How to find tonnage or KW, EER of refrigerator
(OP)
Why do refrigerators doesnt quote the rating in tons . How to calculate the EER and Tons from the data available on the plate attached to refrigeraor.

Failing that, ask a senior person in your office.

From the information on your picture it is not possible to calculate the capacity.

For example, if COP is approx 2.5 for an air cooled condensor condensing at 100degF, evaporating at -30degF, then refrig capacity, peak would be 105 x 2.5 = 263W = 897Btu/hr = 0.075tons refrig capacity
While refrig capacity, normal, continous, assuming the compressor runs for say 30% of the time = 263 x 0.3 = 79W = 269Btu/hr = 0.022tons refrig capacity
COP would of course be better in winter and lower in hot weather. Net cooling capacity would also depend on insulation from ambient heat leak into the fridge.
1 ton of refrigeration capacity = 12000Btu/hr
COP = Net refrig effect (sat vap enthalpy - sat liquid enthalpy, Btu/lb)/ heat of compression, Btu/lb
