Indima yezinto eziphambili zesomisi esiqandisiweyo
1. Icompressor yefriji
Iicompressor zefriji yintliziyo yenkqubo yefriji, kwaye uninzi lweecompressor namhlanje zisebenzisa i-hermetic reciprocating compressors.Ukuphakamisa i-refrigerant ukusuka kwi-low to high pressure kunye nokujikeleza i-refrigerant ngokuqhubekayo, inkqubo ngokuqhubekayo ikhupha ukushisa kwangaphakathi kwindawo engaphezulu kweqondo lokushisa.
2. Icondenser
Umsebenzi we-condenser kukupholisa uxinzelelo oluphezulu, umphunga ogqithisiweyo ogqithisiweyo okhutshwe yi-compressor yefriji kwi-refrigerant yamanzi, kwaye ubushushu bayo buthathwa ngamanzi apholisayo.Oku kuvumela inkqubo yefriji ukuba iqhubeke ngokuqhubekayo.
3. Umphunga
I-evaporator yeyona nto iphambili yokutshintshiselana ngobushushu kwisixhobo esomisa isibandisi, kwaye umoya ocinezelweyo upholiswa ngenkani kwi-evaporator, kwaye uninzi lomphunga wamanzi uyapholiswa kwaye ujijelwe kumanzi alulwelo kwaye ukhutshwe ngaphandle komatshini, ukuze umoya ocinezelweyo womiswe. .Ulwelo olusezantsi loxinzelelo lwefriji luba ngumphunga ophantsi woxinzelelo ngexesha lotshintsho lwesigaba kwi-evaporator, lufunxa ubushushu obujikelezileyo ngexesha lotshintsho lwesigaba, ngaloo ndlela lupholisa umoya oxinanisiweyo.
4. Ivalve yokwandisa iThermostatic (icapillari)
I-valve yokwandisa i-thermostatic (i-capillary) yindlela yokugubha yenkqubo yefriji.Kwi-dryer dryer, ukunikezelwa kwe-evaporator refrigerant kunye nomlawuli wayo ufezekiswa nge-throttling mechanism.I-throttling mechanism ivumela ifriji ukuba ingene kwi-evaporator ukusuka kubushushu obuphezulu kunye noxinzelelo oluphezulu.
5. Umtshintshi wobushushu
Uninzi lwezikhenkcezisi zefriji zinesixhobo sokutshintshisa ubushushu, esitshintsha ubushushu phakathi komoya nomoya, ngokuqhelekileyo i-tubular heat exchanger (eyaziwa ngokuba yiqokobhe kunye ne-tube exchanger heat exchanger).Umsebenzi ophambili wesixhobo sokutshintshisa ubushushu kwisixhobo esomileyo “kukubuyisela” amandla okupholisa athwalwa ngumoya ocinezelweyo emva kokuba upholiswe ngumphunga, kwaye usebenzise le nxalenye yesakhono sokupholisa ukupholisa umoya ocinezelweyo kubushushu obuphezulu obuthwele i-evaporator. umthamo omkhulu womphunga wamanzi (oko kukuthi, umoya ocinezelweyo ohluthisiweyo okhutshwa kwicompressor yomoya, upholiswe sisipholile esingasemva secompressor yomoya, emva koko yahlulwe ngumoya kunye namanzi angaphezulu kwama-40 °C), ngaloo ndlela kuncitshiswa umthwalo wokufudumeza ifriji kunye nenkqubo yokomisa kunye nokufezekisa injongo yokonga amandla.Kwelinye icala, iqondo lobushushu lobushushu obuphantsi bomoya ocinezelekileyo kwindawo yokutshintsha ubushushu bubuyiselwa, ukwenzela ukuba udonga lwangaphandle lombhobho ohambisa umoya ocinezelekileyo lungabangeli “condensation” isenzeko ngenxa yobushushu obungaphantsi kobushushu obuphantsi kwendawo.Ukongezelela, emva kokunyuka kweqondo lokushisa lomoya oxinyiweyo, umswakama ohambelana nomoya oxinyiweyo emva kokumisa uyancitshiswa (ngokuqhelekileyo ungaphantsi kwe-20%), enenzuzo ukukhusela i-rust yentsimbi.Abanye abasebenzisi (umzekelo ngezityalo zokwahlula umoya) badinga umoya oxinanisiweyo onobumanzi obuphantsi kunye nobushushu obuphantsi, ngoko ke isixhobo sokomisa ifriji asisaxhotyiswanga sisixhobo sokutshintsha ubushushu.Ekubeni umtshintshi wokushisa ungafakwanga, umoya obandayo awukwazi ukuphinda usetyenziswe, kwaye umthwalo wokushisa we-evaporator uya kwanda kakhulu.Kule meko, kungekhona nje kuphela amandla e-compressor yefriji kufuneka anyuswe ukuhlawulela amandla, kodwa kunye nezinye iinqununu zenkqubo yonke yefriji (i-evaporator, i-condenser kunye ne-throttling components) kufuneka inyuswe ngokufanelekileyo.Ngokombono wokubuyisela amandla, sihlala sithemba ukuba ukuphakama kweqondo lokushisa kwefriji yefriji, kungcono (iqondo lokushisa eliphezulu, elibonisa ukubuyiswa kwamandla amaninzi), kwaye kungcono ukuba akukho mahluko obushushu phakathi kokungena kunye nokuphuma.Kodwa eneneni, akunakwenzeka ukufezekisa oku, xa iqondo lokushisa lokungenisa umoya lingaphantsi kwe-45 °C, akuqhelekanga ukuba amaqondo okushisa angenayo kunye nokuphuma kwesomisi sefriji ahluke ngaphezu kwe-15 °C.
UCwangciso loMoya oQinisekileyo
Umoya oxinisiweyo→ izihluzi ezinoomatshini→ izihluzi zobushushu (ukukhululwa kobushushu), →umphunga→ izahluli zolwelo lwerhasi→ izahluli zobushushu (ukufunxa ubushushu), → izihluzi eziphuma ngoomatshini→ iitanki zokugcina igesi
Ugcino nokuhlola: gcina iqondo lombethe lobushushu besixhobo sokukhenkcisa esiqandisini ngaphezu kweqanda.
Ukunciphisa ubushushu bomoya obucinezelekileyo, ubushushu befriji ephuphumayo kufuneka bube phantsi kakhulu.Xa isikhenkcezisi sipholisa umoya ocinezelweyo, kukho umaleko wefilim-efana ne-condensate kumphezulu we-fin ye-evaporator liner, ukuba ubushushu bomphezulu we-fin bungaphantsi kwe-zero ngenxa yokuncipha kobushushu bomphunga, umphezulu. I-condensate inokuba ngumkhenkce, ngeli xesha:
A. Ngenxa yokuncanyathiselwa komgangatho womkhenkce one-conductivity encinci ye-thermal kumphezulu we-evaporator yangaphakathi yesinyi, ukutshintshiselana kobushushu kuncitshiswe kakhulu, umoya ocinezelweyo awukwazi ukupholiswa ngokupheleleyo, kwaye ngenxa yokuba ukunyanzeliswa kobushushu obungonelanga, ubushushu bokufudumala kwefriji bunokuncitshiswa ngakumbi, kwaye umphumo womjikelezo onjalo ngokuqinisekileyo uya kuzisa iziphumo ezibi kakhulu kwinkqubo yefriji (efana "noxinzelelo lwamanzi");
B. Ngenxa yesithuba esincinci phakathi kwee-fins kwi-evaporator, emva kokuba i-fins iqhwa, indawo yokujikeleza komoya ocinezelweyo iya kuncitshiswa, kwaye kunye nendlela yomoya iya kuvalwa kwiimeko ezinzima, oko kukuthi, "i-ice blockage";Ngamafutshane, iqondo lobushushu lendawo yokucinezela umbethe kufuneka libe ngaphezulu kwe-0 °C, ukuze kuthintelwe iqondo lombethe ekubeni lisezantsi kakhulu, isixhobo esomisa ifriji sinikwa ukhuseleko lokudlula amandla (oluphunyezwa ngevalve yokudlula okanye ivalve yefluorine solenoid). ).Xa iqondo lobushushu lendawo yombethe lingaphantsi kwe-0 °C, ivalve yokudlula (okanye ivalve ye-fluorine solenoid) izivula ngokuzenzekelayo (indawo yokuvula iyanda), kunye nobushushu obuphezulu obunganyuswanga kunye noxinzelelo oluphezulu lwesikhenkcezisi umphunga utofwa ngokuthe ngqo kwi-inlet ye-evaporator. (okanye itanki yokwahlula yolwelo lwerhasi kwindawo yokungenisa icompressor), ukuze iqondo lombethe linyuke liye kutsho ngaphezulu kwe-0 °C.
C. Ngokombono wenkqubo yokusetyenziswa kwamandla, ukushisa kwe-evaporation kuphantsi kakhulu, okubangelwa ukuhla okukhulu kwi-coefficient yefriji ye-compressor kunye nokwanda kokusetyenziswa kwamandla.
