DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an artificial ski resort, and in particular to an improvement of an artificial ski resort that is applied to an indoor artificial ski resort to retain root snow. [Prior art] Firstly, artificial ski resorts utilize cold regions or winter seasons.
It is operated by using snow guns or crushed ice to create artificial snow on slopes. However, recently there have been demands to be able to operate it year-round and to establish a large e-ski resort within the city. This type of conventional artificial ski resort has an indoor structure, cools the indoor space, and then uses a snow gun or sprays with crushed ice to form a downhill slope by applying artificial snow to the sloped floor. are doing. [Lid to be solved by the invention] However, in the above-mentioned conventional artificial ski resorts, artificial snow is applied to the sloped floor to form a downhill slope with a substantially constant layer thickness, Since it is extremely difficult to maintain the temperature of snow below the t8 melting temperature of snow, it is important to prevent the snow layer from melting! ! l! It was a topic.
In particular, the intrusion heat that reaches the snow layer from beneath the floor of a sloped floor surface causes an avalanche phenomenon into the snow layer, which is extremely dangerous. In other words, conventional artificial ski resorts had the disadvantage of not being able to retain deep snow. The purpose of this invention is to prevent heat from entering from under the floor by installing cooling pipes, and to prevent avalanche phenomena caused by the flow of snow melt on the sloped floor surface and the sliding of the upper snow layer. The purpose is to provide ski resorts. [Means for Solving the Problems] In order to achieve the above object, the artificial ski resort according to the present invention forms a sloped floor surface in the building, and forms a layer of snow on this sloped floor surface by a snow-falling means. At the artificial ski resort where formal discipline is practiced,
Surface cooling pipes were installed on the +1J1 sloped floor surface to directly cool the lower layer of snow. Further, as an artificial ski resort according to a second invention, the cooling pipe is laid along the direction intersecting the IIJI diagonal direction of the sloped floor surface, and an uneven part of the snow layer to prevent slipping is formed on the floor surface. .. [Function] According to the above configuration, the heat intruding from the sloped floor surface is absorbed by passing the refrigerant through the cooling pipe, thereby preventing the snow layer on the floor surface from melting. This prevents the avalanche phenomenon caused by melting in the lower layer of the In snow layer, but furthermore, in the second invention, the cooling pipes are arranged to intersect with the sloped floor surface to form unevenness on the floor surface. This prevents the snow layer from slipping due to uneven floor surfaces, and also prevents snow melt from flowing to the snow area below and expanding the melt area. Therefore, overall avalanche phenomenon can be effectively prevented and safety is high <4n.
This makes it possible to create an artificial ski resort that retains snow well. In this case, the amount of heat that has entered from under the floor can be extracted by 3'Z, so it is easy to install a cooling system that supplies the necessary refrigerant by laying cooling pipes to remove this amount of heat that has entered. [Example] Hereinafter, a specific example of the large e-ski resort according to the present invention will be described in detail with reference to the drawings. Fig. 1 shows the overall configuration of the artificial ski resort according to the embodiment, and Fig. 2 shows a sectional view of the floor structure. As shown in the figure, in the artificial ski resort according to the embodiment, an indoor air suction port 14 is opened in the ceiling work 2 of Kenjiio, and the sucked air is supplied to the air cooler 16. The air cooler 16 performs heat exchange to make the intake air into a cold state, which is then returned to the room of the building 10 from the discharge port 1B, which is also opened in the ceiling 12, to maintain the indoor temperature at a constant low temperature. There is. The floor surface of the building 10 is designated as an inclined floor surface 20 (11) for sliding downhill, and specifically, as shown in FIG. It is constructed by laying a waterproof sheet material 26 on top of it, and then pouring pressed concrete {F?!J28} on top of that.In addition to the construction of general artificial ski resorts,
In the artificial ski resort according to this embodiment, a cooling pipe 32 for cooling the snow Ji 30 is installed on the surface of the sloped floor surface 20, that is, on the upper surface of the holding concrete layer 28. The cooling pipes 32 are arranged in parallel so that their pipe axes run in a lateral direction that is substantially orthogonal to the direction of inclination of the inclined floor rm20, and by connecting the ends of adjacent pipes, a continuous piping configuration along the inclined surface is achieved. It has become. In this case, as shown in FIG. 2, the distance between the parallel cooling pipes 32 is kept constant by means of fixing fittings 33, and the arrangement of the cooling VFs 32 is prevented from collapsing due to the fffffi of the snow layer 30. By laying this cooling pipe 32, the inclined floor surface 2
0 has an uneven surface formed by the cooling pipe 32, and has a function of preventing the snow layer 30 from slipping. Brine 3 as a refrigerant for the cooling pipe 32 as described above.
4 is supplied by a pump 38 from a brine tank 36 to the end of the cooling pipe below the inclined floor surface 20. And the inclined floor surface 2
The brine 34, which has been cooled by the amount of snow accumulated in the brine tank 36 from the cooling pipe end located above 0, is returned to the brine tank 36. Brine tank 36
Heat exchange equipment is installed to recool the brine 34 returned to the reactor. This equipment is connected to a brine tank 36 and installed in the middle of a circulation path 38 that supplies brine 34. 2340, and the brine is returned to the brine tank 36 while being recooled by the circulation bomb 42. Further, the refrigerant that performs heat exchange with the brine 34 in the brine refrigerator 40 is circulated via a bomb 46 with a cooling tower 44 installed outdoors. The operation of an artificial ski resort with this structure is as follows. First, the air cooler 16 is operated and the suction port l4 is
, cools the indoor space 48 through the discharge port l8 to a temperature at which snow can be made. Next, snow is made using a snow gun or an ice crusher, and the snow falls on the slope surface 20 around 1 to form a snow layer 30. If the snow layer is thick enough for sliding down, use it. On the other hand, snow has poor heat transfer and the cold and heat in the indoor space 48 does not reach the floor surface. Heat from the outside temperature enters from under the floor as intrusion heat. This may cause the snow in contact with the bed to melt. In this embodiment, since the cooling pipe 32 is installed, one eruption slope floor 20
This prevents heat from penetrating from under the floor of the snow layer 30 and prevents the lower layer of the snow layer 30 from melting. As a result, the snow layer 30 does not melt and becomes stable. Furthermore, the snow layer 30 on the sloped floor surface 20 slides downward. In order to prevent this, in this embodiment, the inclined floor surface 2
The cooling pipe 32 creates uneven parts on the surface of the snow layer 3.
The downward sliding force of the 0 is supported by its uneven parts. Further, in the above embodiment, the pipe axis of the cooling pipe 32 is located at the inclined floor surface 2.
Since it is set so that the direction is perpendicular to the oblique direction around 0 to 1, the snow layer 30h<? The 8-digit water does not flow downward along the sloped floor surface 20, but instead flows to the side or becomes ice due to the action of the cooling pipe 32. Therefore, melting of the snow layer 30 due to the flow of water is reliably prevented. [Effects of the Invention] As explained above, according to the artificial ski resort of the present invention, cooling pipes are installed on the sloped floor surface to cool the lower layer of the snow layer, so that heat intrusion from under the floor is reduced. This can effectively and reliably prevent the snow layer from melting. In addition, the installed cooling pipes form unevenness on the surface of the sloped floor, and the engagement of the unevenness can prevent the snow layer from slipping, preventing so-called avalanche phenomena and preventing melt water from flowing downward. Since there is no snow melting effect, a higher snow melting prevention effect can be obtained.
