Izixhobo zokuFriji ezingama-40, iiFriji, iZiseko zeFriji

1. Ubushushu obufunxwa yi-refrigerant kwindawo epholileyo xa ibila kwaye inyibilika kwi-evaporator bubizwa ngokuba ngumthamo we-friji wenkqubo ye-friji.

2. Ukongeza kutshintsho lwemeko yegesi-ulwelo, i-refrigerant iya kuba notshintsho lwemeko yegesi-ulwelo ngexesha lokujikeleza kwenkqubo yokufriji.

3.Ukukhenkceza yinkqubo yokudlulisela ubushushu ngendlela ebuyela umva kwaye ayinakwenziwa ngokuzenzekelayo.

4. Uxinzelelo oluqhelekileyo olubhekiselwa kulo kwinkqubo yokukhenkceza lubhekisa kuxinzelelo, oko kukuthi, uxinzelelo kwindawo nganye.

5. Ubungakanani bobushushu obudlulisiweyo bulingana nendawo yokudlulisa ubushushu kunye nomahluko wobushushu obudlulisiweyo, kodwa abunanto yakwenza nobukhulu bokudlulisa ubushushu, okanye kufuneka bulingane nobukhulu bokudlulisa ubushushu obugqithisileyo.

6. Ukunyibilika kwegesi kunokufezekiswa ngokucinezela okanye ukupholisa, nokuba igesi idlula ubushushu obubalulekileyo. 7. Ukusetyenziswa kobushushu obuphezulu bomphunga kumjikelo wokufriji kukuthintela amathontsi olwelo angene kwi-compressor aze abangele ihamile yolwelo endaweni yokwandisa i-coefficient yokufriji.

8. Ulandelelwano lobushushu bomphunga ukusuka kwesezantsi ukuya kwephezulu kwi-R717, R22, kunye ne-R134a phantsi kweemeko ezifanayo zokusebenza yi-R134a < R22 < R717.

9. Ukuba i-viscosity yeoyile yokuthambisa iphezulu kakhulu, ubushushu bomphunga buya kuba phezulu kakhulu, kodwa ukuba buphantsi kakhulu, bunokubangela ukuthambisa okungekho semgangathweni kunobushushu bomphunga obugqithisileyo.

10. Ukungcola okugqithisileyo kumphezulu we-evaporator kuya kubangela ukuba ubushushu bokufuma kwe-refrigerant bunciphe, kwaye umsinga wokusebenza we-compressor unokwanda.

11. Ukusetyenziswa kwe-supercooling engamanzi kumjikelo wokukhenkceza kusoloko kuluncedo ekuphuculeni ukusebenza komjikelo wokukhenkceza.

12. Xa usebenzisa i-brine njenge-refrigerant, ekubeni ubushushu bokuqina kwe-brine buyahluka ngokoxinzelelo, uxinzelelo lwe-brine lukhethwa ngokusekelwe kubushushu bokuqina kwesisombululo obumalunga ne-5°C iphantsi kuneqondo lobushushu bokufuma kwefriji.

13. I-vacuum degree ibhekisa kumahluko phakathi koxinzelelo olupheleleyo lolwelo olusebenzayo kwisitya kunye noxinzelelo lwangaphandle lomoya.

14. Logama nje ubushushu bomphezulu wento buphezulu kuneqondo lombethe womoya, ubushushu abuyi kujika.

15. Eyona nto ibalulekileyo xa kusenziwa ifriji kukudlulisela ubushushu bento enobushushu obuphantsi kwindawo enobushushu obuphezulu.

16. Injongo yokupholisa ulwelo olubandayo kukunciphisa igesi ephuma kwi-flash eveliswa ngexesha lenkqubo yokuqhobosha, ngaloo ndlela kwandiswa amandla okupholisa eyunithi.

17. Ioyile yokupholisa esetyenziswa kwi-compressor yokupholisa ayinakutshintshwa yioyile yenjini esetyenziswa ngokubanzi.

18. I-Montreal Protocol ithi amazwe asakhulayo aza kuyeka ukusebenzisa i-refrigerant yenguqu i-R22 ngo-2030.

19. Iimpawu ze-thermodynamic ze-R134a zisondele kakhulu kwezo ze-R12. Ukusebenzisa i-R134a endaweni ye-R12 kufuna uhlengahlengiso oluthile kwinkqubo kuba iimpawu zomzimba zezi zimbini zahlukile.

20. Iityhubhu zokudlulisa ubushushu ze-ammonia condenser aziqhelekanga ukuba zenziwe ngeetyhubhu zobhedu kuba i-ammonia kunye ne-copper ziya kuphendula.

21. I-Ammonia ifunxa kakuhle amanzi, kodwa kumaqondo obushushu aphantsi, amanzi aya kuphuma kwi-ammonia liquid aze aqine. Nangona kunjalo, okwenzekayo kwinkqubo asikokuqhekeka komkhenkce, kodwa kunokubangela ukuvaleka kwemibhobho.

22. Iityhubhu zekopolo azisetyenziswa rhoqo kwiipayipi zefriji kwiinkqubo zefriji ze-ammonia kuba i-ammonia kunye nekopolo ziya kuphendula.

23. Liyinyaniso elokuba iFreon ayidli iintsimbi, kodwa uninzi lwazo lunokunyibilikiswa kwioyile.

24. Iiathom zeklorini ezikwiFreon zezona zibangela ukutshatyalaliswa komaleko we-ozone esemoyeni, hayi i-fluorine.

25. Inkqubo yokusebenza yokwenyani yecompressor yepiston ibandakanya iinkqubo zokufunxa, zokucinezela, zokukhupha umoya, kunye neenkqubo zevalvu yokwandisa.

26. Ayizizo zonke iinkqubo zokukhenkcisa ekufuneka zifake ii-dryer. Zifuneka kuphela xa kusetyenziswa ii-refrigerants ezithile kwaye kunokwenzeka ukuba kuthintelwe umkhenkce.

27. Ukufundwa kwigeyiji yoxinzelelo kuxinzelelo oluhambelanayo (uxinzelelo lokulinganisa), kungekhona uxinzelelo olupheleleyo.

28. Iqondo lokubila lolwelo linxulumene noxinzelelo. Okukhona uxinzelelo luphezulu, kokukhona iqondo lokubila liphezulu.

29. I-refrigerant yindlela esetyenziswa kwinkqubo yokukhenkceza engathanga ngqo, eyahlukileyo kwi-refrigerant.

30. Ukukhenkceza yinkqubo yokunciphisa ubushushu bendawo okanye into ethile kunye nokugcina obu bushushu ngeendlela zokwenziwa.

31. Umsebenzi womhluzi weoyile kwinkqubo yokukhenkcisa kukwahlula ioyile yokuthambisa kwifriji, kungekhona ukuthintela amanzi ekuxubeni kwioyile yokuthambisa.

32. I-evaporator sisixhobo sokutshintshiselana nobushushu esifunxa ubushushu xa i-refrigerant iphuma.

33. Ukuba ulwelo okanye igesi efrijini ifudunyezwa kwisilinda, iya kunyusa uxinzelelo, nto leyo eyenza kube nzima ukwanda kwaye kube lula ukuqhuma.

34. I-R134a yifriji ekhuselekileyo. I-lubricant yayo ayisiyooyile yeminerali, kodwa yioyile yepolyester eyenziweyo.

35. I-R134a yifriji engenalo i-chlorine. Ayinampembelelo intshabalalo kumaleko we-ozone emoyeni, kodwa yigesi ye-greenhouse. Nje ukuba ikhutshelwe emoyeni, iya kuphucula impembelelo ye-greenhouse.

36. I-R22 isetyenziswa kakhulu kwii-air conditioner zasekhaya nezamashishini kunye nee-coolers zasekuhlaleni. Yi-refrigerant ye-HCFC kwaye ayivumelekanga kumazwe asakhasayo ngo-2030.

37. Ukuba i-ammonia iphuma kwinkqubo yokukhenkcisa ize ixubane nomoya ukuya kwinqanaba elithile, iya kuba yingozi ukuyidubula nokuqhuma xa idibana nomlilo.

38. Umthamo othile wobushushu sisalathisi sokulinganisa ukusebenza kwefriji, kodwa asikuko kuphela isibonakaliso esibalulekileyo.

39. Umthamo wokupholisa wecompressor enkulu yokukhenkceza ungaphezulu kwe-550kw.

40. Iifriji ezixutyiweyo zahlulwe zibe ziifriji ze-azeotropic kunye neefriji ezingezizo ze-azeotropic.
