I-EPA incoma ukuthi amabhizinisi ahlinzeka ngokudla kufanele asebenzise isiqandisi esingu-R290 (esidume kakhulu ngokuthi i-hydrocarbon). Le ndlela ehlukile yemvelo, ephephile, nengenabo ubuthi ayigcini nje ngokuba nobungane endaweni yethu kodwa futhi iyonga imali. Lokhu kusho ukuthi ngeke nje kunciphise ukukhishwa kwezinto ezikhishwayo, kodwa lobu buchwepheshe obusha bunganciphisa izindleko zakho zamandla zizonke kufika ku-28%.

Iziqandisi zika-R290 zivame ukusetshenziswa ezindaweni zokuthengisa njengezitolo, izitolo ezinkulu kanye nezakhiwo zamahhovisi. Kodwa-ke, zisetshenziswa futhi kwezinye izindawo zokuhlala. Isizathu salokhu silula! Iziqandisi zama-R290 zonga imali ngesikhathi esifanayo zivikela imvelo. Lokhu bakwenza ngokusebenzisa ama- hydrocarbon emvelo esikhundleni sama- chlorofluorocarbon (CFCs). Lezi ziqandisi zisavumela izinga elifanayo lamandla okupholisa, kodwa ngeke zilimaze ungqimba lwe-ozone uma zidedelwa emkhathini. Lokhu kubenza babe nobungane kakhulu emhlabeni wethu, yingakho amabhizinisi kufanele acabange ukushintshela kumamodeli efriji angama-R290.

Kungani isiqandisi sika-R290 kuyisinqumo esingcono?

Isiqandisi sika-R290 singenye yezindlela ezintsha ezingasetshenziswa emakethe futhi sinezinzuzo eziningi kunozakwabo. Bhekisisa izizathu ezimbalwa zokuthi kungani le ndlela ingcono kuneziqandisi zekilasi I no-II:

Iyahambisana nemvelo

Isiqandisi sika-R290 asiyingozi kangako emvelweni. Uma ikhishelwa emkhathini, ngeke ibe nomthelela ekuwohlokeni kwe-ozone njengezinye izinketho. Okwenze u-R290 waba indawo ecishe iphelele kwezinye iziqandisi amandla ayo okufudumala komhlaba (i-GWP) kanye ne-zero ozone depletion (ODP). Emashumini eminyaka, u-R134 kanye no-R404 bekuyiziqandisi ezisetshenziswa kakhulu kwezohwebo. Bobabili bane-GWP ephezulu ngendlela emangalisayo, okubenza babe negalelo elikhulu ekufudumaleni komhlaba. Ngakolunye uhlangothi, isiqandisi sika-R290 sinobungane endaweni yethu, okusenza sibe enye indlela ephelele.

Kuqiza kahle

Siphila ezweni lapho ukusimama kubalulekile. Ngakho-ke, imboni yezokudla kumele ibe nesibopho sokugcina impilo yendawo yethu. Isiqandisi sika-R290 singenye isixazululo embonini esingagcini nje ngokulungela iplanethi kodwa futhi ezokonga imali. Inamandla okumunca ukushisa aphezulu ngo-90% kunezandulela zayo. Lokhu kusho ukululama okusheshayo kwezinga lokushisa kanye nokusetshenziswa okuphansi kwamandla. Uzokonga imali ube unokuthula kwengqondo wazi ukuthi awufaki isandla ekukhuphuleni ukushisa komhlaba.

Ukuhambisana

Enye yezinto eyenze isiqandisi sika-R290 saduma kakhulu ukukwazi ukufakwa kumamodeli amaningi amadala ngaphandle kokuwashintsha wonke amasistimu. Lokhu kusho ukuthi kusetshenziswa isikhathi esincane nemali ngenkathi kukuvumela ukuthi usazuza kubuchwepheshe obungcono. Ngaphezu kwalokho, iziqandisi eziwu-R290 zisebenza ngezindlela eziningi ngendlela emangalisayo, futhi zingasetshenziswa ukunika amandla amasistimu okufakwa kweziqandisi ezohwebo ezindaweni zokudlela, ezindaweni zokudlela, namaloli okudla. Sekushiwo lokho, kuyabonakala ukuthi kungani amabhizinisi kufanele ashintshe futhi aqale ukusebenzisa amamodeli efriji angama-R290.

Ingangena ngqo emkhathini.

Enye yezinzuzo ezibalulekile ze-R290 ukuthi ingangena ngqo emkhathini ngaphandle kokudinga ukuphinda ibanjwe futhi igaywe kabusha. Lokhu kuqeda ochwepheshe abaphatha amathangi abizayo kanye nezinsiza ezazisetshenziswa ngokwesiko uma kuseviswa amasistimu amadala kusetshenziswa u-134 noma 404. Ngenxa yalokho, lena isevisi elawuleka kakhulu kubo futhi uzobe ukhokha imali encane kakhulu kunaleyo obuyikhokhela ukunakekela futhi. isevisi.

Ukugaywa kabusha

U-R290 nawo unomlando ofakazelwe wokugaywa kabusha kalula, uwusebenzisele ezinye izinhloso. Lezi yizindaba ezinhle kulabo abafuna ukonga imali futhi basebenzise lokho obekungabhekwa njengomkhiqizo olahlekile.

Ukusimama

U-R290 nawo usethelwe ukuba yizinga elisha lemishini ekhiqizwa esikhathini esizayo. Lokhu kusho ukuthi ngeke kudingeke ukhathazeke ngokwenza ukuthuthukiswa okumba eqolo kanye nokushintshanisa lapho amazinga amasha esekhululiwe futhi asetshenziswa. Ikuvumela ukuthi uthathe isinyathelo esisodwa uye phambili ubheke kusasa eliluhlaza.

Isiphetho

I-R290 iyisiqandisi esimeme kunazo zonke futhi okungenzeka ukuthi uyinketho engcono kakhulu uma kuziwa ekuthengeleni ibhizinisi lakho isiqandisi esithengiswayo. U-R290 uyisiqandisi esizoqinisekisa ukuthi amayunithi akho ahlala isikhathi eside futhi anemininingwane engcono kakhulu yezemvelo.
