Kugawa ndi Kuyambitsa kwa Refrigerant ya Madzi Ozizira a Industrial Water Chiller

Kutengera ndi kapangidwe ka mankhwala, mafiriji a mafakitale amatha kugawidwa m'magulu 5: mafiriji a inorganic compound, freon, mafiriji a saturated hydrocarbon, mafiriji a unsaturated hydrocarbon, ndi mafiriji osakaniza a azeotropic. Malinga ndi kuthamanga kwa condensation, mafiriji a chiller amatha kugawidwa m'magulu atatu: mafiriji otentha kwambiri (low-pressure), mafiriji otentha kwambiri (medium-pressure), ndi mafiriji otentha kwambiri (high-pressure). Mafiriji omwe amagwiritsidwa ntchito kwambiri mu mafiriji a mafakitale ndi ammonia, freon, ndi hydrocarbons.

Poyamba pa chitukuko cha mafakitale, R12 ndi R22 zinagwiritsidwa ntchito mu zipangizo zambiri zoziziritsira m'mafakitale. Mphamvu yoziziritsira ya R12 ndi yayikulu kwambiri, ndipo mphamvu zake zogwiritsira ntchito mphamvu nazonso ndi zapamwamba. Koma R12 inawononga kwambiri ozoni ndipo inaletsedwa m'maiko ambiri.

Mafiriji R-134a, R-410a, ndi R-407c, mogwirizana ndi lamulo lapadziko lonse la chitetezo cha chilengedwe, amagwiritsidwa ntchito mu mafiriji a mafakitale a S&A :

(1)R-134a (Tetrafluoroethane) Refrigerant

R-134a ndi refrigerant yodziwika padziko lonse lapansi yomwe imagwiritsidwa ntchito kwambiri m'malo mwa R12. Ili ndi kutentha kwa -26.5°C ndipo imagawana mphamvu zofanana ndi R12. Komabe, mosiyana ndi R12, R-134a siivulaza ozone layer. Chifukwa cha izi, imagwiritsidwa ntchito kwambiri mu ma air conditioner a magalimoto, machitidwe oziziritsira amalonda ndi mafakitale, komanso ngati chopangira thovu popanga zinthu zolimba zotetezera pulasitiki. R-134a ingagwiritsidwenso ntchito popanga ma refrigerant ena osakanikirana, monga R404A ndi R407C. Ntchito yake yayikulu ndi ngati refrigerant ina m'malo mwa R12 mu ma air conditioner a magalimoto ndi firiji.

(2) R-410a Refrigerant

Kapangidwe ka Thupi ndi Mankhwala: Pa kutentha ndi kupanikizika kwabwinobwino, R-410a ndi refrigerant yosakanikirana yopanda chlorine, fluoroalkane, komanso yopanda azeotropic. Ndi mpweya wopanda utoto, wopanikizika womwe umasungidwa m'masilinda achitsulo. Ndi Ozone Depletion Potential (ODP) ya 0, R-410a ndi refrigerant yosawononga chilengedwe yomwe siiwononga ozone layer.

Ntchito Yaikulu: R-410a imagwiritsidwa ntchito makamaka m'malo mwa R22 ndi R502. Imadziwika ndi ukhondo wake, poizoni wochepa, yosayaka, komanso kuzizira bwino kwambiri. Chifukwa chake, imagwiritsidwa ntchito kwambiri m'ma air conditioner apakhomo, ma air conditioner ang'onoang'ono amalonda, ndi ma air conditioner apakhomo.

(3) R-407C Refrigerant

Kapangidwe ka Thupi ndi Mankhwala: R-407C ndi firiji yosakanikirana yopanda chlorine yopanda chlorine pansi pa kutentha ndi kupanikizika kwabwinobwino. Ndi mpweya wopanda utoto, wopanikizika womwe umasungidwa m'masilinda achitsulo. Ili ndi Ozone Depletion Potential (ODP) ya 0, zomwe zimapangitsa kuti ikhale firiji yosamalira chilengedwe yomwe siiwononga ozone layer.

Kugwiritsa Ntchito Kwambiri: Monga m'malo mwa R22, R-407C imadziwika ndi ukhondo wake, poizoni wochepa, kusayaka, komanso kuzizira bwino, komwe kumagwiritsidwa ntchito kwambiri m'ma air conditioner apakhomo komanso m'ma air conditioner ang'onoang'ono komanso apakatikati.

Masiku ano pamene mafakitale akukula, kusunga chilengedwe kwakhala nkhani yofunika kwambiri, zomwe zapangitsa kuti "kusalowerera ndale kwa kaboni" kukhale chinthu chofunika kwambiri. Poyankha izi, kampani yopanga mafiriji a S&A industrial chiller ikuyesetsa kugwiritsa ntchito mafiriji oteteza chilengedwe. Mwa kupititsa patsogolo kugwiritsa ntchito mphamvu moyenera komanso kuchepetsa mpweya woipa, titha kugwira ntchito yolenga "mudzi wapadziko lonse lapansi" wokhala ndi malo achilengedwe oyera.
