11. What does a thermoelectric system offer over a compressor?
Thermoelectric coolers are solid-state heat pumps, which have no moving parts and do not require the use of harmful CFCs. Therefore, they are inherently reliable and require little or no maintenance. They are ideal for cooling applications that may be sensitive to mechanical vibration.
Their compact size makes them well suited for applications with space or weight limitations, such as portable or airborne equipment. The ability to use thermoelectric modules to heat or cool suits applications requiring temperature stabilization of a device over a wide ambient temperature range such as laser diodes.
