Impompo yobushushu i-R152a

Ukuze kuhlaziywe ngamandla aluhlaza kunye namatsha, i-OSB iye yabonisa impompo yobushushu yamva nje eyi-R152a.

Ungabuza, yintoni i-R152a?

Nalu ulwazi olunokuba luncedo kumbono ongcono.

I-R152a isetyenziswa ngokuqhelekileyo njengesixhobo sokuhambisa umoya kwii-aerosols, njenge-arhente ekhupha ugwebu, okanye njengenxalenye yomxube wefriji, nangona kunjalo, ulwahlulo lwayo njengefriji enokutsha kancinane luthintele ukusetyenziswa kwayo kwifriji yemoto kunye neyorhwebo. Nangona kunjalo, irhafu yamva nje yaseSpain yeefriji ze-fluoridated greenhouse refrigerants (ene-GWP enkulu kune-150), kunye nemida ebekwe ngummiselo we-F-Gas ebusweni bokufudumala kwehlabathi, ikhokelele kumdla ohlaziyiweyo kwiifriji ezinokutsha, kunye nokuphezulu kakhulu. iifriji ezinetyhefu ezifana ne-ammonia.

I-Polyurethane okanye i-R152a yihydrocarbon esulungekileyo ye-fluoridate enokwakheka okufana kakhulu ne-R134a. Inomphunga woxinzelelo lwegophe elilingana ne-R134a, ngokutenxa kwe-2K kuphela, kwaye ineempawu zeekhemikhali ezilinganayo, kwaye ke iyahambelana nazo zonke izinto, iinxalenye zesikhenkcisi, iivalvu ze-thermostatic, iicompressors kunye neoyile yokuthambisa.

I-R152a nayo ineempawu eziphezulu ze-thermodynamic ukuya kwi-R134a kunye neFossa. I-coefficient yokudlulisa ubushushu kwisikhenkcisi kwi-evaporators yonyuka malunga ne-20% ngenxa yeempawu ezibonakalayo ezingcono ze-R152a xa kuthelekiswa ne-R134a. Ngenxa ye-viscosity yegesi ephantsi, ukuhla koxinzelelo kwimigca yokufunxa kuya kuncitshiswa ngama-30%. Ubunzima be-molecular ephantsi ye-R152a bunika ukushisa okuphezulu okufihliweyo kwe-evaporation, ukusebenza okuphezulu kwe-volumetric ye-compressor, kunye nokusebenza okungcono kwe-COP yomjikelezo wefriji, kunye neqondo lokushisa eliphezulu lokukhupha malunga ne-10K xa kuthelekiswa ne-R134a.

Kutheni sifuna impompo yobushushu eyi-R152a?

Nanjengoko iluhlaza kwaye iphantsi i-GWP, ikwanendawo yokukhupha amanzi ashushu aphezulu xa ithelekiswa ne-R32.

Kwaye ilungile ukutshintsha i-R134a yempompo yobushushu obuphezulu.

Qhagamshelana nathi ngoku ngolwazi oluthe kratya.
