When to consider TEC?
TEC can be used in different application where cooling or temperature control of an object is
required.
In general, TEC is most often used when an object: 1. Needs to be cooled below the ambient temperature, or 2. Requires to be maintained at a consist temperature under a fluctuating ambient temperature. TEC is perfect for cooling a small, low heat load object.
Due to the low COP (Coefficient of Performance) compared with compressor cooling, TEC looses its advantage if the cooling load is higher than 200 watts. But, because TECs have no moving parts, they are lightweight and reliable, they create no electrical noise, and can be operated at any orientation or environment, in some instances TECs are used to cool kilowatts of heat.
TEC is exceptionally suitable for a precision temperature control of an object such as a laser
diode, CCD or other small objects. Paired with a DC power supply and an electronics
proportional/integral (PI) controller packaged in a single chip device, TEC is able to control an
object to +/- 0.1oC accuracy. Today, no other cooling method yet can provide such precise,
simple and convenient temperature control.
