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.
1 Note: Puron refrigerant operates at 50 to 70 percent higher pressures than the R-22 used in older systems. 2  That alone is a reason that you wouldn't just dump new Puron refrigerant into an older R-22-designed HVAC system.efrigerant gases, metering devices & piping: This article series describes the properties of common and historic air conditioning refrigerants. We combine U.S. EPA information with supplemental data and descriptions of refrigerants, refrigerant replacement options for R12 and R22, and their basic data.
