Description of the Related Art Due to the development and diversification of the leisure industry, there is a demand for skiing in a comfortable environment without being affected by the natural environment. To meet this demand, indoor ski slopes have been built, and are being added not only to cities and suburbs, but also to natural ski slopes so that skiing can be performed even in bad weather.

FIG. 7 schematically shows the interior of a building of a conventional indoor ski area.

In a conventional indoor ski area, as shown in FIG. 7, a slope 102 is formed inside a building 101 and is inclined in a direction perpendicular to the drawing.
Slope 104 is formed by snow covering 103 at a predetermined thickness. In the vicinity of the ceiling of the building 101, an air compression tube 105 is erected, and an air compressor 106 provided outside the building 101 is connected to the air compression tube 105.
A water pipe 107 is erected along the water pipe 107.

[0005] Therefore, the air cooling device 112 is about -10 to
The cold air of −15 ° C. is sent to the building 101 through the cold air supply pipe 110.
Let this cold air blow out inside. At the same time, air compressor
In addition to supplying compressed air to the air compression pipe 105 from 106, water is supplied from the water supply device 108 to the water supply pipe 107, and each injection nozzle 10
Inject from 9. Then, heat exchange is performed between the mist water and the cooled air, and the mist water becomes artificial snow 103 and falls on the slope 104. If such an operation is continued for a certain period of time, snow will accumulate on the slope 102 and the slope 104
Is formed.

[0006] The artificial snow 1 having a certain thickness is attached to the slope 102.

On the other hand, cool air is constantly blown from the cool air supply pipe 110 into the inside of the building 101, and even when artificial snow is not falling, the whole inside of the building 101 is reduced by about -5 to Cooled to around -10 ° C,
The snow quality of the artificial snow 103 can be favorably maintained by the compressed air and the water. That is, in order to maintain good snow quality of the artificial snow 103, it is necessary to maintain the temperature of the snow surface of the artificial snow 103 below a preset temperature (for example, 2 ° C.). In order to maintain the temperature at or below ℃, cold air was continuously blown out to cool the air temperature in the entire interior of the building 101 to about -5 to -10 ° C.

By supplying compressed air and water from the air compressor 106 and the water supply device 108 and injecting them with the injection nozzle 109, the mist water is turned into artificial snow 103 and deposited on the slope 104 to form a slope 104, In order to maintain good snow quality of the artificial snow 103 on the slope 104, cool air was supplied to the entire interior of the building 101 to cool it to around -5 to -10C.

However, in order to produce the artificial snow 103 inside the building 101 and deposit it on the slope 104,
The entire interior of the building 101 must be cooled, and the air cooling device 112 for supplying cool air to the inside of the building 101 requires a large capacity, which increases the size of the device and increases the energy cost. There's a problem.

[0010] In addition, there is a case where a family including a small child enters the indoor skiing area, and therefore, it is desired to provide a snow area where a small child can play with a snow or sled. In this case, it is necessary to deposit high quality artificial snow in the snow area as compared with the ski slope. However, in the conventional indoor ski area described above, the artificial snow 103 formed by cold air and mist-like water is simply sprayed on the slope 104, and the snow quality of the artificial snow 103 is preferably maintained. It is only necessary to supply cold air to the entire interior of the building 101 for cooling, and it is difficult to maintain the snow area with higher quality artificial snow.

The present invention has been made to solve such a problem, and an indoor type ski resort which aims to reduce the energy cost of facilities while maintaining a snow area provided on a slope with a better quality of artificial snow. It is an object to provide a different temperature space system.

Thus, the thickness of the artificial snow 16 on the slope 17 is always kept constant and good snow quality is maintained. That is, as shown in FIG. 4, the floor 12 of the dome 11 is made of concrete, and a concrete floor 32 is formed on the floor 12 via a urethane heat insulating material 31 as a heat insulating member.

Rises above the cool air flowing on the surface of the dome 11 and circulates along the ceiling 13 of the dome 11, and the inside of the dome 11 is partitioned into a normal temperature space area M and a low temperature space area C. A part of the airflow flowing through the ceiling 13 of the dome 11 passes through each discharge hole 26 and
7, the heat is exchanged (cooled), and the jet is again jetted from the jet nozzle 25 to the slope 17 side.

As shown in FIG. 4, the thickness of the urethane heat insulating material 31 is set in accordance with the amount of snow melting on the lower surface of the artificial snow 16 on the slope 17 of the indoor ski resort. The heat flowing through the floor 16, the urethane insulation 31, the concrete floor 32, and the artificial grass 33 acts on the lower surface of the artificial snow 16, and the lower surface of the artificial snow 16 melts. And the melt of artificial snow 16 is artificial grass 3
3 flows down from the through hole 35 into the molten water groove 34 and flows downward through the molten water groove 34.

In the snow making machine 18, when water (snow-melting water) is sprayed by pressurized water and compressed air while blowing cold air into the inside, heat exchange is performed between the atomized water and the cooled air. Artificial snow is manufactured and stored in the snow storage 19. Then, the artificial snow in the snow storage 19 is pressure-fed to the slope 17 by the compressed air in the snow carrier 20, and is sprayed on the slope 17 from a snow spray nozzle (not shown).
