Not really : Peltier-based devices like this add (some) resistance to the heat flow. This added resistance means the air conditioner (or any heat pump, e.g. a fridge) gets less efficient. I think the energy captured by the device will always be lower than the extra energy needed for the heat pump. A device like this is not useful in a system where you are actively pumping heat around.
