R290 refrigerant: inoshandisa nguva yayo yekusimbisa
Muna 2022, R290 refrigerant yakazobuda semutambi wenyeredzi. Mukati mehafu yekutanga yegore, International Electrotechnical Commission (IEC) yakabvuma kuwedzera mari inobvumirwa kuchaja yeR290 mumidziyo yakakwana. Pakati pekupisa kwekupisa kwepombi yekupisa muEurope, R290 yakawana kutarisisa kwakanyanya muchikamu chepombi yekupisa. Pamberi pekambani, zvakare, pakanga paine zvakawanda zvakanaka zviri kuitika, Midea ichitangisa nyika yekutanga R290 air conditioner ine Energy Efficiency Kirasi 1.
Sezvo kushevedzera kwepasirese kwezvirongwa zvakaderera-kabhoni kuri kuwedzera muna 2023, R290 yakagadzirira kukwezva kutarisisa kwakanyanya uye kuunza mikana mitsva yebudiriro.
R290, inozivikanwawo se propane, ndeye yakasikwa hydrocarbon refrigerant inogona kuwanikwa zvakananga kubva kune liquefied petroleum gasi. Kuenzaniswa nemafiriji ekugadzira senge freons, R290's molecular structure haina maatomu eklorini, ichipa iyo Ozone Depletion Potential (ODP) kukosha kwayo zero, nekudaro ichibvisa njodzi yekuderera kweozone layer. Uyezve, kana ichienzaniswa neHFC zvinhu, izvo zvisingakuvadze ozone layer, R290 inozvirumbidza neGlobal Warming Potential (GWP) kukosha pedyo ne zero, kuderedza njodzi ye "greenhouse effect."
Zvisinei nehunhu hwayo husina kujeka maererano neGWP neODP, R290 refrigerant yakatarisana nekukakavadzana kunoramba kuripo nekuda kwekuiswa kwayo seA3 inopfuta mufiriji, ichitadzisa kutorwa kwayo kwakapararira mumisika huru.
Nekudaro, 2022 yakaunza shanduko yakanaka panyaya iyi. Muna Chivabvu 2022, IEC yakazivisa pawebhusaiti yayo yepamutemo kuti kunyorwa kweIEC 60335-2-40 ED7, "Chaizvoizvo zvinodikanwa zvepombi dzekupisa, air-conditioner, uye dehumidifiers," zvakabvumidzwa nemheremhere. Izvi zvinoreva kubvumirana mukati memiyero yeIEC yekuwedzera huwandu hwekuzadza hweR290 uye mamwe mafiriji anopfuta mudzimba mhepo-conditioner, pombi dzekupisa, uye dehumidifiers.
Pakubvunza nezve IEC 60335-2-40 ED7 zviyero, Li Tingxun, anoshamwaridzana purofesa paSun Yat-sen University uye nhengo yeBasa Boka 21, akatsanangura: "Kana uchiverenga huwandu hwekuzadza huwandu hweA2 neA3 mafiriji, IEC 60335 -2-40 ED7 inotangisa kushanduka-shanduka nekufunga nezve chaiwo mamiriro ezvigadzirwa Makambani anogona ikozvino, kuburikidza nekuita matanho ekuchengetedza akadai sekusimudzira chigadzirwa kufema uye kutora dhizaini inotenderera yekuyerera kwemhepo, zvakakodzera kuwedzera huwandu hwekuzadza huwandu hweA2 uye A3 mafiriji, anogona kusvika kumusoro. kusvika 988g.
Uku kusimukira kwakakurudzira kufambira mberi kukuru mukutorwa kweR290 refrigerant muindasitiri yekupisa pombi. Chekutanga, iyo compressor zviyero zvekupisa pombi yemvura inodziya inosanganisirwa zvinodiwa zveR290 refrigerant. Zvadaro, musi wa1 Ndira 2023, nzira itsva dzekuGermany dzekupa zvivakwa zvakasvibira uye dzisingadyi simba dzakatanga kushanda. Homwe iyi ine chinangwa chekubatsira kutsiva masisitimu ekudziya munzvimbo dzakavakwa. Kuti ukwanise kuwana rubatsiro urwu, zvigadzirwa zvepombi yekupisa zvinofanirwa kuve neCoefficient of Performance (COP) pamusoro pe2.7 uye kubhadhariswa mafiriji chaiwo. Parizvino, R290 ndiyo yekutanga firiji yechisikigo inoshandiswa mukugara kupisa pombi michina muEurope. Nekuitwa kwegwaro rerubatsiro, zvigadzirwa zvekupisa zvinoshandisa R290 zvinotarisirwa kuwana kutorwa kwakapararira.
Munguva pfupi yapfuura, hurukuro yehunyanzvi inotarisana neR290 refrigerant uye mapombi ekupisa yakaitwa zvakabudirira. Emerson uye Highly vari vatsigiri vanoshanda veR290 tekinoroji. PaSimposium, mumiriri waEmerson akataura kuti kuwedzera ruzivo rwekambani muR290 tekinoroji yefiriji, vakagadzira nhevedzano yeCopeland scroll R290 compressors, inovhara yakagadziriswa-kumhanya, kusiyanisa-kumhanya, yakachinjika, yakatwasuka, uye yakaderera-ruzha modhi, inopa. akagadzirirwa tekinoroji mhinduro kuzadzisa izvo zvakasiyana zvinodiwa zveEuropean kupisa pombi musika zvikamu. Yakanyanya Magetsi, iine makore anopfuura gumi ehunyanzvi muchikamu chepombi yekupisa, yakafumura akawanda R290-yakatarwa kupisa pombi compressors akagadzirirwa musika weEurope. Zvigadzirwa izvi hazvisi zvehushamwari chete kwezvakatipoteredza asi zvakare zvinozvirumbidza zvakanyanya-yakaderera GWP, yakafara mashandiro, kuvimbika kwepamusoro, uye kushanda nesimba, kugadzirisa zvizere zvinodikanwa zvemusika wepombi yekupisa yekuEurope uye kutsigira shanduko yesimba regirinhi redunhu.
Gunyana 7, 2022, raivewo zuva rakakosha reR290 refrigerant. Pazuva rino, yekutanga pasirese simba rekushandisa giredhi 1 air conditioner inoshandisa R290 refrigerant yakakungurutswa kubva pamutsetse wekugadzira paMidea's Wuhu fekitori, ichipa nzira nyowani yekuti indasitiri izadzise zvinangwa zve "dual carbon". Zvinonzwisiswa kuti APF (Annual Performance Factor) yeMidea ichangoburwa R290 itsva simba rekushandisa giredhi 1 inverter air conditioner yasvika pa5.29, ichipfuura mwero wenyika wegiredhi rekutanga rekushandisa simba idzva ne5.8%. Iwo akateedzana anouya mumhando mbiri: 1HP uye 1.5HP, uye akawanawo yekutanga indasitiri yehutano nehutsanana chitupa.
Zvichakadaro, R290 refrigerant yafambira mberi munzvimbo dzakaita semichina yekuomesa mbatya nekugadzira aizi. Zvinoenderana nedata rakapihwa neChina Household Electrical Appliances Association, iyo ice maker chigadzirwa chikamu chakapotsa chachinja kusvika kuR290 refrigerant mugore rapfuura kana maviri, nekubuda kwepagore kweanosvika miriyoni imwe chete. Saizi yemusika yeR290 yekupisa pombi yekuomesa mbatya yakakwirawo nekukurumidza mumakore achangopfuura, ichiverengera makumi masere muzana muna 2020 nehuwandu hwekugadzira hwemamiriyoni matatu emayuniti.
Muna 2023, inotungamirwa ne "mbiri mbiri kabhoni" zvibodzwa, R290 refrigerant, ine mabhenefiti ayo epasi-kabhoni mabhenefiti, akagadzirira kupenya kunyange kupenya kupfuura kare.
