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-409A; A1 Safety Classification. Replaces. R-12. Applications. Medium-and low-temperature positive displacement equipment in supermarket systems and walk-in coolers. Benefits. 1  Works with existing mineral oil (MO) in many unitary and close-coupled systems.2  Alkylbenzene (AB) oil is recommended for optimum oil return.uvaâ¢ 409A refrigerant. Suvaâ¢ 409A, an HCFC-based refrigerant, is a cost-effective retrofit refrigerant for R-12 stationary positive displacement air-conditioning and refrigeration systems such as walk-in coolers, beverage dispensers, vending machines, and supermarket systems.
