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.

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 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.

A thermal system includes a first facility fluid circuit including a facility fluid for circulating through a facility, a first facility heat exchanger, and a first facility supply inlet for providing the facility fluid to the facility. A second facility fluid circuit includes the facility fluid, a second facility fluid heat exchanger, and a second facility supply inlet. A ground-source heat pump includes the first facility heat exchanger and is associated with the first facility fluid circuit. An air-source heat pump includes the second facility heat exchanger and is associated with the second facility heat exchanger. A mutual supply duct connects the first and second facility fluid circuits such that the first facility fluid circuit is fluidly connected to the second facility supply inlet and the second facility fluid circuit is connected to the first facility supply inlet.

Disclosed herein is an air cooler including a housing having an upper portion and a lower portion. The upper portion of the housing includes an air intake, an air output, and a manually operated fan. The lower portion of the housing includes an air passage leading from the air intake to the air output. The air passage may include baffles that cause air to travel laterally. The air cooler is particularly designed for use on a playground.

A temperature control system (TCS and a subsurface intake assembly for a TCS for a building are provided herein. The subsurface intake assembly includes one or more subsurface intake units disposed within the ground and configured to receive subsurface air. An intermediate connection assembly receives the subsurface air from the intake units and directs the subsurface air to the TCS. In order to collect the subsurface air, each of the subsurface intake units include one or more openings into which the subsurface air can flow. In this manner, the subsurface air flows from a location external to the subsurface intake unit, into the subsurface intake unit through the one or more openings, to the intermediate connection assembly, and eventually to the TCS.
