The compressor isn't located on the cooling chamber - it's on the other side of the insulation so the heat can be dumped to the room.
The self heating (for better or for worse) of a peltier is generated at the cooling chamber edge.
- fuzzfactor 4y agoThe compressor motor converts a large portion of the electricity it consumes directly into waste heat which is why the motor warms up much more than from the friction. This is in excess of the heat being removed from the refrigerated area. Air conditioners have the warm-running compressor outdoors, but refrigerated indoor appliances release that heat into the room along with the heat transferred from inside the refrigerator. And then the AC encounters further inefficiency as it next removes this heat from the room. Even the motor of a ceiling fan warms up a room (gradually) if there is no AC and windows/doors are not open adequately to let that heat escape. Ceiling fans have big motors and are best outdoors like at a tiki bar.
