It's a measure of how much more cooling you get than power you get in (yes,
I know it sounds weird). An EER of 10 says that for each watt of power put
into the compressor, 11 watts of heat dissipation go out the radiator. Ten
watts of energy (heat) get sucked out of the room. It's related to Carnot
engines, which are really a mechanical engineering question, so I won't
explain further. E-mail me if you really care.
