Iphampu yokushisa engu-R152a

Ukuze kuthuthukiswe amandla aluhlaza namandla amasha, i-OSB yethule iphampu yokushisa yakamuva engu-R152a.

Ungase ubuze, yini i-R152a?

Nalu ulwazi olungaba usizo ngombono ongcono.

I-R152a ivame ukusetshenziswa njengesiphepheli kuma-aerosol, njenge-ejenti ekhihliza amagwebu, noma njengengxenye yezingxube zesiqandisi, nokho, ukuhlukaniswa kwayo njengesiqandisi esivutha kancane kukhawule ukusetshenziswa kwayo eziqandisini zezimoto nezohwebo. Kodwa-ke, intela yakamuva yaseSpain yamafriji abamba ukushisa ane-fluoridated (ene-GWP engaphezu kuka-150), kanye nemikhawulo ebekwe umthetho we-F-Gas lapho ubhekene nokufudumala kwembulunga yonke, iholele ekubeni nentshisekelo evuselelwe eziqandisini ezivuthayo, ngisho nangaphezulu. iziqandisi ezinobuthi njenge-ammonia.

I-polyurethane noma i-R152a iyi-hydrocarbon ehlanzekile eyi-fluoridate enziwe ngendlela efana kakhulu ne-R134a. Inejika lomfutho we-vapor elilingana no-R134a, elinokuchezuka okungu-2K kuphela, futhi linezici zamakhemikhali ezifanayo, futhi ngenxa yalokho lihambisana nazo zonke izinto zokwakha, izakhi zesiqandisi, amavalvu e-thermostatic, ama-compressor namafutha okugcoba.

I-R152a futhi inezici ze-thermodynamic eziphakeme kune-R134a ne-Fossa. I-coefficient yokudlulisa ukushisa yesiqandisi kuma-evaporator ikhuphuka cishe ngo-20% ngenxa yezakhiwo ezingcono ezibonakalayo ezingu-R152a uma kuqhathaniswa no-R134a. Ngenxa ye-viscosity yegesi ephansi, ukwehla kwengcindezi emigqeni yokudonsa kuzoncishiswa ngo-30%. Isisindo samangqamuzana esiphansi esingu-R152a siwunikeza ukushisa okucashile okuhwamuka, ukusebenza kahle kwevolumu ephezulu ye-compressor, kanye nokusebenza okungcono kwe-COP komjikelezo wesiqandisi, nezinga lokushisa eliphezulu lokukhipha cishe elingu-10K uma liqhathaniswa ne-R134a.

Kungani sidinga iphampu yokushisa engu-R152a?

Njengoba iluhlaza futhi iphansi i-GWP, futhi inendawo yokukhipha amanzi ashisayo ephakeme uma iqhathaniswa no-R32.

Futhi kuhle ukufaka esikhundleni sephampu yethempele ephezulu engu-R134a.

Xhumana nathi njengamanje ukuze uthole ulwazi olwengeziwe.
