How Thermoelectric Air Conditioners Operate and Their Benefits
A thermoelectric air conditioner cools spaces using special technology. It works with the Peltier effect, which moves heat. When electricity flows through a module, heat shifts from one side to the other. One side gets cold, and the other side gives off heat. Unlike regular systems, it has no moving parts or refrigerants. This makes it very efficient.
Thermoelectric air conditioners are great for cooling small or medium spaces. For instance, the TEC-12706 module cools well and costs less to install and maintain than regular systems.

How Thermoelectric Cooling Works
The Peltier effect and its role in cooling
The Peltier effect is key to thermoelectric cooling. When electricity passes through a module, heat moves between sides. One side gets cold, while the other side releases heat. It works like a heat pump but has no moving parts or liquids.
The process depends on materials and electric current. For example, at 0.3 A mm−2, the temperature changes less than 0.1 K in 10 milliseconds. At 1.5 A mm−2, the change ranges from 0.08 K to 0.34 K. After 0.17 seconds, the temperature difference reaches 4.6 K. These quick changes show how well the Peltier effect cools.
Performance Metric | Value | Description |
|---|---|---|
Coefficient of Performance (COP) | 0.92 | Shows how efficient the air conditioner is under certain conditions. |
Cooling Capacity | 157.0 W | Heat removed from the system at a specific voltage. |
Outlet Air Temperature | 28 °C | Air temperature after passing through the cooling system. |
The Peltier effect helps thermoelectric air conditioners cool spaces fast. It also avoids harmful refrigerants, making it better for the environment.
Heat transfer process in thermoelectric modules
Heat transfer in these modules happens in steps. First, the module absorbs heat from the area being cooled. This heat moves through conduction, convection, and radiation. The Peltier effect then shifts heat from the cold side to the hot side. Heat sinks and fans release the heat into the air.
Thermoelectric modules are carefully designed for heat transfer. They use the Peltier, Seebeck, and Thomson effects for better cooling. Materials like bismuth telluride and lead telluride improve these effects.
