Ezinye Izinhlobo Ezihlukene Zamafriji
Isiqandisi R600A
I-R600a iyisiqandisi esisha se-hydrocarbon esisebenza kahle kakhulu. Itholakala ezingxenyeni zemvelo, ezingalimazi ungqimba lwe-ozone, azinawo umphumela we-greenhouse, futhi ziluhlaza futhi zinobungani bemvelo.
Inokushisa okucashile okuphezulu kokuhwamuka namandla okupholisa aqinile: ukusebenza kahle kokugeleza, ukudluliswa okuphansi Ukucindezela, ukusetshenziswa kwamandla okuphansi, nokululama kancane kwezinga lokushisa lomthwalo. Ihambisana nama-compressor lubricant ahlukahlukene, ingenye ye-R12.R600a igesi evuthayo.
Isiqandisi R404A
I-R404A isetshenziswa ikakhulukazi ukushintsha u-R22 no-R502. Ibonakala ngokuhlanzeka, ubuthi obuphansi, ukungabi namanzi, nomphumela omuhle wesiqandisi. Isiqandisi se-R404A asinawo umthelela omubi kungqimba lwe-ozone
I-R404A yenziwe i-HFC125, i-HFC-134a, ne-HFC-143. Kuyigesi engenambala emazingeni okushisa asekamelweni kanye noketshezi olukhanyayo olungenambala uma ucindezela.
Ifanele imishini emisha yesiqandisi yezentengiselwano, okokusebenza kweziqandisi zokuthutha, kanye nemishini yesiqandisi emazingeni okushisa aphakathi nendawo naphansi.
Isiqandisi R407C
Isiqandisi i-R407C siyingxube yama-hydrofluorocarbon. I-R407C isetshenziswa kakhulu ukufaka esikhundleni sika-R22. Ihlanzekile, inobuthi obuphansi, ayishi, futhi inezimpawu zomphumela omuhle wesiqandisi.
Ngaphansi kwesiphephetha-moya, umthamo wokupholisa wevolumu yeyunithi kanye ne-coefficient yesiqandisi ingaphansi kuka-5% wama-R22. I-coefficient yayo yokupholisa ayishintshi kakhulu emazingeni okushisa aphansi, kodwa umthamo wayo wokupholisa ngeyunithi ngayinye ingaphansi ngo-20%.
Isiqandisi R717 ( Ammonia)
U-R717 (i-Amonia) i-ammonia esezingeni elibandayo esetshenziswa esiqandisini esisezingeni lokushisa eliphansi kuya kweliphakathi. Ayinambala futhi inobuthi kakhulu. Kodwa iyisiqandisi esisebenza kahle kakhulu esinamandla okufudumala kwembulunga yonke ayiziro.
Kulula ukuyithola, inenani eliphansi, ingcindezi ephakathi nendawo, ukupholisa iyunithi enkulu, i-coefficient ephezulu ye-exothermic, cishe ayincibiliki emafutheni, ukumelana nokugeleza okuncane. Kodwa iphunga liyacasula futhi linobuthi, lingashisa futhi liqhume.
Ukuqhathaniswa Kweziqandisi
Izici ezifiselekayo zesiqandisi esihle:
I-refrigerant substance ibhekwa njengesiqandisi esihle kuphela uma inalezi zinto ezilandelayo:
1. Iphuzu eliphansi lokubilisa
Indawo yokubilisa yesiqandisi esihle kufanele ibe ngaphansi kwalelozinga lokushisa ngokucindezelwa okuvamile njengezinga lokushisa elifiswa ukugcinwa okubandayo, ithange lobuchopho, noma enye indawo ebandayo. Okusho ukuthi, lapho isiqandisi sihwamuka.
Ukucindezela kumakhoyili esiqandisi kufanele kube phezulu kunokucindezela emoyeni ukuze ukuvuza kwesiqandisi kumakhoyili kubhekwe kalula.
2. Ukushisa Okucashile Kokuhwamuka
Ukushisa okucashile (inani lokushisa elidingekayo ukuze kushintshwe kusuka oketshezini kuya kugesi ezingeni lokushisa elifanayo) le-evaporator yesiqandisi esiwuketshezi kufanele libe phezulu.
Uketshezi olunokushisa okucashile okwengeziwe ngekhilogremu ngayinye kushiya umphumela wesiqandisi omkhudlwana ngokusebenzisa ukushisa okukhulu kunoketshezi olunokushisa okuncane okucashile.
3. Ivolumu Eqondile Ephansi
Umthamo ohlobene wegesi yesiqandisi kufanele ube mncane ukuze igesi eningi ingagcwaliswa kuCompressor ngesikhathi. Ubukhulu bomshini wesiqandisi bunqunywa ngokusekelwe ekushiseni okucashile kanye nomthamo ohlobene nesiqandisi.
4. Liquify At Lower Pressure
Isiqandisi esihle siphenduka uketshezi ngomfutho ophansi kuphela ngokusipholisa ngamanzi noma ngomoya. Lesi sakhiwo sitholakala e-ammonia (NH3).
Phawula:
Ezinye zezihloko zithathwe ku-inthanethi. Uma kukhona ukwephulwa komthetho, sicela usithinte ukuze ukususe. Uma uthanda imikhiqizo yephampu yokushisa, sicela ukhululeke ukuxhumana nenkampani yephampu yokushisa ye-OSB, siyisinqumo sakho esingcono kakhulu.
