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.
Copelandâs lubricant recommendation for use with R-401B/409A is a mixture of 50% mineral oil and 50% alkylbenzene. Copeland approved polyol ester lubricants can also be used with R-401B/409A if the system is expected to be changed in the near future to an HFC refrigerant such as R-134a.f the actual refrigerant temperature measured is 6Â°F, the superheat is 6.2Â°F. To measure sub-cooling at the condenser outlet or at the TEV inlet to verify that a solid column of liquid is present, measure the pressure and the refrigerant temperature at the location that the sub-cooling information is needed.
