I-R407F iyifriji eyakhiwe ngabakwa-Honeywell.Ixube u-R32, u-R125 no-R134a, kanti ihlobene no-R407C, kodwa inengcindezi ehambisana kangcono no-R22, u-R404A no-R507.Nakuba i-R407F ekuqaleni yayihloselwe ukufaka esikhundleni sika-R22 kodwa manje isisetshenziswa nasezinhlelweni zezitolo ezinkulu lapho i-GWP yayo engu-1800 iyenza ibe ngaphansi kwe-GWP esikhundleni sika-R22 ene-GWP engu-3900. ama-molecule njengoba futhi anokwakheka okufanayo ne-R407C, futhi wonke ama-valve neminye imikhiqizo yokulawula egunyazwe u-R22/R407C nayo isebenza kahle nge-R407F.
Ukukhetha i-Compressor:
Lo mhlahlandlela wokufaka kabusha noma ukufaka ama-compressor emishinini entsha enohlu lwethu lwamanje ubuyekeziwe ngezincomo zobuchwepheshe zokushintsha u-R22 ngezingxube ezingaba khona ezitholakala emakethe njenge-R407F.
Ukukhetha i-valve:
Lapho ukhetha i-valve yokwandisa i-thermostatic ukhethe i-valve engase isetshenziselwe kokubili u-R22 no-R407C, njengoba ijika lomfutho womoya lihambisana nalawa mavalvu kangcono kunamavalvu asebenziseka kuphela ngo-R407C.Ukuze uthole ukulungiselelwa okulungile kokushisa okuphezulu, ama-TXV kufanele alungiswe kabusha ngokuthi "ukuvulwa" ngo-0.7K (ku -10C).Amandla wamavalvu okunweba we-thermostatic ane-R-407F azoba makhulu cishe ngo-10% kunomthamo we-R-22.
Inqubo yokushintsha:
Ngaphambi kokuqala ukushintsha, okungenani izinto ezilandelayo kufanele zitholakale kalula: ✮ Izibuko zokuphepha
✮ Amagilavu
✮ Izikali zesevisi yesiqandisi
✮ I-thermometer ye-elekthronikhi
✮ Iphampu ye-vacuum ekwazi ukudonsa u-0.3 mbar
✮ I-Thermocouple micron gauge
✮ Umtshina ovuzayo
✮ Iyunithi yokubuyisela efrijini kuhlanganise nesilinda esiqandisini
✮ Isitsha esifanele sokuthambisa esikhishiwe
✮ Idivayisi entsha yokulawula uketshezi
✮ Isihlungi somshini wokukhipha uketshezi esikhundleni (izi)
✮ Isigcobo se-POE esisha, lapho sidingeka
✮ Ishadi lezinga lokushisa lomfutho we-R407F
✮ Isiqandisi sika-R407F
1. Ngaphambi kokuqala ukuguqulwa, isistimu kufanele ihlolwe kahle ukuvuza nesiqandisi se-R22 sisekhona ohlelweni.Konke ukuvuza kufanele kulungiswe ngaphambi kokuthi kwengezwe isiqandisi se-R407F.
2. Kuyatuseka ukuthi izimo zokusebenza kwesistimu (ikakhulukazi ukumunca nokukhipha izingcindezi eziphelele (isilinganiso sokucindezela) kanye nokushisa okuphezulu kakhulu endaweni yokufaka i-compressor) zirekhodwe kanye ne-R22 esekhona ohlelweni.Lokhu kuzohlinzeka ngedatha eyisisekelo ukuze iqhathaniswe lapho isistimu ibuyiselwa ekusebenzeni ne-R407F.
3. Nqamula amandla kagesi ohlelweni.
4. Khipha kahle i-R22 kanye ne-Lub.Amafutha avela ku-compressor.Linganisa futhi uqaphele inani elisusiwe.
5. Shintsha isihlungi somugqa owuketshezi ufake esihambisana no-R407F.
6. Shintsha ivalvu yokunweba noma isici samandla ufake imodeli egunyazwe u-R407C (idingeka kuphela lapho kufakwa kabusha isuka ku-R22 iye ku-R407F).
7. Khipha uhlelo uye ku-0.3 mbar.Ukuhlolwa kokubola kwevacuum kuyaphakanyiswa ukuze kuqinisekiswe ukuthi isistimu yomile futhi ayivuzi.
8. Shaja kabusha uhlelo ngo-R407F nowoyela we-POE.
9. Shaja uhlelo ngo-R407F.Shaja ku-90% wesiqandisi esikhishwe entweni 4. I-R407F kufanele ishiye isilinda sokushaja esigabeni soketshezi.Kuphakanyiswa ukuthi ingilazi yokubona ixhunywe phakathi kwepayipi lokushaja kanye nevalvu yesevisi yokumunca i-compressor.Lokhu kuzovumela ukulungiswa kwe-valve yesilinda ukuqinisekisa ukuthi isiqandisi singena ku-compressor esimweni somhwamuko.
10. Sebenzisa uhlelo.Rekhoda idatha bese uqhathanisa nedatha ethathwe entweni 2. Hlola futhi ulungise ukulungiselelwa kokushisa okuphezulu kwe-TEV uma kudingeka.Yenza izinguquko kwezinye izilawuli njengoba kudingeka.I-R407F eyengeziwe kungase kudingeke yengezwe ukuze kutholwe ukusebenza kwesistimu okuphelele.
11. Lebula kahle izingxenye.Maka i-compressor ngesiqandisi esisetshenzisiwe (R407F) kanye nesithambisi esisetshenzisiwe.
