Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As described in Figure 1, the geothermal air conditioning system that the present embodiment provides, comprise the first high-order bucket 10 connected successively, enter well casing 20, heat exchange pipeline 30, go out well casing 40 and the second high-order bucket 50, also comprise underground conservation pool 60, water circulating pump 70 and circulation pipe 80, first high-order bucket 10 and the second high-order bucket 50 preferably seal bucket, the liquid in bucket is prevented to be dissipated in atmosphere, and underground conservation pool 60 can be open, also can be enclosed, in the present embodiment, underground conservation pool 60 is open Jing Chi, water in pond is well water, water in such underground conservation pool 60 also can be used as industry or domestic water.
Heat exchange pipeline 30 is positioned at underground conservation pool 60, for carrying out exchange heat with the water in underground conservation pool 60.Heat exchange pipeline 30 is preferably metal heat-conducting pipeline, preferably high the and metal heat-conducting pipeline that heat transfer coefficient is high of corrosion resistance, and the particular type of heat exchange pipeline 30 can be chosen from existing metal heat-conducting pipeline, no longer describes in detail herein.In addition, heat exchange pipeline 30 in continuous print S shape or in the shape of a spiral around, heat exchange pipeline 30 and the contact area of the water in underground conservation pool 60 can be increased like this, be convenient to the exchange of heat.
Underground conservation pool 60 is positioned at the position on less than six meters, ground, concrete position needs the geology according to underground conservation pool 60 place, the actual environment of weather and locality is determined, certainly, underground conservation pool 60 needs the place being positioned at underground water source abundance, to realize exchange heat by underground water source.It should be noted that, the degree of depth of underground conservation pool 60 is preferably identical with the degree of depth of the living-use water well of routine, if underground conservation pool 60 is too shallow, then the water temperature in pond along with seasonal variations larger, be difficult to reach effect cool in summer and warm in winter, affect refrigeration or the heating effect of geothermal air conditioning system; If underground conservation pool 60 is too dark, then cost of digging a well is too high, does not also have obvious lifting, because when cistern 60 reaches the degree of depth of living-use water well, the water temperature in pond has trended towards constant to refrigeration or heating effect.
First high-order bucket 10 and the second high-order bucket 50 are positioned in same level, and the first high-order bucket 10 and the second high-order bucket 50 are positioned at the top of other parts of geothermal air conditioning system, that is to say the below being all positioned at the high-order bucket 50 of the first high-order bucket 10 or the second into well casing 20 and the pipe shaft going out well casing 40.When reality uses, the first high-order bucket 10 and the second high-order bucket 50 can be arranged in roof, without the need to additionally arranging support to place the first high-order bucket 10 and the second high-order bucket 50.
Should toward the liquid of perfusion in the first high-order bucket 10 as heat-conducting medium before using, this liquid preferably has good thermal conductivity factor, and concrete liquid can for select according to actual needs, if use water is as heat-conducting medium etc.Liquid is poured in after in the first high-order bucket 10, can successively along entering well casing 20, heat exchange pipeline 30 and go out well casing 40 to flow in the second high-order bucket 50 under the effect of hydraulic pressure, when in the second high-order bucket 50, also there is a certain amount of liquid, and liquid level in the first high-order bucket 10 concordant with the liquid level in the second high-order bucket 50 after, stop toward perfusion fluid in the first high-order bucket 10.
Water circulating pump 70 is positioned at the second high-order bucket 50, and is immersed in the liquid of the second high-order bucket 50, and one end of circulation pipe 80 is connected with the outlet of water circulating pump 70, and the other end is positioned at the first high-order bucket 10.When water circulating pump 70 is by after in the Liquid extracting in the second high-order bucket 50 to the first high-order bucket 10, under the effect of pressure differential, liquid in first high-order bucket 10 successively along entering well casing 20, heat exchange pipeline 30 and go out well casing 40 to flow in the second high-order bucket 50, can form flow circuit.
Go out on well casing 40 and be provided with indoor heat exchanger 90, the indoor set that indoor heat exchanger 90 can use for conventional air-conditioning, its concrete structure no longer describes in detail herein.Indoor heat exchanger 90 can only have one or two, also can have multiple, and when indoor heat exchanger 90 has multiple, multiple indoor heat exchanger 90 can be connected on out on well casing 40, also can be connected in parallel on out on well casing 40.The advantage of the mutual series connection of multiple indoor heat exchanger 90 well casing 40 needs one, and overpressure is relatively stable, and shortcoming is that the initial refrigeration of the indoor heat exchanger 90 of close second high-order bucket 50 one end or heating effect are relatively poor; Multiple indoor heat exchanger 90 advantage parallel with one another is that the refrigeration of each indoor heat exchanger 90 or heating effect are more or less the same, shortcoming well casing 40 to need many arms, the arm going out well casing 40 has sudden change with the fluid pressure of supervisor's intersection, make to draw the pressure transient in well casing 40, impact refrigeration or heating effect.In the present embodiment, indoor heat exchanger 90 has multiple, multiple indoor heat exchanger 90 is connected on out on well casing 40 mutually, although this connected mode part indoor heat exchanger 90 initially freezes or heating effect is relatively poor, the fluid temperature gone out after long-play in well casing 40 can trend towards unanimously.
Preferably, in the present embodiment, the caliber entering well casing 20 is greater than the caliber of well casing 40, and like this, under hydraulic action, the flow rate of liquid gone out in well casing 40 can be greater than into the flow rate of liquid in well casing 20, sustainablely provides cold air or heating installation for indoor heat exchanger 90.In addition, entering well casing 20 and going out well casing 40 is all thermal insulation pipe, can effectively prevent heat to scatter and disappear in the duct.
Above by reference to the accompanying drawings to invention has been detailed description; but embodiments of the present invention are not limited in above-mentioned embodiment; those skilled in the art can make various distortion to the present invention according to prior art; as the liquid in pipeline in above-described embodiment is changed to gas; and adopting the water circulating pump 70 etc. in the upper embodiment of aspiration pump replacement, these all belong to protection scope of the present invention.
