An air cooling device works by first cooling a volume of liquid down to a temperature that can be below freezing. That volume of liquid can remain cold for a long period o f time, requiring very little work on the part of the compressor, much like a kitchen refrigerator. Even when in use for cooling, besides the fan which is on all the time during use, the compressor is only required for short periods of time to maintain the cold temperaure of the liquid.
