Abstract
Description
Die vorliegende Erfindung betrifft eine Skihalle mit einer geneigten, zu beschneienden Bodenfläche, welche eine Skipiste bildet, mit mehreren Schnee-Erzeugern, die längs der Skipiste mit Abstand zueinander angeordnet sind, um die Skipiste zu beschneien, und mit mehreren Luftkühlern, um die Luft in der Skihalle zu kühlen.The The present invention relates to a ski hall with a sloping, to be snowed floor area, which forms a ski slope, with several snow producers who along the Ski slope with spaced apart are to the ski slope too snow, and with several air coolers to the air in the ski hall to cool.
In den letzten Jahren sind insbesondere in Holland und Belgien eine Reihe von Skihallen gebaut worden, die es ermöglichen, auch in diesen Flachlandregionen Wintersportarten wie beispielsweise Skifahren, Snowboarden etc. zu betreiben. Bei einer solchen Skihalle handelt es sich im Grunde genommen um ein überdimensionales Kühlhaus, dessen Bodenfläche als Skipiste ausgebildet ist und durch Schneekanonen beschneit wird. Beim Betrieb solcher Skihallen gehen die Bestrebungen dahin, eine gleichmäßig gute Schneequalität in der Halle zu erzielen und dazu optimale Verhältnisse für die Schnee-Erzeugung herzustellen. Zu diesem Zweck werden in den existierenden Skihallen unterschiedliche Maßnahmen getroffen. Beispielsweise wird die Lufttemperatur und -feuchte in der Halle reguliert und werden Vorkehrungen getroffen, um die enormen Energiekosten, die mit der Schneeherstellung und der Beibe haltung der erforderlichen kalten Atmosphäre verbunden sind, in Grenzen zu halten.In In recent years, especially in Holland and Belgium, one is Series of ski halls have been built, which make it possible even in these lowland regions Winter sports such as skiing, snowboarding etc. to operate. Such a ski hall is basically taken to an oversized Cold storage, its bottom surface is designed as a ski slope and is snowed by snow cannons. In the operation of such ski halls, the efforts go there, a consistently good snow quality to achieve in the hall and to create optimal conditions for the snow production. For this purpose, the existing ski halls are different activities met. For example, the air temperature and humidity in The hall regulates and precautions are taken to the enormous Energy costs associated with snow production and preservation the required cold atmosphere are connected, within limits to keep.
So
wird in der
Ein Problem, das bei den bestehenden Skihallen immer wieder auftritt, besteht darin, daß die Schneequalität über die Länge der Piste nicht gleichbleibend gut ist, sondern erheblichen Schwankungen unterliegt.One Problem that occurs again and again in existing ski halls, is that the snow quality on the Length of Slope is not consistently good, but is subject to significant fluctuations.
Aufgabe der Erfindung ist es daher, eine Skihalle der eingangs genannten Art so auszugestalten, daß über die Länge der Piste eine im wesentlichen gleichbleibende Schneequalität erreicht wird.task The invention is therefore a ski hall of the aforementioned Style to design so that over the Length of Piste reaches a substantially consistent snow quality becomes.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß den Luftkühlern getrennte Regelkreise mit jeweils einem Temperatursensor zugeordnet sind und die Luftkühlerleistung der Luftkühler unabhängig voneinander und jeweils in Abhängigkeit von der am Luftkühler gewünschten Lufttempera tur regelbar ist. Durch diese Maßnahme lassen sich die Temperaturverhältnisse in der Skihalle insbeson dere zu Zeiten der Schneeherstellung optimal einstellen mit dem Erfolg, daß die Qualität des hergestellten Schnees in der gesamten Halle gut ist. Tatsächlich haben Untersuchungen ergeben, daß bei den bekannten Skihallen die Lufttemperatur über die Länge der Skipiste deutlich schwankt mit der Folge, daß es zu schwer kontrollierbaren und daher unerwünschten Luftzirkulationen kommt, welche wesentliche Ursache für die Probleme bei der Schneeherstellung sind. Durch die erfindungsgemäßen Maßnahmen können nun diese Luftzirkulationen verhindert werden. Zweckmäßigerweise ist hierzu vorgesehen, daß die Regelkreise der Luftkühler die Kühlerleistungen in der Weise regeln, daß sich an den Temperaturmeßpunkten jeweils die gleiche, im wesentlichen frei vorgebbare Temperatur einstellt.These Object is inventively achieved in that the air coolers separate Control circuits are each associated with a temperature sensor and the air cooler performance the air cooler independently of each other and in each case depending from the air cooler desired Air temperature is regulated tur. By this measure, the temperature conditions can be in the ski hall, in particular at times of snow making optimal set with the success that the quality the produced snow is good throughout the hall. Actually have Investigations show that in The well-known ski halls the air temperature varies significantly over the length of the ski slope with the consequence that it comes to difficult to control and therefore undesirable air circulation, which essential cause for the problems with snowmaking are. By the measures according to the invention can now these air circulation can be prevented. Conveniently, is provided for this purpose that the Control circuits of the air coolers the coolers in the way that fix themselves at the temperature measuring points each sets the same, essentially freely definable temperature.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß jedem Schnee-Erzeuger ein Luftkühler zugeordnet ist. Auf diese Weise wird sichergestellt, daß zumindest an den Schnee-Erzeugungspunkten jeweils gleiche Verhältnisse für die Schneeherstellung vorliegen. Dabei sollten die Schnee-Erzeugungspunkte nicht zu weit auseinander liegen. Als ausreichend hat sich erwiesen, wenn die Luftkühler und/oder Schnee-Erzeuger in Abständen von etwa 25 bis 50 m entlang der Skipiste vorgesehen sind.According to one preferred embodiment of Invention is provided that each Snow producer an air cooler assigned. This ensures that at least at the snow production points in each case the same conditions for the Snow production. This should include the snow production points not too far apart. As has been proven sufficient, though the air coolers and / or snow producers at intervals from about 25 to 50 meters along the ski slope are provided.
In bevorzugter Weise sind weiterhin Mittel vorgesehen, um die Frischluft vor ihrem Eintritt in die Skihalle zunächst durch Wärmetausch und/oder Vermischung mit Kaltluft, welche aus der Skihalle abgeführt wird, vorzukühlen und dann mittels Kühlaggregaten auf eine gewünschte Ein trittstemperatur zu kühlen. Durch diese regenerative Nutzung der Energie der abgeführten Kaltluft kann der Energiebedarf für die Luftkühler gesenkt werden.In Preferably, means are further provided to the fresh air before entering the ski hall, first through heat exchange and / or mixing with cold air, which is discharged from the ski hall, pre-cool and then by means of cooling units to a desired To cool a running temperature. Through this regenerative use of the energy of the discharged cold air can the energy needs for the air coolers be lowered.
Im übrigen ist es zweckmäßig, wenn die Luftkühler und/oder Kühlaggregate jeweils eine Entfrostungsautomatik aufweisen. Auf diese Weise kann ein störungsfreier Betrieb gewährleistet werden.Otherwise it is it is useful if the air coolers and / or refrigeration units each have a defrosting automatic. This way you can a trouble-free Operation guaranteed become.
