Ama-cooler angu-40 emishini yokuqandisa, i-Refrigerator, izisekelo ze-Freezer

1. Ukushisa okumuncwa yi-refrigerant kusuka endaweni epholile lapho ibila futhi iphenduka umhwamuko ku-evaporator kubizwa ngokuthi amandla okupholisa ohlelweni lokuqandisa.

2. Ngaphezu kokushintsha kwesimo segesi noketshezi, i-refrigerant izophinde ibe nokushintsha kwesimo segesi noketshezi ngesikhathi sokujikeleziswa ohlelweni lokuqandisa.

3.Ukufaka esiqandisini kuyinqubo yokudlulisa ukushisa okuphambene futhi ayinakwenziwa ngokuzenzekelayo.

4. Ingcindezi evame ukukhulunywa ngayo ohlelweni lokuqandisa empeleni ibhekisela ekucindezelweni, okungukuthi, ingcindezi ngendawo ngayinye.

5. Inani lokushisa elidlulisiwe lilingana nendawo yokudlulisa ukushisa kanye nomehluko wokushisa kokudlulisa ukushisa, kodwa alinalutho oluphathelene nobukhulu bokudlulisa ukushisa, noma kufanele lilingane nobubanzi bokudlulisa ukushisa.

6. Ukuncibilika kwegesi kungatholakala ngokucindezela noma ukupholisa, noma ngabe igesi idlula izinga lokushisa elibucayi. 7. Ukusetshenziswa kokushisa okuphezulu komusi emjikelezweni wokuqandisa ukugwema amaconsi amanzi angena ku-compressor futhi abangele isando soketshezi kunokwandisa i-coefficient yokuqandisa.

8. I-oda lokushisa lokukhipha umoya kusukela phansi kuya phezulu ku-R717, R22, kanye no-R134a ngaphansi kwezimo ezifanayo zokusebenza lingu-R134a < R22 < R717.

9. Uma i-viscosity kawoyela wokugcoba iphezulu kakhulu, izinga lokushisa lokukhipha umoya lizoba phezulu kakhulu, kodwa uma liphansi kakhulu, lingabangela ukugcotshwa okubi kunokushisa kokukhipha umoya ngokweqile.

10. Ukungcola okweqile ebusweni be-evaporator kuzokwenza izinga lokushisa lokuhwamuka kwe-refrigerant lehle, futhi amandla okusebenza e-compressor anganda.

11. Ukusetshenziswa kwe-supercooling ewuketshezi emjikelezweni wokuqandisa kuhlale kuzuzisa ekuthuthukiseni ukusebenza komjikelezo wokuqandisa.

12. Uma usebenzisa i-brine njengesiqandisi, njengoba izinga lokushisa lokuqina kwe-brine liyahlukahluka ngokuhlushwa, ukuhlushwa kwe-brine kukhethwa ngokusekelwe ekushiseni kokuqina kwesisombululo okungaba ngu-5°C ngaphansi kwezinga lokushisa lokuhwamuka kwesiqandisi.

13. Izinga le-vacuum libhekisela emehluko phakathi kokucindezela okuphelele koketshezi olusebenzayo esitsheni kanye nokucindezela kwangaphandle komoya.

14. Uma nje izinga lokushisa lobuso lento liphakeme kunephuzu lamazolo lomoya, izinga lokushisa ngeke lijiye.

15. Ingqikithi yesiqandisi ukudlulisa ukushisa kwento enokushisa okuphansi endaweni enokushisa okuphezulu.

16. Inhloso yokupholisa uketshezi lwesiqandisi ukunciphisa igesi ye-flash ekhiqizwa ngesikhathi senqubo yokubhoboza, ngaleyo ndlela kwandiswe umthamo wokupholisa weyunithi.

17. Uwoyela wokuqandisa osetshenziswa ku-compressor yokuqandisa awukwazi ukushintshwa uwoyela wenjini ojwayelekile.

18. I-Montreal Protocol ithi amazwe asathuthuka azoyeka ukusebenzisa i-refrigerant yesikhashana i-R22 ngo-2030.

19. Izakhiwo ze-thermodynamic ze-R134a zisondele kakhulu kweze-R12. Ukusebenzisa i-R134a ukufaka esikhundleni se-R12 kudinga ukulungiswa okuthile ohlelweni ngoba izakhiwo zomzimba zazo zombili zihlukile.

20. Amapayipi okudlulisa ukushisa e-ammonia condenser ngokuvamile awakhiwa ngamapayipi ethusi ngoba i-ammonia nethusi kuzosabela.

21. I-Amonia imunca kahle amanzi, kodwa emazingeni okushisa aphansi, amanzi azophuma oketshezini lwe-ammonia bese eqandisa. Kodwa-ke, okwenzeka ohlelweni akukhona “ukuvala iqhwa”, kodwa kungabangela ukuvaleka kwamapayipi.

22. Amapayipi ethusi ngokuvamile awasetshenziswa kumapayipi efriji ezinhlelweni zokuqandisa ze-ammonia ngoba i-ammonia nethusi kuzosabela.

23. Kuyiqiniso ukuthi i-Freon ayigqwali izinsimbi, kodwa eziningi zazo zingancibilikiswa ku-oyili.

24. Ama-athomu e-chlorine ku-Freon ayimbangela eyinhloko yokubhujiswa kongqimba lwe-ozone olusemkhathini, hhayi i-fluorine.

25. Inqubo yangempela yokusebenza kwe-compressor ye-piston ihlanganisa izinqubo zokumunca, ukucindezela, ukukhipha, kanye ne-valve yokwandisa.

26. Akuzona zonke izinhlelo zokuqandisa ezidinga ukufaka imishini yokomisa. Zidingeka kuphela uma kusetshenziswa amafriji athile futhi kungenzeka ukuthi kuvalwe iqhwa.

27. Ukufundwa kwesilinganiso sokucindezela kuyingcindezi elinganiselwe (ingcindezi yokulinganisa), hhayi ingcindezi ephelele.

28. Iphuzu lokubila loketshezi lihlobene nengcindezi. Uma ingcindezi iphakeme, kulapho izinga lokubila liphakama khona.

29. Isiqandisi siyindlela esetshenziswa ohlelweni lokuqandisa olungaqondile, oluhlukile kwesiqandisi.

30. Ukuqandisa kuyinqubo yokwehlisa izinga lokushisa lesikhala noma into ethile nokugcina leli zinga lokushisa ngezindlela zokwenziwa.

31. Umsebenzi womhlukanisi wamafutha ohlelweni lokuqandisa ukuhlukanisa uwoyela wokugcoba ne-refrigerant, hhayi ukuvimbela amanzi ukuthi angaxubeki ku-oyela wokugcoba.

32. I-evaporator iyithuluzi lokushintshanisa ukushisa elimunca ukushisa lapho i-refrigerant ihwamuka.

33. Uma uketshezi noma igesi yesiqandisi ishiswa kusilinda, izokwandisa ingcindezi, yenze kube nzima ukunwebeka futhi iqhume kalula.

34. I-R134a iyisiqandisi esiphephile. Isithambisi sayo akuwona uwoyela wamaminerali, kodwa uwoyela we-polyester wokwenziwa.

35. I-R134a iyisiqandisi esingenayo i-chlorine. Ayinawo umthelela omubi ongqimbeni lwe-ozone olusemkhathini, kodwa iyigesi ebamba ukushisa. Uma isikhishwe emkhathini, izothuthukisa umphumela we-greenhouse.

36. I-R22 isetshenziswa kabanzi kuma-air conditioner nama-cooler asekhaya nawamabhizinisi endawo. Iyi-refrigerant ye-HCFC futhi ivinjelwe emazweni asathuthuka ngo-2030.

37. Uma i-ammonia iphuma ohlelweni lokuqandisa bese ixubana nomoya ngesilinganiso esithile, kuzoba yingozi ukuyidubula nokuqhuma lapho ihlangana nomlilo.

38. Umthamo wokushisa othize uyinkomba yokukala ukusebenza kwesiqandisi, kodwa akuyona yodwa inkomba ebalulekile.

39. Amandla okupholisa e-compressor enkulu yokuqandisa angaphezulu kuka-550kw.

40. Iziqandisi ezixubile zihlukaniswe ngeziqandisi ze-azeotropic kanye neziqandisi ezingezona ezeotropic.
