ABSTRACT:
An underground air cooling system and method for at least one building including an air line disposed beneath the ground for conveying air to an I-tank filled with fluid that is also disposed beneath the ground. The fluid in the lower compartment of the I-tank absorbs heat from the air in the air line and dissipates that heat quickly to the surrounding earth and to the fluid in the upper compartment of the I-tank. In addition, a fluid line is connected to the I-tank and is interposed in the path of the air in the air line. Cold water from the I-tank runs through the water line. As air passes over the fluid line in the air line, the air is further cooled and dehumidified before being conveyed to a building to be cooled. In a preferred embodiment, a second water line is connected to the lower compartment of the I-tank and is disposed in different parts of a building so that cool water from the I-tank runs through coils of the second water line in different portions of the building. A fan can be provided to blow air over the coils of the second fluid line thereby further cooling the air in the building.
