Ukulawulwa Kwezinga lokushisa Okunembile Kwezinhlelo Ze-Laser Nezicelo Zezimboni Kusukela ngo-2002
Ulimi
Ngokusekelwe ekwakhiweni kwamakhemikhali, iziqandisi ezibandayo zasezimbonini zingahlukaniswa ngezigaba ezi-5: iziqandisi ezihlanganisiwe ezingaphili, i-freon, iziqandisi ze-hydrocarbon ezigcwele, iziqandisi ze-hydrocarbon ezingagcwalisiwe, neziqandisi eziyingxube ze-azeotropic. Ngokuvumelana nengcindezi yokujiya, iziqandisi ezibandayo zingahlukaniswa zibe izigaba ezi-3: iziqandisi ezishisa kakhulu (umfutho ophansi), iziqandisi ezisezingeni lokushisa elimaphakathi (ingcindezi emaphakathi), neziqandisi ezinokushisa okuphansi (umfutho ophezulu). Iziqandisi ezisetshenziswa kakhulu kumakhaza ezimboni yi-ammonia, i-freon, nama-hydrocarbon.
Ekuqaleni kokuthuthukiswa kwezimboni, u-R12 no-R22 wasetshenziswa emishinini eminingi yesiqandisi yezimboni. Umthamo wokupholisa we-R12 mkhulu kakhulu, futhi amandla ayo okusebenza kahle nawo aphezulu. Kodwa u-R12 wabangela umonakalo omkhulu ongqimbeni lwe-ozone futhi wenqatshelwe emazweni amaningi.
Iziqandisi i-R-134a, i-R-410a, ne-R-407c, ngokuhambisana nemfuneko yokuvikelwa kwemvelo yamazwe ngamazwe, zisetshenziswa S&A ama-chillers wezimboni:
(1)R-134a (Tetrafluoroethane) Isiqandisi
I-R-134a isiqandisi esaziwayo emhlabeni wonke esivame ukusetshenziswa esikhundleni sika-R12. Inezinga lokushisa elihwamukayo elingu -26.5°C futhi ihlanganyela ngezakhiwo ze-thermodynamic ezifanayo no-R12. Nokho, ngokungafani ne-R12, i-R-134a ayinabungozi ongqimbeni lwe-ozone. Ngenxa yalokhu, isetshenziswa kakhulu kuma-air conditioner ezimoto, ezinhlelweni zesiqandisi zezentengiselwano nezimboni, futhi njenge-ejenti enegwebu yokukhiqiza izinto eziqinile zokufakwa kwepulasitiki. I-R-134a ingasetshenziswa futhi ukwakha ezinye iziqandisi ezixubile, njenge-R404A ne-R407C. Isetshenziswa kakhulu njengesiqandisi ku-R12 kuma-air conditioner ezimoto kanye nesiqandisi esiqandisini.
(2)R-410a Isiqandisi
Izakhiwo Zomzimba Nezamakhemikhali: Ngaphansi kwezinga lokushisa elivamile nokucindezela, i-R-410a iyi-chlorine-free, i-fluoroalkane, isiqandisi esixubile esingeyona i-azeotropic. Kuyigesi engenambala, ecindezelwe ewuketshezi egcinwa kumasilinda ensimbi. Nge-Ozone Depletion Potential (ODP) engu-0, i-R-410a iyisiqandisi esivumelana nemvelo esingalimazi ungqimba lwe-ozone.
Isicelo Esiyinhloko: I-R-410a isetshenziswa kakhulu esikhundleni sika-R22 no-R502. Yaziwa ngokuhlanzeka kwayo, ubuthi obuphansi, ukungashi, nokusebenza okuhle kakhulu kokupholisa. Ngenxa yalokho, isetshenziswa kabanzi kuma-air conditioner asendlini, ama-air conditioner amancane ezentengiselwano, kanye nama-air conditioner asendlini.
(3)R-407C Isiqandisi
Izakhiwo Zomzimba Nezamakhemikhali: I-R-407C iyisiqandisi esixubile se-fluoroalkane esingenayo i-azeotropic ngaphansi kwezinga lokushisa elivamile nokucindezela. Kuyigesi engenambala, ecindezelwe ewuketshezi egcinwa kumasilinda ensimbi. Ine-Ozone Depletion Potential (ODP) engu-0, okuyenza ibe nesiqandisi esivumelana nemvelo esingalimazi ungqimba lwe-ozone.
Isicelo Esiyinhloko: Njengokushintshwa kwe-R22, i-R-407C ibonakala ngokuhlanzeka kwayo, ubuthi obuphansi, ukungashi, kanye nokusebenza okuhle kakhulu kokupholisa, okusetshenziswe kabanzi kuma-air conditioner asendlini kanye nama-air conditioner amancane naphakathi nendawo.
Esikhathini sanamuhla sokukhula kwezimboni, ukulondolozwa kwemvelo sekuyinto ekhathazayo, okwenza "ukungathathi hlangothi kwekhabhoni" kube yinto ehamba phambili. Ukusabela kulo mkhuba, S&A umkhiqizi we-industrial chiller yenza umzamo ohlangene wokusebenzisa iziqandisi ezinobungani nemvelo. Ngokuphromotha ngokuhlanganyela ukusebenza kahle kwamandla nokunciphisa ukukhishwa kwekhabhoni, singasebenzela ukwakha "isigodi somhlaba wonke" esibonakala ngezindawo zemvelo ezihlanzekile.
Sikhona ngenxa yakho uma usidinga.
Sicela ugcwalise ifomu ukuze uxhumane nathi, futhi sizokujabulela ukukusiza.

I-TEYU S&A Chiller yasungulwa ngo-2002 ineminyaka engama-23 yesipiliyoni sokukhiqiza okupholile, futhi manje isiqashelwa njengephayona lobuchwepheshe bokupholisa kanye nozakwethu onokwethenjelwa embonini ye-laser.
