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

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.

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.
