Description
Technical field
The present invention relates to utilization, relate in particular to a kind of system low energy, in this system by such as terminals such as heat pump from soil, rock or water via the medium fluid transporting heat energy.
Background technology
Here low energy refers to low-temperature heat source, and the temperature of this low-temperature heat source can be for example+2 to+10 degree.In this manual, be called as low energy by the underground heat of supplying with such as thermals source such as soil, rock or water.Utilization to low energy such as soil, rock or water generally is by for example heat pump or thermal energy collecting loop building or service water to be heated.The operation principle of this geothermal system is similar to the principle of freezer unit, and is only reverse, so this system cools soil and add the hot water accumulators for instance.Usually, electric energy unit of every consumption just can obtain two to four hot cells.Usage factor is obviously than directly good with electrical heating.In the frigid zone, the heat energy of house property consumption is quite high.Along with increasing of electric power and fuel cost, utilize underground heat to become more and more favourable.
This low power range system can also be used for inner cooling alternatively, for example via cooling tube etc. medium fluid is circulated from the soil.
A kind of usual way that reclaims heat energy is the pipe-line system of horizontal setting in about 1 meter degree of depth.Yet this pipe-line system needs very large tracts of land, so it can only be used in the large tracts of land place.This collecting loop can be underground or in water.Need excavate the pipeline raceway groove of the whole area that is used for collecting loop in the pipe-line system of underground arrangement level.At least 1.5 meters of the necessary each intervals of the pipe-line in this loop, thus make adjacent pipe-line can not hinder energy recovery each other.Be difficult to avoid damaging the root system of plant and trees when for example, horizontal pipe being placed in the park.
Second kind of usual way that reclaims heat energy is geothermal well.Here, pipe-line system is embedded in the hole that gets out on the rock.Geothermal well-be that drilling well normally vertically gets out.With respect to horizontal pipe system, the required area of geothermal well is very little.Yet, more than rock, have the quite dark cover layer of tens of rice.Tectal part must be provided with protection tube, has so just increased cost.Therefore, has the arrangement that has limited geothermal well than the soil of thick-covering.Thermal yield in the geothermal well is generally greater than the thermal yield in the horizontal pipe system.The thermal yield of geothermal well depends in part on subsurface flow.Yet not carrying out expensive probing is impossible judge subsurface flow.
The third usual way that reclaims heat energy is to settle the energy recovery pipe-line system at lakebed or another kind of water channel bottom, thus heat energy is transferred to medium solution from basic sediment and water.Pipeline can be placed in the water in the soil, but in this case must be with the tunnel of the tunnel of supply pipe and return duct separately.It is easy placing the pipe-line system of water in the installation of water channel bottom.Yet the pipeline that is full of solution is lighter than water, so it tends to upwards float.The pipe section that floats may cause the air pocket that hinders circulation.Therefore, pipeline must be anchored on the bottom with the weight of sufficient amount.The pipe-line system that is placed in the bottom is also held 0 easily fragmentation.The anchor of boats and ships etc. may block pipe-line system and pipeline is damaged.In the waterside, supply pipe and return duct must be dug into the bottom, thereby make ice can not damage pipe-line system.
Yet the position in used place, area and soil are depended in the selection of these three kinds of modes.The low energy networking is designed to implement by this way: a shared bigger thermal energy collecting loop, stove room room even.

Another object of the present invention provides a kind of pipeline of implementing terminal low energy receiving loop.
According to the embodiment of one object of the present invention, described system comprises terminal and ground circuit, and wherein, the heat that passes to the medium fluid that circulates in this loop is transferred to the heating circuit of house property by for example terrestrial heat pump.This ground circuit is provided with internal pipeline and by this way around the external pipe of this internal pipeline: make the outer end of described external pipe seal, thereby this medium fluid according to the difference of flow direction and in the end of described pipeline internally pipeline move to external pipe, perhaps move to internal pipeline from external pipe.
The ground circuit of described system can be by for example being dug into it the level of being arranged in the raceway groove.Allow there not be the described loop of enforcement under the situation of reflux line independently according to pipeline according to the present invention.The channel length of excavating for ground circuit reduces according to the area of external pipe outer surface.
Described pipeline can be by being arranged on underground from the oblique boring down of ground level.Because do not need to be used for the independent tunnel of the reflux line in described loop, hole so not only can land used be drilled on the rock, and can land used be drilled between rock and the soil and hole.Pipeline according to the present invention makes described pipeline can be placed in the water channel below, states pipeline in this place and is protected.The hole that is used for described pipeline is to drill out under oblique, and the outer end of described pipeline can be placed in more depths, and the temperature at this place is also higher.Described pipeline is tilted to down makes air to discharge from described pipe-line system.The gradient of described pipeline changes according to soil.Described pipeline needs not to be straight, and can be along with soil hole situation and crooked or bending.Because do not need independently reflux line, so pipeline according to the present invention allows ground circuit to be arranged on water channel, park, road or or even building below.
According to second embodiment, ground circuit comprises the main pipe system that is connected to terminal, and two or more described pipelines with internal pipeline and external pipe are connected to described main pipe system.Described main pipe system can be arranged to autonomous system, but in this case must be by described pipeline is separated from one another or make that the trunk line of carrying the medium fluid be heated is adiabatic to minimize the heat transmission.The quantity of described pipeline and length can change according to employed area and soil.Should be pointed out that and be not only, and the ground circuit of implementing in a usual manner can both be connected to described main pipe system according to pipeline of the present invention.
The embodiment of second purpose according to the present invention, medium transfers out from heat pump in the internal pipeline of described pipeline, wherein said pipeline comprises the internal pipeline in external pipe and the described external pipe, and heat pump is from receiving medium fluid through the underground heat heating between the outer surface of described internal pipeline with around the space between the inner surface of the described external pipe of internal pipeline.Oblique down or in the hole that gets out downwards straight, its temperature is higher than the temperature of the end of described pipeline.Cold as far as possible medium transport is arrived lower position, thereby maximum possible temperature difference between the exterior materials of described medium fluid and described pipeline is provided at place, the end of described pipeline, and exterior materials is for such as soil, water or be positioned at the packing material etc. of described pipeline outside.Big temperature difference makes heat energy be transferred to medium efficiently.
According to an embodiment of the invention, described pipeline comprises internal pipeline, and the outer setting of internal pipeline has the external pipe part that is separated by recess, and described external pipe partly forms external pipe.Owing to be provided with the female portion in it, therefore described external pipe provides the bigger area that energy is transferred to medium solution, because energy also can be by the sidewall transmission of the female portion.Bigger area is to utilize the phase place variation of the material of described pipeline outside to provide good starting point.The described material of described pipeline outside can be freezing or be melted, and promptly is converted into solid from liquid, otherwise perhaps.Further, the female portion makes that described pipeline can be crooked, and can not make the shape of described pipeline be unfavorable for realizing its function.Described pipeline does not have the easier bending of coaxial pipes of recess than the periphery.Preferably, with reel that manufacturing is associated on make described pipeline, so it still has temperature thereby easier bending.Heating makes that described pipeline is easier and unclamps from described reel.Described pipeline can assign to heat by for example warm liquid being transported to two pipe section, carries out bending easilier thus.Since have the female portion, therefore can be by coming internal pipeline is heated from the described pipeline of external heat.According to another embodiment of the present invention, described pipeline comprises external pipe, and internal pipeline can be arranged in the inside of external pipe.By means of the recess that is arranged in the described external pipe, the inner surface that the outer surface cloth of described internal pipeline is set to described external pipe separates.The female portion can be the part with given shape of external pipe, and it makes internal pipeline aim at the external pipe center.And the female portion makes described pipeline can not cause the shape of described pipeline to be unfavorable for realizing its function when bending.The end of described pipeline is arranged to hold the end cross-sectional of sealing described external pipe end by this way: make the medium fluid of carrying in described pipeline to move to described external pipe in described end from described internal pipeline according to the difference of flow direction, perhaps move to described internal pipeline, thereby be arranged to the thermal energy collecting loop from described external pipe.Sealing to described pipeline can be implemented in every way according to rig and method.Yet, should be appreciated that described end cross-sectional only seals the end of described external pipe, so described solution can move to another pipeline from a pipeline.Otherwise the shape of for example utilizing end cross-sectional makes fluid be directed to external pipe or can simplify the transmission of medium fluid from described internal pipeline.
For example, the material of described pipeline is a polyethylene.The diameter of described external pipe for example is 100 millimeters, and the diameter of described internal pipeline for example is 40 millimeters.In this case, the periphery of described external pipe is greater than described internal pipeline, owing to wherein be provided with the female portion, energy can be transferred to described medium solution by bigger area.
Capacity between the inner surface of the described external pipe relevant and the outer surface of described internal pipeline with the capacity of described internal pipeline can be by changing described pipeline natural scale and the quantity and the shape of recess increase.Preferably at least three of the quantity of microscler recess, internal pipeline can be placed in the external pipe with one heart thus.The recess of described external pipe can also thread-like manner be implemented, and the flow channel that is formed on thus between the female portion becomes longer than the flow channel of linear pattern recess.When recess was arranged in the described pipeline with thread-like manner, the female portion that lesser amt is set just can realize the center of external pipe is aimed at internal pipeline.Aim at internal pipeline even can implement with a recess with fine thread.Equally, the screw-shaped technical scheme can be implemented by this way as single-piece and two part pipeline configuration: promptly make described pipeline be convenient to bending by recess.
