Mfundo zothandizira ku Germany zimathandizira kugwiritsa ntchito zinthu zopangira furiji zachilengedwe, ndipo mapampu otentha a R290 ali ndi kuthekera kwakukulu kwachitukuko.

Pa Januware 1, 2023, njira zatsopano zothandizira thumba la federal panyumba zobiriwira komanso zosagwiritsa ntchito mphamvu ku Germany zidayamba kugwira ntchito. Thumbali lapangidwa kuti lipereke ndalama zothandizira kukweza makina otenthetsera m'malo omanga. Zopangira zopopera kutentha zomwe zikuyenera kulandira thandizoli ziyenera kukhala ndi mtengo wa COP wa 2.7 kapena kupitilira apo ndikudzazidwa ndi zinthu zachilengedwe zogwirira ntchito.

Malinga ndi mawerengedwe a German Federal Office of Economics and Export Control, subsidy iyi imapanga 40% ya mtengo wa ogula kugula zinthu zopopera kutentha, kuphatikizapo 25% Basic subsidy, 5% subsidy yogwiritsa ntchito zinthu zachilengedwe. , ndi thandizo la 5% la malo otentha okhala ndi madzi apamtunda kapena zimbudzi. Komabe, zithandizo ziwiri zazinthu zogwirira ntchito zachilengedwe ndi magwero a kutentha sizowonjezera. Izi zikutanthauza kuti ngati chopopera chotenthetsera chomwe chimagulidwa ndi ogula sichigwiritsa ntchito zinthu zachilengedwe zogwirira ntchito ndipo gwero la kutentha si madzi apamtunda kapena zimbudzi, sangathe kupeza chithandizo choperekedwa ndi boma la Germany.

Pakadali pano, chinthu chachikulu chogwirira ntchito zachilengedwe chodzazidwa ndi zida zopopera zotentha zogona ku Europe ndi R290. Ndi kukhazikitsidwa kwa lamulo la subsidy iyi, zinthu zopopera kutentha zogwiritsa ntchito R290 zidzakwezedwa pamlingo waukulu.

M'malo mwake, kuyambira pomwe vuto lamagetsi lidayamba, kufunikira kwa zinthu zopopera kutentha ku Germany komanso msika waku Europe kwakwera kwambiri. Bungwe la Germany Heat Pump Industry Association likuneneratu kuti mapampu atsopano 230,000 adayikidwa mu 2022 ndi 350,000 mu 2023, zomwe zikuyimira kuwonjezeka kwa chaka ndi 52%. Lipoti lotulutsidwa ndi International Energy Agency (IEA) limasonyeza kuti mu theka loyamba la 2022, malonda a mapampu otentha m'mayiko ena omwe ali m'bungwe la EU adawirikiza kawiri poyerekeza ndi nthawi yomweyi mu 2021. Zikuyembekezeka kuti malonda a pachaka a mapampu otentha Mayiko a EU akuyembekezeka kufika mayunitsi 7 miliyoni mu 2023, ndipo mphamvu zonse zomwe zidayikidwa padziko lonse lapansi za mapampu otentha zikuyembekezeka kufika maola 2.6 biliyoni a kilowatt. Pofika nthawi imeneyo, kuchuluka kwa mapampu otentha m'nyumba yotentha yapadziko lonse lapansi kudzafika 20%.

Deta iyi yochokera ku IEA sikuti imangowonjezera chidaliro pakukula kwa msika wa mpope wa kutentha komanso, ndikuwonjezeka kwa msika wonse wa mapampu otentha, kugwiritsa ntchito R290 pamapampu otentha kudzakumbatira mwayi waukulu wachitukuko.

Miyezo yaperekanso mphamvu pakugwiritsa ntchito R290 pamakampani opopera kutentha. Mu Meyi 2022, IEC idanena patsamba lake lovomerezeka kuti zolemba za IEC 60335-2-40 ED7 "Zofunika Zapadera Pamapampu Otentha, Zoziziritsa M'mlengalenga ndi Dehumidifiers" zidavomerezedwa mogwirizana. Izi zikutanthauza kuti kuwonjezeka kwa malire a kudzaza kwa R290 ndi mafiriji ena oyaka moto m'ma air conditioners apanyumba, mapampu otentha ndi dehumidifiers zadutsa mogwirizana muyeso wa IEC. Pa Meyi 21, 2022, Komiti Yaikulu Yoyang'anira Zida Zazida Zapakhomo ya National Technical Committee for Household Appliance Standardization idatsogolera kukonzanso kwa "Hermetically Sealed Motor-Compressor for Household and Similar Heat Pump Water Heaters". Zolemba zonse zofunsira malingaliro a muyezowu zasindikizidwa ndipo pano zili pagawo lovomerezeka. Zimamveka kuti kusintha kwakukulu pakusinthidwa kokhazikikaku ndikuwunikanso kuchuluka kwa ntchito, kuwonjezera R290 refrigerant, ndi zina zambiri.

Sizovuta kuona kuti kaya pamlingo wa ndondomeko kapena mulingo wokhazikika, kulimbikitsa kugwiritsa ntchito R290 muzinthu zopopera kutentha kwakhala njira yosapeŵeka. Motsogozedwa ndi izi, mabizinesi akuluakulu nawonso akhazikika pamsika uno.

Pamsonkhano wa 2022 Mostra Convegno Expocomfort (MCE) ku Milan, Italy, HEEALARX INDSTRY LIMITED adawonetsa motsogola zinthu zingapo zapanyumba zogwiritsa ntchito R290, zomwe zimakopa chidwi chambiri kuchokera kumakampani ambiri. Akuti kuyambira 2020, HEEALARX yayamba kupanga mwamphamvu makina otenthetsera pampu pansi pogwiritsa ntchito R290 ngati firiji.

Pa 2022 CHILLVENTA ku Germany, kukumana ndi kutentha mpope Kutentha amafuna m'dera Nordic, GMCC & Welling analenga R290 kutentha mpope wonse yankho. Njirayi imakhala ndi kutentha kwa mpweya wokha -35 ℃, chiŵerengero cha psinjika mpaka 17, ndi kutentha kwakukulu kwa condensation mpaka 83 ℃. Kudzera muukadaulo waukadaulo wokhathamiritsa ma mota, mafani ndi pampu yozungulira, zimabweretsa kusintha kwa magwiridwe antchito, kudalirika, komanso kuchepetsa phokoso.

Kuti aphatikizire mumsika waku Australia, Phnix yakhazikitsa zida zamtundu wa R290 mpweya wotenthetsera Everest, zomwe zimaphatikiza zinthu zingapo zabwino kwambiri ndikuyimira ukadaulo wapamwamba kwambiri wapampu ya Phnix pakadali pano. Zimadziwitsidwa kuti ErP (Zokhudzana ndi Mphamvu) za mndandanda wa Phnix Everst zimafika ku A +++, ndipo SCOP (Seasonal Coefficient of Performance) ikufika pa 5.20.

Pakadali pano, ku China, kuyambira theka lachiwiri la 2022, zigawo ndi mizinda yosiyanasiyana yatulutsa motsatizana ndondomeko zoyendetsera mpweya, zonse zikugogomezera kukwezedwa kwa zinthu monga mapampu otentha. Izi zipereka chilimbikitso china pakugwiritsa ntchito R290 m'munda wampope yotentha yapanyumba. Nthawi yomweyo, R290 ikukulitsanso gawo lake mwachangu m'minda ya zida zapanyumba monga zoziziritsira mpweya wapanyumba, zoziziritsa kukhosi, zopangira ayezi, ndi zowumitsa pampu kutentha.

Kasupe wa R290 wafika.
