A system for conditioning air of a building that comprises a conduit buried in a soil proximate the building at a given depth such that a temperature of the soil at the given depth is different from an air temperature of an environment of the building. The conduit has a breathable wall in fluid communication with the soil. The system further comprises a forced air system in fluid communication with the conduit. The forced air system is operable to draw air from the soil across the breathable wall and along the conduit. The system defines a fluid flow path extending from the breathable wall toward the forced air system. A method of operating the system is also disclosed.

The present invention provides improvements for heating and cooling of structures. In the exemplary embodiments reference is made to residential structures though light commercial buildings would be another option. The heat transfer systems of the exemplary embodiments are constructed and arranged as a way to provide supplemental heat transfer for geothermal systems. One improvement provided by the exemplary embodiments relative to current geothermal systems is the utilization of residential wastewater discharge as the heat sink. Another improvement provided by the exemplary embodiments relative to current geothermal systems is the installation method which can be performed at the same time when the geothermal system is being installed. By linking together these two system installations, cost savings should be realized.

An environment-controlled multi span structured greenhouse comprising a roof, four sides, a release blower equipped with a heating module in relatively cold weather geographical locations, and equipped with a cooling module in relatively hot weather geographical locations, a capture blower, a release blower, a release manifold, and a capture manifold for low cost of supplementary heating and cooling of the greenhouse air, obviating burning fossil fuels thereby reducing global warming, wherein the external surfaces of the roof and the external surface of at least one side of the greenhouse comprise a light diffusing film on predetermined areas and locations thereof together with a thermal shading film affixed to the surface areas not comprising the light diffusing film, and wherein the greenhouse further comprises a mechanized module for adjusting the height of artificial light source and a module for melting snow

A building may include a floor, a dome having a vent, and an internal ceiling that divides areas underneath the dome into first and second chambers. The internal ceiling may have an aperture that is structured to allow air to pass from the first chamber into the second chamber. The building may also include an air inlet configured to allow air to travel from outside the building into the first chamber and an air moving device that is configured to facilitate the movement of the air. The building may also include an air cooling element that is configured to cool the air as it travels from outside the building into the first chamber.

A thermal-energy exchange and storage system has a borefield with a core zone and at least one capacity expansion zone. Each of the core zone and the at least one capacity expansion zone have a plurality of boreholes. The at least one capacity expansion zone is positioned outwards from and encircling the core zone and each additional capacity expansion zone is positioned outwards from and encircling the previous capacity expansion zone. A heat source is provided in fluid communication with a heat exchanger. An injection system circulates an operating fluid. The injection system has at least one U-tube installed within the plurality of boreholes and operating fluid is circulated between the at least one U-tube and the heat exchanger for transferring heat from the heat source. An extraction system is provided for extracting heat stored in the system for use in an infrastructure.

An induced groundwater flow closed loop geothermal system provides safety associated with closed loop geothermal systems (e.g., no mixing of surface water, closed system fluid, and groundwater) and efficiency associated with open loop geothermal systems (e.g., increased heat transfer provided by groundwater flow). A heat exchanger connected to an external system is located in a hole in a geological formation. The hole has a depth below where groundwater is located. A fluid from the external system is routed through the heat exchanger. A pump is utilized to induce groundwater flow from the geological formation, across the heat exchanger and back to the geological formation to enable thermal transfer between the fluid and the groundwater and the groundwater and the geological formation. A casing may be located in the hole to provide structural support and grouting materials may be used to fill space around the casing enabling a groundwater flow path.

The present disclosure proposes a method for when the Heating, Ventilation, and Air Conditioning (HVAC) is called for by a thermostat, the GeoFlo HVAC System first exhausts a heat sink in the basement, before calling for an evaporator to be activated. When the heat sink in the basement is cooling the conditioned space, by geothermally dispersing heat into the earth, the GeoFlo HVAC turns off the evaporator. Alternatively, the system acts as a substitute for an AC evaporator. Variations of the GeoFlo HVAC system and a control box designed to move heat from one area of a building to another using the existing HVAC system are also disclosed.
