Method and System for Forming a Non-Circular Borehole

System and methods for creating shaped, non-circular boreholes in rocks especially for use with geothermal heat pump applications and for increasing wellbore support in applications such as horizontal oil and gas drilling are described. The systems and methods when applied to geothermal heat pumps create an elliptical shaped hole that is optimized for placing heat transfer tubes with a minimum of grout used. The significantly reduced cross-sectional area of the elliptical borehole also increases the overall drilling rate in rock and especially in hard rocks. In horizontal hard-rock drilling, creation of a horizontal non-circular borehole or modification of a circular borehole to a non-circular geometry is used to stabilize the borehole prior to casing insertion, and may also allow the use of lower mud pressures improving drilling rates. The system uses a non-contacting drilling system which in one embodiment uses a supersonic flame jet drilling system with a movable nozzle that swings between pivot points. In a second embodiment the elliptical shaped hole is created by an abrasive fluid or particle bearing-fluid or air jet drill that moves between pivot points. In another embodiment a non-contacting drill can use dual parallel nutating nozzles that create a pair of overlapping circular holes. The non-circular shaped hole is created by either the high temperature flame or water-particle jet or chemically active fluid jet as it removes rock material by erosion, dissolution and or thermal spalling. Modifications of circular boreholes to a generally elliptical shape can also be done using milling or jetting techniques.

Optimizing the efficiency and energy usage of a geothermal multiple heat pump system

A system and a method for operating the system is provided to optimize heat exchange between a geothermal loop and a heat pump load loop for heating and cooling a structure. In the method, the flow rate through the earth loop is adjusted based on current thermal demand of a heat pump array, so as to reduce the electrical demand of the earth loop circulator when thermal demand from the heat pump loop is low. The method adjusts the speed of the earthloop circulator as required for the operating conditions of the heat pumps and earth loop, thereby permitting efficient laminar flow whenever possible, as long as thermal demand is met.The system of this invention provides a compact module containing a suitable digital data receiver and controller programmed to receive temperature and flow data and to calculate the needed flow in each loop to meet the thermal demand of the heat pump or pumps, and to signal the earthloop pump, and optionally a load loop pump, to operate at the necessary flow speed. Specifically, if flow in the earth loop transitions from turbulent to laminar, this method insures that the current thermal demand of the heat pumps is met, and if not, increasing the earth loop circulator speed to deliver the current thermal demand of the heat pumps.

Air conditioning system using ground heat

Provided is an air conditioning system using ground heat. The system includes one or more indoor units, at least one outdoor unit, a ground heat exchanger, and a plurality of auxiliary heat sources. The one or more indoor units condition indoor air. The at least one outdoor unit communicates with the indoor units via a plurality of pipes, and includes an outdoor heat exchanger where heat exchange occurs. The ground heat exchanger is connected with the outdoor heat exchanger of the outdoor unit, and laid under the ground to allow heat to be exchanged between ground heat and a circulating medium circulating through the ground heat exchanger. The plurality of auxiliary heat sources are installed on one side of the outdoor unit to assist heat exchange of the outdoor heat exchanger. Two or more auxiliary heat sources are simultaneously used, or one of them is selectively used.
