Kodi pali kusiyana kotani pakati pa R22 ndi R410A refrigerant?

1. R410A firiji amafunika kugwiritsa ntchito mafuta opanga firiji (POE), chifukwa mafuta a POE ali ndi hygroscopicity kwambiri ndipo amatha hydrolysis. Poyerekeza ndi R22, dongosolo R410A lili zofunika kwambiri kuti okhutira chinyezi.

2. Potengera kuchuluka kwa perfusion, pambuyo poti chosinthira kutentha chachepetsedwa, kuchuluka kwa mafuta a R410A kumachepetsa pafupifupi 20% mpaka 30% poyerekeza ndi dongosolo la R22. Kutentha kosintha kwa dongosolo la R410A ndikokulirapo kuposa kwa R22, kutentha kwa kutentha kumakhala kokwera, ndipo chosinthira kutentha kumatha kupangidwiratu.

3. R410A ndi firiji yosakanikirana ndi HFC-32 (R32) ndi HFC-125. R410A ili ndi zofunikira kwambiri pamachubu zamkuwa, pomwe R22 itha kugwiritsa ntchito machubu wamba amkuwa; kuthamanga kwa R410A ndi 50 ~ 70% kuposa ya R22, pafupifupi nthawi 1.6.

4. R410A ndi ya poizoni wochepa, ilibe kuyaka kwa kuyaka, ndipo sichiwononga wosanjikiza wa ozoni. R22 imapha komanso kuwononga ozoni wosanjikiza; Dongosolo R410A ali bwino kuzirala, ngati R22 100% mphamvu kuzirala, R410A ndi 147% mphamvu kuzirala;

5. Ngakhale R410A sichiwononga ozone wosanjikiza, mpweya wowonjezera kutentha womwe umatulutsa, mpweya wake wowonjezera kutentha umapitilira R22. Chifukwa chake, R410A sindiyo njira yabwino kwambiri yoziziritsira zachilengedwe yazogulitsa zaku China. Haha, anzanu onse omwe amati R410A ndi firiji yosasamala zachilengedwe, mutha kupumula.

6. R410A imakhala ndi mpweya wokwanira kuposa R22, chifukwa chake kutuluka kwa nthunzi kwa R410A kuli pafupifupi 30% pang’onopang’ono kuposa R22; R410A imasungunuka kwambiri kuposa R22. Zotsalirazo zikuyandama pa R410A, zimatha kuzungulira bwino.

Nkhani zina zofunika kuzisamalira

1. R410A mapaipi amkuwa ayenera kugwiritsira ntchito mapaipi apadera amkuwa osakanikirana kwambiri, ndipo magawo ake agwiritsenso ntchito mapaipi amkuwa apadera. Ma machubu amkuwa a R410a atha kugwiritsidwa ntchito m’malo mwa machubu amkuwa a R22, koma ndizosatheka kutengera machubu amkuwa a R410a ndi machubu wamba amkuwa a R22.

2. R410A ikagawika firiji yatsopano, sayenera kusokonezedwa ndi chitoliro cholumikizira ndi firiji yomwe imagwiritsidwa ntchito mu ma R conditioner a R22.

3. R410A mpweya wofewetsa umafuna kukwera kwakukulu. Musatengere thukuta mu chitoliro cholumikizira, ndipo musasakanize zosafunika zina zosasungunuka. Mu Buku ili la Refrigeration, tikulimbikitsidwa kuti dongosololi litulutsidwe kuti lisapangitse kuipitsa kosakanikirana kwa mafiriji.

4. Pakukonza, ngati firiji idadulidwa, fyuluta imayenera kusinthidwa, ndipo firiji sayenera kuwonetsedwa kwa mpweya kwa mphindi zopitilira zisanu.

5. R410A firiji iyenera kusungidwa m’malo ochepera 30 ° C. Ngati yasungidwa m’malo opitilira 30 ° C, iyenera kusungidwa m’malo ochepera 30 ° C kwa maola opitirira 24 isanagwiritsidwe ntchito.

6. Valavu ya njira zinayi yomwe imagwiritsidwa ntchito mu dongosolo la R410A ili ndi zofunikira zowoneka bwino zaukhondo, pomwe valavu ya njira zinayi yomwe imagwiritsidwa ntchito mu dongosolo la R22 ilibe zofunikira paukhondo.

7. Zovuta zamagetsi zogwirira ntchito zotsekedwa ndizosiyana, kugwiritsa ntchito refrigerant R22 ndi 3.0MPa, ndikugwiritsa ntchito refrigerant R410A ndi 4.3MPa. R22 ndi cholumikizira mkuwa cha 3.0 MPa, ndipo R410A ndi cholumikizira chosapanga dzimbiri cha 4.3 MPa.

8. Mphamvu yamagetsi yamagetsi ndiyosiyana, makina a R22 nthawi zambiri amasankha 3.0 / 2.4MPa, R410A dongosolo limasankha 4.2 / 3.6MPa.

9. Pansi pa voliyumu yamagetsi, kuchuluka kwa kusuntha kulikonse (1cc) kwa R22 kompresa kompresa kuli pafupifupi 175W, ndipo kutha kwa kusuntha kulikonse (1cc) kwa matenthedwe a R410A system compressor pafupifupi 245W, omwe ndi 65% mpaka 70% ya dongosolo la R22. za.

10. Chipinda chakunja cha mafiriji chimadziwika ndi mtundu wa refrigerant yomwe zida zimagwiritsidwira ntchito, ndi firiji iti yomwe imagwiritsidwira ntchito firiji yotchulidwa. R22 siyingasinthidwe mwachindunji ndi R410a.
