Indasitiri yemidziyo yemumba yakabvisa zvachose R22 firiji mukuverenga
Sekureva kweMontreal Protocol, firiji yeR22 yakamiswa munyika dzakabudirira uye inogona kugadzirwa munyika dzichiri kusimukira, asi nguva yekupedzisira yekugadzira nekushandisa ndeye 2030.
Musi waNdira 26, 2021, Ministry of Ecology and Environment yakapa Chiziviso pamusoro peKuburitswa kwe2021 Kugadzira, Kushandisa uye Kupinza Quotas yeOzone Depleting Substances (inozozivikanwa seChiziviso). Zvinoenderana neMutemo wePeople's Republic of China pamusoro peKudzivirira uye Kudzora Kusvibiswa Kwemhepo, Mitemo paKutungamira Kwezvinhu Zvinobvisa Ozone Layer uye zvimwe zvipi zvakakodzera, mabhizinesi makumi maviri achapihwa chikamu chekugadzira che292,795 matani ehydrochlorofluorocarbons ( HCFC) muna 2021, uye zvikamu makumi mana nematanhatu zvichapihwa chikamu chekushandisa che31,726 matani ehydrochlorofluorocarbons muna 2021.
Zvichienzaniswa na2020, chikamu chekugadzira chehydrochlorofluorocarbons (HCFCS) kusanganisira HCFC-22 chicharamba chisina kuchinjika muna 2021, nepo chiyero chekushandisa chichadzikiswa zvakanyanya, zvichiwedzera kubvisa HCFCS muindasitiri yeChina yemidziyo yemumba.
HCFC-containing (HCFC) chikamu chekugadzira chichapihwa hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 neHCFC-133A. Pakati pavo, HCFC-141B inopupuma mumiririri inoshandiswa mufiriji uye indasitiri yemvura yekupisa. Sezvo iyo foaming system muindasitiri yefiriji yakakwidziridzwa kuita HFC-245FA + cyclopentane foaming system, uye muna Ndira 1, 2019, indasitiri yekupisa yemvura yakarambidza zvachose kushandiswa kweHCFC-141B. Hcfc-141b yakashandiswa zvishoma nezvishoma muindasitiri yemidziyo yemumba. HCFC-141B inokwana 50,878 matani, isina kuchinjwa kubva muna 2020.
Zvichienzaniswa nehuwandu hwekugadzirwa kweHCFC-22, huwandu hwese hwekushandisa hwehCFC-22 muindasitiri yemhepo inofefetera mudzimba muna 2021 i31,726 matani, kuderera kwe3,489 matani kubva pa35,215 matani muna 2020. Izvi zvine hukama nefiriji switch mufiriji mu iyo imba yekufefetera mhepo indasitiri. Mugove wemusika weHCFC-22 air conditioners muindasitiri yemhepo inofefetera pamba yaive ingangoita 20% muna 2019, uye chikamu ichi chicharamba chichidzikira muna 2020. Indasitiri yeChina yemhepo inofefetera yakaita budiriro inoshamisa mukubvisa HCFC-22.
Iyo HCFC-22 phase-out management strategy yeDomestic air conditioning indasitiri muChina kubva 2021 kusvika 2026 yakabvumidzwa ne Executive Committee ye Multilateral Fund, uye yakazvipira kubvisa makumi manomwe muzana ehCFC-22 kushandiswa panosvika 2026, iyo. yakawandisa kupfuura inodiwa neMontreal Protocol hurongwa kuti uwane kuderedzwa kwehCFC-22. Tichaita zvimwe zvakawanda mukushandiswa kweChina kweMontreal Protocol.
