Abstract
The invention discloses an efficiency enhancing device of an underground heat exchanger. The efficiency enhancing device is provided with a main water supply pipeline, branch pipelines are connected to the main water supply pipeline, valves are arranged between the branch pipelines and the main water supply pipeline, branch pipes are symmetrically arranged on the branch pipelines, seepage pipes are arranged on the branch pipes at equal intervals, and at least three sets of seepage holes are arranged on the pipe walls of the seepage pipes. Each set of seepage holes comprise at least three seepage holes and are arranged in a regular triangle on the same plane. The distance between the adjacent two sets of seepage holes is 5-10 cm. The efficiency enhancing device of the underground heat exchanger can keep the wettability of an underground pipe laying system of a ground source heat pump to enhance the heat exchanging efficiency of underground soil, keep the wettability of the soil and prevent the soil from encrusting and separating to form cavities between the pipe walls and the soil. Meanwhile, the invention has the advantages of low cost, low requirement for the materials of pipes, simple installation procedure which can be carried out when underground pipelines are constructed, high installation efficiency and good using effect.
Description
Technical field
The present invention relates to a kind of enhancing device, relate in particular to a kind of efficiency enhancing device of underground heat exchanger.
Background technology
There are some researches show: the underground temperature below 5 meters does not change with external environment and changes of seasons substantially, approximate local average temperature of the whole year, soil has accumulation of energy characteristic preferably, temperature and has many advantages such as delay and decay property with respect to outside air temperature, so soil is a kind of desirable thermal source.
Earth source heat pump is with the thermal source of soil as source pump, earth source heat pump with the earth surface thin solum as thermal source, the heat that often discharges or absorb with needing in the condenser of traditional air-conditioning or the evaporimeter by intermediate medium as carrier, and intermediate medium is circulated by the earth in closed loop, thereby the purpose that realization and the earth carry out cold and hot exchange.
At north cold area, the fluid temperature that enters underground heat exchanger winter is general all below 0 ℃, and the soil of water capacity may freeze around the heat exchanger.According to qualitative analysis, when moisture content freezes, there is a large amount of latent heat to be released, therefore under the heat situation that absorbs equivalent amount, the temperature amplitude that soil reduces is little, and moisture content is many more, the latent heat that discharges is many more, and it is more little that temperature reduces amplitude, and is high more at the soil moisture of contiguous heat exchanger pipe laying.When subterranean pipe line is embedded in comparatively dry following time of soil, separations of crusting easily of underground clay, tube wall and soil formation cavity are unfavorable for heat transfer.
Summary of the invention
Purpose of the present invention is exactly the defective that exists at prior art, and a kind of efficiency enhancing device of underground heat exchanger is provided, and this device can provide moisture for the earth source heat pump underground penstock system, strengthens heat exchange.
Technical scheme of the present invention realizes with following method:
A kind of efficiency enhancing device of underground heat exchanger, wherein, be provided with a main water supply pipe, be connected with lateral on the main water supply pipe, be provided with valve between lateral and the main water supply pipe, manage in the tributary that is provided with of symmetry on the lateral, equidistantly is provided with the seepage flow pipe on the pipe of tributary, and the tube wall of seepage flow pipe is provided with the seepage flow hole.
The caliber of the caliber of described main water supply pipe and seepage flow pipe all is at least 20mm.
The aperture in described seepage flow hole is 6-10mm.
Described seepage flow hole is at least three groups.
Described every group of seepage flow hole is at least three, and on same horizontal plane, takes equilateral triangle to arrange.
Distance between the described two adjacent groups seepage flow hole is 5-10cm.
The good effect of technical scheme of the present invention is:
This efficiency enhancing device of underground heat exchanger can keep the wettability of earth source heat pump underground penstock system, and the underground heat exchange efficiency is improved, and keeps the wettability of soil, prevents the soil crust separation, forms cavity between tube wall and the soil.Simultaneously, the present invention is with low cost, and the material of tubing is less demanding, and installation procedure is simple, can in the subterranean pipe line construction, carry out simultaneously, and the installation effectiveness height, result of use is good.
