Abstract
A reinforced concrete well making use of geothermal energy is characterized in that an enclosed well is built inside a manually or mechanically excavated well with the depth of 5 to 300m by reinforced concrete pouring; a fluid inlet pipe and a fluid outlet pipe are inserted in the well, and the pipe with better thermal insulation is inserted in the lower end of the well; and the diameter of the well, the thickness of the well wall and the reinforced structure are enlarged along with the enlarged pressure and height of buildings on the ground. Heat exchange is conducted between a cold/hot medium fluid circulating in the well and underground soil and rocks through the well wall. For systematic application, multiple concrete wells are generally connected in series and then in parallel to form a network. The utility model can save energy and electricity, and facilitate the popularization of geothermal energy central air-conditioning systems in common residence communities. The cold/hot exchange medium water poured in the well can achieve no leakage when pressurized to 0.02MPa and above.
Description
Technical field
The utility model relates to a kind of reinforced concrete well that utilizes the ground energy.
Technical background
Can make the air-conditioning of heat exchange at present, the mode that adopts pipe laying mostly or dig a well and draw water and recharge with utilizing.The pipe laying mode, because low, the complex process of heat exchange efficiency does not reach Air-conditioner design standard and actual instructions for use, very difficult large tracts of land is promoted the use of; Draw water and recharge, owing to be rich in the hard water of mineral matters such as calcium, magnesium, easily fouling in heat exchanger of air condition descends air-conditioner efficiency.And this mode can only be used for the earth source heat pump central air conditioner system of conventional junction configuration, and traditional structure earth source heat pump central air conditioner system operation control is complicated, essential outfit personal management, maintenance, repair.Be used for residential quarters, share the expenses and operating cost are all higher, and inconvenience is promoted.
Summary of the invention
The purpose of this utility model is that a kind of utilization ground energy resource will be provided, and can be used as the sealing reinforced concrete well of solid soil and accessory building pile foundation.
The technical solution of the utility model is: artificial or machinery excavates 5 a usefulness---in the dark well of 300M, with sealing well of armored concrete cast, have in two pipeline fill-in wells of fluid, wherein one is well-insulated pipeline down, the lower end of fill-in well, other has a top of going up pipeline at well.The diameter of well, thickness of shaft wall and bar construction strengthen according to the increasing of aboveground building pressure and height.
Be circulated in the cold and hot media fluid in the well, carry out heat exchange by the borehole wall and underground rock.System applies, generally by after the series connection of a plurality of concrete wells again and be unified into net.Adopt the utility model, energy saving is convenient to ground energy central air-conditioning in general residential quarters penetration and promotion.The cold and hot medium of exchange water of perfusion in the well, it is above non-leakage to be forced into 0.02MPa.
Description of drawings
Accompanying drawing is the utility model organigram.
Among the figure 1, the sealing well, 2, the borehole wall, 3, go up pipeline, 4, pipeline down, 5, water-guiding hole.
The specific embodiment
Introduce the utility model below in conjunction with accompanying drawing.
With reference to accompanying drawing, one 10 of mine working---30M is dark, and the well of diameter 1.2---2M is poured into a mould the sealing well 1 of a reinforced concrete structure then.In the sealing well, top has one to go up pipeline 3, and following pipeline 4 is from top to down near the shaft bottom, and there is water-guiding hole 5 lower end.Be convenient to convection current for making entery and delivery port keep the bigger temperature difference, following pipeline 4 adopts effect of heat insulation plastic pipe preferably.The upper and lower pipeline of sealing in the well can be used separately as and be inlet tube and outlet tube, promptly is circulated in the cold and hot media fluid in the well, can advance by above pipeline, and following pipeline goes out; Also can advance by following pipeline, last pipeline goes out.
Claims (2)
1, a kind of utilize ground can reinforced concrete well, it is characterized in that: artificial or machinery excavates 5 a usefulness---in the dark well of 300M,, have in two pipeline fill-in wells of fluid with sealing well of armored concrete cast.
2, by the described reinforced concrete well of claim 1, it is characterized in that: go up the top that pipeline (3) places well; With the following pipeline (4) of well-insulated materials processing, from top to down near the shaft bottom.
