Kākoʻo ke kulekele kākoʻo o Kelemania i ka hoʻohana ʻana i nā huahana refrigerant maoli, a ʻo R290 ka pauma wela e paʻa i ka mana hoʻomohala nui.

Ma Ianuali 1, 2023, ua hoʻokō ʻia nā hana kākoʻo kālā federal hou no nā hale ʻōmaʻomaʻo a me ka ikaika o ka ikehu ma Kelemania. Hoʻolālā ʻia kēia kālā e hāʻawi i nā haʻawina no ka hoʻomaikaʻi ʻana i nā ʻōnaehana hoʻomehana i loko o ka hale hale. Pumehana Pono nā huahana kūpono no kēia haʻawina he COP waiwai o 2.7 a ʻoi aʻe a hoʻopiha ʻia me nā mea hana maoli.

E like me ka helu ʻana o ka German Federal Office of Economics and Export Control, ʻo kēia haʻawina he 40% o ke kumukūʻai no ke kūʻai ʻana o nā mea kūʻai aku i nā huahana paila wela, me ka 25% kōkua kumu, kahi kālā 5% no ka hoʻohana ʻana i nā mea hana maoli, a me kahi haʻawina 5% no nā kumu wela o ka wai honua a i ʻole ka wai. Eia naʻe, ʻaʻole hui pū nā haʻawina ʻelua no nā mea hana maoli a me nā kumu wela. Hōʻike kēia inā inā Ka Pumehana ʻAʻole hoʻohana ka huahana i kūʻai ʻia e nā mea kūʻai aku i nā mea hana kūlohelohe a ʻo ka kumu wela ʻaʻole ka wai o luna a i ʻole ka wai, ʻaʻole hiki iā lākou ke loaʻa kēia haʻawina i hāʻawi ʻia e ke aupuni Kelemania.

I kēia manawa, ʻo R290 ka mea hana maoli maoli i hoʻopiha ʻia i loko o nā lako wela wela ma ʻEulopa. Me ka hoʻokō ʻana i kēia kulekele kōkua, e hoʻolaha ʻia nā huahana pauma wela e hoʻohana ana iā R290 ma kahi ākea nui.

ʻO ka ʻoiaʻiʻo, mai ka wā i puka mai ai ka pilikia o ka ikehu, ua piʻi nui ka noi no nā huahana pump wela ma Kelemania a me ka mākeke ʻEulopa. Wahi a ka German Heat Pump Industry Association he 230,000 mau paila wela hou i hoʻokomo ʻia ma 2022 a me 350,000 i 2023, e hōʻike ana i ka piʻi ʻana o ka makahiki he 52%. Hōʻike ka hōʻike i hoʻokuʻu ʻia e ka International Energy Agency (IEA) i ka hapa mua o 2022, ua pālua ka kūʻai ʻana o nā pauma wela ma kekahi mau lālā o ka EU ma mua o ka manawa like ma 2021. Manaʻo ʻia ʻo ke kūʻai ʻana o nā pauma wela i kēlā me kēia makahiki ma nā ʻāina EU e manaʻo ʻia e hiki i 7 miliona mau ʻāpana i 2023, a ʻo ka honua holoʻokoʻa i hoʻokomo ʻia i ka mana o nā paila wela i ka 2.6 biliona hola. I kēlā manawa, hiki i ka 20% ka nui o nā paila wela i ka ʻōnaehana hoʻomehana honua.

ʻO kēia pūʻulu o ka ʻikepili mai ka IEA ʻaʻole i hoʻokomo wale i ka hilinaʻi i ka hoʻomohala ʻana i ka mākeke pahū wela akā pū kekahi, me ka hoʻonui ʻana i ka nui o ka mākeke holoʻokoʻa o nā pā wela, ʻo ka noi ʻana o R290 i nā pā wela e apo i nā manawa hoʻomohala nui.

Ua hāʻawi hoʻi nā kūlana i ka hoʻonui ʻana i ka noi ʻana o R290 i ka ʻoihana pahū wela. I Mei 2022, ua ʻōlelo ka IEC ma kāna pūnaewele mana i ʻae ʻia ka hoʻolālā o IEC 60335-2-40 ED7 "Nā Manaʻo Kūikawā no nā Pump Heat, Air Conditioners a me Dehumidifiers". ʻO ia ke ʻano o ka hoʻonui ʻana i ka palena o ka nui o ka hoʻopiha ʻana o R290 a me nā mea hoʻoheheʻe ahi ʻē aʻe i loko o nā ea ea hale, nā paila wela a me nā dehumidifiers ua hoʻoholo lokahi ʻia i ka maʻamau IEC. Ma Mei 21, 2022, ua alakaʻi ka Subcommittee on Major Components for Household Appliances o ka National Technical Committee for Household Appliance Standardization i ka loiloi o ka "Hermetically Sealed Motor-Compressor for Household and Similar Heat Pump Water Heaters". Ua paʻi ʻia ke kiko piha no ka noi ʻana i nā manaʻo o kēia maʻamau a aia i kēia manawa i ka pae ʻae. Hoʻomaopopo ʻia ʻo ka hoʻololi nui loa i kēia hoʻoponopono maʻamau ʻo ka hoʻoponopono ʻana i ke ʻano o ka noi, hoʻohui i ka refrigerant R290, etc.

ʻAʻole paʻakikī ke ʻike inā ma ka pae kulekele a i ʻole ka pae maʻamau, ʻo ka hoʻolaha ʻana i ka noi ʻana o R290 i nā huahana pahū wela ua lilo i mea hiki ʻole. Ke alakaʻi ʻia e kēia, ua hoʻonohonoho ikaika nā ʻoihana nui iā lākou iho i kēia mākeke.

Ma ka 2022 Mostra Convegno Expocomfort (MCE) ma Milan, Italia, ua hōʻike nui ʻia ʻo HEEALARX INDSTRY LIMITED i kahi ʻano o nā huahana pauma wela o ka hale me ka hoʻohana ʻana iā R290, e huki ana i ka manaʻo kiʻekiʻe mai nā mea hoʻomohala ʻoihana. Ua hōʻike ʻia mai ka makahiki 2020, ua hoʻomaka ʻo HEEALARX e hoʻomohala ikaika i nā huahana mīkini hoʻomehana papahele me ka hoʻohana ʻana iā R290 e like me ka refrigerant.

I ka 2022 CHILLVENTA ma Kelemānia, e hoʻokō i ka koi wela wela ma ka ʻāina Nordic, ua hana ʻo GMCC&Welling i kahi hopena wela R290. ʻO kēia hoʻonā ʻana he mahana hoʻoheheʻe wale nō -35 ℃, kahi lākiō hoʻopaʻa a hiki i 17, a me ka mahana condensation kiʻekiʻe a hiki i 83 ℃. Ma o ka ʻenehana hou e hoʻomaikaʻi ai i ka mīkini, peʻa a me ka circulation pump, lawe mai ia i ka hoʻomaikaʻi ʻana i ka hana ma ke ʻano o ka pono, hilinaʻi, a me ka hoʻohaʻahaʻa leo.

No ka hoʻohui ʻana i ka mākeke Australia, ua hoʻolauna ʻo Phnix i ka R290 ea puna wela wela nā huahana Everest series, e hui pū ana i nā hiʻohiʻona maikaʻi loa a e hōʻike ana i ka ʻenehana pahū wela kiʻekiʻe loa o Phnix i kēia manawa. Hoʻokomo ʻia ka ErP (Energy-related Products) o nā huahana Phnix Everst series a hiki i A +++, a hiki i ka SCOP (Seasonal Coefficient of Performance) i 5.20.

Eia nō naʻe, ma Kina, mai ka hapa ʻelua o 2022, ua hoʻokuʻu ʻia nā ʻāpana like ʻole a me nā kūlanakauhale i nā hoʻolālā hoʻokō carbon peak, e hoʻoikaika ana i ka hoʻolaha ʻana i nā huahana e like me nā pā wela. Hāʻawi kēia i kahi hoʻoikaika hou i ka noi ʻana o R290 i ka pā wela wela o ka home. I ka manawa like, ke hoʻonui wikiwiki nei ʻo R290 i kāna ʻāina i nā kīhāpai home e like me nā ea ea hale, dehumidifiers, nā mea hana hau, a me nā mea maloʻo wela.

Ua hiki mai ka puna o R290.
