Abstract
An air ventilation system for geothermal heating and cooling of an interior of a building, has piping that includes: an outdoor air inlet; a geothermal ground loop embedded in earth below a ground surface adjacent or below the building and having a ground supply line and a ground return line; a flow control device in the piping; a bridge line between the ground supply line and the ground return line; a building supply line connected to the ground return line and configured to distribute air throughout the interior of the building; a building return line configured to return air from the building; and an exhaust air outlet connected to exhaust air from the building return line.
Claims20
An air ventilation system for geothermal heating and cooling of an interior of a building, the system comprising piping that includes:
- an outdoor air inlet;
- a geothermal ground loop embedded in earth below a ground surface adjacent or below the building and having a ground supply line and a ground return line;
- a flow control device in the piping;
- a bridge line between the ground supply line and the ground return line;
- a building supply line connected to the ground return line and configured to distribute air throughout the interior of the building;
- a building return line configured to return air from the building;
- and
- an exhaust air outlet connected to exhaust air from the building return line.
A method comprising:
- supplying air from an outdoor air inlet to a manifold that feeds both a building air ventilation system and a geothermal ground loop;
- operating in a ground recirculation mode where recirculation of air is permitted through the geothermal ground loop and into the building air ventilation system;
- and
- exhausting air from the building air ventilation system after the air passes through the building.
