Ukuze uqonde ukuthi kungani isiqandisi se-R-22 singasasetshenziswa kuyunithi ye-industrial chiller, ake’ngizokwazi ukuthi yini isiqandisi kuqala. Isiqandisi siyinto esetshenziswa ohlelweni lwesiqandisi futhi ishintsha isigaba phakathi kwegesi noketshezi ukuze injongo yesiqandisi ifezeke. Kuyisici esibalulekile kumshini wokuwashisa amanzi wezimboni namanye amayunithi esiqandisi. Ngaphandle kwesiqandisi, isiqandisi sakho asikwazi ukupholisa kahle. Futhi i-R-22 bekuyifriji esetshenziswa kakhulu, kodwa manje isinqatshelwe ukusetshenziswa. Pho siyini isizathu?
I-R-22 refrigerant, eyaziwa nangokuthi i-HCFC-22, ingelinye lamalungu omndeni wakwaFreon. Bekukade kuyisibandisi esikhulu se-AC yasekhaya, i-central AC, i-industrial water chiller, imishini yesiqandisi sokudla, iyunithi yesiqandisi sokuhweba nokunye. Nokho, kamuva i-R-22 yatholakala iyingozi endaweni ezungezile, njengoba izoqeda ungqimba lwe-ozone olusivikela emisebeni yelanga e-ultraviolet futhi yenze umonakalo obamba ukushisa ube mubi kakhulu. Ngakho-ke, ngokushesha wavalwa ukuze kuvikelwe indawo ezungezile kangcono.
Kanjalo zikhona ezinye izindlela eziwinile’t ukucekela phansi ungqimba lwe-ozone futhi ibe nobungane emvelweni? Nokho, zikhona. I-R-134a, i-R-407c, i-R-507, i-R-404A kanye ne-R-410A ibhekwa njengefaneleka kakhulu esikhundleni sesiqandisi se-R-22. Asebenza kahle kakhulu futhi noma kukhona ukuvuza kwesiqandisi, abasebenzisi bawinile’kufanele ngicabangele ukuthi zizoholela ekufudumaleni komhlaba.
Njengomkhiqizi othembekile wezimboni zokuthomba, asisebenzisi lutho ngaphandle kweziqandisi ezilungele imvelo kumayunithi ethu okushisa embonini -- R-134a, R-407c kanye ne-R-410A. Amamodeli ahlukene afaka iziqandisi asebenzisa izinhlobo ezahlukene kanye nenani leziqandisi ukuze abe nekhono eliphelele lesiqandisi. I-chiller yethu ngayinye ihlolwa ngaphansi kwesimo esilingiswayo somthwalo futhi sivumelana nezinga le-CE, RoHS kanye ne-REACH. Uma ungenaso isiqiniseko sokuthi yiluphi uhlobo lwesiqandisi olusetshenziswa endaweni yakho yokupholisa, ungashiya umyalezo noma i-imeyili
