Imboni yemishini yasendlini isiqede ngokuphelele isiqandisi esingu-R22 ngesikhathi sibala
Ngokwe-Montreal Protocol, isiqandisi sika-R22 simisiwe emazweni athuthukile futhi sisengakhiqizwa emazweni asathuthuka, kodwa umnqamulajuqu wokukhiqizwa nokusetshenziswa kwawo ngu-2030.
Ngomhla zingama-26 kuMasingana, 2021, uMnyango Wezemvelo Nemvelo ukhiphe Isaziso Sokukhishwa Kwezilinganiso Zokukhiqiza, Ukusetshenziswa Nokungenisa Kwango-2021 Zezinto Eziqeda I-Ozone (ngemuva kwalokhu okubizwa ngokuthi Isaziso). Ngokomthetho wePeople's Republic of China on the Prevention and Control of Air Pollution, Imithethonqubo Yokuphathwa Kwezinto Eqeda I-Ozone Layer nezinye izinhlinzeko ezifanele, amabhizinisi angama-20 azonikezwa isilinganiso sokukhiqiza amathani angama-292,795 ama-hydrochlorofluorocarbons ( HCFC) ngo-2021, futhi amayunithi angama-46 azokhishwa ngesabelo sokusetshenziswa samathani angama-31,726 wama-hydrochlorofluorocarbons ngo-2021.
Uma kuqhathaniswa no-2020, isilinganiso sokukhiqiza sama-hydrochlorofluorocarbons (HCFCS) okuhlanganisa i-HCFC-22 sizohlala singashintshile ngo-2021, kuyilapho isilinganiso sokusetshenziswa sizoncishiswa kakhulu, kuphinde kuqedwe i-HCFCS embonini yemishini yasekhaya yase-China.
Isabelo sokukhiqiza esiqukethe i-hCFC (HCFC) sizokhishelwa i-hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 kanye ne-HCFC-133A. Phakathi kwazo, i-HCFC-141B iyi-ejenti enegwebu esetshenziswa embonini yesiqandisi kanye ne-heater yamanzi. Njengoba uhlelo olunamagwebu embonini yesiqandisi seluthuthukisiwe lwaba yi-HFC-245FA + cyclopentane foaming system, futhi ngoJanuwari 1, 2019, imboni ye-heater yamanzi ikuvimbele ngokuphelele ukusetshenziswa kwe-HCFC-141B. I-Hcfc-141b isetshenziswe kancane kancane embonini yezinto zikagesi zasendlini. Isamba esiphelele sokukhiqiza se-hCFC-141B ngo-2021 singamathani angu-50,878, asishintshile kusukela ngo-2020.
Uma kuqhathaniswa nesabelo sokukhiqiza se-HCFC-22, inani eliphelele lokusetshenziswa kwe-hCFC-22 embonini ye-air conditioning yasekhaya ngo-2021 singamathani angu-31,726, ukwehla ngamathani angu-3,489 kusukela kumathani angu-35,215 ngo-2020. Lokhu kuhlobene eduze neswishi yesiqandisi ku-2020. imboni ye-air conditioning yasendlini. Isabelo semakethe se-HCFC-22 air conditioning embonini ye-air conditioning yasekhaya sasicishe sibe ngama-20% ngo-2019, futhi lesi silinganiso sizoqhubeka nokwehla ngo-2020. Imboni yasekhaya yase-China yenze impumelelo emangalisayo ekuqedeni i-HCFC-22.
Isu lokulawula ukuphuma kwe-HCFC-22 lemboni ye-Domestic air conditioning e-China kusukela ngo-2021 kuya ku-2026 ligunyazwe yiKomidi Eliphethe Le-Multilateral Fund, futhi lizibophezele ekuqedeni ukusetshenziswa kuka-70% kwe-hCFC-22 ngo-2026, okuyinto ingaphezu kwalokho okudingwa uhlelo lwe-Montreal Protocol ukuze kuzuzwe ukuncipha kwe-hCFC-22. Sizokwenza amagalelo athe xaxa ekuqalisweni kwe-China kweSivumelwano sase-Montreal.
