qaboojiyaha R290: waxay keenaysaa waqtigeeda ugu weyn

Sannadkii 2022, qaboojiye R290 ayaa ugu dambayntii u soo baxay sidii xiddig-qaade. Intii lagu jiray qeybtii hore ee sanadka, Guddiga Caalamiga ah ee Electrotechnical (IEC) waxay ogolaatay in la ballaariyo xadka la oggol yahay ee R290 qalab dhamaystiran. Iyada oo ay ku jirto kor u kaca kuleyliyaha bamka kulaylka ee Yurub, R290 ayaa dareen weyn ka yeeshay qaybta matoorka kulaylka. Dhinaca hore ee shirkadda, sidoo kale, waxaa jiray horumarro wanaagsan oo badan, iyadoo Midea ay bilawday qaboojiyaha R290 ee ugu horreeya adduunka oo leh Heerka Waxtarka Tamarta ee 1.

Iyada oo baaqa caalamiga ah ee dadaallada kaarboon-yar-yar uu sii kordhayo 2023, R290 waxay diyaar u tahay inay soo jiidato xitaa dareen weyn oo ay keento fursado cusub oo horumarineed.

R290, sidoo kale loo yaqaan propane, waa qaboojiye hydrocarbon dabiiciga ah kaas oo si toos ah looga heli karo gaaska dareeraha ah. Marka la barbar dhigo qaboojiyaha synthetic sida freons, qaab-dhismeedka molecular ee R290 kuma jiraan atamka koloriin, taasoo ka dhigaysa eber-qiimihii ay yarayn lahayd lakabka ozone. Intaa waxaa dheer, marka la barbar dhigo walxaha HFC, kuwaas oo aan sidoo kale waxyeello u geysan lakabka ozone, R290 waxay ku faantaa qiimaha kuleylka caalamiga ah (GWP) oo ku dhow eber, yareynta khatarta "saameynta cagaaran."

In kasta oo ay jirto aqoonsigeeda aan la aqbali karin marka loo eego GWP iyo ODP, qaboojiyaha R290 waxa uu la kulmay muran joogto ah sababta oo ah waxa loo kala saaray sidii qaboojiye ololaya oo A3 ah, taas oo caqabad ku ah korsashada baahsan ee suuqyada caadiga ah.

Si kastaba ha ahaatee, 2022 waxay keentay isbeddel wanaagsan oo arrintan ku saabsan. Bishii Maajo 2022, IEC waxay ku dhawaaqday degelkeeda rasmiga ah in qabyo-qoraalka IEC 60335-2-40 ED7, "shuruudaha gaarka ah ee matoorada kulaylka, qaboojiyeyaasha, iyo qoyaan-saareyaasha," ayaa si wadajir ah loo ansixiyay. Tani waxay muujinaysaa heshiis ka dhex jira heerarka IEC si loo kordhiyo cadadka buuxinta R290 iyo qaboojiyeyaasha kale ee guban kara qaboojiyaha guriga, bambooyin kulaylka, iyo qoyaan-saareyaasha.

Markii wax laga weyddiiyey heerarka IEC 60335-2-40 ED7, Li Tingxun, oo ah borofisar ku-xigeenka Jaamacadda Sun Yat-sen iyo xubin ka tirsan Kooxda Shaqada 21, wuxuu sharraxay: "Marka la xisaabinayo qaddarka ugu badan ee buuxinta qaboojiyaha A2 iyo A3, IEC 60335 -2-40 ED7 waxay soo bandhigaysaa dabacsanaan badan iyadoo la tixgelinayo shuruudaha dhabta ah ee alaabooyinka shirkaduhu hadda waxay awoodaan, iyada oo loo marayo hirgelinta tillaabooyinka amniga sida kor u qaadida hawo-mareenka alaabta iyo qaadashada naqshadaha wareegga hawada, si habboon u kordhinta qiyaasta ugu badan ee buuxinta A2 iyo A3 qaboojiyaha, oo suurtagal ah in la gaaro. ilaa 988 g.

Horumarkani waxa uu huriyay horumar la taaban karo oo ku saabsan qaadashada qaboojiyaha R290 ee warshadaha bamka kulaylka. Marka hore, heerarka kombaresarada ee kuleyliyaha biyaha matoorka kulaylka ayaa lagu daray shuruudaha qaboojiyaha R290. Intaa ka dib, Janaayo 1, 2023, tillaabooyinka maalgelinta federaalka cusub ee Jarmalka ee dhismayaasha cagaaran iyo tamarta waxtarka leh ayaa dhaqan galay. Sanduuqan ujeedadiisu waxay tahay in lagu kabo beddelka nidaamyada kuleyliyaha ee deegaannada la dhisay. Si aad ugu qalanto kabitaannadan, alaabada matoorka kulaylku waa inay lahaadaan isku-xidhka Waxqabadka (COP) oo ka sarreeya 2.7 oo lagu dallaco qaboojiyeyaasha dabiiciga ah. Hadda, R290 waa qaboojiyaha aasaasiga ah ee dabiiciga ah ee loo isticmaalo qalabka bamka kulaylka ee la deggan yahay ee Yurub. Dhaqangelinta siyaasaddan kabidda, badeecooyinka kuleyliyaha ee isticmaalaya R290 ayaa la filayaa inay helaan korsasho baahsan.

Dhawaan, dood-cilmiyeed farsamo oo diiradda lagu saarayay qaboojiyaha R290 iyo matoorada kulaylka ayaa si guul leh loo qabtay. Emerson iyo Highly waa taageerayaasha firfircoon ee R290. Dood-cilmiyeedka, wakiilka Emerson wuxuu sheegay in ka faa'iidaysiga waayo-aragnimada ballaadhan ee shirkadda ee tignoolajiyada qaboojiyaha R290, ay soo saareen taxane ah Copeland rogroup R290 kombaresarada, daboolaya xawaaraha go'an, variable-xawaaraha, siman, toosan, iyo moodooyinka qaylada hoose, oo bixiya xalal farsamo oo loo habeeyey si loo daboolo baahiyaha kala duwan ee qaybaha suuqa bamka kulaylka ee Yurub. Highly Electric, oo leh in ka badan toban sano oo khibrad u leh qaybta matoorka kulaylka, ayaa daaha ka qaaday kombaresarada bamka kulaylka badan ee R290 oo loogu talagalay suuqa Yurub. Alaabooyinkani kaliya maaha kuwo deegaanka saaxiibtinimo leh, laakiin sidoo kale waxay ku faanaan GWP aadka u hooseeya, kala duwanaanshiyaha hawlgalka ee ballaaran, isku halaynta sare, iyo hufnaanta, si guud wax uga qabta baahiyaha suuqa bamka kulaylka Yurub isla markaana taageeraya kala-guurka tamarta cagaaran ee gobolka.

Sebtembar 7, 2022, sidoo kale waxay ahayd maalin muhiim u ah qaboojiyaha R290. Maalintan, heerkii ugu horreeyay ee wax ku oolnimada tamarta cusub ee adduunka 1 qaboojiyaha iyadoo la adeegsanayo qaboojiyaha R290 ayaa ka duushay khadka wax soo saarka ee warshadda Wuhu ee Midea, taasoo bixisa hab cusub oo warshadaha si ay u gaaraan yoolalka "dual carbon". Waxaa la fahamsan yahay in APF (Factor Performance Annual) ee Midea's cusub ee R290 tayada tamarta cusub ee fasalka 1 inverter hawo uu gaaray 5.29, dhaaftay heerka qaranka ee waxtarka tamarta cusub fasalka 1 by 5.8%. Taxanuhu wuxuu u socdaa laba nooc: 1HP iyo 1.5HP, wuxuuna sidoo kale helay shahaadada caafimaadka iyo nadaafadda ee ugu horreysa ee warshadaha.

Dhanka kale, qaboojiyaha R290 ayaa horumar ka sameeyay meelaha ay ka mid yihiin qalajiyaasha dharka iyo kuwa sameeya barafka. Marka loo eego xogta ay bixisay Ururka Qalabka Korontada ee Guriga ee Shiinaha, qaybta wax soo saarka barafka ayaa si buuxda ugu gudubtay qaboojiyaha R290 sannadkii ama labadii sano ee la soo dhaafay, iyada oo wax soo saar sanadle ah oo ku dhow 1.5 milyan unug. Baaxadda suuqa ee R290 mishiinnada dharka kuleyliyaha ayaa sidoo kale si xawli ah kor ugu kacay sannadihii la soo dhaafay, taasoo ka dhigan 80% sanadka 2020 iyada oo mugga wax soo saarkeedu yahay 3 milyan oo unug.

Sannadka 2023, oo ay hagaan himilooyinka "dual carbon", qaboojiyaha R290, oo leh faa'iidooyinka kaarboon-yar ee dabiiciga ah, ayaa diyaar u ah inuu ka iftiimiyo sidii hore.
