So... they are dumping the heat where? outside? on a hot day? Efficient? Some kids need to look up the word and learn how to calculate it.

Where do you think a traditional AC unit dumps its heat? Surely you don't think it stores it away into a heat piggy-bank to be used when you turn the heater on in the winter...

The traditional system does not just move heat around. Do you know about the temperature effects of pressure change?

But yeah, the traditional system does dump heat. It just does not need as much of a heat difference in order to move that heat. My last post was missleading if not inacurate. Peltiers need help to get rid of heat. AC closed loop systems don't need much.
