Abstract

The utility model relates to an underground energy collecting pile, which comprises a concrete tubular pile used for building foundations. The utility model is characterized in that a heat exchange water inlet pipe is arranged in the concrete tubular pile, the upper end of the concrete tubular pile is provided with a concrete core filling cover, and two through holes are reserved in the concrete core filling cover; the upper end of the heat exchange water inlet pipe passes through one through hole in the concrete core filling cover, the other through hole in the concrete core filling cover is penetrated with a heat exchange water return pipe and the heat exchange water return pipe extends into the concrete tubular pile. A closed-loop system pipeline in a ground source heat pump system can be installed by the utility model directly utilizing a concrete tubular pile generalized by building industry at present so as to avoid digging a plurality of deep holes which are of 20-100 meters in the ground to increase the efficiency of construction. The utility model has the advantages of convenient construction and installation, short construction period, low construction cost, etc.; the utility model can be used for closed-loop system pipelines in ground source heat pump systems.

Description

A kind of underground energy resource collecting pile

(1) technical field

The utility model relates to earth-source hot-pump system, refers to the underground heat collecting pile in this system especially.

(2) background technology

Underground heat is the energy that obtains from earth interior, and the earth is a huge energy storage vault, and it can absorb 47% solar energy.Can there be bigger fluctuation in the temperature of earth surface with changes of seasons, and winter, ambient temperature was very low, and summer, ambient temperature was very high.And the subsurface temperature between surface soil layer 1.5-2 rice is annual constant about 10 ℃.

According to the data of world environments protection general administration, geothermal energy resources are the most efficient at present, environmental protection, and a kind of reliable energy that takes up an area of the space is saved in low energy consumption simultaneously again.It studies show that the ground heat-exchange system reduces emission of harmful substances when can reduce energy consumption significantly,, compare the pollution of environment as carbon dioxide and sulfur dioxide, removed the trouble of stacking coal from coal-burning boiler, compare with oil burning boiler, avoided the investment on oil storage tank to take up an area of again.Save operating cost about 75% with traditional comparing with the power consumption air-conditioning.

Earth-source hot-pump system is exactly according to remaining on the principle of these true geothermal energy of zone of constant temperature of 10 ℃ from the underground degree of depth below about 10 meters in the soil of the earth throughout the year, and the geothermal source (also claim ground can or geothermal energy) of utilizing the earth surface shallow-layer is as thermal source (or low-temperature receiver).One cover system designed and that implement can be realized heat supply in winter, can freeze and provide the system of health living water use again summer.

As high temperature heat source, the heat in the ground energy " is got " to come out to transmit in the building of transferring to the need heating in the winter time by source pump; Summer as cold temperature source, by source pump the heat in the building " is got " to come out to transfer in the earth soil, thereby realizes heat supply in winter, summer refrigeration.Earth source heat pump is realized the transfer of low level heat energy to high-order thermal source by input a spot of high-grade energy (as electric energy).In the winter time, earth source heat pump absorbs the underground energy and is used for constructure heating; Summer, process antithesis, heat pump absorbs heat in the building and it return is underground, has so promptly rationally utilized the underground energy, has kept underground heat again.Ground source heat pump technology has made full use of geothermal energy resources, and with the outstanding advantage of its energy-saving and environmental protection and sustainable development, as novel " green air conditioner ", has become the preferred version of cooling/warming system.

Existing earth-source hot-pump system all is the closed loop heat pumping system generally, and it is most widely used.Closed-loop system is to utilize the heat exchanger fluid be embedded in the underground pipeline and ground heat transfer medium (earth rock, underground water) to carry out interchange of heat and the energy that obtains is sent in the heat pump unit.Can be divided into horizontal closed-loop system and vertical closed-loop system according to the closed-loop system pipeline again in underground mode difference.Wherein perpendicular system is extensively adopted by various places always, its main cause is to extract institute's calorific requirement on limited land area to greatest extent, because it is that heat-exchange tube vertically is embedded in the deep hole about underground 20-100 rice that the pipeline of this system is installed, therefore construct bothers very much, and efficiency of construction is low, cost is high, labor operation intensity is big.Also take bigger ground area simultaneously, also improved construction cost simultaneously.

(3) summary of the invention

In order to solve the technical problem that above-mentioned prior art exists, the utility model provides a kind of concrete tubular pile of building foundation that can directly utilize to construct, easy construction, duration weak point, construction cost underground energy resource collecting pile low, not land occupation area.

The technical scheme that adopts is:

A kind of underground energy resource collecting pile of the present utility model, comprise the concrete tubular pile that the building foundation is used, its characteristics are to be provided with in the described concrete tubular pile interchange of heat water inlet pipe, the upper end of concrete tubular pile is provided with concrete and fills out core cap, concrete is filled out to give on the core cap and is left two through holes, the upper end of interchange of heat water inlet pipe passes concrete and fills out a through hole on the core cap, and another through hole that concrete is filled out on the core cap is equipped with an interchange of heat return pipe, and this interchange of heat return pipe probes in the concrete tubular pile.

The concrete tubular pile that the utility model can directly utilize present builing industry to promote carries out the installation of the closed-loop system pipeline in the earth-source hot-pump system, thereby can avoid digging on the ground the deep hole of many 20-100 rice, has improved efficiency of construction greatly.The utlity model has construction install convenience, advantage such as the construction period is short and construction cost is low, can be widely used in the closed-loop system pipeline in the earth-source hot-pump system.
