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.
A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle.his will ban potent greenhouse gases such as the refrigerant HFC-134a (also known as R-134a in North America) âwhich has a GWP of 1410âto promote safe and energy-efficient refrigerants. One of the most promising alternatives is CO 2 (R-744).
