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.

A ventilation system applies geothermal temperature stability for ventilation of air in facilities near outdoor spaces. For example, there are a large number of wastewater treatment facilities built or renovated each year, with significant work on ventilation. The ventilation system therefore has significant potential for application and improvement of infrastructure.

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.

Through a power cable from a power collection box, a power conversion device receives DC power. The power conversion device converts the received DC power into AC power and transmits it to a power system. A plurality of air lead-in tubes are laid in parallel. Each of the air lead-in tubes includes a heat exchange part, an opening part, and a lead-in part. The heat exchange part is buried in a ground at a ground surface on a back surface of a solar cell panel. The opening part is exposed to the ground surface. The lead-in part is an opening that communicates with an interior of a building in which the power conversion device is installed. The air lead-in tubes are constructed to draw air in the heat exchange part from the lead-in part by using a sucking mechanism.

Convection-enhanced thermal insulation and central air conditioning capable of maintaining a comfortable indoor environment at reduced energy consumption is provided. A siding system comprises a first duct and an air passageway. The first duct has a first end thereof disposed in an underfloor space of a building, and a second end thereof disposed either on a ceiling or in a ceiling space of the building. The air passageway sends air from the underfloor space of the building to the ceiling or the ceiling space.

An indoor cooling system kit can include aluminum beverage cans, flexible hoses, a fan, and instructions for forming the indoor cooling system. Further kit materials can include containers, dehumidifying material, a filter, and further instructions. A method of cooling an indoor region can include cutting tops and bottoms away from aluminum beverage cans, coupling the cans together in series to form two elongated airflow passages, coupling a flexible hose to open ends of both airflow passages, adjusting the hose so that both airflow passages and hose form a U-shaped airflow passage, forming a hole in the ground beneath the indoor region, inserting the U-shaped airflow passage into the hole with its inlet and outlet elevated out of the hole into the indoor region, and operating a fan to force air through the inlet. The air is cooled geothermally as it travels through the overall U-shaped airflow passage.

One embodiment of LMHPs, as shown in FIG. 10, is a multi-function, grid-interactive heat pump system by alternately charging/discharging thermal energy storage (40) as its heat pump source. The charging process maintains thermal stability to the source. The thermal stability of the source ensures high system performance, and this energy-storage-as-source and its effective use provide system operational versatility. Which takes the forms of availing the system-operation of dual heat sources (10 and 20) for heating application, demand-response management (48), grid-integrated water heating (46) as well as grid-integrated space heating and cooling (48). By transcending the limitations of individual, stand-alone, solar units and heat pump units, the grid-interactive heat pump system performs heating function better than all existing heat pump methods. LMHP principle is applicable to single-function, grid-interactive heat pump operation with similar benefits of high performance and demand-response management. Other embodiments are described and shown.

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.

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.
