Description
Technical field
This utility model relates to the component of earth-source hot-pump system used by a kind of building energy conservation, especially a kind of earth-source hot-pump system underground pipe unit.
Background technology
At present, in building energy saving field, the buried recirculated water U-tube road of Ground-source Heat Pump and soil heat-shift, using soil as regenerative resource, there are circulating hot water or the cold water of a fixed difference difference for building offer and atmospheric environment continuously, reach the purpose of building energy conservation.Within more than 20 years, do not corrode because using behind expected design U-shaped underground pipe embedment underground, therefore have employed relatively inexpensive PVC (engineering plastics) and manufacture linear type pipeline, front end U-tube connects, horizontally or vertically insert soil, and it is responsible for serial or parallel connection with water-in and water-out, form underground pipe circuit units.But, at present conventional linear type PVC underground pipe have the disadvantages that (1) as the heat transfer medium between recirculated water and soil, the heat-transfer capability of PVC material is relatively low, i.e. heat exchanger effectiveness is on the low side；(2) resistance to compression, bending strength are relatively low, when soil occurs to wriggle, may hold and can't stand that horizontal shear occurs disrumpent feelings；(3) U-tube road perpendicular buried depth degree in soil is limited, or horizontal to bury occupation of land limited, and unit pipeline path is short, makes the recirculated water operation time in underground shorter, it is impossible to heat-shift abundant with soil；(4) underground pipe is less than normal with the heat exchange area of soil.A kind of can be effectively improved intensity accordingly, it would be desirable to design, increase heat transfer area, extend recirculated water at the underground pipe of underground circulation time.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of earth-source hot-pump system underground pipe unit, can be effectively improved intensity, increase heat transfer area, extend the recirculated water circulation time in underground.Meanwhile, simple structure, easily manufactured, with low cost, it is beneficial to promote.
The technical solution of the utility model is:
A kind of earth-source hot-pump system underground pipe unit, including body, described body is two serpentine pipes be arrangeding in parallel, and its one end is connected by U-tube, and the other end is connected respectively to water inlet pipe and outlet pipe.
Further, described serpentine pipe PVC pipe is made, and its helix central diameter and pitch determine all in accordance with caliber.
Further, the centrage of the junction of described serpentine pipe and inlet tube and outlet tube deviates on the central diameter circumference of serpentine pipe, and with the centrage of inlet tube and outlet tube in the same plane.
Further, described two corrugated tubings are connected with water inlet pipe and outlet pipe with cross-line pipe by transition conduit respectively.
The beneficial effects of the utility model:
This utility model is reasonable in design, simple in construction, can be effectively improved intensity, increases heat transfer area, extends the recirculated water circulation time in underground, raising heat exchanging efficiency, and increases the service life.Meanwhile, easily manufactured, with low cost, it is simple to promote.

Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4.
A kind of earth-source hot-pump system underground pipe unit, including body.Described body is two serpentine pipes be arrangeding in parallel 5.These two serpentine pipes are positioned at one end in the same direction and are connected to the two ends of a U-tube 6 respectively by pipe joint, so that these two serpentine pipes 5 are connected.Meanwhile, the other end of these two serpentine pipes 5 is connected to transition conduit 3 or cross-line pipe 7 by pipe joint 4 respectively, then is connected to water inlet pipe 2 and outlet pipe 1 by big tubule three way cock 8, makes installation and keeps in repair convenient, and constituting a water stream channel unit in parallel.When needs change series unit into, it is only necessary to by water inlet pipe 2 and serpentine pipe 5 one end directly, outlet pipe 1 with serpentine pipe 5 other end directly.Described serpentine pipe 5 uses PVC material manufacture, has excellent decay resistance, and cheap.The helical structure of described serpentine pipe 5, compares original linear type pipeline and possesses advantages below: the ability of (1) opposing soil creep horizontal force is greatly enhanced；(2) increase route of pipe line electrical path length, therefore add the recirculated water operation time in soil, make the heat exchange between recirculated water and soil the most abundant；(3) add the contact area of pipeline and soil, improve recirculated water and the heat exchange effect of soil in element loop.The spiral central diameter φ E of described serpentine pipe 5 need to determine according to caliber φ N, and cannot be less than the min. turning radius that its hot bending process limits.Meanwhile, the multiple that pitch m is caliber φ N of described serpentine pipe 5, should not be the closeest, in order to avoid affecting heat-transfer effect.Length L of described serpentine pipe 5 can design according to the underground thermal property of engineering investigation and engineering special project and determine.The space D of described each serpentine pipe 5 should be greater than the twice of spiral central diameter φ E.Described serpentine pipe 5 deviates on the middle line of serpentine pipe 5 with the centrage of the junction of inlet tube and outlet tube, and with the centrage of inlet tube and outlet tube in the same plane, it is simple to install and keep in repair.Meanwhile, also can make serpentine pipe 5 relatively underground, contact well with soil, make heat exchange more abundant.
This utility model is not directed to part and the most same as the prior art prior art maybe can be used to be realized.
