Ukuhlukaniswa kanye Nesingeniso Kwe-Industrial Water Chiller Refrigerant

Ngokusekelwe ekwakhiweni kwamakhemikhali, iziqandisi ze-industrial chiller zingahlukaniswa ngezigaba ezi-5: iziqandisi ze-inorganic compound, i-freon, iziqandisi ze-hydrocarbon ezigcwele, iziqandisi ze-hydrocarbon ezingagcwele, kanye neziqandisi ze-azeotropic mixed. Ngokusho kwengcindezi yokunciphisa, iziqandisi ze-chiller zingahlukaniswa ngezigaba ezi-3: iziqandisi ze-high-temperature (low-pressure), iziqandisi ze-medium-temperature (medium-pressure), kanye neziqandisi ze-low-temperature (high-pressure). Iziqandisi ezisetshenziswa kakhulu kuma-industrial chiller yi-ammonia, i-freon, kanye nama-hydrocarbon.

Esigabeni sokuqala sokuthuthukiswa kwezimboni, i-R12 kanye ne-R22 kwakusetshenziswa emishinini eminingi yokuqandisa yezimboni. Amandla okupholisa e-R12 makhulu kakhulu, futhi ukusebenza kahle kwamandla nakho kuphezulu. Kodwa i-R12 yabangela umonakalo omkhulu ongqimbeni lwe-ozone futhi yayivinjelwe emazweni amaningi.

Iziqandisi R-134a, R-410a, kanye no-R-407c, ngokuhambisana nemfuneko yokuvikelwa kwemvelo yamazwe ngamazwe, zisetshenziswa kuma -S&A industrial chillers :

(1)R-134a (Tetrafluoroethane) Isiqandisi

I-R-134a iyi-refrigerant eyaziwayo emhlabeni wonke evame ukusetshenziswa esikhundleni se-R12. Inezinga lokushisa lokuhwamuka elingu--26.5°C futhi inezakhiwo ezifanayo ze-thermodynamic ne-R12. Kodwa-ke, ngokungafani ne-R12, i-R-134a ayilimazi ungqimba lwe-ozone. Ngenxa yalokhu, isetshenziswa kakhulu kuma-air conditioner ezimoto, izinhlelo zokuqandisa zezentengiselwano nezezimboni, kanye ne-ejenti yokugqwala yokukhiqiza izinto zokuvikela zepulasitiki eqinile. I-R-134a ingasetshenziswa futhi ukudala ezinye iziqandisi ezixubile, njenge-R404A kanye ne-R407C. Ukusetshenziswa kwayo okuyinhloko kuyindlela ehlukile yokuqandisa kune-R12 kuma-air conditioner ezimoto kanye nokuqandisa esiqandisini.

(2) I-R-410a Isiqandisi

Izakhiwo Zomzimba Nezamakhemikhali: Ngaphansi kokushisa nokucindezela okuvamile, i-R-410a iyi-refrigerant exubile engenayo i-chlorine, i-fluoroalkane, ne-non-azeotropic. Iyigesi engenambala, ecindezelwe encibilikisiwe egcinwa kumasilinda ensimbi. Njengoba ine-Ozone Depletion Potential (ODP) engu-0, i-R-410a iyi-refrigerant enobungane nemvelo engalimazi ungqimba lwe-ozone.

Ukusetshenziswa Okuyinhloko: I-R-410a isetshenziswa kakhulu esikhundleni se-R22 kanye ne-R502. Yaziwa ngokuhlanzeka kwayo, ubuthi obuphansi, ukungashi, kanye nokusebenza kahle kokupholisa. Ngenxa yalokho, isetshenziswa kabanzi kuma-air conditioner asekhaya, kuma-air conditioner amancane ebhizinisi, kanye nama-air conditioner aphakathi asekhaya.

(3) Isiqandisi se-R-407C

Izakhiwo Zomzimba Nezamakhemikhali: I-R-407C iyi-refrigerant exubile ye-fluoroalkane non-azeotropic engenayo i-chlorine ngaphansi kokushisa okuvamile kanye nengcindezi. Iyigesi engenambala, ecindezelwe encibilikisiwe egcinwa kumasilinda ensimbi. Ine-Ozone Depletion Potential (ODP) engu-0, okwenza futhi ibe yi-refrigerant enobungani nemvelo engalimazi ungqimba lwe-ozone.

Ukusetshenziswa Okuyinhloko: Njengendlela yokufaka esikhundleni se-R22, i-R-407C ibonakala ngokuhlanzeka kwayo, ubuthi obuphansi, ukungashi, kanye nokusebenza kahle kokupholisa, okusetshenziswa kakhulu kuma-air conditioner asekhaya kanye nama-air conditioner amancane naphakathi nendawo.

Enkathini yanamuhla yokukhula kwezimboni, ukulondolozwa kwemvelo sekuyinkinga ephuthumayo, okwenza "ukungathathi hlangothi kwekhabhoni" kube yinto eza kuqala. Ephendula lo mkhuba, umenzi we-S&A industrial chiller wenza umzamo ohlangene wokusebenzisa ama-refrigerant anobungani nemvelo. Ngokubambisana ekukhuthazeni ukusebenza kahle kwamandla nokunciphisa ukukhishwa kwegesi, singasebenza ekwakheni "idolobhana lomhlaba wonke" eliphawulwa yizindawo zemvelo ezihlanzekile.
