Earth air tunnel
WebEarth air tunnel or earth air heat exchanger is a pre-cooling or pre-heating system which consists of a pipe or network of pipes buried at a particular depth below the ground surface. It either cools the air by rejecting heat to the ground or heats the air absorbing heat from the ground. This technique utilises temperature difference between ...
