ABSTRACT:
The geothermal heat transfer system comprises a plurality of heat exchange loops placed in the ground at an angle of less than a 20 degrees, but greater than a 5 degrees. Each loop has an out flow line and a return line, and a fluid tight, tapered end, U-turn juncture connecting the lines. A pair of distributors connects to inlet and outlet lines at a lower end and a plurality of outlet members at the upper end. A heat exchange device connects to the loops through the inlet and outlet lines. A liquid-oil-gas separator uses cup member and deflector to create a Venturi fluid inlet to separate the oil, returning it to the compressor. A bore hole drilling device comprises an hollow drilling bit with a cutting member at one end, a central fluid passage, and connecting means. The bore hole drilling device has a swivel member with a body portion and housing with a central bore and an inlet, connect to a water line. The body is position within the central bore and mounted for rotational motion within the housing.
