cessation of all life (metabolic) processes. Death may involve the organism as a whole (somatic death) or may be confined to cells and tissues within the organism. Causes of death in human beings include injury, acute or chronic disease, and neoplasia (cancer).
R409A is a blend of HCFC refrigerants introduced to retrofit R12 in air conditioning and refrigeration applications.CFCâs are commonly accepted as having an overall detrimental effect on the environment through both their ozone depletion potential and global warming potential and consequently are being phased out completely.
R-12 (dicholordifluoromethane) is the refrigerant used in virtually every residential refrigerator, every auto air conditioner, and in most commercial coolers. The replacement of Refrigerant 12 will directly affect consumers the most. The first location will be in the automotive air conditioner. The new replacement for R-12 is R-134a which is not a Freon, but a Suva. R-134a is less efficient than R-12 and operates at a higher pressure.
