HEAT EXTRACTION SYSTEM AND METHOD FOR EXTREME ENVIRONMENTS

Resumen de: US2025314400A1

A tool for extracting heat from a reservoir includes a shoe made of a material that withstands temperatures larger than 500° C., an outer pipe attached to the shoe, an inner pipe located within the outer pipe and forming an annulus with the outer pipe, the inner pipe having a bore, and a flexible connection configured to connect the outer pipe to the shoe so that the outer pipe is allowed to extend and contract without leaking a fluid inside the annulus. The inner pipe and the outer pipe are configured to form an uninterrupted loop path for the fluid, between a top of the annulus and a top of the bore while also allowing the fluid to directly contact the shoe.

Underground Passive Water-Cooling System and Method of Use

Resumen de: US2025314050A1

The present invention is a passive water-cooling system designed to reduce the temperature of water supplied to a home. The system comprises a plurality of interconnected cooling devices, each featuring a hollow, elongated “S”-shaped pipe made of thermally conductive materials, such as stainless steel. The devices are installed underground (i.e., below ground surface level) and connected to the main water supply, forming a sealed, leak-proof reservoir system. As water flows through the system, it is cooled by transferring heat to the surrounding ground. The system may include detachable connections to prevent overcooling in winter and can be integrated with rainwater harvesting systems for enhanced sustainability. The system operates without external energy, providing an energy-efficient solution for delivering cooler water to homes.

Heating, Ventilation, and Air Conditioning System and Method

Resumen de: US2025314394A1

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.
