Zininzi iindlela zokukhenkceza, kwaye ezi zilandelayo zisetyenziswa ngokuqhelekileyo:
1. Ifriji yokwenziwa ngumphunga
2. Ukwandiswa kwegesi kunye nefriji
3. I-Vortex tube efrijini
4. Ukupholisa iThermoelectric
Phakathi kwazo, ifriji ye-vaporization yamanzi yeyona isetyenziswa kakhulu.Isebenzisa isiphumo sokufunxa ubushushu somphunga wolwelo ukufikelela kwifriji.Ukunyanzeliswa komphunga, ukufunxwa, inaliti yomphunga kunye nefriji ye-adsorption zonke zizikhenkcezisi zolwelo.
Isibandisi sokucinezelwa komphunga sisesikhenkcezini sokutshintsha isigaba, esebenzisa isiphumo sokufunxa ubushushu xa isibandisi sitshintsha ukusuka kulwelo ukuya kwirhasi ukufumana amandla abandayo. Iqulethwe ngamacandelo amane: icompressor, i-condenser, i-throttling mechanism kunye ne-evaporator.Zidibaniswe ngokutshintshana ngemibhobho ukwenza inkqubo evaliweyo.
Iinxalenye eziphambili zefriji kunye nezixhobo
1.Icompressor
Iicompressors zohlulwe zibe zizakhiwo ezithathu: uhlobo oluvulekileyo, uhlobo oluvulekileyo, kunye nohlobo oluvaliweyo.Umsebenzi we-compressor kukufunxa i-refrigerant ephantsi yobushushu ukusuka kwicala le-evaporator, kwaye uyicinezele kwi-high-pressure, i-high-temperature vapour epholileyo kwaye uyithumele kwi-condenser.
2.Icondenser
I-condenser sisixhobo sokutshintshiselana kobushushu esihambisa amandla efriji ye-evaporator kwi-system yefriji kunye nomsebenzi wokubonakalisa ukunyanzeliswa kwe-compressor kwi-medium medium (amanzi okupholisa okanye umoya).Ngokwendlela yokupholisa, i-condenser inokwahlulwa ibe yi-air-cooled, epholile ngamanzi kunye ne-evaporative. I-condenser sisixhobo sokutshintshiselana kobushushu esihambisa amandla efriji ye-evaporator kwi-system yefriji kunye nomsebenzi wokubonakalisa ukunyanzeliswa kwe-compressor kwi-medium medium (amanzi okupholisa okanye umoya).Ngokwendlela yokupholisa, i-condenser inokwahlulwa ibe yi-air-cooled, epholile ngamanzi kunye ne-evaporative.
3. Umphunga
I-evaporator ithetha ukuba ulwelo lwefriji luyabila kwaye lufunxa ubushushu bendawo epholileyo (umoya okanye amanzi) kwiqondo lobushushu elisezantsi ukuze kuphunyezwe injongo yesikhenkcisi.
4. Ivalve yeSolenoid
Ivalve yeSolenoid luhlobo lwevalve yokuvala ezivulelekayo phantsi kolawulo lombane.Ngokuqhelekileyo ifakwe kumbhobho wenkqubo ukucima ngokuzenzekelayo kunye nokucima i-activator yomlawuli weendawo ezimbini zombhobho wenkqubo yefriji.Ivalve ye-solenoid idla ngokufakwa phakathi kwevalve yokwandisa kunye ne-condenser. Indawo kufuneka ibe kufutshane kangangoko kwivalvu yokwandisa, kuba ivalve yokwandisa yinto nje ebethayo kwaye ayinakuvalwa ngokwayo, ngoko ke ivalve yesolenoid mayisetyenziselwe ukusika umbhobho wonikezelo lolwelo.
5.Ivalve yokwandisa iThermal
Izixhobo zokukhenkceza zihlala zisebenzisa iivalve zokwandisa i-thermal ukulungisa ukuhamba kwefriji.Akuyona kuphela i-valve elawulayo elawula ukunikezelwa kolwelo lwe-evaporator, kodwa kunye ne-valve ye-throttle yesixhobo sefriji.Ivalve yokwandisa i-thermal isebenzisa utshintsho kwi-superheat ye-refrigerant ekuphumeni kwe-evaporator ukulungelelanisa ukunikezelwa kwamanzi.Ivalve yokwandiswa kwe-thermal idityaniswe kumbhobho wolwelo wokungena we-evaporator, kwaye ibhalbhu yokuva ubushushu ibekwe kumbhobho wokuphuma evaporator (ophumayo) umbhobho.Ngokuqhelekileyo yahlulahlulwe ngokwezakhiwo ezahlukeneyo ngokwesakhiwo sevalve yokwandisa i-thermal:
(1) Ivalve yokwandisa ubushushu yangaphakathi;
(2) Ivalve yokwandisa i-thermal yangaphandle.
Ivalve yokwandisa i-thermal yangaphakathi: Iqulethwe ngebhalbhu yokuva ubushushu, ityhubhu ye-capillary, isihlalo sevalve, i-diaphragm, intonga ye-ejector, inaliti yevalve kunye nokulungelelanisa.Iivalvu zokwandiswa kwe-thermal ezilungeleleneyo zangaphakathi zisetyenziswa ngokubanzi kwii-evaporators ezincinci.
Ivalve yokwandiswa kwe-thermal elungeleleneyo yangaphandle: Ivalve yokwandiswa kwe-thermal elungeleleneyo yangaphandle Kwi-evaporators enemibhobho emide okanye ukuxhathisa okukhulu, iivalvu zokwandisa thermal ezilungeleleneyo zangaphandle zihlala zisetyenziswa.Kwi-evaporator yobukhulu obufanayo, i-valve yangaphakathi yokwandisa i-valve ingasetyenziselwa xa isetyenziswe kwindawo yokugcina ukushisa, ngelixa i-valve yokwandisa ukulinganisela ngaphandle ingasetyenziselwa xa isetyenziswe kwindawo yokugcina iqondo lokushisa eliphantsi.Kwi-evaporator yobukhulu obufanayo, i-valve yangaphakathi yokwandisa i-valve ingasetyenziselwa xa isetyenziswe kwindawo yokugcina ukushisa, ngelixa i-valve yokwandisa ukulinganisela ngaphandle ingasetyenziselwa xa isetyenziswe kwindawo yokugcina iqondo lokushisa eliphantsi.
6. Isahluli seoli
I-oil separator ivame ukufakwa phakathi kwe-compressor kunye ne-condenser ukwahlula ioli yomshini wefriji efakwe kwi-vapor yefriji.Isixhobo sokubuyisela ioli sisetyenziselwa ukubuyisela ioli yomshini wefriji kwi-crankcase ye-compressor;isakhiwo esisetyenziswa ngokuqhelekileyo isahluli yeoli ineentlobo ezimbini: uhlobo lwe-centrifugal kunye nohlobo lokucoca.
7. Isahluli segesi-ulwelo
Ukwahlula i-gaseous refrigerant kwi-refrigerant yamanzi ukukhusela i-compressor kwihamile yamanzi;gcina ulwelo lwefriji kumjikelezo wefriji, kwaye ulungelelanise unikezelo lwamanzi ngokwenguqu yomthwalo.
8. Indawo yokugcina amanzi
Ngokumisela i-accumulator, umthamo wokugcinwa kwamanzi we-accumulator ungasetyenziselwa ukulinganisela kunye nokuzinzisa ukujikeleza kwefriji kwisistim, ukwenzela ukuba isixhobo sefriji sisebenze ngokuqhelekileyo.I-accumulator ibekwe ngokubanzi phakathi kwe-condenser kunye ne-throttling element.Ukuze i-refrigerant yamanzi kwi-condenser ingene kwi-accumulator ngokufanelekileyo, indawo ye-accumulator kufuneka ibe ngaphantsi kwe-condenser.
9. Isomisi
Ukuze kuqinisekiswe ukujikeleza okuqhelekileyo kwefriji, inkqubo yefriji kufuneka igcinwe icocekile kwaye yomile.Isixhobo sokucoca isihluzi sihlala sihlohlwa phambi kwento yokuthontsiza.Xa ifriji yolwelo idlula kuqala kwisihluzi sokucoca, inokuthintela ngokufanelekileyo ukuvaleka kwi-throttling element.
10. Iglasi yokubona
Ngokukodwa isetyenziselwa ukubonisa imeko yefriji kwipayipi yamanzi yesixhobo sefriji kunye nomthamo wamanzi kwifriji.Ngokuqhelekileyo, imibala eyahlukileyo iphawulwe kwimeko yeglasi yokubona ukubonisa umxholo wamanzi wefriji kwinkqubo.
11. I-relay ye-voltage ephezulu kunye nephantsi
Ukuba uxinzelelo lokukhutshwa kwe-compressor luphezulu kakhulu, luya kuqhawula ngokuzenzekelayo, lumise i-compressor kwaye luphelise unobangela woxinzelelo oluphezulu, kwaye emva koko ukusetha kwakhona ngesandla ukuqalisa i-compressor (i-fault + alarm);xa uxinzelelo lokufunxa luwela kumda ophantsi, luya kuqhawula ngokuzenzekelayo.Misa i-compressor, kwaye unike amandla i-compressor kwakhona xa uxinzelelo lwe-suction lunyukela kumda ophezulu.
12. Ukuhanjiswa koxinzelelo lweoyile eyahlukileyo
Ukutshintsha kombane osebenzisa umahluko woxinzelelo phakathi kokufunxa kunye nokukhutshwa kwempompo yeoli yokuthambisa njengophawu lolawulo, xa umahluko wexinzelelo ungaphantsi kwexabiso elibekiweyo, umisa icompressor ukuyikhusela.
13. Ukuhanjiswa kobushushu
Sebenzisa ubushushu njengophawu lolawulo ukulawula ubushushu bogcino olubandayo.Ukuqala kunye nokuyeka kwe-compressor kunokulawulwa ngokuthe ngqo ngokulawula kunye nokuphuma kwevalve ye-solenoid yolwelo;xa umatshini omnye uneebhanki ezininzi, ukuhanjiswa kweqondo lokushisa kwibhanki nganye kunokudityaniswa ngokuhambelana nokulawula ukuqala okuzenzekelayo kunye nokuyeka kwe-compressor.
14. Isikhenkcisi
Iifriji, ezikwaziwa ngokuba ziifriji kunye neefriji, zizinto zemidiya ezisetyenziswa kwiinjini ezahlukeneyo zobushushu ukugqiba uguqulo lwamandla.Ezi zinto zihlala zisebenzisa iinguqu zesigaba ezibuyiselwa umva (ezifana neenguqu zesigaba segesi-ulwelo) ukwandisa amandla.
15. Ioli yefriji
Umsebenzi we-oyile yomatshini wefriji ikakhulu ukugcoba, ukutywina, ukupholisa kunye nokucoca.Kwiicompressor ezininzi ze-cylinder, ioyile yokuthambisa ingasetyenziselwa ukulawula indlela yokukhulula.
