Cooling using the Peltier effect

This unit demonstrates thermoelectric cooling through the Peltier effect. By passing current through p- and n-doped semiconductor materials, one side becomes hot while the other becomes cold, creating a solid-state refrigeration effect.

• functional model of a Peltier refrigeration system
• water-cooled Peltier element for heat dissipation
• integrated water circuit with tank, pump, and rotameter flow meters
• electrical power adjustable via potentiometer
• digital displays for current, voltage, and temperature
