The EER of an air conditioner is its British Thermal Units (BTU) rating over its wattage. For instance, if a 10,000BTU 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
