A method of installing an indoor cooling system, the method comprising:
- acquiring a collection of materials to build an indoor cooling system, wherein the collection of materials includes aluminum beverage cans, flexible hoses having opposed open ends, a fan, a first container, a second container, dehumidifying material, and a filter;
- forming a hole in the ground beneath an indoor region to be cooled, the hole having a depth of at least four meters;
- cutting tops and bottoms away from the aluminum beverage cans;
- duct taping the aluminum beverage cans together in series to form first and second elongated airflow passages having opposed open ends, wherein air forced into one open end flows through an airflow passage and exits at the opposed open end;
- duct taping a first flexible hose to a first open end of the first elongated airflow passage and to a first open end of the second elongated airflow passage, wherein air forced into the second open end of the first elongated airflow passage flows through the first elongated airflow passage, the first flexible hose, and the second elongated airflow passage, and exits at the second open end of the second elongated airflow passage;
- adjusting the first flexible hose so that the first elongated airflow passage is about parallel to the second elongated airflow passage and the first flexible hose forms a U-shape between the first and second elongated airflow passages to create an overall U-shaped airflow passage with both second open ends forming an inlet and an outlet to the overall U-shaped airflow passage that are arranged in about the same directional orientation;
- inserting the overall U-shaped airflow passage into the hole so that the inlet and outlet are elevated out of the hole and into the indoor region;
- filling the hole with ground material after inserting the overall U-shaped airflow passage into the hole;
- coupling a first end of a second flexible hose to the outlet of the overall U-shaped airflow passage;
- placing the second flexible hose and the inlet and outlet of the overall U-shaped airflow passage into the first container, the first container having openings at the bottom for the inlet and outlet, at the top for the fan, and at the side for the second flexible hose;
- placing the fan atop the first container so that air from the fan is directed through the top opening and into the inlet;
- coupling the second end of the second flexible hose to a first opening of the second container, the second container having an internal height and an internal width;
- shaping the dehumidifying material into a first panel and a second panel, wherein both the first panel and second panel have a height and a width that matches the internal height and the internal width of the second container;
- coupling the first panel and the second panel to internal walls of the second container to form three separate compartments within the second container, wherein air entering at the first opening of the second container enters a first compartment, is forced through the first panel into a second compartment, and is forced through the second panel into a third compartment before exiting at the second opening of the second container;
- installing the filter at the second opening of the second container;
- and
- operating the fan to force air at a first temperature into the indoor cooling system through the inlet of the overall U-shaped airflow passage, wherein the air is cooled geothermally as it travels through the overall U-shaped airflow passage, exits the outlet of the overall U-shaped airflow passage at a second temperature that is lower than the first temperature, and is dehumidified by the dehumidifying material before exiting the indoor cooling system at the filter.
