A system and method for cooling structures by pulling air underground through corrugated pipe is disclosed. The system allows the air to cool down prior to being pulled back into the structure. The system comprises: a trench located outside the structure; an elongated pipe resting in the trench, having a first end and a second end; a first manifold connected to the first end of the elongated pipe, and a second manifold connected to the second end of the elongated pipe; a first airtight duct connecting the first manifold to the structure, and a second airtight duct connecting the second manifold to the structure; a duct fan coupled to the second set of ducting such that the duct fan causes air to flow through the first airtight duct to the first manifold, then to the elongated pipe, then through the second manifold, then through the second airtight duct back into the structure, thereby cooling the structure due to a naturally cooler temperature of the elongated pipe located in the trench. |

1. A system for cooling the interior of a structure comprising:
a. a trench located outside the structure; b. 2 or more elongated corrugated heat exchange pipes made of plastic, each of the elongated heat exchange pipes having a first end and a second end, wherein the elongated pipe rests in the trench, and wherein each of the corrugate elongated pipes are corrugated throughout their length; c. a first manifold connected to the first end of each elongated pipe, and a second manifold connected to the second end of each elongated pipe; d. a first duct with a first end connected to the first manifold and a second end connected to the structure; e. a second duct with a first end connected to the second manifold and a second end connected to the structure; f. a duct fan positioned such that the duct fan blows air out of the second duct creating a partial vacuum which pulls air as follows: from the structure through the first duct to the first manifold, then to the elongated pipes, then though the second manifold, then through the second duct back into the structure, thereby cooling the structure due to a naturally cooler temperature of the trench; g. wherein the first and second ducts are made of PCV pipe, wherein the first and the second manifold have a tapered design comprising:
i. a first rectangular portion having a first end and a second end wherein the second end is positioned opposite to the first endii. wherein the first end of the first rectangular portion connects each manifold to its respective duct;iii. wherein the second end of the first rectangular portion opens into a trapezoidal portion,iv. the trapezoidal portion has a shorter parallel side, a longer parallel side, and 2 non-parallel sides;v. the shorter parallel side connects to the first rectangular portion;vi. the longer parallel side connects to a second rectangular portion, the second rectangular portion having a first elongated side connected to the longer parallel side of the trapezoidal portion, and an opposite elongated side connected to the elongated corrugated pipes, and 2 shorter sides;vii. whereby this tapered design provides more equal air flow among the elongated pipes; h. a first plurality of lava rocks forming a first layer placed in the trench underneath the elongated pipe; i. a second plurality of lava rocks forming a second layer placed in the trench covering the elongated pipe; j. a layer of insulation covering the second layer of lava rocks throughout the length of the trench. |
