Abstract
The utility model relates to a solar energy seasonal underground heat storage device, which consists of a barrel-shaped parent well, a plurality of sub wells connected with the parent well, and a solar energy gather device, wherein the well wall of the parent well is provided with well mouths of the sub wells and is connected with the sub wells; a closed end of each sub well extends underground and is characterized in that the sub well comprises a water delivery pipe leading to the closed end of the sub well; and the sub wells, the water delivery pipes in the sub wells, a water delivery main line, a circulating pump, a load heat exchanger and the solar energy gather device constitute a waterway loop of the solar energy seasonal underground heat storage device. The utility model has the beneficial effects that the device is convenient to construct, reform and disassemble, can be arranged and constructed under the existing building and is environment-friendly, and the well pipes of the sub wells are not easily damaged and have high reliability; and the heat exchange heat resistance of the waterway loop comprising the sub wells, the water delivery pipes in the sub wells, the water delivery main line, the circulating pump, the load heat exchanger and the solar energy gather device is low. An embodiment is provided according to an attached drawing.
Description
Technical field
The utility model relates to solar cross-season underground heat storage device.
Background technology
Existing a kind of soil storage in season solar thermal energy system of striding is by excavating soil, the geotextiles cistern is set in soil, backplate and earthing formation being set on cistern.Its cost is higher.
Summary of the invention
The purpose of this utility model is that solar cross-season underground heat storage device will be provided.
The technical scheme in the invention for solving the technical problem:, form a solar cross-season underground heat storage device with the female well of a tubular, several sub-well and solar energy heat collectors that are connected with female well.A plurality of sub-well well heads are set on female well borehole wall and connect a plurality of sub-wells.Sub-well is the blind pipe structure, and its blind end stretches into underground.Sub-well places soil.Sub-well contains the water-supply-pipe that leads to its blind end; Water-supply-pipe in Zi Jing, the sub-well, water delivery arterial highway, circulating pump, load heat-exchanger rig and solar energy heat collector are formed the loop, water route of a solar cross-season underground heat storage device.
The beneficial effects of the utility model: build, transform and remove convenient, can construction be set in the soil under the existing building, sub-well well casing is not easy to damage reliability height, environmentally friendly.The loop, solar cross-season underground heat storage device water route that water-supply-pipe in Zi Jing, the sub-well, water delivery arterial highway, circulating pump, load heat-exchanger rig and solar energy heat collector are formed, the heat exchange thermal resistance is low, and its operating expenses has only 40% of solar cross-season heat-storage facility that excavation builds.As long as extend sub-well length or increase the soil scope that sub-well number just can enlarge accumulation of heat.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of a solar cross-season underground heat storage device.
1. soil among the figure; 2. female well; 3. sub-well; 4. blind end; 5. water-supply-pipe; 6. water delivery arterial highway; 7. circulating pump; 8. heat-exchanger rig; 9. heat collector; 10. loop, water route; 11. openend; 12. valve sets.
The specific embodiment
Fig. 1 provides an embodiment of the present utility model.
Among Fig. 1, a plurality of sub-well 3 well heads of son are set and connect a plurality of sub-wells 3 on female well 2 boreholes wall of the tubular that places soil 1, sub-well 3 blind ends 4 stretch into underground.Sub-well 3 contains the water-supply-pipe 5 that leads to its blind end 4.Water-supply-pipe 5 in sub-well 3, the sub-well 3, the water delivery arterial highway 6 that is communicated with each water-supply-pipe 5, circulating pump 7, load heat-exchanger rig 8 and solar energy heat collector 9 are formed the loop, water route 10 of a solar cross-season underground heat storage device.The water that enters water-supply-pipe 5 flows out at water-supply-pipe 5 openends 11 places, and returns female well 2 from the interlayer between sub-well 3 inside and the water-supply-pipe 5, by sub-well 3 boreholes wall and soil 1 heat exchange, makes the temperature change of soil 1 in returning the way.By switch valve group 12, make solar energy heat collector 9 connect loop, water route 10,8 shutoffs of load heat-exchanger rig, solar thermal energy enters soil 1 heats up soil 1.By switch valve group 12, make solar energy heat collector 9 shutoffs, load heat-exchanger rig 8 connect loops, water route 10, the heat energy that stores in the soil 1 is by loop, water route 10 offered load and make soil 1 cooling.
