Iinkqubo zefriji zokusebenzisa zisebenzisa iifriji njengokusebenza kukalwelo, kwaye i-frients ngokubanzi ineefom ezimbini: ulwelo kunye negesi. Namhlanje siza kuthetha ngolwazi olufanelekileyo malunga nembali yolwelo.
1. Ngaba i-frientl yolwelo okanye irhasi?
Iifriji zinokwahlulwa zibe zizigaba ezi-3: Iifriji zeRiveranti yeRiverantic, iiMbali ezixubileyo ezixubileyo, kunye ne-Azeopsrapic Gutywerges.
Ukuqulunqwa kwemali yenyama enye yokusebenza akuyi kutshintsha nokuba iluhlaza okanye i-wale, ngoko i-Gaseous State inokuhlawuliswa xa ihlawulisa ifriji.
Nangona ukwakhiwa kwefriji ye-Azeotrapic yahlukile, kuba indawo yokubila iyafana, ukwakhiwa kwegesi kunye nolwelo kukwanjalo, ke irhasi inokuhlawuliswa;
Ngenxa yamanqaku ahlukeneyo abilayo abaziingcali zefrijini ze-azeotropic, iifriji zeerrimo ezingamanzi kunye ne-Gaseous Ripers zahlukile. Ukuba i-Gaseous Riverpors yongezwa ngeli xesha, ukwakhiwa kweefriji zeRiverfrients kuya kwahluka. Umzekelo, kuphela intlangconi ye-gesious yongezwa. Ifriji, nje yongezwa kuphela ulwelo.
Oko kukuthi, imbali yezopolitiko ye-azeotropic kufuneka yongezwe kunye nolwelo, kwaye i-no-azeotropropic yefriji yonke iqalile nge-R4. Olu hlobo lolo longezwa. I-R401a, R403B, R403A, R407A, R407A, R407A, R409A, R411A, R411A, R411A, R411A.
Ngokubhekisele kwezinye iifriji eziqhelekileyo, ezinje nge: R134A, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R32, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R22, R200A, ukwenziwa kwefriji akuyi kuvunywa kwegesi okanye ulwelo, ngoko ke kufanelekile.
Xa sisongeza ifriji, kufuneka sinikele ingqalelo kwezi zilandelayo:
(1) Qwalasela amaqamza kwiglasi yokujonga;
(2) ukulinganisa uxinzelelo oluphezulu nolusezantsi;
(3) ukulinganisa i-compressor okwangoku;
(4) Silinganisa inaliti.
Ukongeza, kufuneka kuqatshelwe kwaye igxininisile loo nto:
Iifriji ze-AzeoTropic kufuneka zongezwe kwimeko yolwelo. Umzekelo, i-R410A ihlaziyi, ukwakhiwa kwayo yile ilandelayo:
I-R32 (DislumOmethane): 50%;
I-R125 (i-pentafluoeroethane): 50%;
Kuba iindawo ezibilayo ezingama-R32 ne-R125 zahlukile, xa i-R410A ishiywe ishiywe, i-R32 + ikhokelela kwi-R32 ye-R125, ngenxa yokuba inqaku lokubila i-R32 liphantsi, Kusenokwenzeka ukuba inxenye ephezulu yefriji yinxalenye ye-R32.
Ke ngoko, ukuba i-Gaseous Free frient yongezwa, ifriji eyongeziweyo ayisiyo-R410A, kodwa i-R32.
Okwesibini, iingxaki eziqhelekileyo zeefriji zeerrimo
I-1. I-Scied Fiderant Sokufuduswa
Ukufuduka kwefrijini kubhekisele ekuqulunqweni kwengcali yolwelo kwi-crankssor crankser xa i-compressor ivaliwe. Logama nje iqondo lobushushu ngaphakathi kwi-compressor lipholile kuneqondo lokushisa ngaphakathi kwi-Evaporator, umahluko phakathi koxinzelelo kunye ne-Evaporator iya kuqhuba ifriji kwindawo epholileyo. Le phenomenon inokwenzeka ukuba yenzeke kubusika ababandayo. Nangona kunjalo, kwizinto eziphakamileyo zomoya kunye neempompo zokutshisa, xa iyunithi ye-condenclousing ikude kakhulu kwi-compressor, ukufuduka kunokwenzeka nokuba amaqondo obushushu aphezulu.
Nje ukuba inkqubo ivaliwe, ukuba ayivulwanga kwiiyure ezimbalwa, nokuba akukho mahluko woxinzelelo, i-fugonon inokwenzeka ngenxa yokuthwala ifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji kwifriji.
Ukuba i-proint yefriji ye-flued ifudukela kwiCrankresse yeCoceressor, i-Slam ye-Slam ye-Slam ye-Slam iyaqaliswa, ngenxa yokuthoba i-up rasion, i-piston yomonakalo, i-irosion igungxula ioyile evela kwiibheri).
I-2. Ifriji yefriji yefriji
Xa ivalve yokwandiswa iyasilela, okanye i-Evaporator fan iyasilela okanye ivalwe yi-filter yomoya, impumelelo ye-propurants iya kugqobhoza kwi-Evaporator kwaye ingene kwi-comporessor ngokusebenzisa i-vapor. Xa iyunithi iyasebenza, ngenxa yokupheliswa kolwelo ekuphumeni kweoyile yokuthambisa, iindawo ezihambayo ze-compressor zinxitywe, kwaye uxinzelelo lweoyile luyasebenza, ngaloo ndlela lubangela i-cranksest ilahlekelwe ioyile. Kule meko, ukuba umatshini uvaliwe, i-phenomenon yokufuduka ifriji iya kukhawuleza, imphumo kwi-flumer shemert yokuqalisa kwakhona.
I-3. Ukubetha kolwelo
Xa i-hammer yolwelo yenzekile, isinyithi sentsimbi yentsimbi evela ngaphakathi kwi-compressor inokuviwe, kwaye inokuhamba kunye nokuntywila kobundlobongela kwe-compressor. I-Slam ye-Liqual inokubangela i-valve upupture, i-compressor ye-garket ye-radit, iqhagamshela ukwaphuka kwe-rod, ukonakaliswa kwe-cranksshaft, kunye nomonakalo kwezinye iindlela zefomati. I-Shemmer ye-flumer yenzeka xa ifriji yoLwanti ifudukela kwi-cranksest kwaye iqale kwakhona. Kwezinye iiyunithi, ngenxa yesakhiwo sombhobho okanye indawo yamacandelo, impumelelo yefriji iya kuqokelela kwi-pubing okanye i-evaporator ngexesha lokuvalwa kweyunithi kwaye ifake isantya esiphezulu xa i-interreyishini ivuliwe. . Isantya kunye ne-Inria ye-Slal ye-Slad yanele ukohlula ukhuseleko olwakhelwe kwi-cestres malunga nolwelo.
I-4. Inyathelo lesixhobo solawulo lokhuseleko lwe-hydraulic
Kwiseti yeeyunithi zeqondo lobushushu ezisezantsi, emva kwexesha eliphezulu, isixhobo solawulo lomondolozo lweOyile lihlala libangelwa ukuba senze ngenxa yokugcwala kwengqondo yolwelo. Iinkqubo ezininzi zenzelwe ukuvumela i-resrants ukuba iphucule kwi-Evaporator kunye ne-Suction Prerost, kwaye emva koko ifike kwi-Constresser Crank Compresses kwi-Starpression enokubangela ukuba isebenze.
Ngamaxesha athile izenzo enye okanye ezimbini zesixhobo soLawulo lweOli Aliyi kuba nefuthe elibi kwi-compressor, kodwa liphindaphindwe kaninzi ngaphandle kweemeko ezilungileyo zembambano ziya kubangela ukuba i-compressor izokusilela. Isixhobo soLawulo loKhuseleko lweOyile sihlala sithathwa njengempazamo encinci ngumqhubi, kodwa sisilumkiso sokuba umcombululo sele esebenza ngaphezulu kwemizuzu emibini ngaphandle kokuqinisekiswa, kunye namanyathelo okulungisa kufuneka aphunyezwe ngexesha.
I-3. Izisombululo kwingxaki yeefriji zoLwandle
Icompressor eyilelwe kakuhle, esebenzayo yefriji, imeko yomoya, kunye neempompo zobushushu ziyimpompo ye-vapor enokuphatha kuphela isixa esithile se-ofisi kabusika kunye neoyile ye-oyile. Ukwenzela ukuba uyila i-compressor enokuthi ikwazi ukuthwala iifriji zeerrive zefriji kunye neoyile yefriji, ukudityaniswa kobungakanani, ubunzima, amandla okupholisa, ingxolo kunye nexabiso kufuneka kuthathelwe ingqalelo. Ngaphandle kwezinto zoyilo, isixa sefriji ye-solicrants apho i-compressor inokuthi ilungiswe, kwaye umthamo wayo ophetheyo uxhomekeke kwezi zinto zilandelayo: Uhlobo lwenkqubo kunye nolawulo lwenkqubo, kunye neemeko eziqhelekileyo zokusebenza.
Xa intlawulo yentlawulo iyanda, iya kukwandisa ingozi enokubakho kwi-compressor. Izizathu zomonakalo zinokuchazwa ngokwala manqaku alandelayo:
(1) Intlawulo egqithisileyo yokuhlawula.
(2) I-Evaporator icekeceke.
(3) Isihluzi se-Evaporator singcolile kwaye sivinjelwe.
(4) I-Evaporate fan okanye i-fan fan iyasilela.
(5) Ukukhetha okungachanekanga okungalunganga.
(6) Ukukhetha okanye uhlengahlengiso lwevalve yokwandisa ayichanekanga.
(7) Ukufuduka kwefriji.
