US Patent:

57299927, Mar 24, 1998

Filed:

Dec 17, 1996

Appl. No.:

8/766070

Inventors:

Kenneth W. Lambert - Bridgewater VA

International Classification:

F25B 4500

US Classification:

62149

Abstract:

A geothermal heat transfer system having a plurality of heat exchange loops placed in the ground, each loop having an out flow line and a return line connected by a U-turn juncture. A heat exchange device connects to the loops through the inlet and outlet lines. A refrigerant charge control system selectively provides either heating or cooling heat transfer to or from a temperature regulated area. A charge control flow control device maintains a single flow direction of refrigerant within charge control system, while refrigerant flow reverses direction elsewhere in said heat pump system. A plurality of check valves are employed to provide the flow control. A float and stop valve system maintains a sufficient quantity of refrigerant in the condenser and evaporator of the heat pump for optimum design performance.

Inventors:

Kenneth W Lambert - Bridgewater VA

International Classification:

E21B 1000
E21C 2504
E02D 2900

US Classification:

175 62

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.
