Simplified Peltier heat pump

Abstract

Abstract A simplified version of the Peltier heat pump has been described and its prototype subjected to experimental testing. The core of the prototype consists of the thermoelectric module TEC1-12714S which is commonly available on the electro market. The simplified Peltier heat pump has shown effective functioning within the temperature difference of ΔT = 20  °C between the cold and hot sides of the used module. Although the presented prototype of the Peltier heat pump does not seem to be practical in thermal building technology, its utilization for illustrating the principle of thermoelectric effect within physical lectures or as an experimental device for measuring its coefficient of performance in student laboratories may be useful.
