I am wondering how to use peltier module (EVL31-050) as a heater?
I have a Al block that I want to heat it up by putting the cod side of the peltier module on it. the other side is in floating in air(ambient). I am wondering which side is working as a reference for temperature. If I connect the peltier module to a power supply , by increasing the voltage, how the temperature varies in both sides? if I have temperature increase in one side and the floating side keeps the same temp as ambient temperature or both have increase and decrease in temperature?
Thanks for ur help
