Thermal Electric Cooling(TEC)

Equipment demand for climate controlled enclosures increase as reliability and steady performance remain top priorities. Adaptability is key when choosing Thermoelectric Cooling (TEC) units. Being DC powered, they are suitable for both primary and backup cooling/heating duties.TEC’s pack a mighty punch in a low profiled compact design that can mount in the smallest of areas, unlike compressor based units, TEC’s can be mounted vertically or horizontally as the application requires. Add to this the reliability of the Peltier system that has no moving parts (the fans on the inside and outside are the only moving parts) and with a filter less design, it is easy to see why TEC’s are so popular.

• DC Powered operation for 24V or 48V applications
• Low profile design allows for mounting vertically and horizontally
  on any enclosure to avoid interference with internal components
• Filterless design reduces maintenance requirements
• Contains no refrigerant, making it earth friendly
• Prewired with simple terminal block for easy wiring connections
• Operates on the Peltier effect for cooling or heating
• 100W,200W or 300W TEC
• Compressor-free air conditioning for demanding indoor and outdoor applications

A thermoelectric cooler (TEC), sometimes called a thermoelectric module or Peltier cooler, is a semiconductor-based electronic component that functions as a small heat pump. By applying a low voltage DC power source to a TE module, heat will be moved through the module from one side to the other. One module face, therefore, will be cooled while the opposite face simultaneously is heated. It is important to note that this phenomenon may be reversed whereby a change in the polarity (plus and minus) of the applied DC voltage will cause heat to be moved in the opposite direction. Consequently, a thermoelectric module may be used for both heating and cooling thereby making it highly suitable for precise temperature control applications.

• What are the applications of thermoelectric cooling?

The thermoelectric cooling applications have been reviewed in aspects of domestic refrigeration, electronic cooling, scientific application, and automobile air conditioning and seat temperature control, with summaries for the commercially available thermoelectric modules and thermoelectric refrigerators.

• Can a thermoelectric cool and heat at the same time?

Ability to Heat and Cool With the Same module: Thermoelectric coolers will either heat or cool depending upon the polarity of the applied DC power. This feature eliminates the necessity of providing separate heating and cooling functions within a given system.

• What is better thermoelectric or compressor?

Because they have less moving parts and require much less power to operate, thermoelectric cooled wine refrigerators use much less energy than compressor cooled units. This feature not only benefits the customer, but the environment as well

• Why Peltier is not used in AC?

Most thermoelectric coolers won't cool below about 50°F. In addition, thermoelectric coolers aren't recommended for use in spaces that get warmer than 80°. This is because the Peltier device is not capable of great heat flux, and can really only lower the temperature about 20 degrees.

• How Do Thermoelectric Coolers (TECs) Work?

Thermoelectric coolers operate according to the Peltier effect. The effect creates a temperature difference by transferring heat between two electrical junctions. A voltage is applied across joined conductors to create an electric current. When the current flows through the junctions of the two conductors, heat is removed at one junction and cooling occurs. Heat is deposited at the other junction.

The main application of the Peltier effect is cooling. However the Peltier effect can also be used for heating or control of temperature. In every case, a DC voltage is required.
