R407F waa qaboojiye ay samaysay Honeywell.Waa isku darka R32, R125 iyo R134a, waxayna la xiriirtaa R407C, laakiin waxay leedahay cadaadis si fiican u dhigma R22, R404A iyo R507.In kasta oo R407F markii hore loogu talagalay beddelka R22, haddana waxa sidoo kale loo adeegsadaa codsiyada dukaamada waaweyn halkaas oo GWP-giisa 1800 uu ka dhigayo beddelka GWP hoose ee R22 kaas oo leh GWP ah 3900. Sida ku cad shaxanka, R407F waxay ku saleysan tahay isla isla. molecules sida oo uu leeyahay halabuurka la mid ah R407C, iyo dhammaan valves iyo alaabta kale ee kontoroolka kuwaas oo loo ansixiyay R22/R407C sidoo kale waxay si fiican ula shaqeeyaan R407F.
Xulashada Compressor:
Tilmaantan dib-u-habaynta ama rakibidda kombaresarada ee qalab cusub oo leh kala duwanaantayada hadda waxa lagu cusboonaysiiyay talooyinka farsamo ee lagu beddelayo R22 oo leh isku-dhafka suurtagalka ah ee laga heli karo suuqa sida R407F.
Xulashada Valve:
Marka la dooranayo waalka ballaadhinta heerkulbeeggu waxa uu doortay waalka loo isticmaali karo R22 iyo R407C labadaba, maadaama qalooca uumiga uumiga la mid yahay valves-yadan oo ka fiican valves kaliya ee la isticmaali karo R407C.Si loo dejiyo kulaylka saxda ah, TXVs waa in dib loogu hagaajiyaa "furitaanka" 0.7K (at -10C).Awoodaha balaadhinta heerkulbeegga ee leh R-407F waxay noqon doontaa qiyaastii 10% ka weyn awoodda R-22.
Habka beddelka:
Kahor intaadan bilaabin beddelka, ugu yaraan walxaha soo socda waa inay diyaar ahaadaan: ✮ Muraayadaha badbaadada
✮ galoofyada
✮ Qalabka adeega qaboojiyaha
Heerkulbeeg elektaroonik ah
✮ Vacuum bamka awood u leh inuu jiido 0.3 mbar
✮ Thermocouple micron cabirka
✮ Dareeraha dheecaanka
✮ Cutubka soo kabashada qaboojiyaha oo ay ku jiraan dhululubada qaboojiyaha
✮ Weel sax ah oo saliid laga saaray
✮ Qalabka cusub ee xakamaynta dareeraha
✮ Beddelida shaandhada khadka dareeraha ah-qalajiyaha
✮ Saliidda POE cusub, marka loo baahdo
✮ R407F shaxda heerkulka cadaadiska
✮ R407F qaboojiyaha
1. Kahor intaadan bilaabin beddelka, nidaamka waa in si fiican loo tijaabiyaa qaboojiyaha R22 ee wali ku jira nidaamka.Dhammaan meelaha daadsan waa in la hagaajiyo ka hor intaan qaboojiyaha R407F lagu darin.
2. Waxaa lagu talinayaa in xaaladaha hawlgalka nidaamka (gaar ahaan nuugista iyo dheecaanka cadaadis buuxda (cadaadiska saamiga) iyo nuugista superheat ee kombaresarada gudaha) la duubay iyadoo R22 weli ku jira nidaamka.Tani waxay ku siin doontaa xogta aasaasiga ah marka la barbardhigo marka nidaamka lagu soo celiyo shaqada R407F.
3. Ka saar awoodda korontada iyo nidaamka.
4. Si sax ah uga saar R22 iyo Lub.Saliidda kombaresarka.Cabbir oo ogow qaddarka laga saaray.
5. Ku beddel qalajiyaha khadka dareeraha ah mid ku habboon R407F.
6. Ku beddel waalka ballaadhinta ama element korantada qaab loo oggolaaday R407C (kaliya ayaa loo baahan yahay marka dib loo habayn doono R22 ilaa R407F).
7. Ka saar nidaamka ilaa 0.3 mbar.Tijaabada suuska faakuumka ayaa la soo jeediyay si loo hubiyo in nidaamku engegan yahay oo uu xor yahay.
8. Ku buuxi nidaamka R407F iyo saliid POE.
9. Ku dallac nidaamka R407F.Ku dallac 90% qaboojiyaha laga saaray shayga 4. R407F waa in uu kaga tagaa dhululubada ku dallaca wejiga dareeraha ah.Waxa la soo jeediyay in muraayadda aragga lagu xidho inta u dhaxaysa tuubada dallacaadda iyo waalka adeegga nuugista kombaresarada.Tani waxay ogolaanaysaa hagaajinta waalka dhululubada si loo hubiyo in qaboojiyaha uu galo kombaresarka xaalada uumiga.
10. Ku shaqee nidaamka.Diiwaangeli xogta oo barbar dhig xogta lagu qaaday shayga 2. Hubi oo hagaaji goobta kulaylka sare ee TEV haddii loo baahdo.Ku hagaaji kontaroolada kale haddii loo baahdo.R407F dheeraad ah ayaa laga yaabaa in lagu daro si loo helo waxqabadka nidaamka ugu wanaagsan.
11. Si sax ah u calaamadee qaybaha.Ku dheji kombarada qaboojiyaha la isticmaalay (R407F) iyo saliidda la isticmaalay.
