Thermofusion: Dual Heating and Cooling System Using Peltier Module

This paper presents the design and development of a two-in-one refrigerator and heating system utilizing Peltier modules, which are semiconductor devices capable of both heating and cooling through the Peltier effect. In this system, the refrigerator and heating share a common Peltier module setup, with one side of the module providing cooling for refrigeration, while the opposite side generates heat for the heating. A controlled mechanism is introduced to isolate the two compartments and maintain appropriate temperatures for each function. Temperature regulation is achieved through sensors and microcontroller-based control circuits, which dynamically adjust the electric current to optimize performance for both heating and cooling processes. COP Cooling capacity and Cooling power is analyzed for different input parameters Keywords: Thermoelectric effect, Peltier Effect, Solid-state Cooling, Refrigeration, Heating, Coefficient of performance.
