Kungani i-compressor yokugcina iqhwa iqhwa?

I-1-Imishini yokugcina ebandayo: Isithwathwa esikwi-compressor return air port sibonisa ukuthi izinga lokushisa lomoya lokubuyisela i-compressor liphansi kakhulu. Ngakho-ke yini ezobangela ukuthi izinga lokushisa lomoya le-compressor libe liphansi kakhulu?

Kuyaziwa ukuthi uma umthamo nokucindezela kwekhwalithi efanayo yesiqandisi kuguqulwa, izinga lokushisa lizoba nokusebenza okuhlukile. Okungukuthi, uma i-refrigerant ye-liquid ithatha ukushisa okwengeziwe, ukucindezela, izinga lokushisa kanye nevolumu yekhwalithi efanayo yesiqandisi kuyoba phezulu. Uma ukumuncwa kokushisa kuncane, ukucindezela, izinga lokushisa kanye nevolumu kuzoba phansi.

Okusho ukuthi, uma izinga lokushisa lomoya elibuyisela i-compressor liphansi, ngokuvamile lizobonisa ukucindezela komoya okubuyayo okuphansi kanye nomthamo omkhulu wesiqandisi wevolumu efanayo. Isizathu esiyinhloko salesi simo ukuthi isiqandisi esigeleza ku-evaporator asikwazi ukumunca ukushisa okudingekayo ukuze sandise ukucindezela okunqunywe kusengaphambili kanye nenani lokushisa, okuholela ekubuyiseleni okuphansi kwezinga lokushisa lomoya, ukucindezela kanye namanani evolumu.

Kunezizathu ezimbili zale nkinga:

1. Ukunikezwa kwesiqandisi se-throttle valve liquid sijwayelekile, kodwa i-evaporator ayikwazi ukumunca ukushisa ngokujwayelekile ukuze inikeze ukunwetshwa kwesiqandisi.

2. I-evaporator ibamba ukushisa ngokujwayelekile, kodwa i-throttle valve refrigerant supply ikhulu kakhulu, okungukuthi, ukugeleza kwesiqandisi kuningi kakhulu. Sivame ukuyiqonda njenge-fluorine eningi, okungukuthi, i-fluorine eningi izophinde ibangele ukucindezela okuphansi.

2- Imishini yokugcina ebandayo: Isithwathwa se-compressor esibuyisela umoya ngenxa ye-fluorine enganele

1. Ngenxa yezinga lokugeleza eliphansi kakhulu lesiqandisi, isiqandisi sizoqala ukwanda esikhaleni sokuqala esinwebekayo ngemva kokugeleza siphuma engxenyeni engemuva ye-throttle valve. Iningi lesithwathwa ekhanda le-liquid distributor ekupheleni kwe-valve yokwandisa ngokuvamile libangelwa ukuntuleka kwe-fluorine noma ukugeleza okwanele kwe-valve yokwandisa. Ukunwetshwa kwesiqandisi okuncane kakhulu ngeke kusebenzise yonke indawo ye-evaporator, futhi izinga lokushisa eliphansi kuphela elizokwakhiwa endaweni ku-evaporator. Ezinye izindawo zizokhula ngokushesha ngenxa yenani elincane lesiqandisi, okubangela izinga lokushisa lasendaweni ukuba libe phansi kakhulu, okuholela esithwathwaneni esishunqayo.

Ngemuva kwesithwathwa sendawo, ngenxa yokwakhiwa kwesendlalelo sokufakwa kwe-insulation ebusweni be-evaporator kanye nokushintshaniswa kokushisa okuphansi kule ndawo, ukunwetshwa kwesiqandisi kuzodluliselwa kwezinye izindawo, futhi yonke i-evaporator izoba yiqhwa noma iqhwa. I-evaporator yonke izokwakha isendlalelo sokuhlukanisa, ngakho-ke ukunwetshwa kuzosakazeka epayipini lokubuyisela i-compressor, okubangela ukuthi i-compressor ibuyisele umoya kusithwathwa.

2. Ngenxa yenani elincane lesiqandisi, ingcindezi yokuhwamuka kwe-evaporator iphansi, okuholela ekushiseni okuphansi kwe-evaporation, okuzokwenza kancane kancane ukuthi i-evaporator ihlanganise futhi yakhe isendlalelo sokumisa, futhi iphuzu lokunweba lizodluliselwa emoyeni wokubuyisela i-compressor, okubangela ukuthi i-compressor ibuyisele umoya ku-frost. Womabili amaphuzu angenhla azobonisa ukuthi i-evaporator iqhwa ngaphambi kokuba umoya wokubuyisela i-compressor ube nesithwathwa.
Eqinisweni, ezimweni eziningi, ngenxa ye-frosting phenomenon, udinga kuphela ukulungisa i-valve ye-bypass yegesi eshisayo. Indlela eqondile ukuvula isembozo esingemuva esingemuva se-valve yegesi eshisayo, bese usebenzisa iwrench engu-No. 8 hexagonal ukuze uguqule inadi elilungisayo libe ngaphakathi ngokwewashi. Inqubo yokulungisa akufanele isheshe kakhulu. Ngokuvamile, izomiswa ngemva kokuphendula uhhafu wombuthano. Vumela isistimu ukuthi isebenze isikhashana ukuze ibone isimo sesithwathwa ngaphambi kokunquma ukuthi izoqhubeka yini nokulungisa. Linda kuze kube yilapho ukusebenza kuzinzile futhi ukwenzeka kwesithwathwa se-compressor kuyanyamalala ngaphambi kokuqinisa isembozo sokugcina.
Kumamodeli angaphansi kwama-cubic metres ayi-15, njengoba ingekho i-valve yokudlula igesi eshisayo, uma isimo seqhwa sibucayi, ingcindezi yokuqala ye-condensing fan pressure switch ingakhuliswa ngokufanelekile. Indlela eqondile iwukuba uqale uthole inkinobho yokucindezela, ukhiphe ucezu oluncane lwentongomane yokulungisa i-pressure switch, bese usebenzisa isikrudrayiva esiphambanayo ukuze uzungezise ngokwewashi. Ukulungiswa konke nakho kudinga ukwenziwa kancane. Yilungise uhhafu wombuthano ukuze ubone isimo ngaphambi kokuthatha isinqumo sokuthi uzosilungisa yini.
