R407F ni firigo yakozwe na Honeywell.Ni uruvange rwa R32, R125 na R134a, kandi rifitanye isano na R407C, ariko rufite igitutu gihuye neza na R22, R404A na R507.Nubwo R407F yari igenewe mbere yo gusimbuza R22 ubu irakoreshwa no muri supermarket aho GWP yayo ya 1800 ituma GWP yo hasi isimburwa na R22 ifite GWP ya 3900. Nkuko bigaragara ku gishushanyo, R407F ishingiye kuri kimwe molekile nkuko kandi ifite ibice bisa na R407C, hamwe na valve zose nibindi bicuruzwa byo kugenzura byemewe kuri R22 / R407C nabyo bikora neza hamwe na R407F.
Guhitamo compressor:
Aya mabwiriza yo guhindura cyangwa gushiraho compressor mubikoresho bishya hamwe nurwego rwubu byavuguruwe hamwe nibyifuzo bya tekinike yo gusimbuza R22 nibishobora kuvangwa ku isoko nka R407F.
Guhitamo Valve:
Iyo uhisemo kwaguka kwinshi kwa termostatike wahisemo valve ishobora gukoreshwa kuri R22 na R407C, kubera ko umurongo wumuvuduko wumuyaga uhuza iyi mibande neza kuruta imibiri ikoreshwa na R407C.Kugirango ushireho ubushyuhe bukabije, TXVs igomba kongera guhindurwa no "gufungura" kuri 0.7K (kuri -10C).Ubushobozi bwimyanya yo kwagura thermostatike hamwe na R-407F bizaba hafi 10% kurenza ubushobozi bwa R-22.
Uburyo bwo guhindura ibintu:
Mbere yo gutangira impinduka, byibuze ibintu bikurikira bigomba kuboneka byoroshye: glass Ibirahure byumutekano
Gants
Igipimo cya serivisi ya firigo
Therometero ya elegitoroniki
Pump Vacuum pump ishoboye gukurura 0.3 mbar
Microne ya microne
Det Detector
Unit Igice cyo kugarura firigo harimo na silinderi ya firigo
Contain Igikoresho gikwiye cyo gukuramo amavuta
Device Igikoresho gishya cyo kugenzura ibintu
Gusimbuza umurongo utemba wumurongo-wumye;
✮ Amavuta mashya ya POE, mugihe bikenewe
40 R407F imbonerahamwe yubushyuhe
40 firigo ya R407F
1. Mbere yo gutangira guhinduka, sisitemu igomba kumeneka neza hamwe na firigo ya R22 ikiri muri sisitemu.Ibisohoka byose bigomba gusanwa mbere ya firigo ya R407F.
2. Nibyiza ko imikorere yimikorere ya sisitemu (cyane cyane guswera no gusohora igitutu cyuzuye (igipimo cyumuvuduko) hamwe na superheat ya supressat yinjira) byandikwa hamwe na R22 ikiri muri sisitemu.Ibi bizatanga amakuru yibanze yo kugereranya mugihe sisitemu isubijwe mubikorwa hamwe na R407F.
3. Hagarika ingufu z'amashanyarazi kuri sisitemu.
4. Kuraho neza R22 na Lub.Amavuta ava muri compressor.Gupima kandi wandike amafaranga yakuweho.
5. Simbuza umurongo wamazi uyungurura-wumye hamwe na R407F.
6. Simbuza kwaguka valve cyangwa imbaraga zicyitegererezo cyemewe kuri R407C (bisabwa gusa mugihe uhinduye kuva kuri R22 ukagera kuri R407F).
7. Kwimura sisitemu kuri 0.3 mbar.Ikizamini cyangirika kirasabwa kwemeza ko sisitemu yumye kandi ikarekura ubusa.
8. Ongera usubize sisitemu hamwe namavuta ya R407F na POE.
9. Kwishyuza sisitemu hamwe na R407F.Kwishyuza 90% bya firigo yakuwe mubintu 4. R407F igomba gusiga silinderi yumuriro mugice cyamazi.Birasabwa ko ikirahure cyo kureba cyahuzwa hagati yumuriro wa charge na compressor suction service valve.Ibi bizemerera guhinduranya valve ya silinderi kugirango wizere ko firigo yinjira muri compressor mumyuka.
10. Koresha sisitemu.Andika amakuru hanyuma ugereranye namakuru yafashwe mubintu 2. Reba kandi uhindure igenamiterere rya TEV nibiba ngombwa.Hindura ubundi bugenzuzi nkuko bikenewe.Inyongera R407F irashobora kongerwaho kugirango ubone imikorere myiza ya sisitemu.
11. Andika neza ibice.Shyira compressor hamwe na firigo yakoreshejwe (R407F) hamwe namavuta yakoreshejwe.
