ABSTRACT:
An underground air tempering system for warming the supply air to a building in the winter and cooling the supply air in the summer in which a heat exchanger containing heat transfer material is disposed beneath the surface of the ground and the air supply to the building is drawn through the heat exchanger to be tempered by the substantially constant ground temperature. Two or more heat exchangers may be interconnected on the air supply and air distribution ends for supplying a sufficient volume of tempered air to large buildings. The underground air tempering system cleanses the air by removing dust and other particles therefrom, and moderates the humidity of the air by warming and humidifying cold dry winter air and by cooling and dehumidifying hot moist summer air. To maintain free flowing air passages, and to eliminate fungal and bacterial growth in the heat exchanger, a disinfectant and wash solution system is disposed above the heat transfer material for periodic cleansing of the material.
