AI Technical Summary

Problems solved by technology

However, the system has various flaws and deficiencies
For example, many ground source loops of known systems are expensive, difficult to install, require toxic chemicals and are prone to failure
Additionally, these systems are difficult to service and difficult to expand or expand if additional heating or cooling capacity is needed or desired
These and other factors are generally considered to be the main reasons why current geothermal exchange systems and geothermal resources are not fully utilized

Abstract

A geoexchange system is provided which includes a ground source heat exchanger positioned in the ground and a distribution system coupled to the ground source heat exchanger to circulate water through the ground source heat exchanger during operation. The distribution system may include a supply line, a return line and a circulation pump to circulate water through the internal fluid cavity of the ground source heat exchanger via the supply and return lines. The distribution system may further include a purge valve to release gas from the distribution system and a fill circuit that is configured to automatically replenish the internal fluid cavity of the ground source heat exchanger with water upon leakage of water from the ground source heat exchanger or conversion of water from the ground source heat exchanger to gas. Other geoexchange systems and related methods are also provided.

Description

technical field [0001] The present disclosure is directed to geothermal heat exchange systems including geothermal heat exchangers and related methods of utilizing the earth as a heat sink and / or heat source Background technique [0002] Various geothermal heat exchange systems (sometimes referred to as geothermal systems) are well known, including closed loop systems and open shaft systems. A geothermal heat exchange system can be generalized as a heating and cooling system for an interior space in which the earth is used as a heat source when heating the interior space and / or the earth is used as a heat sink when cooling the interior space. Components of known geothermal heat exchange systems typically include, among other components, heat pumps, ground source heat exchangers, and distribution systems. Many geothermal heat exchange systems utilize air ducts as the distribution system and polyethylene conduits in the ground as ground source heat exchangers. However, this ...
