How does an air-to-air exchanger work?
Air-to-air exchangers utilize the Peltier effect whereby the heat is transferred via the flow of current through thermoelectric modules. One part absorbs the heat and, as a consequence, reduces the temperature (cold side) and the other part dissipates the heat to ambient (hot side). Fans are used to move air over heat sinks attached to both the hot and cold sides of the thermoelectric modules.
