Hydrogen, fluorine, carbon and chlorine are the main ingredients that is present in HCFC refrigerants.In the refrigerants like, R-123 and r-22, the potential of ozone depletion is more than 0. The presence of chlorine is more in chlorofluorocarbon(CFC). R12 is a CFC refrigerant. The refrigerants that do not contain any chlorine are R-134a, R-410A. refrigerants have an ozone depletion potential of more than zero .
