Makampani opanga zida zapanyumba adachotseratu firiji ya R22 powerengera
Malinga ndi Montreal Protocol, refrigerant ya R22 yayimitsidwa m'maiko otukuka ndipo imatha kupangidwabe m'maiko omwe akutukuka kumene, koma tsiku lomaliza kupanga ndikugwiritsa ntchito ndi 2030.
Pa Januware 26, 2021, Unduna wa Zachilengedwe ndi Zachilengedwe udapereka Chidziwitso Chokhudza Kutulutsidwa kwa 2021 Kupanga, Kugwiritsa Ntchito ndi Kulowetsa Zinthu za Ozone Depleting Substances (zomwe zimatchedwa Chidziwitso). Malinga ndi Lamulo la People's Republic of China pa Kupewa ndi Kuwongolera Kuwonongeka kwa Air, Malamulo pa Kasamalidwe ka Zinthu Zomwe Zimachepetsa Ozone Layer ndi zina zofunikira, mabizinesi 20 adzapatsidwa gawo lopanga matani 292,795 a hydrochlorofluorocarbons ( HCFC) mu 2021, ndipo magawo 46 adzapatsidwa kuchuluka kwa matani 31,726 a hydrochlorofluorocarbons mu 2021.
Poyerekeza ndi 2020, kuchuluka kwa ma hydrochlorofluorocarbons (HCFCS) kuphatikiza HCFC-22 sikudzasintha mu 2021, pomwe kuchuluka kwa ntchito kudzachepetsedwa kwambiri, ndikuchotsanso HCFCS mumakampani aku China opangira zida zamagetsi.
Gawo lopangira hCFC-containing (HCFC) lidzaperekedwa kwa hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 ndi HCFC-133A. Pakati pawo, HCFC-141B ndi chopangira thovu chomwe chimagwiritsidwa ntchito mufiriji ndi mafakitale otenthetsera madzi. Pamene makina opangira thovu m'makampani a firiji asinthidwa kukhala HFC-245FA + cyclopentane foaming system, ndipo pa Januware 1, 2019, makampani otenthetsera madzi aletsa kugwiritsa ntchito HCFC-141B. Hcfc-141b yagwiritsidwa ntchito pang'onopang'ono m'makampani opanga zida zapakhomo. Chiwerengero chonse cha hCFC-141B mu 2021 ndi matani 50,878, osasinthika kuchokera mu 2020.
Poyerekeza ndi kuchuluka kwa kupanga kwa HCFC-22, kuchuluka kwa kugwiritsidwa ntchito kwa hCFC-22 mumakampani opanga mpweya wapanyumba mu 2021 ndi matani 31,726, kuchepa kwa matani 3,489 kuchokera ku matani 35,215 mu 2020. Izi zikugwirizana kwambiri ndi kusintha kwa firiji mufiriji mu makampani opanga mpweya wapanyumba. Gawo lamsika la ma air conditioner a HCFC-22 pamakampani opanga mpweya wapanyumba linali pafupifupi 20% mu 2019, ndipo gawoli lipitilira kutsika mu 2020. Makampani opanga mpweya waku China apanga bwino kwambiri pakuchotsa HCFC-22.
HCFC-22 phase-out management strategy for the Domestic air conditioning industry ku China kuyambira 2021 mpaka 2026 yavomerezedwa ndi Executive Committee of the Multilateral Fund, ndipo yadzipereka kuthetsa 70% ya hCFC-22 kugwiritsa ntchito pofika 2026, yomwe. ndi zochuluka kuposa zomwe zimafunidwa ndi ndondomeko ya Montreal Protocol kuti akwaniritse kuchepetsa hCFC-22. Tidzathandiza kwambiri kuti dziko la China likhazikitse ndondomeko ya Montreal Protocol.
