwa kwe-superheat kufanele kufanelekile ukuqinisekisa ukuthi isiqandisi esanele singena ku-vaporator ngenkathi sivimbela ukuqanda kwesiqandisi esingu-compressor.

I-valve ye-thermal yokunwebeka ihlanganiswa nomzimba we-valve, iphakethe lokushisa lokushisa kanye ne-capillary tube. Kunezinhlobo ezimbili ze-Thermal Expension Valve: Uhlobo lwangaphakathi lwangaphakathi nohlobo lwangaphandle lwangaphandle ngokuya ngezindlela ezahlukahlukene ze-diaphragm.

I-valve ye-thermal ebanzi enokulinganisa

I-valve ye-thermal enokulinganisa enokulinganisela yakhiwa ngomzimba we-valve, i-push induku, isihlalo se-valve, inaliti ye-valve, isibani sokushisa, ishubhu lokushisa, i-tube yokuzwakala.

I-valve ye-thermal enokulinganisa yangaphandle

Umehluko phakathi kwe-valve yebhalansi yangaphandle yohlobo lokunwebeka kanye nohlobo lwangaphakathi lwebhalansi ekwakhiweni nasekufakweni ukuthi isikhala esingaphansi kwe-valve valve diaphragm asixhunyiwe kwi-valve extet, kepha ipayipi elincane elilinganiselwe lisetshenziselwa ukuxhumana nokuphuma kwe-evaporator. Ngale ndlela, ingcindezi esiqandisi esebenza ngaphansi kwe-diaphragm ayisona i-po endaweni yokungena ngemuva ngemuva kokuphonsa, kepha i-PC PC lapho uphuma khona umhlaka. Lapho amandla e-diaphragm alinganiselwe, yi-PG = PC + PW. Izinga lokuvula le-valve alithintwa ukumelana nokugeleza kwekhoyili ye-evaporator, ngaleyo ndlela linqobe ukushiyeka kohlobo lwangaphakathi lwebhalansi. Uhlobo lwangaphandle lwangaphandle lusetshenziswa kakhulu ezikhathini lapho ukumelana kwamakhoyili ka-vaporator kukhulu.

Imvamisa, iziqu ze-Steam Superheat degree lapho i-valve yokwanda ivaliwe ibizwa nge-superheat evaliwe, futhi iziqu ze-superheat ezivalekile nazo zilingana neziqu ze-superheat ezivulekile lapho i-valve hole iqala ukuvula. Ukuvalwa kwe-superheat kuhlobene nokulayisha kabusha kwentwasahlobo, okungashintshwa yi-lever yokulungiswa.

Isikhundla esiphezulu lapho intwasahlobo ilungiswa esimweni esiphakeme ibizwa ngokuthi yi-Superheat evaliwe; Ngokuphambene nalokho, i-superheat lapho intwasahlobo ilungiswa ku-tietive kubizwa ngokuthi i-superheat evalekile. Ngokuvamile, izinga eliphansi elivaliwe le-superheat le-valve elinwetshiwe alikho ngaphezu kwe-2 ℃, kanye neziqu ze-Superheat ezivalekile kakhulu azinazo ngaphansi kwe-8 ℃.

Ukuze uthole i-valve yangaphakathi yokunwetshwa kwe-thermal themal Uma ukumelana kwe-evaporator kukhulu, kuzoba nokulahleka okukhulu kokugqwala lapho esiqandisi esivele singena kwezinye izibungu, okuzothinta kakhulu i-valve ye-thermal. Ukusebenza kokusebenza kwe-evaporator kukhuphuka, okuholela ekwandeni kweziqu eziphakemeyo endaweni yokuphuma e-Evaporator, kanye nokusetshenziswa okungenangqondo kwendawo yokudlulisa ukushisa komkhathi.

Ama-valves entengo alinganiselayo alinganiselayo, ukucindezela okusebenzayo ngaphansi kwe-diaphragm yingcindezi yokuphuma komthengisi, hhayi ingcindezi yokuhwamuka, futhi isimo siyathuthukiswa.

2. I-Capillary

I-capillary iyithuluzi elilula kakhulu elishisayo. I-capillary iyi-tube emincane kakhulu yethusi ngobude obucacisiwe, futhi ububanzi bawo bangaphakathi bungu-0,5 kuya ku-2 mm.

Izici ze-capillary njengedivayisi yokuphonsa

(1) I-capillary idonswa kusuka kushubhu elibomvu lethusi, elilungele ukukhiqiza futhi lishibhile;

(2) Azikho izingxenye ezinyakazayo, futhi akulula ukudala ukwehluleka nokuvuza;

(3) Inezimpawu zokuzinxephezela,

(4) Ngemuva kokuthi i-compressor ye-compressor iyeke ukugijima, ingcindezi ohlangothini oluphakeme kakhulu futhi ingcindezi ohlangothini lwengcindezi ephansi ohlelweni lweqandi lungalinganiswa ngokushesha. Lapho kuqala ukugijima futhi, imoto ye-compressor yefriji iqala.

I-3. I-electronic expension valve

I-Valve Valve ye-elekthronikhi ngohlobo lwejubane, olusetshenziswa ku-inverter air condmoreder ehlakaniphile. Izinzuzo zeValve ye-elekthronikhi ye-elekthronikhi yilezi: uhla olukhulu lokuguqulwa kwe-flow; ukunemba okulawula okuphezulu; Ilungele ukulawulwa okukhaliphile; Ilungele izinguquko ezisheshayo ekuhambeni okuphezulu kokuqagelwa.

Izinzuzo zama-valve enwebhu kagesi

Uhla olukhulu lokuguquguquka;

Ukuqonda okuphezulu okuphezulu;

Ilungele ukulawulwa okukhaliphile;

Ingasetshenziswa ezinguquko ezisheshayo ekugelezeni esiqandisini ngokusebenza okuphezulu.

Ukuvulwa kwe-electronic expension valve kungashintshwa ngejubane le-compressor, ukuze inani lesiqandisi lilethwe yisamba esithathwe inani loketshezi olunikezwe yi-valve, ukuze amandla ohlelo oluphelele akhuliswe futhi alawulwe kahle wohlelo lwe-air conditioning kanye nohlelo lokuqapha.

Ukusetshenziswa kwe-valve ye-elekthronikhi ye-elekthronikhi kungathuthukisa ukusebenza kahle kwamandla kwe-inverter compressular, qaphela ukulungiswa kokushisa okusheshayo, futhi kuthuthukise isilinganiso sokusebenza kwamandla kwesizini sohlelo. Okwezimo ze-inverter eziphakeme zomoya, ama-valve ekhuliswe ngogesi kufanele asetshenziswe njengezakhi ezisheshayo.

Ukwakheka kwe-electronic expansion valve valve kuqukethe izingxenye ezintathu: ukutholwa, ukulawula kanye nokubulawa. Ngokwendlela yokushayela, ingahlukaniswa ngohlobo lwe-electromagnetic nohlobo lukagesi. Uhlobo lukagesi luhlukaniswe ngohlobo olusebenzayo nohlobo lokukhohlisa. I-Stepping motor ene-valve inaliti ngohlobo olusebenzayo, kanye nemoto yokuhamba nge-valve ngenaliti nge-gear set redwer luwuhlobo lokukhohlisa.
