R-410A vs R-407C m'malo Otentha Ambient

Pali njira zambiri zopangira firiji zomwe zilipo pamsika lero, kuphatikiza zophatikizira zambiri zamafiriji, zomwe cholinga chake ndi kufananiza magwiridwe antchito akale akale ngati R22, kupanga kwake kudakhala kosaloledwa kuyambira Januware chaka chino. Zitsanzo ziwiri zodziwika bwino zamafiriji opangidwa zaka 30 zapitazi zomwe zimagwiritsidwa ntchito m'makampani a HVAC ndi R-410A ndi R-407C. Mafiriji awiriwa nthawi zambiri amagwiritsidwa ntchito mofanana, koma ali ndi kusiyana kwakukulu komwe kuyenera kumveka ndikuganiziridwa posankha pakati pawo.

R-407C

Wopangidwa pophatikiza R-32, R-125, ndi R-134a, R-407C ndi kuphatikizika kwa zeotropic, kutanthauza kuti zinthu zake zimawira pa kutentha kosiyanasiyana. Zinthu zomwe zili ndi R-407C zimagwiritsidwa ntchito kukulitsa mawonekedwe ofunikira, ndi R-32 imathandizira kutentha, R-125 imapereka kutsika kotentha, ndi R-134a kuchepetsa kupanikizika.

Ubwino umodzi wogwiritsa ntchito R-407C pamalo okwera kwambiri ndikuti umagwira ntchito motsika kwambiri. Chotsalira chimodzi chomwe muyenera kudziwa, ndikuyenda kwa R-407C kwa 10 ° F. Chifukwa R-407C ndi chisakanizo cha zeotropic, glide ndi kusiyana kwa kutentha pakati pa nsonga zowiritsa za zinthu zitatuzi. Ngakhale madigiri khumi sangawoneke ngati ochuluka, akhoza kukhala ndi zotsatira zenizeni pazinthu zina za dongosolo.

Kutsetserekaku kungathe kusokoneza kachitidwe ka kachitidwe komwe kumakhala kozungulira kwambiri, chifukwa cha kuyandikira kwa kutentha kwapakati pa nsonga ya condensing ya firiji yomaliza ndi mpweya. Kuonjezera kutentha kwa condensing sikungakhale kokongola, chifukwa cha kutulutsa kwakukulu komwe kumaloledwa ku compressor. Kubwezera izi, zida zina monga ma condenser mafani kapena mafani a condenser ayenera kukhala okulirapo, omwe amabwera ndi zovuta zingapo, makamaka pamtengo.

R-410A

Monga R407C, R-410A ndi kusakaniza kwa zeotropic, ndipo amapangidwa pophatikiza R-32 ndi R-125. Pankhani ya R-410A, komabe, kusiyana kumeneku pakati pa mfundo ziwiri zowira kumakhala kochepa, ndipo refrigerant imatengedwa kuti ndi pafupi ndi azeotropic. Azeotropes ndi zosakaniza zomwe zimakhala ndi malo otentha osasintha, zomwe sizingasinthidwe ndi distillation.

R-410A ndiyotchuka kwambiri pamapulogalamu angapo a HVAC, monga ma condensers. Komabe, pa kutentha kozungulira, kuthamanga kwa R-410A ndikokwera kwambiri kuposa R-407C, zomwe zimapangitsa ena kuganizira zosankha zina za mapulogalamuwa. Ngakhale kuthamanga kwa R-410A pa kutentha kozungulira kumakhala kokwera kwambiri kuposa kwa R-407C, ku Super Radiator Coils, timatha kupanga mayankho omwe ali pa UL omwe amagwiritsa ntchito R-410A mpaka 700 PSIG, ndikupangitsa kuti ikhale yokwanira. refrigerant yotetezeka komanso yothandiza kumadera otentha.

R-410A ndiyotchuka kwambiri pazakudya zoziziritsa kukhosi komanso zamalonda m'misika ingapo, kuphatikiza United States, Europe, ndi madera ena aku Asia. Kudetsa nkhawa kokhudzana ndi kuchuluka kwa magwiridwe antchito m'malo otentha kutha kufotokoza chifukwa chake R-410A siyikuchulukirachulukira m'malo ngati Middle East kapena madera otentha padziko lapansi.
