Description
Technical field
The utility model belongs to air conditioner energy saving and field of renewable energy resource utilization, especially relates to a kind of perpendicular buried ground heat exchanger technology of soil buried tube type.
Background of invention
Earth surface water source and soil are huge solar thermal collectors, have collected 47% solar energy, utilize human every year more than 500 times of energy.Earth-source hot-pump system is that a kind of underground shallow-layer ground that utilizes can, but comprise underground water, the not only heat supply of earth or surface water etc. but also the high-effective building energy-saving air-conditioning system that can freeze, by importing a spot of high-grade electric energy, can realize of the transfer of low temperature potential energy to the high temperature potential energy, wherein, water resource heat pump is to have utilized earth surface or shallow-layer water source as Cooling and Heat Source, carries out the heating air-conditioner system of power conversion, deservedly becomes a kind of form of regenerative resource.Water source heat pump technology utilizes in the middle of the process of underground water and earth surface water source, because of the cost problem that has groundwater recharge and surface water is influenced by environmental temperature and heat exchange to the problems such as influence of water ecological setting, make its application be subjected to certain restriction.
Soil buried tube type heat pump is another mode of earth-source hot-pump system, realizes the heat exchange of heat-carrying agent and rock earth by burying the soil heat exchange device underground, and as in the heat supplying process in the winter time, heat-carrying agent takes heat to indoor by system from underground collection heat again; System's antikinesis when freeze summer promptly from the indoor heat of taking away, is delivered to heat in the underground ground by system again.Therefore, last earth buried tube type heat pump has kept groundwater heat pump to utilize the advantage of the earth as Cooling and Heat Source, do not need simultaneously groundwater abstraction as the medium that conducts heat again, it is a kind of sustainable development building energy conservation new technology with great development future, underground pipe formula circulating geothermal heat exchanger can be used as a front end coupling unit of soil buried tube type heat pump, usually, be divided into by burying ground heat exchanger pipe laying mode: horizontal coiled pipe, perpendicularly buried pipe and spiral coil, this earth-source hot-pump system to the requirement of the material of soil heat exchange device and geologic structure than higher, wherein, the horizontal coiled pipe floor space is bigger, need excavation, therefore pipe laying depth is shallow, is subjected to face of land temperature, factor affecting such as solar radiation are bigger, and the stability of a system is low; Perpendicularly buried pipe is subjected to ground surface environment temperature effect little, but pipe laying is dark, hole drill pick expense and associated materials expense increased accordingly when employing was vertically mounted on high pressure-bearing vinyon perpendicularly buried pipe among vertical shaft or the sleeve pipe with the U-shaped tubulose, the spiral coil floor space is little, invest less relatively, but need excavation, the heat exchange effect is between between the above two, not as perpendicularly buried pipe, because the investment of soil buried tube type heat pump wants high than other earth source heat pump mode, so this system generally is only applicable to the smaller inhabitation class single building of area, in heavy construction, use difficulty relatively.
Summary of the invention
The purpose of this utility model is to provide a kind of perpendicular buried ground heat exchanger that is used for air conditioner energy saving, make it faster, simpler and easy than existing U type pipe perpendicularly buried pipe technology construction, requirement to material and construction geology structure decreases, operating expenses will reduce than prior art with cost, use accommodation and function ratio prior art to enlarge, simultaneously, circulating geothermal heat exchanger can not tie up too much land area.
The utility model is achieved through the following technical solutions, adopt a kind of perpendicular buried ground heat exchanger, form underground heat heat exchange closed circuit by underground pipe, heat exchange unit, circulating pump, heat-carrying agent, circulation line etc., it is characterized in that, described underground pipe be in the outer tube fixing have interior pipe bury ground backflow sleeve pipe, the heat-carrying agent that is made for thermal source or low-temperature receiver in the underground heat heat exchange closed circuit through the interior pipe of underground pipe or inner and outer pipes interlayer flow into from ground bury ground backflow sleeve bottom after, be back to ground through inner and outer pipes interlayer or interior pipe again and form underground reflux cycle.The fixing of interior pipe in outer tube of described underground pipe is through holding frame or through the fixing of the clamping circular ring plate of band liquid opening etc.Described underground pipe can adopt through the antiseptic metal tube of metallochemistry plating or surface metal plastic-coated and make.Described heat-carrying agent comprises and contains solid-state phase changes energy storage material fluid liquid in liquid and the liquid.But the liquid water of described heat-carrying agent or mineral solution or emulsion.Described underground pipe is single or many, but the latter's layout line style or matrix type etc., and its best adjacent spaces is 4 to 6 meters.Described underground pipe outer wall bores in the ground hole can be provided with the filler of preserving moisture that absorbs water, and between underground pipe the soakaway trench of preserving moisture can be set.Can have heating water tank and energy-accumulating water tank in the described underground heat heat exchange closed circuit.The heat-carrying agent that is made for thermal source or low-temperature receiver in the described underground heat heat exchange closed circuit can be used as the thermal source of level eventually or low-temperature receiver or as secondary thermal source or low-temperature receiver.
The utility model has the advantages that: since adopt underground pipe be in the outer tube fixing have interior pipe bury the backflow sleeve pipe, make it to be adapted to pass through the less single tube of diameter and vertically creep into or ram the rapid construction that modes such as pressing pipe laying is buried the ground heat exchanger, thereby, can exempt and excavate pipe laying, construction volume reduces, and compare with corresponding U type pipe perpendicularly buried pipe prior art, the pipe laying construction all has bigger reduction to the material of soil heat exchange device and the requirement of construction geology structure, the also corresponding reduction of operating expenses and associated materials expense, and the engineering accommodation of circulating geothermal heat exchanger obtains enlarging.In addition, can be arranged on the auxiliary pile that the surface structures area is interior or double as is built when putting but adopt underground pipe to erect, thereby can reduce the building pile foundation cost, the big-and-middle-sized circulating geothermal heat exchanger of exempting considerable part simultaneously was because of tying up the application restriction of multiple footprint.
