Definitions

  • the present invention relates to a ski hall with a with snow-covered, sloping floor and with a Cooling device to which laid along the floor surface and connected to cooling pipes through which a coolant flows to cool the hall floor.
  • ski halls In recent years, especially in Holland and Belgium a number of ski halls have been built there enable winter sports even in these lowland regions such as skiing, snowboarding etc. to operate.
  • a ski hall is basically an oversized cold store, whose bottom surface is designed as a ski slope and through Snow cannons are covered with snow.
  • the efforts go there, an equally good one
  • the object of the invention is a ski hall of the beginning to create mentioned type that is simple and it allows the air temperature with little effort and regulate moisture in the ski hall.
  • Cooling tubes from at least part of their length Step out of the floor surface or laid on the floor surface are, and that protective elements are provided between the cooling tubes are anchored to the floor surface and protrude above the cooling tubes to avoid damage to prevent the cooling pipes.
  • the invention is based on the consideration of the cooling tubes not to be laid in the floor as in the prior art, but on the surface of the ground, so that they operate immediately with the layer of snow lying on the floor come in contact to cool them. So it won't the hall floor, but rather the layer of snow cooled, thus providing additional insulation to the floor forms and on the other hand can be used to Regulate air temperature and humidity in the ski hall. For example, if you assume that the Layer of snow in a ski hall about a weight of 3,000 t, this layer of snow can be reduced the temperature around 1 ° C around 1,600 kWh of cooling energy take up. This energy is usually sufficient to the one entering the ski hall through the floor insulation To compensate for heat.
  • the snow temperature can also provide the energy be provided, which is required during the day to to cool the air in the ski hall.
  • the humidity can also be reduced regulate in the hall in a simple way. If namely the snow temperature below the air temperature holds, this leads to condensation of the air humidity on the snow, and in the opposite case, one will Sublimation of moisture reached by the snow, when the air is colder than the snow.
  • the ratio of Snow temperature to air temperature also humidity regulate in a simple way.
  • Protective elements are provided, through which it is prevented that the cooling pipes, for example, when passing over a Snow groomer can be damaged.
  • These protective elements are expediently formed like strips and laid along the cooling tubes, for example a trapezoidal profile with tapering towards the top Can have cross-section. With a suitable distance of Protective elements already offer sufficient protection Protection for the cooling pipes.
  • each still several across arranged protective elements are provided so that the protective elements form a protective grille.
  • This Protective elements arranged transversely to the cooling tubes can anchored to the floor surface, in particular screwed down his.
  • there is also a fixation along the Protection elements running cooling pipes conceivable. Conveniently, can run here transverse to the cooling tubes and used these spanning protective elements to position the cooling tubes on the floor surface and also to fix if necessary. hereby additional measures become superfluous.
  • the bottom surface in its longitudinal direction or transverse direction divided into several cooling sections and the cooling tubes of the cooling sections are in accordance with Art connected in parallel to the cooling device are so that they operate independently can be and especially in the individual Cooling sections also different depending on the need Cooling performance can be provided.
  • each cooling section has its own control loop with a temperature sensor and one provided on the inlet side Valve assigned so that in the individual Cooling sections different cooling capacities for setting the desired snow temperatures over the length the floor area can be generated.
  • This ski hall has one rectangular base and includes an outer skin 1 with Side walls and a roof and a floor area 2, the an essentially closed and thermally insulated Form space. In particular, is on the bottom surface 2 thermal insulation is provided.
  • cooling pipes 5 are laid along the bottom surface, which via connecting lines 4a, 4b and a pump 5 a cooling device 3 are connected and via this for cooling a layer of snow lying on the bottom surface 2 S with a coolant such as glycol be supplied.
  • a cooling device 3 are connected and via this for cooling a layer of snow lying on the bottom surface 2 S with a coolant such as glycol be supplied.
  • a cooling section formed, which according to Art a parallel connection to the connecting lines 4a, 4b are connected and a valve on the inlet side 6, via which the amount of coolant flowing through and thus regulates the cooling capacity in the cooling section can be.
  • Each cooling section is a control loop assigned over which the cooling capacity depending from the snow temperature by a temperature sensor is recorded, is regulated.
  • cooling tubes 5 meandering between the two long sides of the bottom surface 2, i.e. their main orientation is transverse to the longitudinal direction of the slopes.
  • the cooling tubes can of course also run in the longitudinal direction of the ski slope, the Cooling tubes can then be controlled individually or in groups can.
  • Cooling tubes 5 above the bottom surface 2 in the snow layer S relocated. This makes them susceptible to damage for example by a snow groomer, which groomed the ski slope.
  • protective elements 9, 10 intended. Firstly, extend between the cooling tubes 5, i.e. transverse to the longitudinal direction of the slopes, protective strips 9 with a trapezoidal shape that tapers towards the top Cross section anchored to the bottom surface 2 are and protrude above the cooling tubes 5. The distance between the protective strips 9 is between 20 and 40 cm, causing damage to the pipes practically excluded by a snow cat running over it are.
  • Protective webs 10 are provided, which in the longitudinal direction of the slopes run and each between two neighboring Protective strips 9 extend. Like especially the figures 3 and 4 clearly show, are the protective webs 10 their end faces on the flanks of the protective strips 9 and are anchored to the hall floor, screwed here. Point to their underside facing the bottom surface 2 the protective webs 10 recesses 11 for the cooling tubes 5 on, so that the cooling tubes 5 through the protective webs 10 the bottom surface 2 are positioned and also fixed.
  • ski hall 1 Snow generator 7 in the form of snow cannons and air coolers 8 provided for cooling the hall air.
  • the Snow generator 7 and the air cooler 8 are in one Metal structure 12 below the hall roof along the Ski slope at regular intervals of around 25 to 50 m attached to each other, each with a snow gun 7 and an air cooler 8 form a functional unit and are coupled in such a way that when commissioning a snow generator 7, the associated air cooler 8 runs at maximum performance. Otherwise everyone is Air cooler 8 a control loop with a temperature sensor assigned the cooler performance depending on the air temperature in the immediate vicinity of the Air cooler 8 regulates. In this way, the profile of the Air temperature in the ski hall in a desired manner can be set.
  • the setting is expediently carried out in such a way that at all five the temperature measuring points, i.e. over the entire length of the ski hall, sets the same temperature. This can difficult to control air circulation in the hall, which are due to temperature differences, largely be prevented.
  • the air inside the ski hall 1 is on the one hand from the bottom over the snow layer S and on the other hand via the air cooler from the ceiling side cooled.
  • the snow layer S through the cooling pipes 5 cooled down to a desired temperature be available to the required cooling energy to deliver.
  • By cooling over the snow layer S is achieved that along the entire floor area essentially sets a uniform temperature. If the snow temperature is below the air temperature is the additional effect that the in moisture in the air on the snow surface condensed. Conversely, moisture sublimes from the snow to the air when the snow temperature is above the air temperature.
  • cooling takes place by the air in the Ski hall is cooled via the air cooler 8, namely especially during snow production.
  • the control loops the air cooler 8 are set so that over the entire length of the ski slope in the upper hall area sets the same temperature. In this way become undesirable air circulation due to temperature differences avoided and on inside the hall each snow producer 7 equal conditions for that Snow creation created. This leads to an even good snow quality over the entire length of the ski slopes.
  • cooling takes place in the fresh air pre-cooled by cold exhaust air (heat exchange or mixing) and through the cooling units to the desired one Is brought into the hall becomes.
