Chifukwa chiyani Pampu Yotentha ya R290 Idzakhala Yamtsogolo Pamsika wa EU?

Pa Okutobala 5, 2023, European Commission ndi European Parliament inagwirizana mwakachetechete pa "kuchepetsa zinthu zomwe zimayambitsa kutentha kwa dziko ndi kuwononga ozone layer."

Zomwe zili mumgwirizanowu, kumbali imodzi, zidamaliza zokambirana zam'mbuyomu pa F-gas Act, ndiko kuti, pofika 2050, kugwiritsa ntchito ma HFCs (hydrofluorocarbons) kudzathetsedwa. Kumbali inayi, mgwirizanowu ukutsimikiziranso mgwirizano wosakhazikika womwe unachitika mu June 2023 pazinthu zomwe zimachotsa gawo la Ozone (ODS). Izi zikutanthauza kuti kukhazikitsidwa kwa mgwirizano wanthawi yayitali kupangitsa kuti ma HFC aziyang'anizana ndi maulamuliro okhwima ku Europe.

Chimodzi mwazochititsa chidwi kwambiri ndi kuletsa zida zazing'ono zapakhomo zapanyumba, mgwirizanowu ukunena kuti pofika chaka cha 2027, kugwiritsa ntchito mphamvu yaing'ono (mphamvu zosakwana 12KW) monobloc kutentha mpope ndi ma air conditioners omwe ali ndi mtengo wa GWP wamkulu kuposa 150HFC adzakhala oletsedwa kwathunthu, ndipo zidzathetsedwa mu 2032. Izi zikusonyeza kuti Mapampu Otentha pogwiritsa ntchito HFC-134a, HFC-404A, R410A, R22, R32 ndi mafiriji ena apamwamba a GWP adzakumana ndi kuchotsedwa ndikutuluka pamsika ku Europe.

Kodi mukugwiritsabe ntchito zopopera zotenthetsera zosawononga zachilengedwe kuti mutenthetse nyumba yanu?

Tsopano tili ndi yankho lomwe lingathe kuthetsa kwathunthu kutentha, kuzizira ndi mavuto a chilengedwe, osati kungopangitsa moyo wanu kukhala womasuka, komanso kuteteza dziko lathu lokhalo, lomwe ndilo kugwiritsa ntchito R290 ngati firiji.

Ubwino wa Pampu Yotentha ya R290

·Kuchepa kwa GWP:

R290 ndi firiji ya hydrocarbon (HC) yokhala ndi GWP ya 3HFC yokha. Nambala yodabwitsayi ya GWP ndi yeniyeni ndipo ili pansi pa ma 150HFC omwe amafunikira pakuletsa. Mtengo wotsika woterewu umatanthauza kuti zotsatira zake pa kutentha kwa kutentha (ie mpweya wotuluka mwachindunji) ndizosavomerezeka ndipo, motero, sizochepa ndipo zikhoza kuonedwa ngati njira yothetsera nthawi yaitali.

·Kutentha Kwambiri:

Nthawi zambiri, pampu yotenthetsera mpweya imatha kutentha mpaka 40-60 ° C, koma pampu yotenthetsera mpweya yogwiritsa ntchito R290 ngati firiji imatha kupereka nyumba kutentha kwa 75 ° C pomwe kutentha kwakunja kuli -15 ° C.

·Kusunga Mphamvu:

Kafukufuku wambiri wasonyeza kuti kutentha kobisika kwa evaporation ya propane pafupifupi kuwirikiza kawiri kwa mafiriji ambiri a HFC, zomwe zikutanthauza kuti pamlingo womwewo wa refrigerant mass flow flow, R290 idzakhala ndi kuzizira / kutentha kwakukulu. Zikutanthauza kuti kugwiritsa ntchito R290 ngati firiji kungabweretse phindu lalikulu lachuma kubanja.

Kukhazikika Kwamitengo:

Mtengo wa mafiriji okhala ndi zigawo zoyera za HFO ukhoza kusiyana kwambiri kutengera zinthu, ndipo kusiyana kwamitengo kumeneku kumatha kukhala kofunikira kwambiri pakagwiritsidwa ntchito zambiri. M'malo mwake, poyang'ana pamitengo ya R290 m'zaka zitatu zapitazi, titha kuwona kuti kusinthasintha kwamitengo kwa R290 ndikocheperako, kotero kuti mtengo wokhazikika ulinso mwayi wa R290.

Kuthekera Kwa Msika Wamtsogolo wa EU Pa Pampu Yotentha ya R290

Monga tafotokozera pamwambapa, ndi GWP ya 3 yokha, R290 ndi firiji yomwe imagwirizana bwino ndi malamulo atsopano a EU. Kuonjezera apo, pampu yotentha ya R290 ndi yogwirizana kwambiri ndi chilengedwe kusiyana ndi mapampu ambiri otentha omwe amagwiritsa ntchito mafiriji ena panthawi imodzimodziyo mtengo siwosiyana kwambiri. Ndipo chifukwa R290 ili ndi magwiridwe antchito achilengedwe komanso magwiridwe antchito abwino a thermodynamic, Ndiye ikafika kutentha komweko, R290 imatha kukupulumutsirani ndalama.

Choncho, R290 Heat Pump idzakhala chinthu chodziwika kwambiri pamsika wa EU mtsogolomu.
