Abstract

A system designed to introduce fresh air ventilation into the living space, eliminate contaminants, and add fresh air to augment a building's HVAC system. This is done in order to save energy, and the costs associated with heat loss or gain in a building. The system employs the use of geothermal energy conferred to air via a cavity which is constructed in the basement, on the slab, foundation, in the crawl space and/or attic of a building. This cavity is created to circulate, absorb and store/release the geo-solar characteristics of a building, taking advantage the consistent subterranean temperature of the earth and/or sun, in order to warm air from outside during the winter minimizing the foundation heat sink, and cool air during the summer. One or more heat exchangers are used to transfer the energy from contaminated air in the cavity to clean air destined for the HVAC system.

Claims10

Dependent claims

A method for regulating comfort of a building through geothermal energy conservation comprising:

an air system intaking fresh hot/humid air via an intake;
the air system routing the fresh hot/humid air to a heat exchanger;
the heat exchanger cooling the fresh hot/humid air, converting the fresh hot/humid air to cool fresh/humid air;
routing the cool fresh/humid air underground into a geo-loop exchange;
routing the cool fresh/humid air into a top portion of an evaporator-condensator-dehumidifier;
the evaporator-condensator-dehumidifier converting the cool fresh/humid air to cooler dryer air;
the air system routing the cooler dryer air to the building;
the air system collecting cool stale/dry air from the building;
the air system routing the cool stale/dry air to the heat exchanger;
the heat exchanger converting the cool stale/dry air to hot stale/dry air;
the air system routing the hot stale/dry air to a bottom portion of the evaporator-condensator-dehumidifier;
the evaporator-condensator-dehumidifier humidifying the hot stale/dry air to humid air causing chilling of a substrate evaporative pad surface that wicks moisture from the condensing cool fresh/humid air passing through the top portion in the evaporator-condensator-dehumidifier;
and
the air system routing the humid warmer air out of the air system via an exhaust.
