초록 ▼

A subterranean ground heat exchange system, a method of installation, and a grout composition therefor. The grout composition is a pumpable slurry formed of from about 70 to about 85 parts by weight natural flake graphite and from about 30 to about 15 parts by weight bentonite. The solids content of the pumpable grout slurry is preferably at least 35% by weight and is more preferably at least 40% by weight. The ground exchange apparatus preferably utilizes an improved supply and return header comprised of supply and return ports which are provided through the vertically extending outer wall of a header housing. The header also includes an interior supply conduit which extends from the supply port into the interior of the header housing and includes a bend positioned in the interior of the housing for directing the heat transfer fluid downwardly.

1. An apparatus for subterranean ground heat exchange, comprising: A casing extending vertically underground a distance of at least 100 feet and having an inside circumference of at least 9 inches, an internal delivery conduit extending into said casing, and a supply and return header mounted underground at an upper end of said casing for supplying a heat transfer fluid into said internal delivery conduit and for receiving said heat transfer fluid as it returns to said supply and return header via a return flow annulus between said internal delivery conduit and an interior wall of said casing, an improvement comprising said supply and return header comprising:A housing having a closed top and a vertically extending outer wall which surrounds an interior of said housing, said closed top defining an upper end of said supply and return header,A supply port for said heat transfer fluid provided through said vertically extending outer wall below said closed top of said housing, said supply port having a horizontally extending end portion of a fluid supply line connected thereto undergroundA return port for said heat transfer fluid provided through said vertically extending outer wall below said closed top of said housing, said return port having a horizontally extend end portion of a fluid return line connected thereto underground, andAn interior supply conduit including a first portion of said interior supply conduit which extends into said interior of said housing from said supply port and has a bend which is positioned in said interior of said housing for directing said heat transfer fluid downwardly and a second portion of said interior supply conduit which extends downwardly from said bend for delivering said heat transfer fluid to said internal delivery conduit,Wherein said supply port and said return port of said supply and return header are positioned elevationally higher than said upper end of said casing but said upper end of said supply and return header is not more than 10 inches above said upper end of said casingWherein the improvement further comprises a collar for mounting said housing on said upper end of said casing, said collar having an upper portion wherein a lower end of said housing is received and said collar having a lower portion wherein said upper end of said casing is received, said lower portion of said collar comprising a socket wherein said upper end of said casing is received for bonding said collar, without threaded attachment, to an exterior upper end portion of said casing.
