How does geoexchange work?
Geoexchange systems, or ground source heat pumps, use a series of pipes which are buried either vertically or horizontally near the target building. For heating purposes, water or a mixture of water and antifreeze are circulated through the pipes to absorb heat from the surrounding soil which is then concentrated and transferred to the building. In hot weather, the process is reversed with the loop carrying heat from the building to use the ground as a heat sink.
Unlike air source units, geoexchange systems do not need defrost cycles nor expensive backup electric resistance heat at low outdoor air temperatures. The stable temperature of a ground source is a tremendous benefit to the longevity and efficiency of the compressor.
Essential Innovation Technology’s customer advantage is that it offers both design and management of the geoexchange loop.
In the installation phase, Essential Innovations Technology will tailor each system based on the needs of customers. Sophisticated computer software programs are used to calculate the size of the loop based on the heating and cooling requirements of their homes, soil conditions and their climate.
Essential Innovation Technology’s geoexchange loops, a series of high density, polyethylene pipes buried in the ground/water and connected to the GeoExchange unit, may be closed or open as determined by the customer’s needs. Furthermore, geo-fields may be horizontal, vertical, or pond/ocean.
Horizontal: Placed in trenches, usually require about 1/3 of an acre of available space
Horizontal Geo-Field
Vertical: Inserted into bore holes, usually require 30 ft. by 30 ft.
Vertical Geo-Field
Pond: Placed at the bottom of a pond or lake, require the pond surface area of at least 1/2 an acre, and minimum 8 ft. deep.
Ocean: Placed at the bottom of the ocean
Pond/Ocean Geo-Field
Open loop systems: Use well or ocean water.
GeoExchange units using well-water require about 5-12 gallons of water per minute, whenever the unit is running. After the water runs through the unit, it is discharged into a ditch, field tile, stream, pond or another well. The ONLY change to the water is a few degrees of temperature difference.
