Technical field

The invention relates to the underground heat energy of utilization, as the device that utilizes at aspects such as cooling heating, water supply, warm water swimming pool, plant culture, the animal feeding that contains fish or snow melts in underground unlimited existence.

Background technology

What in the past, underground water (warm water) was considered is the technology of for example utilizing at aspects such as cooling heating, water supply, warm water swimming pool, plant culture, the animal feeding that contains fish or snow melts.This technology is to utilize at the underground underground water that exists, so operating cost is cheaper, and the advantage that can not produce environmental problems such as atmosphere pollution is arranged simultaneously.

Summary of the invention

Technology in the past is because need a large amount of underground water, so the problem that ground sink of bringing out is arranged.For example use occasion, have the spray that produces because must sprinkle water to splash, again because the problems such as traffic accident of freezing to be easy to cause motor vehicle of water at pavement snow melting.

Propose because The present invention be directed to the problems referred to above, ground can not sink, the occasion of just in snow melt, utilizing, with provide the spray that can not produce to splash and the problems such as traffic accident of motor vehicle as research topic.

The specific embodiment

Relevant the present invention utilizes the example of geothermal device, as shown in Figures 1 to 4.This device is to be equipped with heat exchanger 1, heat release pipe 2 and heat pump 3, also is equipped with simultaneously the heat storage tank 8 of remaining thermal energy storage from case of necessity on.

Heat exchanger 1 is vertical buried place to underground 100m～200m, gathers underground heat energy by first heat medium in inner loop.The structure of this heat exchanger 1 is not defined, and for example can use concentric double cast and U word cast.

Concentric double cast is as shown in Figure 2, in the urceolus 1a of bottom part sealing, insert inner core 1b with concentric shape, first heat medium begins to send into from the upper part of inner core 1b, and enter among the gap path 1c that forms between urceolus 1a and the inner core 1b in the counter-rotating of the end portion of inner core 1b, and gather underground heat energy along with the rising of heat medium, the direction of last part is from its upper end discharged.

U word cast is as shown in Figure 3, at the core of tube body 1d dividing wall 1e is set and forms two path 1f, and first heat medium is supplied with since the path 1f of a side, rises in this end portion counter-rotating, and the opposite side path 1f of part discharges from its upper end.

Heat release pipe 2 is that tubulose is the formation of hair clip sigmoid, in inner loop second heat medium is arranged, and discharges this heat energy.

Heat pump 3 is to be connected by first peripheral passage 4 with circulating pump 7 with heat exchanger 1, having above-mentioned heat release pipe 2 simultaneously is connected by second peripheral passage 5 with identical circulating pump 7, having inner loop has the 3rd peripheral passage 6 of the 3rd heat medium, the heat energy of first heat medium that absorbs, this heat energy heat up second heat medium.

In this example, heat release pipe 2 mainly is to use as room heating cooling machine.Promptly this heat release pipe 2 is that the heating installation jar 9 at storage heating installation, cold air jar 10, radiant heater 11, fan heater 12 or the beverage of storage cold air utilize with aspects such as coolers.

The relevant geothermal device that utilizes at this example is following the running.At first being arranged on the circulating pump 7 of first peripheral passage 4 and second peripheral passage 5, each is self-driven, drives heat pump 3 simultaneously.Like this, first heat medium that circulates in the heat exchanger 1 is gathered underground heat energy, delivers to heat pump 3 by first peripheral passage 4.

Absorb the heat energy of first heat medium in these heat pump 3, the three heat medium, the work of expanding or compressing heats up by making second heat medium like this.Second heat medium after the intensification arrives heat release pipe 2 by second peripheral passage 5, and discharges heat energy at this.By carrying out this process repeatedly, thus the release heat energy of continuous effective.

Other example of the present invention, as shown in Figure 5.In this example, heat release pipe 2 mainly uses as water heater.Promptly this heat release pipe 2 is to utilize in the water tank 14 at stored hot water, multi-form bathing pool 15 or the warm water swimming pool 16.Also have heat pump 3 that the function of refrigerator is arranged, can in air-conditioning system, be used.

Promptly heat release pipe 2 uses occasion at the snow melt machine in the present invention, with plural form be embedded in the road surface under, the release heat energy that makes it to continue utilizes this heat energy to come accumulated snow on the melting road surface.

The relevant device that utilizes underground heat in above-mentioned example did not draw phreatic way because use arbitrarily in the past, so can not cause sinking of ground.In addition in the occasion of utilizing aspect the road surface thawing accumulated snow, because needn't sprinkle water as before, so spray splashes and the problems such as traffic accident of motor vehicle just can not produce yet.Because utilization is present in underground abundant geothermal energy resources, can reduce operating cost again, can not produce environmental problems such as atmosphere pollution simultaneously.

Be that heat pump 3 and circulating pump 7 are except that source power supply, can also utilize device of solar generating and internal combustion engine TRT to turn round.Device of solar generating is as shown in Figure 6, utilize solar panel 17 to absorb sunshine, battery 20 in accumulator box 18 charges by control substrate 19 when needs charge, and by rectifier 21 electric power of necessity is offered heat pump 3 and circulating pump 7 again.

The effect of invention

The relevant geothermal device that utilizes of the present invention is because utilize underground heat energy, so can not draw Play sinking of ground. Also have the occasion of utilizing aspect the road surface thawing accumulated snow, can not produce spray Splash and the problems such as traffic accident of motor vehicle. Be present in underground abundant ground because utilize again Thermal resource can reduce operating cost, can not produce the environmental problems such as atmosphere pollution simultaneously.
