Kuwongolera Kutentha Kwambiri kwa Laser Systems ndi Industrial Applications Kuyambira 2002
Chilankhulo
Kutengera ndi kapangidwe ka mankhwala, mafiriji oziziritsa m'mafakitale atha kugawidwa m'magulu asanu: mafiriji a inorganic compound, freon, saturated hydrocarbon refrigerants, unsaturated hydrocarbon refrigerants, ndi azeotropic mix refrigerants. Malingana ndi kupanikizika kwa condensing, mafiriji ozizira amatha kugawidwa m'magulu atatu: mafiriji otentha kwambiri (otsika kwambiri), mafiriji apakati (pakatikati) ndi mafiriji otsika kwambiri (otsika kwambiri). Mafiriji omwe amagwiritsidwa ntchito kwambiri m'mafakitale ozizira ndi ammonia, freon, ndi ma hydrocarbon.
Kumayambiriro kwa chitukuko cha mafakitale, R12 ndi R22 zidagwiritsidwa ntchito pazida zambiri zamafiriji. Kutha kwa kuziziritsa kwa R12 ndikokulirapo, ndipo mphamvu zake ndizokwera kwambiri. Koma R12 inawononga kwambiri mpweya wa ozoni ndipo inaletsedwa m’mayiko ambiri.
Refrigerants R-134a, R-410a, ndi R-407c, mogwirizana ndi zofunikira zapadziko lonse zoteteza chilengedwe, amagwiritsidwa ntchito S&A mafakitale ozizira:
(1)R-134a (Tetrafluoroethane) Refrigerant
R-134a ndi firiji yodziwika padziko lonse lapansi yomwe imagwiritsidwa ntchito ngati m'malo mwa R12. Ili ndi kutentha kwa mpweya wa -26.5 ° C ndipo imagawana zinthu zofanana ndi thermodynamic ndi R12. Komabe, mosiyana ndi R12, R-134a siili yovulaza ku ozone layer. Chifukwa cha izi, amagwiritsidwa ntchito kwambiri muzowongolera mpweya wamagalimoto, mafiriji amalonda ndi mafakitale, komanso ngati chopangira thovu popanga zida zolimba za pulasitiki. R-134a itha kugwiritsidwanso ntchito kupanga mafiriji ena osakanikirana, monga R404A ndi R407C. Ntchito yake yayikulu ndi njira ina yopangira firiji kupita ku R12 muzowongolera mpweya wamagalimoto ndi firiji.
(2) R-410a Firiji
Katundu Wakuthupi ndi Mankhwala: Pa kutentha kwabwino ndi kupanikizika, R-410a ndi chlorine-free, fluoroalkane, non-azeotropic mix refrigerant. Ndi gasi wopanda mtundu, wosakanizidwa wa liquefied yemwe amasungidwa mu masilinda achitsulo. Ndi Ozone Depletion Potential (ODP) ya 0, R-410a ndi firiji yogwirizana ndi chilengedwe yomwe siwononga ozoni layer.
Ntchito Yaikulu: R-410a imagwiritsidwa ntchito makamaka ngati m'malo mwa R22 ndi R502. Amadziwika ndi ukhondo wake, kawopsedwe kakang'ono, kusayaka, komanso kuzizira kwambiri. Chotsatira chake, chimagwiritsidwa ntchito kwambiri m'ma air conditioners apakhomo, ma air conditioners ang'onoang'ono amalonda, ndi ma air conditioners apanyumba.
(3) R-407C Firiji
Katundu Wakuthupi ndi Mankhwala: R-407C ndi firiji yopanda chlorine ya fluoroalkane yopanda azeotropic pansi pa kutentha ndi kupanikizika. Ndi gasi wopanda mtundu, wosakanizidwa wa liquefied yemwe amasungidwa mu masilinda achitsulo. Ili ndi Mphamvu ya Ozone Depletion Potential (ODP) ya 0, ndikupangitsa kuti ikhalenso firiji yogwirizana ndi chilengedwe yomwe siwononga ozoni.
Ntchito Yaikulu: Monga m'malo mwa R22, R-407C imadziwika ndi ukhondo wake, kawopsedwe kakang'ono, kusayaka, komanso magwiridwe antchito abwino kwambiri oziziritsa, omwe amagwiritsidwa ntchito kwambiri m'ma air conditioners apakhomo ndi zoziziritsa kukhosi zazing'ono ndi zapakati.
Masiku ano kukula kwa mafakitale, kuteteza chilengedwe kwakhala chinthu chofunikira kwambiri, zomwe zimapangitsa kuti "kusalowerera ndale" kukhala chinthu chofunikira kwambiri. Potengera izi, S&A mafakitale chiller wopanga akuyesetsa kugwiritsa ntchito mafiriji ochezeka ndi zachilengedwe. Polimbikitsa kugwiritsa ntchito mphamvu zamagetsi komanso kuchepetsa kutulutsa mpweya, titha kuyesetsa kupanga "mudzi wapadziko lonse" wodziwika ndi malo abwino kwambiri achilengedwe.

TEYU S&A Chiller idakhazikitsidwa mu 2002 ndi zaka 22 zopanga zoziziritsa kukhosi, ndipo tsopano amadziwika kuti ndi mpainiya wozizira waukadaulo komanso mnzake wodalirika pamakampani a laser.
