Definitions
- the invention relates to a ski tunnel for operating cross-country skiing on natural or Artificial snow.
- Such ski tunnels allow cross-country skiing independently of the respective weather conditions, especially in weather conditions or during the seasons, when there is usually no snow outdoors becomes.
- ski tunnels and ski halls for practicing alpine skiing and Nordic cross-country skiing. They regularly have a floor and a superstructure on, the one to the outside world essentially climatically closed Form interior.
- a cooling floor which is traversed by a suitable coolant. On this chilled floor, the snow is applied for practicing the skiing and cooled on the bottom side.
- ski halls with air conditioning and / or to provide ventilation systems for the treatment of indoor air.
- DE-OS 102 61 716 A1 discloses a ski tunnel, in which above the cooling floor additional cooling elements are mounted. Cooling bottom and cooling elements are dependent Controlled by the conditions in the building to desired snow conditions or to preserve the snow in its consistency.
- DE 201 09 268 U1 discloses a ski hall having a substantially closed thermally insulated space forms. By suitable design of the roof as well as appropriate arrangement of air coolers and Schneerzeugern should the Making artificial snow of better quality possible.
- US 5,327 738 discloses methods for making and maintaining an artificial snow layer in a ski hall where the humidity is controlled by an air conditioner is controlled. From US 6,079,161 a ski hall is known in the by a suitable ventilation system above the snow surface layers of different Air temperature can be established.
- ski tunnels or ski halls have a number of disadvantages. For one thing, the snow in them can not last for a long time in good Quality will be preserved. Rather, it comes in the previously known ski tunnels or Ski halls to a comparatively fast metamorphosis of the snow to ice.
- This snow metamorphosis is also known from nature. Examples from nature are the formation of harsch or ice formation in glaciers. faster the snow metamorphism, which is detrimental to snow quality, is subject to variations the snow temperature, by a temperature gradient in the snow pad, due to warmer air over the snow than the snow temperature as well as by air flow (wind) over the snow. In the previously known ski halls or ski tunnels it is not possible to control the aforementioned factors in such a way that the snow metamorphism is delayed as much as possible.
- ski tunnel or ski halls have the disadvantage that it is not possible to produce exactly defined snow and climate conditions. However, this is desirable in the ski tunnel for snow and climate conditions to be able to simulate a particular competition site.
- a ski tunnel is proposed be who does not have the aforementioned disadvantages.
- the aim is therefore a Ski tunnel, where the snow brought in as long as possible in good Quality is maintained.
- the ski tunnel according to the invention to produce certain, well-defined snow and climate conditions, for example, the competition conditions of a certain competition location to simulate.
- the object is achieved in that an inner surface cooling for cooling the interior surfaces of the superstructure facing the interior of the tunnel is provided.
- This inner surface cooling is designed to cover the inner surfaces the superstructure substantially full surface cools.
- the task will continue achieved in that the temperature and humidity of the indoor air with the help of the air conditioning are independently adjustable.
- the inner surface of the superstructure Due to the internal surface cooling the inner surface of the superstructure can be tempered over the entire surface, the is largely brought in its full surface to a preselected temperature or cooled down. In particular, the inner surface of the superstructure over the entire surface to the same temperature as the indoor air. Thereby on the one hand the condensation and ice formation on the inner wall of the superstructure largely avoided. On the other hand, the warming of the near the Interior wall avoided air. Due to the full-surface cooling of the soil with the cooling bottom and the full-surface cooling by means of the internal surface cooling if all components relevant for the interior climate of the ski tunnel are thermally activated, that is, they can be brought to a preselected temperature.
- the complete thermal activation of the relevant components allows the Avoidance of undesirable climatic effects, as the boundary conditions of the climate system in the tunnel interior can be specified almost completely. In particular, the air temperature generated by the air conditioning and humidity levels in the tunnel interior are better maintained. Furthermore, the complete thermal activation of the components allows in combination with the air conditioning a targeted and accurate adjustment of the temperature of the air above the snow. By regulating the cooling floor can also the snow temperature can be controlled.
- the thermal activation of the components in combination with the air conditioning system thus allows the desired climatic conditions and actually achieve the desired snow temperature in the interior and to sustain for a long time, even if - for Seasonal example - the outdoor climate is fundamentally different. moreover can be achieved over the entire tunnel length constant conditions. So especially for snow metamorphosis by influencing the responsible Factors are significantly delayed. Furthermore, the snow and climatic conditions of certain competition forums.

This way becomes a frequent or permanent freezing of the foundation or foundation of the tunnel prevented. As a result, the durability of the ski tunnel can be increased because frost substructure and foundation damaged.

- the Ventilation system is connected to the air conditioner and serves for the supply air-conditioned air and its distribution inside the tunnel.
- the ventilation system is guided along the longitudinal direction of the tunnel and points several outlets distributed over the length of the tunnel. These outlets are distributed so that by supplying the conditioned air, an air flow or a draft across the surface of the snow introduced as much as possible is avoided. This can be achieved in particular by the fact that the Outlets in tunnel longitudinal direction are set at sufficiently close intervals.
- the ventilation system is designed as a pipe system along of the tunnel, preferably over the entire length, is guided.
- Outlets are designed as pipe end pieces, which turned in all directions, have small holes, so that the exiting air as evenly as possible in several spatial directions flows. Due to the aforementioned improvements of Ventilation system transforms the metamorphosis of snow into ice through draft the snow surface is reduced.
- the ventilation system is opposite isolated from the tunnel room. This prevents it to a thermal Exchange between the air in the interior of the tunnel and the still in the ventilation system located conditioned air comes before the conditioned air through the outlets into the tunnel interior. In this way it is achieved that the conditioned air with the temperature generated by the air conditioning or Moisture reaches the outlets of the ventilation system.
