Ko te R407F he whakamahana i hangaia e Honeywell.He whakakotahitanga o R32, R125 me R134a, he hononga ki te R407C, engari he pehanga e pai ake ana ki te R22, R404A me R507.Ahakoa ko te R407F i mua hei whakakapinga R22 ka whakamahia ano inaianei i roto i nga tono hokomaha kei reira tana GWP o 1800 ka waiho hei iti ake te GWP rereke ki te R22 he GWP o 3900. Ka rite ki te whakaahua i runga i te ahua, ko te R407F kei runga i te taua. ngota ngota rite he rite te hanganga ki te R407C, me nga marere katoa me etahi atu hua whakahaere e whakaaetia ana mo te R22/R407C ka mahi pai me te R407F.
Kōwhiringa kōpeke:
Ko tenei aratohu mo te whakahou, te whakauru ranei i nga miihini ki roto i nga taputapu hou me o taatau awhe o naianei kua whakahouhia me nga tohutohu hangarau mo te whakakapi i te R22 me nga whakakotahitanga pea kei te maakete penei i te R407F.
Whiriwhiri takirere:
I te wa e kowhiri ana i te riipene roha whakamaarama i kowhiria he takirere ka taea te whakamahi mo te R22 me te R407C, na te mea he pai ake te pai o te pehanga pehanga kohu ki enei marere i nga marere ka taea anake me te R407C.Mo te tautuhinga wera nui, me whakatika ano nga TXV ma te "tuwhera" ma te 0.7K (i te -10C).Ko nga kaha o nga reera roha whakamaarama me te R-407F ka tata ki te 10% te nui ake i te kaha mo te R-22.
Tikanga hurihanga:
I mua i te tiimata o te whakarereke, me waatea nga mea e whai ake nei: ✮ Mohiti haumaru
✮ karapu
✮ Nga mehua ratonga whakamahana
✮ Weahanga hiko
✮ Puma korehau kaha ki te toia 0.3 mbar
✮ Wehenga micron Thermocouple
✮ Kaitirotiro turuturu
✮ Waehanga whakaora whakamatao tae atu ki te puoto whakamahana
✮ He ipu tika mo te whakahinuhinu kua tangohia
✮ He taputapu whakahaere wai hou
✮ Whakakapi raina wai tātari-maroke(ngā)
✮ Whakahinuhinu POE hou, ina hiahiatia
✮ R407F tūtohi pāmahana pēhanga
✮ R407F whakamatao
1. I mua i te tiimata o te huringa, me tino whakamatauhia te punaha me te R22 i roto tonu i te punaha.Me whakatika katoa nga turuturu i mua i te whakaurunga o te R407F refrigerant.
2. He mea tika kia tuhia nga tikanga whakahaere o te punaha (ina koa ko te momi me te tukunga o te pehanga tino (te owehenga pehanga) me te wera nui o te momi i te kokoru compressor) me te R22 kei roto tonu i te punaha.Ma tenei ka whakarato i nga raraunga turanga mo te whakataurite ina whakahokia te punaha ki te mahi me te R407F.
3. Momotuhia te hiko hiko ki te punaha.
4. Tango tika te R22 me te Lub.Te hinu mai i te compressor.Te ine me te tuhi i te nui kua tangohia.
5. Whakakapia te tātari-maroke raina wai ki tetahi e hototahi ana ki te R407F.
6. Whakakapia te puera roha, huānga hiko ranei ki tetahi tauira kua whakaaetia mo te R407C (e hiahiatia ana ina whakahou mai i te R22 ki te R407F).
7. Whakanuia te punaha ki te 0.3 mbar.Ka whakaarohia he whakamatautau pirau korehau kia mohio kei te maroke te punaha me te kore e pakaru.
8. Whakahoutia te punaha ki te R407F me te hinu POE.
9. Utuhia te punaha ki te R407F.Me utu ki te 90% o te whakamahana i tangohia i te nama take 4. Me waiho e R407F te rango utu ki te wahanga wai.Ko te whakaaro me hono he karaihe tirohanga i waenga i te ngongo utu me te puera ratonga momi compressor.Ma tenei ka taea te whakarereketanga o te riipene rango hei whakapumau ka uru te pouaka whakamatao ki roto i te miihini i roto i te ahua kohu.
10. Whakahaerehia te punaha.Tuhia nga raraunga ka whakataurite ki nga raraunga i tangohia i te nama 2. Tirohia me te whakatika i te tautuhinga wera nui TEV ki te tika.Whakaritehia etahi atu mana whakahaere ina hiahiatia.Ko etahi atu R407F me taapiri kia whiwhi ai i te mahinga punaha tino pai.
11. Tapahia nga waahanga tika.Tohua te kaitapahi me te whakamatao i whakamahia (R407F) me te whakahinuhinu i whakamahia.
