Cool Air Loop Method

Abstract

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.

What is claimed is: 
     
         1 . A method of installing a system for cooling the interior of a structure comprising the steps of:
 a. digging a trench outside of the structure with a minimum length of 30 feet, a minimum width of 2 feet, and a minimum depth of 5 feet;   b. installing a first plurality of lava rocks into the trench such that the lava rocks form a first 3 inch deep layer;   c. providing:
 i. an elongated corrugated heat exchange pipe made of flexible thin plastic having a first end and a second end; 
 ii. a first tapered manifold and a second tapered manifold; 
 iii. a first smooth duct and a second smooth duct, both ducts being made of smooth wall, thick insulated plastic; 
 iv. 2 inch rigid rodent-resistant insulation; 
 v. a thermostat; 
 vi. at least one solar panel; 
 vii. a duct fan; 
   d. connecting the first tapered manifold to the first end of the corrugated elongated pipe;   e. connecting the second tapered manifold to the second end of the corrugated elongated pipe thereby forming an assembly;   f. placing assembly into the trench;   g. connecting a first end of the first duct to the first manifold;   h. connecting a second end of the second duct to the second manifold;   i. filling the trench with a second plurality of lava rocks forming a second 3 inch layer on top of the elongated corrugated pipe;   j. installing the 2 inch rigid rodent-resistant insulation into the trench such that it completely covers the elongated corrugated pipe;   k. connecting a second end of the first duct to the structure;   l. connecting a second end of the second duct to the structure;   m. configuring the duct fan such that it blows air out of the second duct creating a partial vacuum which pulls air through the system as follows:
 i. from the structure to the first duct; 
 ii. from the first duct into the first tapered manifold; 
 iii. from the first tapered manifold into the elongated corrugated pipe; 
 iv. from the elongated corrugated pipe into the second tapered manifold; 
 v. from the second tapered manifold into the second duct; 
 vi. from the second duct back into the structure, thereby cooling the structure due to a naturally cooler temperature of the elongated pipe located in the trench; 
   n. configuring the solar panel to power the duct fan and the thermostat;   o. configuring the thermostat to regulate the operation of the duct fan;   p. backfilling the trench with dirt.
