Uhlu kunye neNtshayelelo yeRefrigerant ye-Industrial Water Chiller

Ngokusekelwe kwiikhemikhali, iifriji ze-industrial chiller zingahlulwahlulwa zibe ziindidi ezi-5: iifriji ze-inorganic compound, i-freon, iifriji ze-hydrocarbon ezigcweleyo, iifriji ze-hydrocarbon ezingagcwaliyo, kunye neefriji ze-azeotropic mixed. Ngokwengcinezelo yokuxinana, iifriji ze-chiller zingahlulwahlulwa zibe ziindidi ezi-3: iifriji ze-high-temperature (low-pressure), iifriji ze-medium-temperature (medium-pressure), kunye neefriji ze-low-temperature (high-pressure). Iifriji ezisetyenziswa kakhulu kwii-industrial chillers yi-ammonia, i-freon, kunye nee-hydrocarbons.

Kwinqanaba lokuqala lophuhliso lwemizi-mveliso, i-R12 kunye ne-R22 zazisetyenziswa kwizixhobo ezininzi zokukhenkceza kwimizi-mveliso. Amandla okupholisa e-R12 makhulu kakhulu, kwaye ukusebenza kakuhle kwamandla nawo kuphezulu. Kodwa i-R12 yabangela umonakalo omkhulu kumaleko we-ozone kwaye yayingavumelekanga kumazwe amaninzi.

Iifriji R-134a, R-410a, kunye ne-R-407c, ngokuhambelana nemfuneko yokukhuselwa kwendalo yamazwe ngamazwe, zisetyenziswa kwiifriji ze-S&A zoshishino :

(1)R-134a (Tetrafluoroethane) Isiqandisi

I-R-134a yifriji eyaziwayo kwihlabathi liphela esetyenziswa rhoqo endaweni ye-R12. Inobushushu bokufuma obuyi--26.5°C kwaye ineempawu ezifanayo ze-thermodynamic ne-R12. Nangona kunjalo, ngokungafaniyo ne-R12, i-R-134a ayinabungozi kumaleko we-ozone. Ngenxa yoku, isetyenziswa kakhulu kwii-air conditioner zezithuthi, kwiinkqubo zokukhenkceza zorhwebo nezemizi-mveliso, kwaye njengearhente yokufutha igwebu ekwenzeni izinto zokukhusela zeplastiki eqinileyo. I-R-134a ingasetyenziselwa ukwenza ezinye ii-refrigerants ezixutyiweyo, ezifana ne-R404A kunye ne-R407C. Ukusetyenziswa kwayo okuphambili kukusetyenziswa njengefriji eyahlukileyo kune-R12 kwii-air conditioner zezithuthi kunye nefriji yefriji.

(2)R-410a Isiqandisi

Iimpawu Zomzimba Neekhemikhali: Phantsi kobushushu obuqhelekileyo kunye noxinzelelo, i-R-410a yifriji exutyiweyo engenachlorine, i-fluoroalkane, ne-non-azeotropic. Yigesi engenambala, ecinezelweyo egcinwe kwiisilinda zentsimbi. Nge-Ozone Depletion Potential (ODP) ye-0, i-R-410a yifriji enobuhlobo nokusingqongileyo engonakalisi umaleko we-ozone.

Eyona Ndlela Isetyenziswa Ngayo: I-R-410a isetyenziswa kakhulu endaweni ye-R22 kunye ne-R502. Yaziwa ngokucoceka kwayo, ukuba netyhefu encinci, ukungatshi, kunye nokusebenza kakuhle kokupholisa. Ngenxa yoko, isetyenziswa kakhulu kwii-air conditioner zasekhaya, ii-air conditioner ezincinci zorhwebo, kunye nee-air conditioner eziphakathi zasekhaya.

(3)R-407C Isiqandisi

Iipropati Zomzimba Neekhemikhali: I-R-407C yi-fluoroalkane non-azeotropic mixed refrigerant engenachlorine phantsi kobushushu obuqhelekileyo kunye noxinzelelo. Yigesi engenambala, ecinezelweyo egcinwe kwiisilinda zentsimbi. Ine-Ozone Depletion Potential (ODP) ye-0, nto leyo eyenza ukuba ikwayi-refrigerant enobuhlobo nokusingqongileyo engonakalisi umaleko we-ozone.

Eyona Ndlela Isetyenziswa Ngayo: Njengendawo ye-R22, i-R-407C ibonakaliswa kukucoceka kwayo, ukuba netyhefu ephantsi, ukungatshi, kunye nokusebenza kwayo kakuhle kokupholisa, isetyenziswa kakhulu kwii-air conditioner zasekhaya kunye nee-air conditioner ezincinci neziphakathi eziphakathi.

Kule mihla yokukhula kwemizi-mveliso, ukugcinwa kokusingqongileyo kuye kwaba yinto exhalabisayo, nto leyo eyenza ukuba "ukungathathi cala kwekhabhoni" kube yeyona nto iphambili. Ukuphendula le meko, umenzi we-S&A industrial chiller wenza umzamo odibeneyo wokusebenzisa iifriji ezinobuhlobo nokusingqongileyo. Ngokukhuthaza ngokubambisana ukusetyenziswa kwamandla kunye nokunciphisa ukukhutshwa komoya, singasebenza ekudaleni "ilali yehlabathi" ephawulwa ziimbonakalo zendalo ezicocekileyo.
