Background technology

In the discussion of following background, with reference to some structure and/or method.Yet, below quote should not be interpreted as and admit that these structures and/or method constitute prior art.The applicant clearly keeps and shows that this structure and/or method should be as the rights of prior art.

Environment temperature and the cambium reale energy of subterranean heat exchanger through utilizing the soil, depths.The present heat exchanger that degree of closeness through suitable water body, underground reservoir, land surface, depths temperature and/or ground condition define the nominal ton of every heating and/or cooling requires and disposes.In many local-style dwelling houses and commercial facility, because present technical limitations, land surface, geological conditions or only forbidden using the chance and the selection of this renewable resource owing to cost.In the application of subterranean heat exchanger, need reduce the required real area of installation through increasing efficient, and make system can be used in the new building and the existing building of bigger percentage.

The global utilization rate that is used for source, the ground energy of heating and cooling increases.The use of subterranean heat exchanger system or technology is indispensable to the function of these systems.Exist to utilize to be included in and stay the multiple structure and the method for depositing energy in the soil.Instance comprises: (i) utilize from the water of well, pond, river, lake or ocean exchange; The array of the closed loop pipeline of (ii) laying with coiling or bend mode, or be immersed in water body or imbed other system that constructs like this face of land in; (iii) be embedded in a series of loops in the adit in the ground; And (iv) get out on ground vertically or the hole that tilts, said hole comprises the closed loop pipeline, the degree of depth place that this pipeline will be recycled to boring based on the hot fluid or the compressor reducer fluid of water, and make it to turn back to the surface of boring.

The development of recent years has improved based on water and the efficient that directly exchanges heat pump, and these all influence the designing requirement that the soil connects heat exchanger.Progress on the forecasting software program is also through guaranteeing that demand load to the building that will serve of institute suitably calculates size that ground connects heat exchanger and changes required area with efficient heat and increased efficient.The instance of this software must provide suggestion with the linear feet number of another amount of space that separates of boring and required boring for each boring.Perhaps, this program can provide the requirement that connects other instance of heat exchanger and open system to ground.

The instance that is used for installing the boring heat exchanger is included in that face of land Drilling goes out, vibrates, drilling goes out, get out, hammering goes out or eject boring, makes it to separate specified distance, and connects with various collectors and gathering system.Owing to distance and interval that each boring is separately needed with the thermal communication that prevents its efficient of meeting reduction between them, every kind of pattern in these Installation Modes all can need a large amount of floor area.This can cause using the future of floor area problem, and is enough dark because supply and gathering line will just in time locate below ground level, to reduce the effect that the seasonal surface temperature of short-term changes and influences, promptly common below ground 2 to 8 feet.Another selection is from ground or at the level height that is lower than the effect that changed by seasonal surface temperature and influence Drilling diagonally, the azimuth is about 30 ° to 85 °, and begins each boring in the ground original position near other boring.This is called as pad and bores (pad drilling).This face of land that keeps the place, ground to be damaged drops to minimum.Yet, because the thermal convection current between all boring needs more boring.Note also adjacent ownership or adjacent right that the boring at ultimate depth place does not hinder floor area ownership pipeline to be limited.The boring placement that most of jurisdictions all have rules to manage and hole required for contiguous adjacent ownership hinders (setback).

Regardless of hole towards; After one or more hot fluid feed-lines have inserted boring; Carry out pressure test to guarantee the pipeline integrality, the remainder of each boring is filled with the various materials of the grouting from water to the special configuration, and target is to eliminate all idle spaces and sealing boring.The different formulations of grouting has the design effect that increases the thermal conductivity between hot fluid, pipeline, grouting and the peripheral ground.The thermal conductivity that increases interior hot fluid of pipeline and peripheral ground will improve the energy transmission as those skilled in the art are known.Usually be used for the pipeline of the hot fluid feed-line in the heat exchanger with the polyvinyl piping materials conduct, said pipeline circulates in closed loop based on the hot fluid of water, and this hot fluid is made up of water and optional antifreeze and antirust agent.

Another closed-loop system direct cycles to subterranean heat exchanger with compressed fluid through the pipe that is made of copper usually.Utilize the system of this pattern to have than the efficient of circulation based on the higher every linear feet heat exchanger of the polyvinyl piping materials of the hot fluid of water.These systems are called as DX or direct switching system.Copper has the energy conduction performance higher than plastics, so thermal energy transfer is more efficient.Under any situation, hot fluid through the subterranean heat exchanger looped cycle and heat up naturally or the liquid transfer of cooling to another heat exchanger that is positioned at ground, this another heat exchanger is used for receiving heating usually and/or cools off in building.This is a kind of in several kinds of energy heat exchanges that can take place.

Another conventional boring selects to use the coaxial configuration of pipeline or conduit; The fluid that gets into boring thus can advance to bottom or the far-end on the outside of pipeline, conduit or sleeve pipe; Get into separate chambers effectively, and turn back to the original position of same pipeline internal drilling then.Flowing can be according to heating or cooling and reverse.Another coaxial configuration has at main pipeline, conduit or inside pipe casing or outside feed-line of advancing with the helical mode.For a person skilled in the art, exist motion that many instances and structure introduced hot fluid in detail at the near-end of boring or section start begins to the bottom or far-end and return ground.

In having the routine boring heat exchanger of vertical part, hot fluid advances to or near foot of hole, and returns the surface of same boring then.Conduit or pipeline can separate through being designed to keep various holders that pipeline separates or distance piece or coaxial chamber, to reduce from fluid that gets into boring and the thermal energy transfer of leaving the fluid of boring.In some instance, can make one or more pipeline insulation of delivery hot fluid.But,,, still have the heat transmission of energy because the pipeline that gets into foot of hole returns pipeline approaching on ground with making hot fluid in any case make great efforts to make fluid that gets into subterranean heat exchanger and the fluid isolation that flows out subterranean heat exchanger.

In industry, still need such method and apparatus so that hot fluid moves through the boring heat exchanger in the various structures, its eliminated far-end pipeline and nearly depot siding closely near, this improves the energy transmission between soil and the hot fluid.The result is the energy transmission that same amount need boring still less be provided.This technology also will reduce installation cost, and will reduce the required land size of boring " place ", can select to utilize simultaneously ground system of connections service more owners, facility and mechanism.

The specific embodiment

Fig. 1 illustrates the example embodiment of the underground continuous loop heat exchanger with boring that institute's Drilling goes out in passing the continuous loop on the face of land.Underground continuous loop heat exchanger 10 comprises boring 12; Boring 12 comprises inlet 14 that is positioned at first end, 16 places and the outlet 20 that is positioned at second end, 22 places; At first end, 16 places; Boring 12 is opening at the primary importance place, for example in the stratum that is used to the system that imbeds 18 or the surface that is used for the stratum 18 of ground system be face of land upper shed, at second end, 22 places; Boring 12 is 18 second place opening on the stratum, for example in the stratum that is used to the system that imbeds 18 or the surface that is used for the stratum 18 of ground system be face of land upper shed.It is enough dark that boring 12 major part is positioned at face of land level height 24 belows that are easy to influenced by seasonal temperature, promptly usually below the ground 26 between two to eight feet.The pipeline 28 (illustrating with cutaway view) that is used for fluid is positioned at least a portion of boring 12.In the exemplary embodiment, pipeline can be pipe or the conduit of being processed by synthetic material, metal or metal alloy, and it can have the coating that is made up of materials similar, material different or combination of materials on all or part of of inner surface or outer surface.

Fig. 1 illustrates the system of imbedding, and this is imbedded that system has first end 16 of stratum 18 internal drillings 12 and before for example turning with symmetric mode or identical radian, 26 marches to the degree of depth (D) from ground, and 26 returns towards ground at second end 22, to end at stratum 18.Working depth (the D of subterranean heat exchanger _w) being easy to of being measured as that boring extends to receive the degree of depth of face of land level height 24 belows of seasonal temperature influence.

Shown in exemplary embodiment in; First end 16 is inlets; And second end 22 is outlets, but entrance and exit can exchange as required, to promote to be used for the pipeline 28 of fluid and being operatively connected of supply pipeline that leads to earth source heat pump or heat exchanger system 38 34 and return line 36.In an example, earth source heat pump 38 itself may be operably coupled to building 40 to regulate temperature or other ambient parameter of building 40.In Fig. 1, earth source heat pump 38 is positioned at the ground of building 40.

Inlet 14 was opened preset distance (D in 20 minutes with outlet _s).Preset distance be chosen to make the heat at inlet 14 places of boring 12 go along with sb. to guard him district 42 and boring 12 to go along with sb. to guard him district 44 in outlet 20 place's heat independent basically.Heat shown in broken lines is gone along with sb. to guard him the district among Fig. 1.In Fig. 1, preset distance (D _s) big, and obviously do not have heat to go along with sb. to guard him the overlapping of district at the respective end place.

Fig. 2 illustrates the enlarged drawing of second embodiment of underground successive heat exchangers 10, wherein enters the mouth 14 to open much little preset distance (D in 20 minutes with outlet _s).In Fig. 2 embodiment, it is not overlapping that inlet 14 and outlet 20 corresponding heat are gone along with sb. to guard him

district

42,44, goes along with sb. to guard him district 42, distance of separation (D between 44 like corresponding heat _E) that kind that obviously illustrates.Suitable preset distance (D _s) instance be at least about 25 feet, perhaps at least about ten feet, perhaps at least about three feet, perhaps between about three feet to about ten feet, perhaps between about three feet to five feet.In instance shown in Fig. 2, can find out, at preset distance (D _s) locate, heat is gone along with sb. to guard him the distance of separation (D in district 42,44 _E) greater than zero, preferably at least greater than about one foot, perhaps at least greater than about three feet.

The reason that boring has the linear range of the qualification that they are separated is thermal convection current and heat conduction between the compensation boring, and guarantees to exist the area that is enough to make the regeneration of boring peripheral ground temperature natural.When just energy being removed or during injection hole, the stratum will be heated up or cool off in time on every side.For example, when the fluid colder than the intermediate value temperature in soil cycled through boring, the stratum was gone along with sb. to guard him interior zone, district through heat hot and has been replaced the energy of removing from the face of land on every side.This thing happens in meeting when local source heat pump moved with heating mode.If boring too is close together at degree of depth place or is too short, then hole and the soil between or the energy transmission meeting between soil and the boring carry out with the speed higher than the adaptable speed in soil, and can cause near the surface temperature of hot fluid temperature balanced.Under the situation that abuts against very much isolated boring together, boring between and thermal communication takes place between nonthermal source and the heat dissipation equipment.The thermal efficiency that this can cause boring in this zone, to reduce, this finally causes equipment weight, inefficiency or sudden failure.In order to compensate the boring that tight spacing is opened, a kind of selection is to get out more to hole or increase the linear degree of depth, and this can increase cost.

Preset distance (D _s) can be according to application change; And be chosen to be suitable for wherein locate the characteristic on the stratum of boring, the size in place; And/or based on building 40 burden requirement wherein, the temperature that earth source heat pump of being served through underground continuous loop heat exchanger or heat exchanger system are regulated building.For example, under the situation of inapplicable distance limit, at preset distance (D _s) quite big, for example, can select structure such as the boring shown in the example embodiment 12 among Fig. 1 in tens of or hundreds of footage magnitudes or under at least about 15 feet situation.But, in another example, under the situation that is suitable for distance limit, at preset distance (D _s) quite little, for example at 1 foot or be not more than under 10 feet the situation, can select structure such as the boring shown in the example embodiment 12 among Fig. 2.In second instance shown in Fig. 2, it is roughly vertical at the entrance and exit place to hole, and this realizes through forming boring with the directional drilling device that further describes like this paper.

In other instance, for little, for example less than ten feet, or less than 55 feet preset distance (D _s) boring and for little, for example less than ten feet, or less than five feet, also or less than two feet distance of separation (D _E) corresponding heat go along with sb. to guard him the district, it is roughly vertical at the entrance and exit place need not hole.For example and as among Fig. 3 with shown in the perspective cut-away schematic view; The example embodiment of underground successive heat exchangers 10 can have non-vertical and non-horizontal drilling 12 towards; It has inlet 14 and outlet 20, and have little, for example less than ten feet, or less than five feet preset distance (D _s) and have also for little, for example less than ten feet, or less than five feet, go along with sb. to guard him the distance of separation (D in

district

42,44 also or less than two feet corresponding heat _E).In the embodiment shown, at least in part through 12 the inclination of holing towards having realized distance B with its loop structure that is similar to teardrop _s, D _ELittle value, but also can utilize other towards and loop structure.

Fig. 4 illustrates the example embodiment of the boring 12 that is positioned at building 40 belows.In this example embodiment, inlet 14 is positioned on the not homonymy of building 40, on opposite side or sides adjacent with outlet 20.On the contrary, the exemplary embodiment of the boring 12 in the underground continuous loop heat exchanger 10 is positioned at the same side of building 40 among Fig. 1.All the other feature classes shown in Fig. 4 are similar to shown in the exemplary embodiment of the boring 12 in the underground continuous loop heat exchanger 10 among Fig. 1 and described characteristic.

In the example embodiment of underground continuous loop heat exchanger 10, be unidirectional with respect to boring 12 fluid flow direction.That is, the fluid through pipeline 28 flows (F) only along a direction, gets into and advances towards second end 22 from 12 first end 16 of holing.In addition; Fluid flow (F) be in the continuous loop, that is: with respect to boring 12 from first end 16 along a direction after second end 22 is advanced, fluid returns first end 16 (through for example earth source heat pump 38) through port then; At first end 16, fluid gets into from first end 16 again.

In example embodiment, underground continuous loop heat exchanger 10 has the boring 12 of most of length right and wrong level, perhaps greater than 75% length right and wrong level, also or greater than 85% length right and wrong level.For example, referring to Fig. 1 and 3.In Fig. 1 and 3, boring 12 have comprise non-level most of length towards.In fact, in these instances, except deepest point 50 places towards, boring 12 from the whole length of first end, 16 to second ends 22 right and wrong level all.

In example embodiment, underground continuous loop heat exchanger 10 has boring 12, and the outlet 20 of wherein hole 12 inlet 14 and boring 12 all has center line 52, and center line 52 is with respect in vertical ± 15 degree, perhaps with respect in vertical ± 5 degree.In other alternate embodiment, boring 12 center line 52 towards continuing with respect to vertically in ± 15 degree, perhaps with respect in vertical ± 5 degree, till boring 12 is darker than frost line 24.The instance of this layout shown in Fig. 1 and 2.In addition and about Fig. 2, the center line 52 of boring 12 up at least 50% the degree of depth of deepest point 50 all with respect to vertically in ± 5 degree.

For promote and stratum 18 between heat exchange, heat exchange medium 60 can be positioned to hole in the annular space 62 (preferably full annular space) between the outer surface 66 of 12 inwall 64 and pipeline 28.Heat exchange medium 60 all is positioned at annular space 62 until face of land level height 24 belows that are subject to the seasonal temperature influence at least, preferably is located in the full annular space, and helps and the heat exchange on stratum 18 on every side.

The instance of heat exchange medium 60 is based on bentonitic heat grouting; Such as can be from geology company (GeoPro, " the Thermal Grout Select " that Inc.) buys and " the Thermal Grout Lite " of the Ai Erkedun (Elkton) of American South Dakotas (South Dakota).At United States Patent (USP) the 6th, 251, another instance of heat exchange medium 60 is disclosed in No. 179, the full content of this patent is incorporated herein by reference.The latter owing to excellent thermal conductivity with reduce characteristic and obtain paying close attention to.Although use the well cementing mixture of cement and bentonitic routine to form good initial sealing, through the variation of combination meeting after a while, make to cause forming the air gap that this significantly reduces the efficient of interchanger.In alternative exemplary embodiment, heat exchange medium 60 can comprise that synthetic material is to strengthen moisture retention.The instance of reinforcing material of preserving moisture is gel additives, such as in oil and natural gas drilling fluid and commercial Application, finding.An aspect of heat exchange medium 60 is polymer, and this polymer contacts with water and forms colloidal materials.The instance of this polymer includes but not limited to the heat conduction solid, such as the sand of being made up of silica or rubble, pearl or powdered glass or metal or metal alloy.Water-soluble polyacrylamide polymer, biopolymer, cluster bean or biogum---but it down is a rehydration in some combination, and when dewatering, does not ftracture.

The example embodiment circulation of underground continuous loop heat exchanger 10 and transmission fluid make the mobile of fluid can produce fluid and heat conversion the most efficiently between the stratum on every side.To be enough to flow corresponding to the volume of about 2,500 Reynolds number and the speed fluid through pipeline generally is the target flow rate for the efficient heat conversion of using subterranean heat exchanger, as well known by persons skilled in the art.Research and test shows; Corresponding Reynolds number is 2; Between 300 and 4,000, like the transition flow velocity that uses in the conventional ground source heat interchanger because the mobile reinforcing member that comprises in the pipeline or replenish the heat conversion of flowing reinforcing member and can experience enhancing through adding.

Optimum in order to ensure flow velocity and flux enhancement parts uses, and the degree of depth of the face of land to earth drilling is analyzed.If adopt, the reinforcing member that then flows makes the thermal capacity on the stratum of carrying one or more borings maximum, and based on selecting when precondition.Be noted that the limit of the heat conversion that is no more than the stratum, but make potential energy (potential) maximum between source, ground and the heat dissipation equipment, as well known by persons skilled in the art.
