Zvave pedyo kuwana zvinotsiva zvechipiri-nechitatu-chizvarwa refrigerants!
Musi waGunyana 15, 2021, "Kigali Amendment kuMontreal Protocol yeZvinhu Zvinopedza Ozone Layer" yakatanga kushanda kuChina.Maererano ne "Montreal Protocol", yechipiri-chizvarwa refrigerant HCFC icharega kushandiswa muna 2030. Kugadziriswa kunoda kuti panosvika 2050, kushandiswa kweHFCs pasi rose kuchadonha ne85%.
Ichi chiitiko chakakosha mufiriji chikamu chekubuda, uye zvakare chinotumira chiratidzo chikuru chezvematongerwo enyika chekuti nharaunda dzepasirese dzakatsunga kumisa kushandiswa kweHFCs.
Panguva imwecheteyo, nekugadzwa kweiyo yepamba "mbiri-kabhoni" tarisiro uye zvishoma nezvishoma kuita yechitatu-chizvarwa refrigerant HFCs control policy, zvinokurumidza kudzidza HCFC, HFCs inotsiva zvinhu uye ane hukama matekinoroji.
Iyo firiji inopinda munguva yepasi GWP kukosha, uye dambudziko rekupisa harigoni kuregererwa!
Kazhinji, kushandiswa kwemafiriji anopfuta ane yakaderera GWP kukosha kutsiva HCFC uye mamwe magasi ane fluorine anoonekwa seanoshanda uye akaderera mutengo mhinduro.Zvisinei, zvidzidzo zvakaratidza kuti mafiriji echinyakare haawanzosangana nezvose zvinodiwa zvemafiriji emangwana kune yakaderera GWP, kuchengeteka, thermodynamic performance uye kwezvakatipoteredza panguva imwe chete.
Mune mamwe mazwi, akawanda akaderera eGWP maitiro anogona kupisa!
Chiyero chenyika "Refrigerant Numbering Method and Safety Classification" GB/T 7778-2017 inokamura huturu hwemafiriji muKirasi A (yakaderera muchetura) uye Kirasi B (yakanyanya chisingaperi chepfu), uye kupisa kunoiswa muKirasi 1 (Hapana kupararira kwemoto. ), Kirasi 2L (zvisina simba zvinogoneka), Kirasi 2 (inogoneka), uye Kirasi 3 (inopfuta uye inoputika).Maererano neGB/T 7778-2017, kuchengetedzwa kwemafiriji kwakakamurwa muzvikamu zvisere, zvinoti: A1, A2L, A2, A3, B1, B2L, B2, uye B3.Pakati pavo, A1 ndiyo yakachengeteka uye B3 ndiyo ine ngozi zvakanyanya.
Maitiro ekushandisa A2L HFO refrigerant zvakachengeteka uye zvinobudirira?
Kunyange zvazvo mhepo yemhepo yemumba, yepakati air conditioners uye zvimwe zvigadzirwa zvefriji zvakaedzwa kushanda pafekitari, kukosha kwekutsvaga kwefiriji yefiriji kunoratidzwa.Nekudaro, mazhinji makuru makuru epakati air-conditioning units uye maindasitiri anotonhora anofanirwa kuzadzwa nefiriji pa-saiti, sezvinoita emumba air-conditioner, midziyo yefiriji, inotonhorera yekuchengetedza, nezvimwewo panguva yekugadzirisa.
Uyezve, nekuda kwemhando dzakasiyana dzeevaporator dzinoshandiswa mune mimwe michina, iyo firiji charge yakasiyana.Mukuwedzera kune nzvimbo yekuchengetedza uye yekuisa, nekuda kwemamiriro mashoma, vashandi vakawanda vanogadzirisa vanobhadhara firiji zvichienderana neruzivo.Mukuwedzera, iyo indasitiri zvakare inotarisisa zvakanyanya kune nyaya yekupisa kwefiriji.
Zvichienderana neizvi, Chemours yakatanga R1234yf, R454A, R454B, R454C uye imwe isingabatike A2L, yakaderera GWP mafiriji, uye yakazvipira kusimudzira dhizaini dhizaini uye yakakurumbira kudzidziswa kwesainzi kugadzirisa njodzi dzekupisa.
Iyo A2L yekuchengetedza nhanho ine hunhu hwekuderera muchetura (A) uye husina simba hwekupisa (2L).Mazhinji maA2L HFO mafiriji ane ese ari maviri epamusoro kuita uye akaderera GWP maitiro, uye akanakira anotsiva ekare chizvarwa cheHFC mafiriji.Zvigadzirwa zveA2L hazvisi kungoshandiswa zvakanyanya mumusika wepasirese, asi makambani mazhinji epamba akasimudzirawo nhanho yekusimudzira uye kuunza iyi rudzi rutsva rwefiriji mumashandisirwo ekugadzira.Semuenzaniso, Johnson Controls inoshandisa Oteon™ XL41 (R-454B) muYork ® YLAA scroll chiller yemusika weEurope;Mutakuri anosarudzawo R-454B (ndiyo Seyayo huru yakaderera-GWP refrigerant, Mutakuri achashandisa R-454B mune yayo tubular yekugara uye yakareruka yekutengesa HVAC zvigadzirwa zvinotengeswa muNorth America kubva 2023.
