Method and apparatus for controlling the temperatures of asphalt bodies and concrete bodies

Claim 3

The method according to claim 1, wherein said heat channels are divided into a plurality of lengthwise zones and wherein an adapter element is introduced to said heat channels, said adapter element comprising a plurality of inner tubes through which said heat transport medium is circulated, at least two of said inner tubes opening in opposite ends of each of said zones to permit circulation of said medium from said tubes to said channel and back into said tubes, each of said zones being defined by an upper and a lower sealing cross partition wall to thereby permit selective heating of a zone in said channel.

Claim 4

The method according to claim 2, wherein said plurality of said channels are drilled parallel to each other, and wherein said channels are connected to a control means, said control means selectively directing said heat to or away from said drilled channels.

Claim 5

The method according to claim 2, wherein said inner tubes are wrappingly engaged by a spiral band, said band further engaging the inner wall of said channel, said band sealingly engaging said tubes and said inner channel wall to thereby create a spiral channel, said inner tubes having radially outwardly directed openings, at least two of said inner tubes opening in opposite ends of each of said zones to permit circulation of said medium from said tubes to said channel and back into said tubes, each of side zones being defined by an upper and a lower sealing cross partition wall to thereby permit selective heating of a zone in said channel upon circulation of said transport medium along said spiral channel; and said adapters further comprising a temperature sensor in each of said zones and for indicating at a common central unit the temperature of said zones.

Claim 6

The method according to claim 4, wherein said heat transport medium is selectively circulated within said zones so as to provide the highest temperature to said body along its central portion.

Claim 7

The method according to claim 1, wherein said plurality of said channels are drilled parallel to each other, and wherein said channels are connected to a control means, said control means selectively directing said heat to or away from said drilled channels.

Claim 8

A mechanism for controlling the temperature of a ground-supported asphalt or concrete body, comprising: a plurality of heat channels, said heat channels being drilled into the ground at an oblique angle extending under said body and to thereby permit formation of said channels beneath an existing body, said channels being of sufficient length so as to substantially cover the surface vertially beneath said body; said body providing an isolating medium in the direction upwards for the energy stored in the ground, a plurality of first conduits within said body; a liquid heat transport medium for circulation in the liquid state only and within said channels and said first conduits; pumping means connecting said channels and said first conduits and for circulating said liquid heat transport medium therethrough.

Claim 9

A mechanism for controlling the temperature of a ground-supported asphalt or concrete body, comprising: a plurality of heat channels, said heat channels being drilled into the ground at an oblique angle extending under said body and to thereby permit formation of said channels beneath an existing body, said channels being of sufficient length so as to substantially cover the surface vertially beneath said body; said body providing an isolating medium in the direction upwards for the energy stored in the ground, a plurality of first conduits within said body; a liquid heat transport medium for circulation in the liquid state only and within said channels and said first conduits; pumping means connecting said channels and said first conduits and for circulating said liquid heat transport medium therethrough.

Claim 10

The mechanism according to claim 7, wherein said channels are divided into a plurality of lengthwise zone and wherein an adapter element is introduced to said heat channels, said adapter element comprising a plurality of inner tubes through which said heat transport medium is circulated, at least two of said inner tubes opening in opposite ends of each of said zones to permit circulation of said medium from said tubes to said channel and back into said tubes, each of said zones being defined by an upper and a lower sealing cross partition wall to thereby permit selective heating of a zone in said channel.

Claim 11

The mechanism according to claim 8, further comprising a spiral band surrounding said tubes and contacting the inner wall of said channel, said spiral band sealingly engaging said tubes and said inner channel wall to thereby create a spiral channel in each of said zones for circulation of said heat transport medium through said zone.

Claim 12

The mechanism according to claim 7, further comprising a spiral band surrounding said tubes and contacting the inner wall of said channel, said spiral band sealingly engaging said tubes and said inner channel wall to thereby create a spiral channel in each of said zones for circulation of said heat transport medium through said zone.

Claim 13

A mechanism for controlling the temperature of a ground-supported asphalt or concrete body, comprising a plurality of heat channels, said heat channels being drilled into the ground at an oblique angle with said body and to thereby permit formation of said channels beneath an existing body, said channels being of sufficient length so as to substantially cover the surface vertically beneath said body and being divided into a plurality of lengthwise zones; a plurality of first conduits within said body; a liquid heat transport medium for circulation in the liquid state only and within said channels and said conduits, pumping means connecting said channels and first conduits and for circulating said liquid heat transport medium therethrough; an adapter element within said heat channels, said adapter element comprising a plurality of inner tubes through which said heat transport medium is circulated, at least two of said inner tubes opening in opposite ends of each of said zones to permit circulation of said medium from said tubes to said channel and back into said tubes, each of said zones being defined by an upper and a lower sealing cross partition wall to thereby permit selective heating of a zone in said channel; a spiral band surrounding said tubes and contacting the inner wall of said channel, said spiral band sealingly engaging said tubes and said inner channel wall to thereby create a spiral channel in each of said zones for circulation of said heat transport medium through said zones; and said adapters further comprising a temperature sensor in each of said zones for indicating the temperature of said zone at a common central unit.

Claim 14

A mechanism for controlling the temperature of a ground-supported asphalt or concrete body, comprising a plurality of heat channels, said heat channels being drilled into the ground at an oblique angle with said body and to thereby permit formation of said channels beneath an existing body, said channels being of sufficient length so as to substantially cover the surface vertically beneath said body and being divided into a plurality of lengthwise zones; a plurality of first conduits within said body; a liquid heat transport medium for circulation in the liquid state only and within said channels and said conduits, pumping means connecting said channels and first conduits and for circulating said liquid heat transport medium therethrough; an adapter element within said heat channels, said adapter element comprising a plurality of inner tubes through which said heat transport medium is circulated, at least two of said inner tubes opening in opposite ends of each of said zones to permit circulation of said medium from said tubes to said channel and back into said tubes, each of said zones being defined by an upper and a lower sealing cross partition wall to thereby permit selective heating of a zone in said channel; a spiral band surrounding said tubes and contacting the inner wall of said channel, said spiral band sealingly engaging said tubes and said inner channel wall to thereby create a spiral channel in each of said zones for circulation of said heat transport medium through said zones; and said adapters further comprising a temperature sensor in each of said zones for indicating the temperature of said zone at a common central unit.
