I-R407F sisikhenkcisi esaveliswa nguHoneywell.Ingumxube we-R32, i-R125 kunye ne-R134a, kwaye inxulumene ne-R407C, kodwa inoxinzelelo oluhambelana ngcono ne-R22, i-R404A kunye ne-R507.Nangona i-R407F yayicetyelwe ekuqaleni njengokutshintshwa kwe-R22 ngoku ikwasetyenziswa kwizicelo zevenkile enkulu apho i-GWP yayo ka-1800 iyenza ibe yi-GWP ephantsi endaweni ye-R22 ene-GWP engama-3900. Njengoko kubonisiwe kulo mfanekiso, i-R407F isekelwe kulo iimolekyuli njengoko kwaye inokwakheka okufanayo kwi-R407C, kwaye zonke iivalvu kunye nezinye iimveliso zolawulo ezivunyiweyo nge-R22/R407C nazo zisebenza kakuhle nge-R407F.
Ukukhetha isicinezeli:
Esi sikhokelo sokufakwa ngokutsha okanye ukufakela izixhobo zokucinezela izixhobo ezitsha ezinoluhlu lwethu lwangoku sihlaziywe ngeengcebiso zobugcisa zokutshintsha i-R22 kunye nemixube ekhoyo ekhoyo kwimarike efana ne-R407F.
Ukukhetha ivalvu:
Xa ukhetha ivalve yokwandisa i-thermostatic ukhethe ivalve enokusetyenziswa kuzo zombini i-R22 kunye ne-R407C, ekubeni ijiko loxinzelelo lomphunga lihambelana nezi zivalo ngcono kuneevalvu ezisebenziseka kuphela nge-R407C.Ukulungiselela ukusetwa kobushushu obuchanekileyo, ii-TXVs kufuneka zihlengahlengiswe kwakhona ngokuthi "opening" ngo-0.7K (at -10C).Amandla okwandisa i-thermostatic valves nge-R-407F iya kuba malunga ne-10% enkulu kunomthamo we-R-22.
Inkqubo yoTshintsho:
Phambi kokuba uqalise utshintsho, ubuncinane ezi zinto zilandelayo mazifumaneke lula: ✮ Iiglasi zokhuseleko
✮ Iiglavu
✮ Iigeyiji zenkonzo yefriji
✮ Ithemometha ye-elektroniki
✮ Impompo yokufunxa ekwaziyo ukutsala i-0.3 mbar
✮ Igeji ye-micron ye-Thermocouple
✮ Isibonisi esivuzayo
✮ Iyunithi yokubuyisela kwisikhenkcezisi kubandakanya isilinda esikhenkcezileyo
✮ Isikhongozeli esifanelekileyo se-lubricant esusiweyo
✮ Isixhobo esitsha sokulawula ulwelo
✮ Ukutshintshwa komgca wolwelo wesihluzi-somiso (s)
✮ I-lubricant ye-POE entsha, xa ifuneka
✮ itshathi yobushushu boxinzelelo lwe-R407F
✮ R407F ifriji yefriji
1. Ngaphambi kokuqala ukuguqulwa, isistim kufuneka ihlolwe ngokucokisekileyo ukuvuza kunye nefriji ye-R22 isekho kwisistim.Zonke iindawo ezivuzayo kufuneka zilungiswe phambi kokuba kongezwe ifriji ye-R407F.
2. Kucetyiswa ukuba iimeko zokusebenza kwesistim (ingakumbi i-suction and discharge absolute pressures (pressure ratio) kunye ne-suction superheat kwi-compressor inlet) zirekhodwe kunye ne-R22 esesistim.Oku kuya kubonelela ngesiseko sedatha yokuthelekisa xa inkqubo ibuyiselwa ekusebenzeni kunye ne-R407F.
3. Nciphisa amandla ombane kwisistim.
4. Susa ngokufanelekileyo i-R22 kunye neLub.Ioli evela kwicompressor.Ukulinganisa kwaye uqaphele imali esusiweyo.
5. Faka endaweni yesihluzo sokucoca ulwelo ngesinye esihambelanayo ne-R407F.
6. Faka endaweni yesivalo sokwandisa okanye isiqalelo samandla kwimodeli evunyiweyo nge-R407C (ifuneka kuphela xa kulungiswa ngokutsha ukusuka kwi-R22 ukuya kwi-R407F).
7. Phuma inkqubo kwi-0.3 mbar.Uvavanyo lokubola kwevacuum luyacetyiswa ukuqinisekisa ukuba inkqubo yomile kwaye ayivuzi.
8. Hlaziya inkqubo kwakhona nge-R407F kunye ne-oyile ye-POE.
9. Shaja inkqubo nge-R407F.Umrhumo ukuya kwi-90% yefriji ekhutshwe kwinqaku 4. I-R407F mayishiye isilinda sokutshaja kwinqanaba le-liquid.Kucetyiswa ukuba iglasi yokubona mayidityaniswe phakathi kwethumbu lokutshaja kunye nevalve yenkonzo yokufunxa icompressor.Oku kuya kuvumela ukulungiswa kwevalve yesilinda ukuqinisekisa ukuba ifriji ingena kwicompressor kwimeko yomphunga.
10. Sebenzisa inkqubo.Rekhoda idatha kwaye uthelekise idatha ethathwe kwinqaku 2. Khangela kwaye ulungise i-TEV i-superheat setting ukuba kuyimfuneko.Yenza uhlengahlengiso kolunye ulawulo njengoko lufuneka.I-R407F eyongezelelweyo inokufuneka idityaniswe ukuze kufunyanwe eyona nkqubo isebenzayo.
11. Ileyibheli ngokufanelekileyo amacandelo.Taga icompressor ngefriji esetyenzisiweyo (R407F) kunye ne-lubricant esetyenzisiweyo.
