Description

Ground temperature heating cooling collection hot-well device

Technical field

The utility model belongs to the device that utilizes heating of ground temperature heat energy or cooling, and heat is not ground temperature heating cooling collection hot-well device.

Background technology

Ground resource heat pump heating and cooling are accepted by society, and the near-earth shallow earth is a novel energy, i.e. the low temperature heat energy that the earth contained in 200 meters on the shallow top layer of the earth.Because darker stratum can not be subjected to the interference that atmospheric temperature changes, so can keep stationary temperature throughout the year, outside air temperature far above winter, also be lower than the outside air temperature in summer, and has bigger thermal capacity, therefore the efficient of groundwater heat pump system is than air source heat pump height, and and there is not problem such as frosting in the COP value generally between 3 and 4.5.In addition, to space heating, make the temperature in the earth reduce by the heat in the heat pump absorption the earth simultaneously winter, promptly stored cold, can use for summer; Be transferred to the earth to the heat of building by heat pump summer, to the building cooling, stores heat for using winter in the earth simultaneously.

But people are when extracting this part energy, and currently used three kinds of methods have unreasonable place, and these three kinds of methods are: 1, extract underground water, get recharge after the temperature underground; 2, beat the dark deep-well perpendicularly buried pipe of a hundreds of hundreds of rice and get temperature; 3, excavate ground, related area cubic metre of earth all excavated tiling pipe laying or the buried temperature of getting of coil pipe up to the desirable temperature degree of depth.

First kind is to extract underground water, and underground water belongs to a kind of geological resource, adopts groundwater heat pump in a large number, as does not have reliably and recharge, and will cause serious consequence.Surface subsidence, ground fissure, the ground that a large amount of exploitations of underground water cause geological problem such as cave in is day by day remarkable.In the actual at home use, do not solve, the situation of underground water direct face of land discharging might occur, and in case geologic Environment Problem In occurs because the blockage problem of recharging is basic, calamitous often and can't retrieval.Said method can make extraneous air contact with underground water, causes the underground water oxidation, and underground water oxidation meeting produces a series of hydrogeology problems, changes as geologic chemistry, and geology is biological to be changed.In addition, domestic underground water return path materials is not done strict preservative treatment substantially at present, and underground water is through after the system, and water quality also can be subjected to certain influence.Water resource is in short supply, a most valuable current resource, and any waste and pollution to water resource is admissible anything but.

Second kind is to make a call to 100 to get temperature to the dark deep-well perpendicularly buried pipe of hundreds of mouth hundreds of rice, and the ground Buried Ground Source Heat Pump is one of forward position research topic in the field of air conditioning.Ground pipe laying earth-source hot-pump system is owing to have advantages such as coefficient of performance height, good energy-conserving effect, system are simple.But the project occupation of land area is big, and investment is high, and underground installation goes wrong, and must dig a well again, resets the warm system of getting.

The third is that the common shallow-layer of horizontal coiled pipe is buried underground, and this mode development technique is less demanding, and it is big to lay area, and the excavation project amount is huge, and excavation cost and cubic metre of earth transhipment amount are huge, are not suitable for large tracts of land and promote.

The utility model content

The purpose of this utility model is to provide a kind of ground temperature heating cooling collection hot-well device, and the cooling area that not only heats is big, extracts the ground temperature temperature constant, and polluted source not, and environment protecting is good, and the construction earth volume is few, and cost is not high, can use for a long time, is convenient to safeguard.

The purpose of this utility model is achieved in that a kind of ground temperature heating cooling collection hot-well device, on the lower well barrel of pit shaft with the uniform laterally duct layer that is being provided with of pit shaft axis, laterally the duct layer constitutes by radial horizontal duct radially is set with wellbore centre, laterally in the duct thermal-collecting tube is being installed movingly, intermediate thermal insulating layer is being set in thermal-collecting tube vertically thermal-collecting tube is being divided into feed tube and drain pipe vertically, on the termination, outer end of thermal-collecting tube, the return passage that is communicated with feed tube and drain pipe is being set, the hot water fluid mouth of pipe of termination, thermal-collecting tube inner end is being connected hot water manifold trunk and cold water manifold trunk with the cold water feed liquor mouth of pipe respectively by pipe joint, and hot water manifold trunk and cold water manifold trunk are connected to by upright hot water guiding tube and cold water guiding tube in the import of the outlet of geographical heat pump high temperature pipe and cryotronl and form the loop.

The aqueous solution that injects a certain proportion of ethanol and water mixed liquid in the thermal-collecting tube of the present utility model or be mixed with ethylene glycol is cooling medium liquid, receive the heating net to the heat supply of heating terminal or receive central air-conditioning and be terminal air-conditioning cooling on the net from earth source heat pump heating pad pipe outlet, other external condition and existing earth source heat pump are general.According to different load heating load areas, what the thermal-arrest conduit branch course borehole wall in the cross through hole road layer was outer radially distributes all around.Along the uniform laterally duct layer that is being provided with of pit shaft axis, the hot cross surface of thermal-collecting tube layer that constitutes uniform multilayer is long-pending big, extracts the ground temperature temperature constant, and polluted source not, and environmental protection effect is good, and construction soil amount is few, and cost is not high, can use for a long time, is convenient to safeguard.
