  • the invention relates to an indoor snow plant according to the preamble Claim 1.
  • Indoor snowmaking systems are also known in particular in the form of Indoor winter sports facilities, in the simplest case of a closed room or interior, namely a hall having a slope Hall floor, and from a snowmaking system with snowmaking equipment for snowmaking the hall floor.
  • the snowmaking devices are this essentially water atomizing nozzles, where water and air under Pressure are supplied and by spraying the water a water mist form, from which then arises when lowering on the hall floor snow.
  • the disadvantage is, inter alia, that the atomizer nozzles at a relatively high altitude above the Hall floor must be arranged, thus for the snow formation from the Water droplets are enough time available. But this also means big Hall heights and thus an excessively high hall volume, which by a Air conditioning to a necessary for the snow formation temperature of below 0 ° C. must be cooled. This disadvantage can be achieved by appropriate training Snow-making system to be corrected.
  • cooling system which consists essentially of a Floor laid and transported by a cold heat medium (cold brine) flowed through pipe system.
  • the object of the invention is to show an interior snow plant, in the with simple means both cooling and heating of the bottom of the plant is possible.
  • an indoor snowmaking system accordingly formed according to claim 1.
  • the interior snow plant according to the invention becomes one and the same Tube system used for cooling or for heating the soil, namely in that this pipe system is charged with either cold or warm brine becomes.
  • this pipe system is then a targeted Defrost the snow cover on the ground possible, for example, to Cleaning the snowpack.
  • By feeding the pipe system with the cold Sole is a targeted control of the snow temperature possible and thereby a targeted influence on the snow quality.
  • the training conditions can also be used here to be influenced.
  • the heating and cooling system is designed that for generating the warm brine the heat of condensation is used, the Generating the cold brine arises.
  • the capacitor is the Chiller cooled with the brine to be heated and then heated State stored in a suitable memory for further use.
  • An "indoor snow plant” or an “interior to be snowed” are in According to the invention basically any interior space, e.g. of a building, in the (interior) snow is to be generated.
  • An interior to be snowed is accordingly, for example, the hall of an indoor winter sports facility, but also e.g. an interior in which a testing and / or training device and / or track is housed.
  • the snowmaking system of at least one snowmaking device formed, the least one Water atomizing nozzle, which is supplied with water and compressed air. These Nozzle is then provided in a housing open at both ends, which of a Housing air flow is flowed through.
  • the housing air flow is for example the air flow of an air conditioner, e.g. taken from an indoor air conditioning, so an air flow that not only has a regulated temperature, but also a has more or less constant relative humidity.
  • the snow formation from the atomized water takes place in the invention within the housing of the snowmaking devices and thus in an air volume, which is separated from the rest of the air of the interior. This is a optimal snow formation especially at a relatively high humidity in the Interior possible. Furthermore, in the invention by the snow formation also the temperature of the hall interior is not or only imperceptibly influenced.
  • the generally designated 1 in the figure plant consists u. a. from one spacious hall 2, the hall floor 3 at least in a sub-area as Sloping or as a downhill slope for snow-skiing (skiing, snowboarding, etc.) is trained.
  • the hall floor 3 Above the hall floor 3 are on a ceiling construction or at another, suitable support structure of the hall 2 a variety of Beschneiungsvoriquesen 4 are provided, each consisting essentially of a at both ends open tubular housing 5 having a predetermined axial length, for example, with a length of 2 meters and from a nozzle arrangement with at least one atomizer nozzle 6, which in the region of an open end of the Housing 5 is provided.
  • the individual snowmaking devices 4 are with the Arranged axis of their housing 5 in the vertical direction, in such a way that the nozzles 6 are located at the upper open end of the respective housing.
  • the Housing 5 is flowed through by a housing air flow 7, the example of a blower 8 is generated.
  • the fan 8 which for example for each Snow-making device 4 separately or for a variety or for all Snowmaking devices 4 is provided together, sucks to produce the Housing airflow 7 cool and dry air.
  • the interior of the hall 2 is cooled to a temperature, which is in the range of 0 ° C, for example, below 0 ° C, so that then the air the housing air flow 7 this temperature in the range of 0 ° C or below 0 ° C. having.
  • each snowmaking device 4 on the one hand compressed air, the one has extremely low moisture and has a temperature well below 0 ° C, and on the other hand also supplied water under high pressure, the temperature at about 0 ° C.
  • the water with the dry and very cold Compressed air atomizes, so that strongly cooled small water droplets or a strongly cooled water mist 10 in the upper region of the respective housing. 5 form, which are entrained with the housing air flow 7 and from which then still within the housing 5 snow for snowing in particular of the Hall floor 3 forms.
  • a device 11 is provided, the air from the interior of the Hall 2 and thereby preferably sucks in the bottom of the hall, ie where the Air already has a low temperature.
  • the device 11 is the sucked air dried, compressed and cooled, so that the nozzles 6 supplied, cooled well below 0 ° C compressed air is obtained.
  • a device 12 which in the simplest Case consists of a boiler in which the device 12 supplied water as far as it is cooled, it is partly frozen in the boiler and partly still liquid is present for forwarding to the nozzles 6, under pressure by means of Pump 13.
  • the hall floor 3 To clean the hall floor 3, i. to remove soiled snow the hall floor 3 heated and provided with a drainage 14, with each of the lowest layer of the snow cover 15 on the hall floor 3 defrosted and on the Drainage 14 can be removed. Due to the reduced thermal conductivity of the Snow is this defrosting and removing the lower layer of the Schneebelags 15 also during operation of the plant 1 constantly or in predetermined intervals possible. Furthermore, the hall floor 3 is also cool, so that by this cooling e.g. Influence on the snow temperature and thus influence on the snow quality and the sliding or handling of skis, etc. or influence on training conditions can be taken.
  • this cooling e.g. Influence on the snow temperature and thus influence on the snow quality and the sliding or handling of skis, etc. or influence on training conditions can be taken.
  • the respective housing 5 of the Snowmaking device 4 by flowing outer casing air flow 7 of cold and dry air, e.g. from the air of an air conditioner. It exists here but also the possibility of the air for the housing air flow 7 from one of the Indoor air conditioning 9 generated and the interior of the hall 2 for example over to take a ventilation ceiling 18 supplied airflow 19. For this are then the housing 5 of the snowmaking devices 4 with its upper, open end a channel 20 is connected, via which the air of the hall air conditioner 9 before her Outlet on the ventilation ceiling 18 is distributed. In this embodiment, then Blower 8 omitted.
  • the use of the air conditioning 9 supplied air for the outer housing air flow 7 in the housings 5 also has the crucial Advantage that the snow formation by the snowmaking devices 4 at least largely independent of the relative humidity inside the hall 2 is.
  • the outer, the housing 5 of the respective Snowmaking device 4 by flowing housing air flow through a corresponding flow guidance, for example by baffles or others Deflection means vertebrae or spiral form, so as long as possible Retention time to achieve a shorter axial length of the housing 5.
  • the hall floor 3 can be heated and also is coolable.
  • the illustrated in Figure 3 and there generally with 21st designated Bodencream- and cooling system provided.
  • This system consists u. a. out a pipe system 22, which is laid in the hall floor 3, on a sufficiently dimensioned thermal insulation with double-sided vapor barrier.
  • the flow and return of the pipe system 22 are with a plurality of valves having connected control device 23, via which the pipe system 22nd optionally with a cold or warm brine can be charged, and indeed each from a sufficiently large storage tank 24 for the warm brine or out a sufficiently large storage 25 for the cold brine. Both stores 24 and 25 are provided with the best possible thermal insulation.
  • FIG. 3 Shown in FIG. 3 is also a schematic representation of a refrigeration machine 26, which is conventional Is formed and in the illustrated embodiment, the evaporator 27, the condenser 28, the collector 29, the compressor 30 and the throttle valve 31 exhibit.
  • the evaporator 27 is formed as a heat exchanger, for cooling the in the memory 25 stored cold brine is used.
  • In the capacitor 28 is as Heat exchanger formed, which is for heating the stored in the memory 24 warm brine serves.
  • the control device 23 is thus the pipe system 22nd optionally heatable and coolable, so that a targeted and controlled Defrosting the snow on the ground 3 as well as a targeted influence on the temperature of the snow on this ground are possible and over the Snow temperature influencing the quality of snow, which also different training conditions are possible.
