Description
Technical field
The invention belongs to the earth source heat pump field, particularly relate to a kind of following pipe arrangement of ground buried pipe of ground source heat pump.
Background technique
Geothermal heat pump air-conditioner is to utilize a large amount of low temperature heat energies of storing in underground, rock, underground water or other the medium for space heating installation, air-conditioning and hot water to be provided.The waste thermal energy that air-conditioning is got rid of during summer is transported to underground, and the heat energy during winter in the soil is extracted, and gives air conditioning and heating.Earth source heat pump is the most comfortable, efficient, environmental protection, energy-conservation technology up to now, is up-to-date in the world, the most high-grade at present air-conditioning and heating system, has obtained using widely.
At present owing to go into the well deeplyer, the slime water in the well is bigger to the buoyancy of tubing in work progress for the used ground pipe laying of geothermal heat pump air-conditioner, under the curved density of the heat exchanging tube that the PE material is processed and U-shaped is far away in the density of slime water; Thereby can not rely on pipe under the gravity, and general way is in the curved intermediate portion of U-shaped one stay bolt to be set at present, the workmen utilizes metallic rod; Through stay bolt heat exchanging tube and return bend are delivered to the predetermined degree of depth, utilize the metallic rod construction to damage pipeline easily, difficulty of construction is big; Before the backfill, bad after pipe is accomplished down if the PE heat exchanging tube is fixed, under floating function; Be easy to come-up, reduce the heat exchange effect, therefore; Generally all backfills in time after down pipe is accomplished, thus cause the leak detection work of suppressing behind the pipe down generally to do relatively more carelessly, just in case fortuitous event such as heat exchanging tube destruction has taken place in following pipe process; Can only hot well entirely be scrapped, cause very big loss.
" a kind of U type elbow of earth source heat pump " that patent 201020121183.X provides solved this problem preferably, still, this device since counterweight below; Take the degree of depth of source well partially, needed many drilling wells, increased cost; Especially in formation area, the drilling cost of source, the ground well that counter weight device is shared is equivalent to tens and even up to a hundred the costs that the U type is curved; Thereby increased cost, limited use to a certain extent.
Summary of the invention
The pipe arrangement purpose is to overcome the deficiency of existing technology under the ground buried pipe of ground source heat pump, provide a kind of simple in structure, construction is time saving and energy saving, pipe arrangement under the ground buried pipe of ground source heat pump that can guarantee construction quality.
To achieve these goals, the technological scheme of employing is following:
The U-shaped of ground buried pipe of ground source heat pump is curved, generally is that the PE material is processed, and directly is connected with the PE heat exchanging pipe above, and the ground heat exchanger of single U cloth form of tubes is two PE heat exchanging tubes, and the double-H groove weld heat exchanger has 4 PE heat exchanging tubes.In the time of following pipe,, be positioned over the curved top of U type with pipe arrangement under the prefabricated ground buried pipe of ground source heat pump; The interim centres that perhaps are permanently secured to 2 or 4 ground pipe laying PE heat exchanging tubes; Because the deadweight of pipe arrangement is bigger under the ground buried pipe of ground source heat pump, can overcome the curved suffered buoyancy of PE heat exchanging tube and U-shaped, thereby under the self gravitation effect; Arrival point source bottom is accomplished plumber's preface down smoothly.Work progress is easy to operate, and is time saving and energy saving.
After following pipe is accomplished; Do not need timely backfill; The leak detection work of suppressing after time enough descends pipe is arranged; Instant just in case in pipe process down because borehole wall stone scratches fortuitous event such as heat exchanging tube takes place, only need heat exchanging tube and following pipe arrangement be extracted replacing to get final product, backfill can not take place and situation that can't tube drawing.
Pipe arrangement can use made under the ground buried pipe of ground source heat pump, also can use concrete prefabricatedly, can also be to fill out sandstone or other weights in the middle of the metal shell, so long as density can be used greater than the material of slime water density in the well.The edges and corners of pipe arrangement are generally all made circular-arcly under the ground buried pipe of ground source heat pump, avoid sharp corner angle to scratch the PE pipe as far as possible and bend with U-shaped.According to the different geological condition, can use pipe arrangement under the ground buried pipe of ground source heat pump of different sizes and weight.
U the type curved bottom and the outside can be given prominence in the lower end of pipe arrangement under the ground buried pipe of ground source heat pump, so that protect the U type curved better, in following pipe process and after pipe puts in place down, are unlikely to the curved scratching equivalent damage that receives of U type.
The curved bottom of outstanding U type, lower end of pipe arrangement all belongs to this patent protection domain under bottom that the outstanding U type in the lower end of pipe arrangement is bent under the ground buried pipe of ground source heat pump or the ground buried pipe of ground source heat pump;
The curved outside of outstanding U type, the outside of pipe arrangement all belongs to this patent protection domain under the outside that the outstanding U type in the outside of pipe arrangement is bent under the ground buried pipe of ground source heat pump or the ground buried pipe of ground source heat pump.
