Hello, my question is simple but the answer may be a little less.
I would like to know the COP of a peltier module used for heating and not for cooling.
I tried to find on the net but everyone apparently only uses the cooling function.
I wondered if we transposed it on the principle of a heat pump, ie like a geothermal for example that it would be are COP.
please
Heat pump with peltier module
Hello aidiv
I have a small Peltier effect module. I also use it to cool or rather to dissipate the heat of a processor. It creates a DT ° of 67 ° at 15,4VDC at 6A. For my part it measures 40x40mm. The electrical consumption seems important to me for such a small component. At its maximum power it is 55W.
An electrical resistance would make P = UxI 15,4x6 = 92,4W.
In the case of my component, the values are given for a DT ° between the two walls. Whether it works hot or cold there is no difference. So I think it is not interesting because it absorbs 92,4W and provides 55W COP of 0,6 resistance to a COP of 1 a PAC to a COP of 2,5 to 3. In my opinion if components of this size were as greedy as heat pumps there will be more fans in the computers, ect ...

Hello,
The peletiers indeed have a low yield and are not suitable for large volumes, they are interesting for "making cold on a small surface" without having to install a whole system of gas exchanger, which would certainly have a much better yield.
It is more a question of mechanical ease than attention to real efficiency.

This is not because we always said that it is impossible that we should not try
