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.
Background. 1  R32 is a synthetic HFC refrigerant designed for use in HVAC systems. 2  R32 has a GWP of 650* compared to R410A, which has a GWP of 1725*. 3  R32 is seen as a suitable alternative to R410A and R22 in air conditioning systems designed for R32. 4  Air conditioning manufacturers have commenced supplying R32 charged residential air conditioning ... R32 is not a new refrigerant. 2  R32 is a major component of other refrigerants, making up 50% of the R410A blend and 23% of the R407C blend. 3  R32 in its pure form is classified as A2 (â¥ 3.5% LEL) according to AS/NZS 1677.1:1998.
