Ulwahlulo kunye nentshayelelo ye-Industrial Water Chiller Refrigerant

Ngokusekwe kulwakhiwo lweekhemikhali, iifriji ze-industrial chiller zinokwahlulwa zibe ziindidi ezi-5: iifriji ze-inorganic compound, i-freon, i-saturated hydrocarbon refrigerants, iifriji ze-hydrocarbon ezingaxutywanga, kunye ne-azeotropic mix refrigerants. Ngokoxinzelelo lwe-condensing, iifriji ze-chiller zingahlelwa kwiindidi ezi-3: i-high-temperature (i-low-pressure) ifriji, i-medium-high (i-medium-pressure) ifriji, kunye ne-low-high (high-pressure) iifriji. Iifriji ezisetyenziswa kakhulu kwimizi-mveliso yokupholisa yi-ammonia, i-freon, kunye ne-hydrocarbons.

Kwinqanaba lokuqala lophuhliso lwemizi-mveliso, i-R12 ne-R22 yayisetyenziswa kuninzi lwezixhobo zokukhenkceza kwimizi-mveliso. Umthamo wokupholisa we-R12 mkhulu kakhulu, kwaye ukusebenza kwawo kwamandla kuphezulu. Kodwa i-R12 yabangela umonakalo omkhulu kucwecwe lweozone yaye yalelwa kumazwe amaninzi.

Izikhenkcezisi i-R-134a, i-R-410a, kunye ne-R-407c, ngokuthobela imfuneko yokhuselo lwemo engqongileyo yamazwe ngamazwe, zisetyenziswa S&I-industrial chillers :

(1)R-134a (Tetrafluoroethane) Isikhenkcisi

I-R-134a sisikhenkcisi esaziwayo kwihlabathi jikelele esiqhele ukusetyenziswa njengokutshintsha i-R12. Inobushushu bomphunga obuyi -26.5°C kwaye yabelana ngeempawu ezifanayo ze-thermodynamic kunye ne-R12. Nangona kunjalo, ngokungafaniyo ne-R12, i-R-134a ayinabungozi kwi-ozone layer. Ngenxa yoku, isetyenziswa kakhulu kwii-air conditioners zeenqwelo, kwiinkqubo zorhwebo kunye nefektri yefektri, kunye ne-arhente ekhupha amagwebu ukuvelisa izinto eziqinileyo zeplastiki. I-R-134a ingasetyenziselwa ukwenza ezinye izikhenkcisi ezixubeneyo, ezifana ne-R404A kunye ne-R407C. Eyona ndlela isetyenziswayo njengenye yefriji ukuya kwi-R12 kwizikhenkcezisi zomoya ezimotweni kunye nesikhenkcisi sefriji.

(2)R-410a Isikhenkcisi

IiPropati zeMzimba kunye neMichiza: Ngaphantsi kobushushu obuqhelekileyo kunye noxinzelelo, i-R-410a i-chlorine-free, i-fluoroalkane, i-refrigerant engekho i-azeotropic edibeneyo. Yigesi engenambala, exineneyo enyibilikisiweyo egcinwe kwiisilinda zentsimbi. Nge-Ozone Depletion Potential (ODP) ye-0, i-R-410a yifriji ehambelana nokusingqongileyo engonakalisi i-ozone layer.

ISicelo esiPhambili: I-R-410a isetyenziswa ikakhulu endaweni ye-R22 kunye ne-R502. Iyaziwa ngokucoceka kwayo, ubutyhefu obuphantsi, ukungatsha, kunye nokusebenza okugqwesileyo kokupholisa. Ngenxa yoko, isetyenziswa ngokubanzi kwii-air conditioners zasekhaya, ii-air conditioners ezincinci zorhwebo, kunye ne-air conditioners yendlu.

(3)R-407C Isikhenkcisi

Iimpawu zePhysical and Chemical: R-407C yi-chlorine-free fluoroalkane non-azeotropic exutywe efrijini phantsi kobushushu obuqhelekileyo kunye noxinzelelo. Yigesi engenambala, exineneyo enyibilikisiweyo egcinwe kwiisilinda zentsimbi. Ine-Ozone Depletion Potential (ODP) ye-0, iyenza kwakhona ifriji ehambelana nokusingqongileyo engonakalisi i-ozone layer.

ISicelo esiPhambili: Njengokutshintshwa kwe-R22, i-R-407C ibonakaliswe ngokucoceka kwayo, ubutyhefu obuphantsi, ukungatsha, kunye nokusebenza okugqwesileyo kokupholisa, okusetyenziswa ngokubanzi kwii-air conditioners zasekhaya kunye nezincinci kunye neziphakathi zomoya zomoya.

Kweli xesha lanamhlanje lokukhula kwemizi-mveliso, ukugcinwa kwendalo kube yinkxalabo engxamisekileyo, nto leyo eyenza "ukungathathi hlangothi kwekhabhoni" kube yeyona nto iphambili. Ukuphendula kulo mkhwa, S&Umvelisi we-industrial chiller yenza iinzame ezimanyeneyo zokusebenzisa iifriji ezilungele indalo. Ngokusebenzisana nokukhuthaza ukusebenza kakuhle kwamandla kunye nokunciphisa ukukhutshwa kwezinto ezikhutshwayo, sinokusebenzela ekudaleni "ilali yehlabathi" ephawulwe ngobume bendalo obucocekileyo.
