Amazwe aseYurophu anezidingo eziqinile mayelana nama-friji apholile emoyeni. Enye yezimfuneko ukusebenzisa i-friji enobungani nemvelo. I-R407C ingeye-friji enobungani nemvelo. Ikhokhiswa i-refrigerant enobungani nemvelo ye-R407C futhi ngemvume ye-CE, ROHS, REACHE, ama-friji apholile emoyeni e-S&A Teyu angathunyelwa emazweni aseYurophu.
Ngokuphathelene nokukhiqiza, i-S&A Teyu itshale imishini yokukhiqiza engaphezu kwesigidi sama-yuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-industrial chiller kuya ekushiseni insimbi; ngokuphathelene nokuthutha, i-S&A Teyu isungule izindawo zokugcina impahla emadolobheni amakhulu aseShayina, njengoba inciphise kakhulu umonakalo obangelwa ukuthutha impahla ibanga elide, futhi ithuthukise ukusebenza kahle kwezokuthutha; ngokuphathelene nensizakalo yangemva kokuthengisa, isikhathi sewaranti siyiminyaka emibili.
