Peltier heating and cooling systems offer precise control as well as a big energy saving when compared to traditional compressor methods.
Heating and Cooling
The technology offers both heating and cooling – if a voltage is placed across a Peltier element one side is cooled and the opposite side simultaneously heats up. By reversing the polarity of the supply voltage the hot and cold sides swap.
Peltier technology works well at temperatures close to ambient or room temperature, as energy is only needed if heating or cooling is needed.
This gives large energy savings when compared to traditional compressor systems, as shown in the graph below.
