Ishishini lezixhobo zekhaya liyicime ngokupheleleyo i-R22 yefriji xa sibala ukwehla
Ngokutsho kweMontreal Protocol, ifriji ye-R22 iye yanqunyanyiswa kumazwe asele iphuhlile kwaye isenokuveliswa kumazwe asakhasayo, kodwa umhla osikiweyo wokuveliswa nokusetyenziswa kwayo ngu-2030.
Ngomhla wama-26 kuJanuwari, ngo-2021, uMphathiswa wezeNdalo kunye nokusiNgqongileyo ukhuphe iSaziso sokuKhupha ngo-2021 iMveliso, ukuSetyenziswa kunye nokuNgeniswa kweMiba yokuNgena kwezinto eziNcincisa iOzone (emva koku kubhekiselwa kuso njengeSaziso). NgokoMthetho weRiphabhlikhi yaBantu baseChina malunga noThintelo kunye noLawulo lokuNgcoliseka koMoya, iMimiselo yoLawulo lweZinto eziNciphisa i-Ozone Layer kunye namanye amalungiselelo afanelekileyo, amashishini angama-20 aya kukhutshwa ngenani lemveliso yeetoni ezingama-292,795 ze-hydrochlorofluorocarbons ( HCFC) ngo-2021, kwaye iiyunithi ze-46 ziya kukhutshwa kunye ne-quota yokusetyenziswa kweetoni ezingama-31,726 ze-hydrochlorofluorocarbons kwi-2021.
Xa kuthelekiswa no-2020, i-quota yemveliso ye-hydrochlorofluorocarbons (HCFCS) equka i-HCFC-22 iya kuhlala ingatshintshi ngo-2021, ngelixa i-quota yokusetyenziswa iya kuncitshiswa kakhulu, isusa ngakumbi i-HCFCS kwishishini le-appliance yase-China.
I-hCFC-equlethe (i-HCFC) i-quota yemveliso iya kukhutshwa kwi-hCFC-141B, i-HCFC-142B, i-HCFC-22, i-HCFC-123, i-HCFC-124 kunye ne-HCFC-133A. Phakathi kwazo, iHCFC-141B yiarhente enogwebu esetyenziswa kwifriji kunye nakwishishini lesifudumezi samanzi. Njengoko inkqubo yogwebu kushishino lwefriji iye yaphuculwa yaya kwi-HFC-245FA + inkqubo ye-cyclopentane yogwebu, kwaye ngomhla we-1 kaJanuwari 2019, imboni yokufudumala yamanzi iye yavala ngokupheleleyo ukusetyenziswa kweHCFC-141B. I-Hcfc-141b isetyenziswe kancinci nangaphantsi kushishino lwezixhobo zasekhaya. Iyonke i-quota yemveliso ye-hCFC-141B ngo-2021 yi-50,878 yeetoni, ayitshintshanga ukusuka kwi-2020.
Xa kuthelekiswa quota imveliso HCFC-22, iyonke ukusetyenziswa quota for hCFC-22 kwishishini air conditioning ekhaya 2021 yi 31,726 iitoni, ukuncipha 3,489 iitoni ukusuka 35,215 iitoni ngo 2020. Oku kunxulumene ngokusondeleyo kwifriji iswitshi kwifriji kwifriji. ishishini lokupholisa umoya ekhaya. Isabelo semarike ye-HCFC-22 ye-air conditioners kwi-air conditioning yasekhaya yayimalunga ne-20% ngo-2019, kwaye lo mlinganiso uya kuqhubeka ukwehla ngo-2020. Ishishini le-air conditioning lasekhaya lase-China lenze impumelelo ephawulekayo ekupheliseni i-HCFC-22.
Isicwangciso solawulo lwe-HCFC-22 yesigaba sokuphuma kwishishini le-air conditioning yasekhaya e-China ukusuka kwi-2021 ukuya kwi-2026 ivunyiwe yiKomiti eLawulayo ye-Multilateral Fund, kwaye izinikele ekupheliseni i-70% yokusetyenziswa kwe-hCFC-22 ngo-2026, leyo ingaphezulu koko kufunwa yishedyuli ye-Montreal Protocol ukuphumeza ukucuthwa kwe-hCFC-22. Siza kwenza igalelo elingakumbi ekuphunyezweni kwe-China yesiVumelwano saseMontreal.
