A rainwater and geothermy using water and energy reduction system and its operational method

The present invention relates to a water and energy saving system using rainwater and geothermal and its operation method, and more specifically, by using rainwater as agricultural water or daily water, it is possible to significantly save water, as well as rainwater and It is to save energy by using geothermal cooling and heating energy, which greatly improves the quality and reliability of the system so that consumers can plant a good image.

As is well known, geothermal heat is a stable and permanent source of cooling and heating energy. geothermy].

Geothermal heat refers to solar radiation stored in all soils such as soil, groundwater and surface water, which accounts for about 47% of the total solar radiation reaching the earth.

Due to the nature of geothermal energy resources, no matter how much you use, there is no risk of being permanently depleted, and the earth, with its enormous amount of heat in itself, is a huge energy source that can supply a significant portion of the growing acceptance of energy worldwide. It is also a circle.

However, although the amount of thermal energy inherent in the earth is not so much used, the interest in utilization has begun to increase as the real value and unlimited potential of geothermal energy are recently recognized.

Thanks to the constant development of technologies necessary for the use of geothermal energy, geothermal energy is being accepted as a major factor in solving the increasing complex energy problem in the world.

In view of the above geothermal energy characteristics,

Distributed in the first underground.

Second, there is little change in resource status throughout the year.

Third, there is no big difference everywhere.

Fourth, existing technologies can be used from the earth's surface to several kilometers of ground level, depending on the purpose (temperature level).

Fifth, about 51% of the solar energy irradiated on Earth is absorbed and preserved in the ground or ocean, and then radiated into space. Thermal energy generated during nuclear fission in the center of the earth is radiated to the universe through the surface of the earth.

Sixth, there is only a temporary state change according to the use state, and it is restored to its original state.

In recent years, a number of patents have been filed and registered by using the excellent geothermal effect.

Referring to the operation and effect of the water and energy saving system using the rainwater and geothermal heat and the operation method of the present invention configured as described above are as follows.

First of all, the present invention is to use the rain water as agricultural water or living water to significantly save water, as well as to significantly save energy by utilizing cooling and heating energy using rain water and geothermal heat. This will be explained in more detail later.

The present invention first goes through the step of collecting water flowing down from the roof through the water collecting unit (50).

That is, as shown in Figures 3 and 4, when the rainwater sensor 51 detects the first rainwater, the collection step blocks the first conduit 55 with the rotating plate 54 to receive rainwater containing a large amount of foreign matter ( 52) It is to be discharged to the outside, which is because the first rainwater contains a large amount of foreign matter, so that the first pipe 55 is blocked by the rotating plate 54 so that rainwater does not flow into the catchment filter 60. .

After the rainwater sensor 51 detects rainwater for 5 to 10 minutes, when the foreign matter is less in the rainwater, the step of opening the first pipe 55 by rotating the rotating plate 54 using the motor 53. do.

That is, if the rainwater falls after 5 to 10 minutes, since the rainwater falls less since it contains less foreign matters from this time, the first pipe 55 is opened to allow the rainwater to flow into the water collecting filter 60 through this place.

Thereafter, the water supplied from the water collecting unit 50 is filtered through the water collecting unit 60 to remove foreign substances.

That is, as shown in FIGS. 3 and 5, rainwater flows into the body 61 through the first, second, and third pipes 55, 56, and 58, wherein the first pipe 55 Rainwater flows directly into the body 61 through the descending rainwater, but the second and third pipe lines 56 and 58 are installed at right angles to each other, so that the rainwater flows into the third pipe by driving the pump 57. It is introduced into the body 61 through the 58.

Rainwater introduced into the body 61 is first filtered by the gravel layer 63 in the first partition wall 62a, and then the rainwater is filtered by the sand layer 64 provided at the bottom of the gravel layer 63. . Rainwater is then filtered by the filter medium 65 which spans the 2nd partition 62b and the 3rd partition 62c.

As described above, the rainwater is bent through the gravel layer 63, the sand layer 64, and the filter medium 65 to filter foreign matters, and afterwards, the filtered water is stored in the rainwater storage unit 70, and at the same time, the rainwater is ground. The direct circulation method of water exchange, which is a heat exchange method, is used for cooling, heating, and water in buildings.

At this time, the rainwater storage unit 70 is used as a heat source of the geothermal heat pump 80 by using underground heat (10 to 20 ° C.), and the geothermal heat pump 80 is a pen coil unit connected to the pipe 81 ( 82) to adjust the temperature of the air supplied to the interior of the building (supply temperature 50 ~ 40 ℃ → discharge temperature 40 ~ 30 ℃), the supply pipe 75 supplies the living water where necessary for agriculture or buildings The pipe 73 penetrates the center of the rainwater storage pipe 71 to supply cold and hot air (10-15 ° C. in winter / 15-20 ° C. in summer) using underground air heat to the building.

This will be described in more detail as follows.

That is, the filtered rainwater is introduced into one of the rainwater storage pipes 71 through the fourth conduit 66 and then flows into the other rainwater storage pipes 71 through the communication pipe 72. .

And as shown in Figure 6 the water level sensor 77 is to detect how much water in the rain water storage pipe 71, which is the geothermal heat if the rain water is empty in the rain water storage pipe 71 Since it is not possible to exchange heat to the pump 80, it is necessary to secure a minimum amount of exchange water, and then, after purifying the rainwater through the filters 74 and 74a, the supply pipe 75 and the circulation pipe 76 are respectively Through the air.

The water discharged into the supply pipe 75 is water required for agriculture or buildings (eg, washing machines, toilets, showers, washing, cooking and drinking, washing, cleaning, garden water, etc.) by driving the rainwater pumping pump 75a. Will be supplied.

In addition, the water discharged into the circulation pipe 76 is introduced into another rainwater storage pipe 71 through the geothermal heat pump 80, wherein the water is introduced when the discharged water is about 8 ℃ by heat exchange It is introduced at about 5 ° C.

In addition, the geothermal heat pump 80 is connected to the pipe 81 to circulate the water, as well as the air supplied to the interior of the building using the pen coil unit 82 connected to the pipe 81 as described above. Temperature (supply temperature 50-40 ℃ → discharge temperature 40-30 ℃) is controlled.

In addition, the present invention is to introduce the outside air in the summer through the air inlet and discharge unit 90 or to discharge the internal air in the winter, the bent pipe 93 and the pipe (by driving the blowing and vent motor 94) 73) and the air is introduced and discharged, and in particular, the pipe 73 is installed to pass through the center of the rainwater storage pipe 71, and thus can be used in parallel with cold and warm air using underground air heat. This will be.

As a result, the present invention can obtain the results shown in Tables 1 and 2 below.

As described above, the present invention is to use the water for agriculture, living water, etc. by storing the rain water so as to significantly reduce the water.
