Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method of exchanging heat with melting cold water of snow, which is a natural cold resource, and a method of insulating and shading snowy mountains.

[0002]

2. Description of the Related Art To take out cold heat from a mass snow accumulating snow dam piled up on a pyramid body, heat is exchanged with secondary water through a pipeline laid beforehand at the bottom of the snowy mountain, or molten cold water is taken out to remove heat. Most of them were introduced into the exchanger to extract cold heat. Also, the method of snow accumulation is based on a trapezoidal pyramid shape, and rice husks, straw materials, and other bark materials are covered as they are, and nets are used to prevent wind damage.

[0003]

In the case of a large amount of snow storage snow dams, the load on the snow is large, and direct piping or shallow embedding at the bottom of a snow mountain may impede snow storage work or cause damage when vehicles enter and exit. Was an unstable factor. There has been a demand for a method of heat exchange with molten cold water, which can solve the easiness of snow-loading and the uneasiness of weighting and can stably take out cold heat.

[0004]

[Means for Solving the Problems] The bottom of the snowy mountain is not affected by the load on the heavy snow and does not hinder the entry / exit of the vehicle for carrying in the snow. Arrange water collecting masses with sufficient depth at arbitrary locations, connect them to each other with water collecting pipes, connect the water collecting pipes from any position, discharge water to the outside far from the snow mountain bottom and discharge it . For cold heat extraction, heat exchange pipes and hoses are laid from the water pipe to the inside of the water collection pipe, and the secondary water flowing through this pipe is used to absorb cold heat for the purpose.

[0005] The conventional method of storing cold snowy mountains has been considered to be a truncated pyramid type or a heaping type. However, this method is not suitable for use in a town because the area occupied by the snow mountain becomes unexpectedly large. there were. When a sheet is used as the material for covering the light-shielding insulation of a snowy mountain, there are difficulties in wind obstruction, and it is difficult to concentrate rainwater from a seam of a sheet that has become a depression or a damaged portion. In addition, the method of covering with rice husks, straw materials, and bark materials has a stable familiarity with the wind when used in combination with nets. Although not available, it is difficult to use wet paddy and bark wood unless the wrapping material is located close to the grain production area, and it is difficult to use wet paddy and bark wood in a cycle. You will have

[0006] From these viewpoints, in the present invention, a three-sided snow storage area with an arbitrary orientation is opened, and snow is brought into the snow storage area to form cold storage. The three-way wall snow storage facility has a wall structure formed of a strength structural portion serving as a skeleton of a surrounding wall, and an inner wall formed of a heat insulating material and a surface protection material. Depending on the size of the bottom, a water collecting mass is arranged at an arbitrary position, and a gradient is taken toward the square to facilitate the collection of the molten water. In addition, the flat surface that is freely released forms a water stop slope at its release port, thereby preventing external leakage of molten water and entry of miscellaneous water from outside. This method makes it easy to store snow efficiently with a minimum site area, and can be used for general purposes in towns.

[0007] As for the covering material for snowy mountains, the use of rice husks and straw bark materials is disadvantageous for the above-mentioned reasons, and it is poorly used as it is. If the sheet material is too large, not only will wind damage and extreme leakage of rainwater be a problem, but the sheet wound by the wind will be blown to other places and cause secondary disasters, so it is poorly used. . Therefore, a strip-like elongated shape is also suitable for measures against wind damage, and these are connected to a minimum number of pieces to form a band-like covering material. As the covering material, a granular or flake-shaped material having poor moisture absorption is packed in a long hemp bag, or a thread-shaped or rope-shaped material is packed into a gabion body in a special processing to form a band-shaped covering material. By arranging the required number of band-shaped covering materials and applying several layers to them, it is similar to the use of paddy and straw bark materials, and is resistant to wind and uniformity of rainwater penetration.

Embodiments Embodiments of the present application will be described with reference to the drawings. FIG. 1 shows an example of heat collection and utilization of cold heat from a snowy mountain, in which a snowy mountain 1 is formed in a water stop 10 and a water collecting mass 3 is installed at an arbitrary position at the bottom thereof. And a water pipe 6 is connected from an arbitrary position in the water collecting circuit. The catchment trout is always full and fills both the catchment pipe and the conduit. Heat collection pipes 5 are provided in the water collection pipes around the water collection pipes, and the secondary water absorbs cold heat. The heat collection tube 5 is extended to the outside and used for cooling and heating. In the example shown, the operation load of the chiller unit is reduced and used for power saving purposes.
It is connected to the water channel of the cooling unit and uses a combined circuit with snow and cold. The water collecting pipe connecting the water collecting mass at the bottom of the snowy mountain is a U-shaped groove that is open at the top, and it is also effective to use a grating with a lid to remove the mud generated from the molten water and also facilitate maintenance. .

FIG. 2 shows the configuration of the above-described three-sided wall snow storage area. FIG. 3 shows the configuration of the band-shaped covering member, and FIG. The three-sided wall blocks the direct pressure of the wind, and the band-shaped cover has good ventilation, is resistant to wind damage, and evenly floods rainwater, preventing local perforation. Since the covering material according to the present application can be easily used over a long period of time, the cost is low and the difficulty of disposal is eliminated.

[0010]

According to the three-way wall snow storage system, snow mountain-type snow storage in a town area is facilitated, and the snow removal work in the surrounding yard leads to snow storage, so that the cost of removing snow is reduced. Since snow is piled up in two or three walls, there is no need for special heavy equipment, and there is no need to purchase new equipment, as it can be covered by general-purpose machines for private demand. 3. The belt-shaped snow cover is easy to handle and hard to be turned by the wind, so that it can be securely mounted. Also, since the rainwater is evenly flooded, it is difficult to form a leak hole. In addition, unlike the sheet cover, heat storage under the curtain is not possible, so the snow mountain can be stored well. 4. The use of molten water cooling and heat is easy to connect to many existing cooling systems, and it can be applied at low cost to water cooling circulating mechanisms such as chiller units as in the case, greatly contributing to the reduction of cooling power. .
