Abstract – ETHE based systems are increasingly being used to condition the air in commercial livestock buildings, greenhouses. Being result of a natural phenomenon deep ground as source and sink is available easily in most places in the world. Such a use is sustainable and equivalent to having a renewable energy source. ETHE based systems cause no toxic emission and therefore, are not detrimental to environment. It is this feature that motivated my work on Underground Erath Air Tunnel development. ETHEs have long life and require only low maintenance. However, initial installation costs are likely to be higher than the comparable conventional systems (Refrigerant Based). Ground source heat pumps (GSHP) are used in North America, Europe to heat and cool houses, complexes and offices. Over 550,000 units are reported to be in operation worldwide and some 66,000 are added annually (Geoscience Ltd, United Kingdom). But in India its wide opportunities are yet to be realised or tested, though experiments conducted based on the same at Gujarat and Madhurai stands as exceptions. IRTC (Integrated Rural Technical Centre), Mundur, Palakkad is a research centre of Kerala Shasthra Sahithya Academy and they have shown their interest in implementing this idea of Under Ground Earth Air Tunnel at their region. The Project aims at the designing, fabrication and result evaluation of Underground Earth Air Tunnel at IRTC considering the climatic and soil properties prevailing at the region of interest in an economical feasible manner. The fabrication, installation and experimentation analysis of Earth Air Tunnel was successfully completed there.
