I seem to get about 2.0 to 1.8 amps at the compressor during run cycle, on most of the 15 to 20 cu' boxes I have check lately, hardly ever below 1.6 amps.
refrigeration compressors are more efficient:
consider an air conditioner EER ratio
How is EER calculated?
The EER of an air conditioner is its British Thermal Units (BTU) rating over its wattage. For instance, if a 10,000-BTU air conditioner consumes 900 watts, its EER is 11 (10,000 BTU/900 watts). A higher EER means that the air conditioner is more efficient.
in your sample above:
if your fridge draws 1.6a @ 120v = 192w
900btu/192w = EER 4.7
1 kilowatt hour of electricity = 3413 British thermal units (Btus) = EER 3.143
