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.
By a moderator at Refrigeration Engineer: 1  16 EER means 16 Btu/hr of cooling for every watt of power used. 2  1 watt = 3.412 Btu/hr, so. 3  16 EER unit provides 16  3.412 = 4.69 watts of cooling for every watt of power used. This is the coefficient of performance (COP). 4  1 ton refrigeration = 4.712 horsepower, electric.
