Abstract:

The present invention relates to a heating and cooling system for structures such as residential dwellings. More particularly, the heating and cooling system includes one or more conduits disposed approximately six (6) feet underground and having opposite end extremities communicatively connected to the structure so as to define a closed air circulation system through the structure and one or more conduits. A fan assembly including appropriate controls is provided to induce and circulate air through the structure and through the one or more conduits such that a system of air may be continuously circulated from the structure through the underground disposed conduits and back through the structure. When the temperature of ambient air is significantly greater than or less than the temperature of the earth or ground around the conduits, a temperature gradient is established and the earth around and in the vicinity of the conduits becomes a medium of heat exchange relative to air passing through the one or more conduits. Thus, depending on the ambient air temperature, the system of the present invention will either heat or cool the structure.
