Indima yezinto eziphambili zokomisa efrijini

1. Isiguquli sefriji

Ii-compressors zefriji zingundoqo kwinkqubo yokufriji, kwaye uninzi lwee-compressors namhlanje zisebenzisa ii-compressors eziguquguqukayo ezifakwa kwi-hermetic. Ukuphakamisa i-refrigerant ukusuka kuxinzelelo oluphantsi ukuya koluphezulu kwaye ijikeleza i-refrigerant rhoqo, inkqubo iqhubeka nokukhupha ubushushu bangaphakathi kwindawo engaphezulu kobushushu benkqubo.

2. Isikhondensi

Umsebenzi we-condenser kukupholisa umphunga we-refrigerant oxinezelekileyo, oshushu kakhulu okhutshwa yi-refrigerant compressor uye kwi-refrigerant engamanzi, kwaye ubushushu bayo bususwa ngamanzi apholisayo. Oku kuvumela inkqubo ye-refrigerant ukuba iqhubeke ngokuqhubekayo.

3. Isitshisi-moya

I-evaporator yeyona nto iphambili ekutshintshiselaneni kobushushu kwi-friji dryer, kwaye umoya ocinezelweyo upholiswa ngenkani kwi-evaporator, kwaye uninzi lomphunga wamanzi luyapholiswa luze lufakwe emanzini angamanzi kwaye lukhutshwe ngaphandle komatshini, ukuze umoya ocinezelweyo wome. Ulwelo lwe-refrigerant oluphantsi koxinzelelo luba ngumphunga we-refrigerant ophantsi koxinzelelo ngexesha lotshintsho lwesigaba kwi-evaporator, lufunxa ubushushu obujikelezileyo ngexesha lotshintsho lwesigaba, ngaloo ndlela lupholisa umoya ocinezelweyo.

4. Ivalvu yokwandisa i-thermostatic (i-capillary)

Ivalvu yokwandisa i-thermostatic (i-capillary) yindlela yokuqhobosha yenkqubo yokuqhobosha. Kwisixhobo sokomisa ifriji, ukunikezelwa kwe-evaporator refrigerant kunye nomlawuli wayo kwenziwa ngenkqubo yokuqhobosha. Indlela yokuqhobosha ivumela ifriji ukuba ingene kwi-evaporator isuka kulwelo olunobushushu obuphezulu nolunoxinzelelo oluphezulu.

5. Isitshintshi sobushushu

Uninzi lwee-dryer zefriji zine-heat exchanger, eyi-heat exchanger etshintshiselana ubushushu phakathi komoya nomoya, ngokubanzi yi-tubular heat exchanger (eyaziwa ngokuba yi-shell and tube heat exchanger). Umsebenzi ophambili we-heat exchanger kwi-friji dryer kukubuyisela amandla okupholisa athwalwa ngumoya ocinezelweyo emva kokuba upholiswe yi-evaporator, kwaye usebenzise le nxalenye yamandla okupholisa ukupholisa umoya ocinezelweyo kubushushu obuphezulu obuphethe umphunga omkhulu wamanzi (oko kukuthi, umoya ocinezelweyo ogcweleyo okhutshwa kwi-air compressor, opholiswe yi-cooler engasemva ye-air compressor, uze wahlulwe ngumoya namanzi ngokubanzi ungaphezulu kwama-40 °C), ngaloo ndlela kunciphisa umthwalo wobushushu wenkqubo yefriji nokomisa kwaye kufezekiswe injongo yokonga amandla. Kwelinye icala, ubushushu bomoya ocinezelweyo obushushu obuphantsi kwi-heat exchanger buyafunyanwa, ukuze udonga lwangaphandle lombhobho othutha umoya ocinezelweyo lungabangeli "ukufuma" ngenxa yobushushu obungaphantsi kobushushu obuqhelekileyo. Ukongeza, emva kokuba ubushushu bomoya oxinzelelweyo bunyukile, umswakama womoya oxinzelelweyo emva kokomiswa uyancitshiswa (ngokubanzi ungaphantsi kwama-20%), nto leyo eluncedo ekuthinteleni umhlwa wesinyithi. Abanye abasebenzisi (umz. ngezityalo zokwahlula umoya) bafuna umoya oxinzelelweyo onomswakama omncinci kunye nobushushu obuphantsi, ngoko ke i-friji dryer ayisaxhotyiswa nge-heat exchanger. Ekubeni i-heat exchanger ingafakwanga, umoya obandayo awunakuphinda usetyenziswe, kwaye umthwalo wobushushu we-evaporator uya kwanda kakhulu. Kule meko, akufuneki nje kuphela ukuba amandla e-friji compressor anyuswe ukuze kuhlawulwe amandla, kodwa nezinye izinto zenkqubo yonke yefriji (i-evaporator, i-condenser kunye nezinto ezithintela umoya) kufuneka zonyuswe ngokufanelekileyo. Ngokwembono yokubuyiselwa kwamandla, sisoloko sinethemba lokuba xa ubushushu bomoya oxinzelelweyo buphezulu, kokukhona kungcono (ubushushu bomoya obuphezulu, okubonisa ukubuyiswa kwamandla amaninzi), kwaye kungcono ukuba kungabikho mahluko kubushushu phakathi kwendawo yokungena kunye nendawo yokuphuma. Kodwa eneneni, akunakwenzeka ukufezekisa oku, xa ubushushu bokungena komoya bungaphantsi kwama-45°C, akuqhelekanga ukuba ubushushu bokungena kunye nobokuphuma komshini wokomisa ifriji buhluke ngaphezu kwe-15°C.

Ukucubungula Umoya Ocinezelweyo

Umoya ocinezelweyo→ izihluzi zoomatshini→ izitshintshi zobushushu (ukukhululwa kobushushu), →izitshizi → izahluli zegesi-ulwelo→ izitshintshi zobushushu (ukufunxwa kobushushu), → izihluzi zoomatshini zokukhupha igesi→ iitanki zokugcina igesi

Ukugcinwa nokuhlolwa: gcina ubushushu obuphantsi kombethe wesixhobo sokuqandisa ifriji bungaphezulu kwe-zero.

Ukunciphisa ubushushu bomoya ocinezelweyo, ubushushu bokufuma kwefriji kufuneka bube sezantsi kakhulu. Xa i-friji dryer ipholisa umoya ocinezelweyo, kukho umaleko we-condensate efana nefilimu kumphezulu we-fin ye-evaporator liner, ukuba ubushushu bomphezulu we-fin bungaphantsi kwe-zero ngenxa yokwehla kobushushu bokufuma, i-condensate yomphezulu inokubanda, ngeli xesha:

A. Ngenxa yokuncamatheliswa komaleko womkhenkce onomoya wobushushu omncinci kakhulu kumphezulu wephiko langaphakathi lesinyi se-evaporator, ukusebenza kakuhle kokutshintshiselana kobushushu kuncitshisiwe kakhulu, umoya ocinezelweyo awunakupholiswa ngokupheleleyo, kwaye ngenxa yokufunxwa kobushushu okwaneleyo, ubushushu bokufuma kwefriji bunokuncipha ngakumbi, kwaye isiphumo somjikelo onjalo ngokuqinisekileyo siya kuzisa iziphumo ezininzi ezimbi kwinkqubo yokufriji (ezifana "nokucinezelwa kolwelo");

B. Ngenxa yesithuba esincinci phakathi kwamaphiko kwi-evaporator, xa amaphiko eqandisiwe, indawo yokujikeleza komoya oxinzelelweyo iya kuncipha, kwaye nendlela yomoya iya kuvalwa kwiimeko ezinzima, oko kukuthi, "ukuvaleka komkhenkce"; Ngamafutshane, ubushushu be-compression dew point ye-friji dryer kufuneka bube ngaphezulu kwe-0 °C, ukuze kuthintelwe ubushushu be-dew point ukuba bungabi phantsi kakhulu, i-friji dryer inikwa ukhuselo lwe-energy bypass (olufezekiswa yi-bypass valve okanye i-fluorine solenoid valve). Xa ubushushu be-dew point buphantsi kwe-0 °C, i-bypass valve (okanye i-fluorine solenoid valve) ivuleka ngokuzenzekelayo (ukuvulwa kuyanda), kwaye umphunga we-refrigerant ongenaxinzelelo oluphezulu noluphezulu ufakwa ngqo kwi-inlet ye-evaporator (okanye itanki yokwahlula igesi-ulwelo kwi-compressor inlet), ukuze ubushushu be-dew point bunyuswe bube ngaphezulu kwe-0 °C.

C. Ngokwembono yokusetyenziswa kwamandla kwinkqubo, ubushushu bokufuma buphantsi kakhulu, nto leyo ebangela ukwehla okukhulu kwi-compressor friji coefficient kunye nokwanda kokusetyenziswa kwamandla.
