Jambulani kukula kwa msika wapampopi waku Europe mu 2021
Kugulitsa pampu ya kutentha kwakula ndi 34% ku Europe - kuchuluka kwanthawi zonse, ziwerengero zofalitsidwa lero ndi European Heat Pump Association ziwulula.Magawo a 2.18 miliyoni a mapampu otentha adagulitsidwa m'mayiko a 21 * - pafupifupi 560,000 kuposa 2020. Izi zimabweretsa chiwerengero chonse cha mapampu otentha omwe anaikidwa ku EU ku 16.98 miliyoni, akuphimba pafupifupi 14% ya msika wotentha.
Mapampu otentha omwe akhazikitsidwa ku EU amapewa matani opitilira 44 miliyoni a CO2 - ochulukirapo pang'ono kuposa mpweya wapachaka wa Ireland - ndi gawo lotenthetsera lomwe limapanga pafupifupi 1000 Mt yonse.
Thomas Nowak, mlembi wamkulu wa European Heat Pump Association anati:
"Kukula kwa gawo lopopera kutentha mu 2021 ndi gawo limodzi lakusintha kwakukulu pakutentha kokhazikika ku Europe.Tili ndi zovuta zitatu: Mfundo za EU zikuyendetsa maboma kuti awononge ntchito yomanga, kudumpha patsogolo paukadaulo wapampopi yotentha, komanso mliri wa Covid womwe wathandiza nzika zambiri kuzindikira kuti ziyenera kukweza nyumba zawo.
Pothirirapo ndemanga pazochitika zapadziko lonse lapansi, Rana Adib, Executive Director wa renewable energy body REN21 adati:
"Mukayang'ana gawo la kutentha ndi kuziziritsa komwe kumagwiritsa ntchito mphamvu yopitilira 50% ya mphamvu zonse, mphamvu zongowonjezedwanso zimangotenga 11% yokha. Vuto laposachedwa lamagetsi likuwonetsa kufunika kokhala ndi ndalama zotsika mtengo, zodalirika, komanso zowonjezera- makina opangira mphamvu omwe ndi pomwe mapampu otentha amagwira ntchito yofunika kwambiri ku Europe ndi kupitirira apo. "
Ku Europe chaka chatha, misika yonse yapampopi yapadziko lonse idakula kwambiri, ngakhale ena amagulitsa kwambiri kuposa ena.Kupindula kwamphamvu kwambiri kwa mapampu otentha otentha kunapezeka ku Poland (kuwonjezeka kwa 87%), Ireland (+69%), Italy (+63%), Slovakia (+42%) Norway, France (iliyonse + 36%) ndi Germany (+ 28%).
87% ya kuchuluka kwa msika waku Europe idagulitsidwa m'maiko khumi okha (France, Italy, Germany, Spain, Sweden, Finland, Norway, Poland, Denmark ndi Netherlands).Mayiko atatu apamwamba, France, Germany, Italy ndi theka la malonda apachaka.
Misika isanu yayikulu kwambiri yaku Europe yopopera kutentha malinga ndi magawo omwe adagulitsidwa (mapampu otentha ndi magawo amadzi otentha) mu 2021 anali France (mayunitsi 537,000 ogulitsidwa, + 36%), Italy (382,000, + 64%), Germany (177,000, + 26% ), Spain (148,000, +16%), ndi Sweden (135,000, +19%).
Kuwonjezeka kwakukulu kokwanira poyerekeza ndi ziwerengero za 2020 kudakwaniritsidwa ku Italy (mayunitsi 150,000 ogulitsidwa kwambiri kuposa 2020 - zotsatira zomveka bwino za chithandizo chamayiko), France (+143,000), Poland (+43,000), Germany (+37,000) ndi Norway. (+33,000).
"Ziwerengerozi zitha kuchulukirachulukira chaka chamawa pomwe REPowerEU ikukonzekera kuchotsa gasi waku Russia ndipo zolinga zake zofunitsitsa zopangira mapampu otentha ziyamba. Tikuwona kuperewera kwa magawo, komabe, komwe kungachepetse kuchuluka.Apa tikuwona kufunikira kwa dongosolo la EU pampu yotenthetsera kutentha, kuwonetsetsa kuti kukula bwino ndikupewa zopinga za HR, "anawonjezera Jozefien Vanbecelaere, Mtsogoleri wa EU Affairs ku European Heat Pump Association.
Kupulumutsa Kwakukulu Posintha kupita ku HVAC yokhazikika ndi Madzi ku Maofesi a Mumbai
Kutembenuka kwa makina ozizirira oziziritsidwa ndi mpweya wapakati munyumba zamaofesi apamwamba ku Mumbai kukhala zoziziritsa kuziziritsa madzi kumatha kubweretsa ndalama zokwana INR 1.75 biliyoni (pafupifupi $ 22.9 miliyoni) pamabilu amagetsi pachaka, JLL India, yemwe amapereka ntchito zogulitsa nyumba, adatero. pa May 4. Wothandizira katunduyo adati malo aofesi a Mumbai a Giredi A pakadali pano ali pa 144 miliyoni ft2 (pafupifupi 13.4 miliyoni m2), pomwe 42% yokha amagwiritsa ntchito makina otenthetsera, mpweya wabwino, ndi zowongolera mpweya (HVAC).
Kupulumutsa mphamvu ndi dongosolo logwira ntchito la HVAC kumapereka njira zothetsera nthawi yayitali zochepetsera mphamvu zamagetsi panyumba yamalonda, JLL India idatero mu lipoti lake "Njira yokhazikika kudzera munjira za HVAC"."M'kati mwa 60 miliyoni ft2 (pafupifupi 5.6 miliyoni m2) ya maofesi okhala ndi machitidwe a HVAC apakati, 33 miliyoni ft2 (pafupifupi 3.1 miliyoni m2) amagwiritsa ntchito mpweya woziziritsa madzi womwe umakhala wopatsa mphamvu kuposa makina oziziritsa mpweya.Chifukwa chogwiritsa ntchito makina ozizirira oziziritsa madziwa, gawo la ofesi ya Mumbai limatha kupulumutsa mphamvu zokwana 185 miliyoni kWh pachaka, kumasulira kuchepetsedwa kwa matani 14.8 miliyoni a mpweya wa CO2, "adatero JLL India."Kutembenuka kwa ndalama zokwana 27 miliyoni ft2 (pafupifupi 2.5 miliyoni m2) zoziziritsa mpweya za HVAC zapakati kuti zikhale zoziziritsidwa ndi madzi kumapereka mwayi wopulumutsa 152 miliyoni kWh ya mphamvu pachaka.Izi zitha kupangitsa kuti kuchepetsedwa kwa INR 1.75 biliyoni mubilu yamagetsi pachaka ndi matani 120,000 a mpweya wotulutsa mpweya, "adawonjezera.
Zomwe zimatengera ndalama zoyendetsera kukweza kotereku zitha kukhala zolepheretsa eni ake ambiri ndi osunga ndalama, koma zopindulitsa zowoneka bwino pamitengo yoyendetsera ntchito ndi phindu la chilengedwe komanso kupulumutsa mphamvu zimaposa zopinga zomwe zachitika posachedwa.
Msika wa VRF waku China Uli Ndi Mphamvu Zina Zowonjezera Kukula
Msika waku China wosinthika wa refrigerant flow (VRF) wakumana ndi zaka zopitilira 20 zakutukuka kosalekeza.Mu 2021, idaposa mayunitsi 1.33 miliyoni, kuwerengera 64% ya msika wapadziko lonse wa VRF, malinga ndi kuyerekezera kwa JARN.Kukula kwa msika wapachaka kudafika 20.7% mu 2021, ndi 25.4% ya mini-VRFs ndi 12.7% ya VRFs.
Ngakhale kukula kosalekeza, msika wa VRF ukadali ndi kuthekera kokulirakulira.Malinga ndi aircon.com, msika waku China wa ma VRF waposa RMB 450 biliyoni (pafupifupi US$ 67 biliyoni) pakadali pano, zomwe zimaposa kukhazikitsidwa kwatsopano komanso kukulitsa kukula kwatsopano - kufunanso kukonzanso.
Kuti agwiritse ntchito mwayi wambiri pamsika waukuluwu, opanga ayenera kupanga ma VRF omwe ali ndi mphamvu zambiri, athanzi, omasuka, anzeru, ndi zina zambiri.
Kugwiritsa ntchito mphamvu kwamphamvu ndi mawu ofunikira kwambiri pazandale zaku China zosagwirizana ndi kaboni.M'mizinda yayikulu yomwe idapangidwa koyambirira, pali nyumba zambiri zamaofesi ndi nyumba zapagulu zomwe zidayika ma VRF omwe akuyandikira kumapeto kwa moyo wawo tsopano.M'nyumba zoterezi, ma VRF akale amafunika kusinthidwa ndi ma VRF atsopano omwe ali ndi mphamvu zowonjezera mphamvu.
Munthawi ya mliri wapambuyo pa mliri, ma VRF omwe ali ndi ntchito monga kuyeretsa mpweya, kutsekereza, komanso mpweya wabwino akopa chidwi chochulukirapo.Makamaka, panthawi ya mliri, zipatala zambiri zomwe zakonzedwanso pang'onopang'ono ndikukonzedwa kuti zikwaniritse kufunikira kwakukulu kwa malo otetezeka omwe amafunikira ma VRF okhala ndi ntchito zabwino.
Kuphatikiza pa kukweza kwazinthu, opanga ayenera kukweza mautumiki awo a VRF.Ayenera kupanga njira zonse zotsekereza kasamalidwe kazinthu zogulitsa kale, zogulitsa, ndi zogulitsa pambuyo pake, zomwe zitha kupititsa patsogolo kupikisana kwamtundu wawo.
Mothandizidwa ndi kuthekera kotereku, opanga ma VRF aku China akweza ndalama kuti alimbikitse luso lawo lopanga.
