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.
Mainstream has reviewed many of the R-410A certification programs as well as the hype that goes along with much of the R-410A frenzy. R-410A is a high pressure refrigerant and therefore there are safety issues that technicians need to be aware of. R-410A is also a near azeotropic refrigerant, therefore charging and servicing these systems is different than other 400-series blended refrigerants.
