Iimbuyekezo zolwelo
1. Kwinkqubo yefriji esebenzisa i-valve yokwandisa, i-valve yokubuyisela inxulumene ngokusondeleyo nokukhetha kunye nokusetyenziswa okungafanelekanga kwe-valve yokwandisa.Ukhetho olukhulu kakhulu lwe-valve yokwandisa, ukusetwa kwe-overheat encinci, indlela engafanelekanga yokufakela iphakheji yokuva iqondo lokushisa okanye umonakalo wokupakisha i-adiabatic. , ukusilela kwevalve yokwandisa kunokukhokelela ekubuyeni kolwelo.
2. Kwizixokelelwano zefriji ezincinci zisebenzisa ii-capillaries, ubuninzi obugqithisileyo bokongeza ulwelo kuya kubangela ukubuya kolwelo.Xa iqabaka evaporator ibetha kakubi okanye ifeni isilela, ukuhanjiswa kobushushu kuba kubi kakhulu. ukubuya.
Umatshini uqala ngolwelo
Isenzeko sokugqabhuka kakhulu kweoli yokuthambisa kwicompressor ibizwa ngokuba kuqalwa ngolwelo.Into eqhumayo ngexesha lokuqalisa kolwelo inokubonwa ngokucacileyo kwi-oil scope.Isizathu esingundoqo kukuba isixa esikhulu sefriji sinyibilika i-oyile yokuthambisa kwaye ifakwe kwi-oyile yokuthambisa.Xa uxinzelelo lwehla ngokukhawuleza, ngokukhawuleza luyabila.
I-oyile ibuya
1. Xa indawo ye-compressor iphezulu kune-evaporator, i-oyile yokubuyisela i-oyile igobile kumbhobho wokubuyisela iyimfuneko.Buyisela i-oyile igobile ngokukhawuleza kangangoko kunokwenzeka ukunciphisa ukugcinwa kweoli.Umgama phakathi kwe-oyile yokubuyisela i-oyile kufuneka ulungele , ubungakanani be-oil return bend bukhulu, enye ioli yokuthambisa kufuneka yongezwe.
2. Ukuqala rhoqo kwe-compressor akuncedi ukubuya kweoli.Ngenxa yokuba i-compressor yayeka ukusebenza ixesha elifutshane kakhulu, kwakungekho xesha lokwenza ukuhamba komoya okuzinzile kwisantya esiphezulu kwipayipi yokubuyisela, ngoko ke ioli yokuthambisa yayinokuba kuphela. Icompressor iya kuphelelwa yi-oyile ukuba i-oyile yokubuya ingaphantsi kwe-oyile ehambayo.Ixesha lokusebenza liba lifutshane, kokukhona umbhobho omde, kokukhona intsonkothe inkqubo, kokukhona ingxaki yokubuya kwe-oyile inzima.
3. Ukunqongophala kweoli kuya kubangela ukunqongophala okukhulu kwe-lubrication.Isizathu esisisiseko sokunqongophala kweoli asikho isixa kunye nesantya se-compressor, kodwa ukubuyiswa kweoli embi kwenkqubo.
Ubushushu bobushushu
Ubushushu bobushushu bunempembelelo enkulu ekusebenzeni kakuhle kwesikhenkcisi.Ngalo lonke ixesha iyancipha nge-1 idigri, umlinganiselo ofanayo wokupholisa ufuna ukwandisa amandla nge-4%.Ngoko ke, kunenzuzo ukunyusa ukusebenza kakuhle kokupholisa kwe-air conditioner ngokunyusa ubushushu be-evaporation ngokufanelekileyo phantsi kwemeko yokuvumela.
Ukunciphisa ngokungaboniyo ubushushu bomphunga kunokupholisa umahluko weqondo lobushushu, kodwa isixa sokupholisa ngecompressor sincitshisiwe, ngoko ke isantya sefriji asiyomfuneko ukuba sikhawuleze. ixesha elide lokuhamba, kokukhona usetyenziso lombane luphezulu.
Ubushushu obugqithisileyo bokukhupha
Izizathu zeqondo lokushisa eliphezulu lokukhupha zimi ngolu hlobo lulandelayo: ukushisa okuphezulu okubuyayo, ukushisa okuphezulu okongeziweyo yimoto, umlinganiselo woxinzelelo oluphezulu, uxinzelelo oluphezulu lwe-condensing, ukushisa kwe-adiabatic index ye-refrigerant, ukukhetha okungafanelekanga kwefriji.
Impembelelo yolwelo
1. Ukuze kuqinisekiswe ukusebenza okukhuselekileyo kwe-compressor kunye nokuthintela ukwenzeka kwe-percussion ye-liquid percussion, ubushushu bokufunxa bufuneka ukuba bube buphezulu kancinci kunobushushu bokufudumala, oko kukuthi, iqondo elithile lobushushu elifunekayo.
2. Ukushisa kwe-inhalation kufuneka kube phezulu kakhulu okanye kuphantsi kakhulu. Ukushisa okuphezulu kakhulu, oko kukuthi, ukufudumala kakhulu, kuya kukhokelela kubushushu obuphezulu becompressor. kwi-evaporator, enganciphisi nje ukusebenza ngokutshintshiselana kobushushu kwe-evaporator, kodwa yenza ukothuka kolwelo lwe-compressor. Ubushushu bokufunxa phantsi kweemeko eziqhelekileyo kufuneka bube yi-5 ~ 10 ℃ ngaphezulu kobushushu bomphunga.
I-Fluorine
Xa kukho i-fluoride encinci okanye uxinzelelo lwayo olulawulayo lusezantsi (okanye luvaleke kancinci), isigqubuthelo sevalve yevalve yokwandisa (iimvulo) okanye nendawo yokungena yevalvu iya kuba neqabaka. Xa isixa sefluorine sisincinci kakhulu okanye asinayo , ukubonakala kwevalve yokwandisa ayiphenduli, kuphela ukuhamba komoya omncinci kunokuvakala.
Jonga ukuba yeyiphi isiphelo seqhwa eqala ukusuka, ukusuka kwi-nozzle okanye kwi-compressor umva ukuya kwi-trachea, ukuba ukusuka kwi-nozzle ukungabikho kwe-fluorine, ukusuka kwi-compressor ininzi ye-fluorine.
Ubushushu obuphantsi bokufunxa
1. Ixabiso lokuzaliswa kwefriji lininzi kakhulu, lihlala inxalenye yomthamo we-condenser kunye nokwandisa uxinzelelo lokunciphisa, kwaye i-liquid engena kwi-evaporator iya kwanda ngokufanelekileyo. Ngethontsi yolwelo.Ngoko, ubushushu bombhobho werhasi obuyayo buyancipha, kodwa ubushushu bomphunga buhlala bungatshintshi kuba uxinzelelo alwehli, kwaye nobushushu obukhulu buyancipha.Nokuvala ivalve encinci yokwandisa ayiphucukanga kakhulu.
2. Ivalve yokwandisa ivulwe inkulu kakhulu.Ngenxa yokubopha okukhululekileyo kwezinto zokuvavanya ubushushu, indawo encinci yokudibanisa kunye nombhobho womoya wokubuyisela, okanye indawo engafanelekanga yokupakisha izinto zokuva ubushushu ngaphandle kwezixhobo ze-adiabatic, ubushushu obulinganiswe yizinto zokuvavanya ubushushu azichanekanga. kwaye kufutshane nobushushu be-ambient, okwandisa iqondo lokuvula intshukumo yevalvu yokwandisa kwaye ikhokelele kunikezelo lolwelo olugqithisileyo.
Ubushushu obuphezulu bokufunxa
1. Kwinkqubo, umlinganiselo wokuzaliswa kwefriji akwanelanga, okanye i-valve yokwandisa ivuliwe encinci kakhulu, okubangela ukuba inani elinganeleyo lokujikeleza kwefriji yenkqubo, kwaye i-refrigerant dosage ye-evaporator iphantsi kwaye i-superheat iphezulu, ngoko iqondo lobushushu lokufunxa liphezulu.
2. Isikrini sokucoca kwizibuko levalve yokwandisa livalekile, ubungakanani bolwelo olunikezelweyo kwi-evaporator alanele, ubungakanani bolwelo lwefriji luyancitshiswa, kwaye inxalenye ye-evaporator ihlalwa ngumphunga oshushu kakhulu, ngoko ke ubushushu bokufunxa buyanda. .
3. Ngenxa yezinye izizathu, ukushisa kwe-inhalation kuphezulu kakhulu, njengokufudumeza ubushushu obubi bombhobho womoya obuyayo okanye umbhobho omde kakhulu, onokubangela ukuba ukushisa kwe-inhalation kuphakame kakhulu. ipholile, ishushu isiqingatha.
Ubushushu obuphantsi bokukhupha
Uxinzelelo lwe-exhaust luphantsi kakhulu, nangona i-phenomenon yayo ibonakaliswe ekupheleni koxinzelelo oluphezulu, kodwa isizathu sisoloko siphantsi koxinzelelo oluphantsi.Izizathu zezi:
1. Ibhloko yomkhenkce okanye ibhloko emdaka yevalve yokwandisa, ibhloko yesihluzi, njl. njl., ngokuqinisekileyo iya kunciphisa uxinzelelo kunye nokukhupha uxinzelelo;
2. Umngxuma wevalve yokwandisa uvaliwe, kwaye ukunikezelwa kolwelo kuyancitshiswa okanye kumiswe.Ngeli xesha, ukufunxa kunye nokukhupha uxinzelelo kuyancipha.
HERO-TECH Industrial amanzi chiller
Iicompressor ezidumileyo zehlabathi ezamkelweyo kunye necondenser ephezulu kunye ne-evaporator, iqinisekisa ukusebenza kakuhle kokupholisa, ukusetyenziswa kwamandla okuphantsi, ingxolo ephantsi kunye nobomi benkonzo ende.
Umphunga ongaphezulu kobukhulu kunye necondenser iqinisekisa iyunithi ye-chiller esebenza ngaphantsi kwe-45ºC yobushushu obuphezulu be-ambient.
Inkqubo yokulawula iMicrocomputer enikezela uzinzo oluchanekileyo lobushushu ngaphakathi ±1ºC.
Ubume be-evaporator-in-tanki obuqalayo buqinisekisa ubushushu bamanzi obuzinzileyo obubonelelwayo, njengoko i-evaporator ikwayipholisa itanki ngokwayo, inciphisa ubushushu be-ambient kwakhona, kwaye yonyusa ukusebenza kakuhle.
