Description

METHOD AND SYSTEM FOR MAKING ARTIFICIAL SNOW

FIELD [0001] The present invention relates to a method for making artificial snow.

[0002] Further, the present invention relates to a system for making artificial snow.

BACKGROUND [0003] It is known to make artificial snow to place it e.g. on ski tracks to compensate 10 for lack of natural snow or to supplement natural snow. For example, snowmaking is critical for winter sporting resorts, because the amount of snow and the period of time that snow is present dictate whether a resort has a financially successful season. The earlier and the longer the length of time snow is present, the longer persons are able to use a resort. Unpredictable weather patterns can produce winters with low outputs of snow.

[0004] Artificial snow may be, for example, produced using a so called snowgun.

Typically, the snowgun draws water in, and compressed air breaks it up into tiny particles. This process is called atomizing. The tiny water particles are subsequently blown up into the air. Under certain circumstances, some sort of nucleator is mixed into the water supply, so that the tiny water particles have something to bind to. If the temperature and the 20 humidity are appropriate, the water will crystallize into snow before gravity brings it to the ground.

[0005] Documents US 2015/0053785 Al, WO 2009/061722 A2 and WO 01/86216 Al, for example, disclose several methods and systems for making artificial snow. Generally, three different types of snowmaking systems are used, i.e. internal mixing 25 systems, external mixing systems, and fan guns.

[0006] An example air/water system is a snowgun that includes a nozzle that combines high amounts of compressed air and relatively low amounts of pressurized water. The compressed air and pressurized water are simultaneously discharged from the

20185182 PRH 27-02- 2018 snowgun. As the compressed air and pressurized water exit the snowgun, the expansion of air creates frozen nuclei, breaks up the water into smaller particles, and propels it across the slope. Cold ambient air completes the freezing process and causes the water to form into artificial snow. Such air/water systems are usually ineffective above a certain 5 temperature.

[0007] Another example system is a low-pressure snow cannon that includes a propeller for producing a main stream into which freezing nuclei are sprayed by means of nucleator nozzles and small water droplets are sprayed by means of water nozzles. The nucleator nozzles are constructed as water/air nozzles, and they are operated with 10 compressed air and water under pressure and atomize a water/air mixture. The compressed air relaxes as it issues from the nucleator nozzles und thus cools water droplets of the water/air mixture to well below the freezing point so that small ice crystals are formed. The droplets discharged by the water nozzles collide and/or intersect with these freezing nuclei and form snow crystals. Also such snow cannons are usually ineffective above a certain 15 temperature.

[0008] The water may be mixed with ina (ice-nucleation-active) proteins from the bacterium Pseudomonas syringae, for instance. Such proteins serve as effective nuclei to initiate the formation of ice crystals at relatively high temperatures, so that the droplets will turn into ice before falling to the ground. On average, such a material can increase the 20 amount of snow produced by a machine by 50 %. It also helps to produce lighter and drier flakes. The nucleating agent is a non-toxic and biodegradable protein. Also other chemicals may be used to initiate the formation of ice crystals at relatively high temperatures.

[0009] Production of artificial snow requires significant quality control measures.

Prior to production, the nucleating material is checked to ensure that it meets the 25 specifications. The artificial snow is further analysed for crystal quality, appearance, and wetness, while the snow is being made. The air/water ratio may be adjusted to improve the quality of snow. Snow of highest quality will last longer, hold its shape better, and be easier to groom.

[0010] It is further known to produce an artificial snow layer at indoor skiing slopes. 30 Production of artificial snow is possible year-round as a climate-controlled environment is provided. The production of artificial snow requires low temperatures. The threshold temperature for snowmaking increases as humidity decreases. The so called wet bulb temperature is used as a metric, since it takes into account air temperature and relative humidity. In such indoor facilities, the indoor temperature may be, for example, in the range between -6 °C and -10 °C. The relative humidity may be, for example, more than 60 %. The low temperature and the relative humidity are typically maintained during the 5 snow-layer forming operation and also during the actual use of the formed snow layer.

Document EP 0508752 B2, for example, describes a method of forming an artificial snow layer, and more particularly a method of forming an artificial snow layer at e.g. an artificial snow indoor skiing slope.

[0011] There is a need to provide artificial snow for outdoor use also outside of the 10 winter season, for example during summer. In such cases, artificial snow is produced at an indoor facility, for example, at an indoor skiing slope, and then transported to a desired location. However, such forming of artificial snow at an indoor facility and subsequent transportation of the snow to the desired location is complicated, time-consuming and expensive. Depending on the distance between the indoor facility and the desired location, 15 the temperature of the artificial snow has sometimes to be substantially maintained by using vehicles providing cooling. Several trucks or other vehicles may be further necessary in order to transport a serious amount of artificial snow to a desired location.

[0012] In view of the foregoing it would be beneficial to provide a method and system for making artificial snow, wherein artificial snow can be provided at a desired 20 outdoor location and at any time of the year without any transportation need.

BRIEF DESCRIPTION OF THE DRAWINGS [0021] FIGURE 1 illustrates a schematic top view of a system for making artificial snow in accordance with at least some embodiments of the present invention, [0022] FIGURE 2 illustrates a schematic top view of a system for making artificial snow in accordance with at least some embodiments of the present invention, wherein the building has been moved along the linear guiding, [0023] FIGURE 3 illustrates a schematic view of a container of a system for making artificial snow in accordance with at least some embodiments of the present invention, and [0024] FIGURE 4 illustrates a schematic explosion view of a building assembled from modules of a system for making artificial snow in accordance with at least some embodiments of the present invention.

EMBODIMENTS [0025] In this document, the expression “controlling a temperature within the building” means that a temperature within a building can be adjusted. Typically, the temperature within the building is first lowered to a specific temperature, where artificial 20 snow can be produced, and subsequently the specific temperature is maintained for a period of time. Similarly, the expression “first unit configured to control a temperature within the building” means that a system is provided by means of which a temperature within a building can be adjusted. Typically, the system is used to first lower the temperature within the building to a specific temperature, where artificial snow can be 25 produced, and to subsequently maintain the specific temperature for a period of time.

[0026] In this document, the expression “controlling a relative humidity within the building” means that a relative humidity within a building can be adjusted. Typically, the relative humidity within the building is first raised to a specific relative humidity, where artificial snow can be produced, and subsequently the specific relative humidity is

20185182 PRH 27-02- 2018 maintained for a period of time. Similarly, the expression “second unit configured to control a relative humidity within the building” means that a system is provided by means of which a relative humidity within a building can be adjusted. Typically, the system is used to first raise the relative humidity within the building to a specific relative humidity, 5 where artificial snow can be produced, and to subsequently maintain the specific relative humidity for a period of time.

[0027] In FIGURE 1 a schematic top view of a system 1 for making artificial snow in accordance with at least some embodiments of the present invention is illustrated. The system comprises a linear guiding 3, for example in the form of two parallel rails 15.

Further, the system 1 comprises a plurality of modules (not shown) which are configured to be assembled into a building 5. The building 5 is arranged on a part of the linear guiding 3 and movable along the linear guiding 3.

[0028] Furthermore, the system 1 comprises at least one first unit (not shown) configured to control a temperature within the building 5 and at least one second unit (not 15 shown) configured to control a relative humidity within the building 5. The first unit is necessary to provide a required temperature within the building 5, for example a wet bulb temperature of less than -1 °C, for producing artificial snow. The second unit is necessary to provide a required relative humidity within the building 5, for example of more than 60 %, for producing artificial snow.

[0029] The first unit may be a cooling device and the second unit may be a steam generator, for instance. The first unit and the second unit may be, for example, arranged in a container 16. A generator (not shown) for providing electrical power may be further arranged in the container 16. The container 16 may be located outside of the building 5 and the first and second units may be connected to the building 5 and/or devices located within 25 the building 5 via supply lines 17, for instance.

[0030] Additionally, the system 1 comprises at least one device 8 configured to produce artificial snow within the building 5. The device 8 for making artificial snow may be, for example, a so called snow gun, snow cannon, or snow lance. Such devices 8 for making artificial snow are known and commercially available. The device 8 may be an 30 internal mixing, an external mixing, a snow lance, or a fan gun. Typically, less energy is required for making artificial snow using snow lances. The lances are typically elongate, inclined aluminium tubes with water and/or air nucleators at the end. An air stream is

20185182 PRH 27-02- 2018 blown into the atomized water at the outlet of the water nozzle. Previously compressed air expands and cools, thus creating ice nuclei on which crystallization of atomized water takes place. Snowmaking additives may be further used. Examples of such additives are DRIFT® and Snomax®. The additives are typically injected into the snowmaking water by 5 means of an injection system.

[0031] When installing the system 1 at a desired location, the linear guiding 3 is typically first provided at the desired location. Subsequently, the building 5 is assembled from the plurality of modules and coupled with the linear guiding system 3 such that the building 5 is movable along the linear guiding 3. The first unit and the second unit as well 10 as the generator, which may be all arranged in the container 16, are further connected with the building 5 via supply lines 17, for instance. Further, at least one device 8 for producing artificial snow is placed within the building 5. The device 8 is furthermore connected to a pressurized air supply and a water supply.

[0032] Then, the temperature within the building 5 is controlled. Typically, the 15 temperature is lowered to a required temperature for making artificial snow. Additionally, a required relative humidity for making artificial snow is provided within the building. Finally, artificial snow 2 is produced within the building 5 using the device 8 for producing artificial snow. The temperature and relative humidity within the building 5 are typically maintained or substantially maintained during production of artificial snow. The threshold 20 temperature for snowmaking increases as humidity decreases. The wet bulb temperature is used as a metric, since it takes into account air temperature and relative humidity.

[0033] According to certain embodiments of the present invention, cloud seeding within the building can take place. In such a case, dosing the atmosphere within the building with silver iodide or carbon dioxide can be performed. Thus, ice crystals can be produced 25 at higher temperatures. Further, increased snow production can take place.

[0034] According to a certain embodiment of the present invention, artificial snow is produced mainly or only in a first section I of the building 5. The device for producing snow is then located in a second section II of the building 5.

[0035] In FIGURE 2 a schematic top view of a system 1 for making artificial snow 30 in accordance with at least some embodiments of the present invention is illustrated, wherein the building 5 has been moved along the linear guiding 3. Subsequently to

20185182 PRH 27-02- 2018 producing a first pile of artificial snow 2 as illustrated and described in connection with FIGURE 1, a part of the building 5 can be removed or opened and the building can be moved along the linear guiding as indicated by arrow A. Thus, the first pile of artificial snow 2 is located outside of the building 5. The removed part of the building 5 can then be 5 re-inserted or the building can be closed again, respectively. After lowering the temperature to the required temperature for making artificial snow and providing the required relative humidity for making artificial snow within the building 5, artificial snow 2 can be again produced within the building 5 using the device 8 for producing artificial snow.

[0036] The first pile of artificial snow 2 may be covered with an insulating material prior or after moving the building 5 along the linear guiding 3. Thus, melting of the produced artificial snow 2 can be delayed.

[0037] A serious amount of artificial snow 2 can be produced by moving the building 5 along the linear guiding 3, because the amount of artificial snow to be produced 15 is not depending on the size of the building 5.

[0038] The procedure described in connection with FIGURE 2 can be repeated, if required. The number of repetitions is depending on the length of the linear guiding 3. According to certain embodiments, a part of the building 5 can be removed or opened at both sides of the building 5. Thus, it is possible to move the building 5 back and forth, i.e. 20 in two opposite directions, along the linear guiding 5. In such a case, artificial snow 2 outside of the building 5 has to be removed, for example by using an excavator, in order to provide the capability of producing artificial snow 2 again, when changing the direction of movement of the building 5.

[0039] In FIGURE 3 a schematic view of a container 16 of a system 1 for making 25 artificial snow in accordance with at least some embodiments of the present invention is illustrated.

[0040] The container 16 comprises a part of a first unit configured to control a temperature within the building (not shown). The first unit may be, for example, a cooling device comprising a compressor, a heat exchanger, and a condenser. The compressor is 30 located within the container 16 and configured to raise a pressure of a refrigerant and to move it along into the direction of the heat exchanger. The heat exchanger is located within

20185182 PRH 27-02- 2018 the building 5. In the heat exchanger, the refrigerant goes through a plurality of tubes, which are surrounded by heat transfer fins through which cooling air can flow. The condenser is located outside of the building 5. One tubing is provided between the condenser and the building for vapour refrigerant entering the condenser and one tubing is 5 provided for liquid refrigerant leaving the condenser. A water cooling unit can use the same refrigerant system as the building cooling system.

[0041] Further, the container 16 comprises a second unit 7 configured to control a relative humidity within the building. The second unit may be, for example, a steam generator, which is connected to a steam connector 19, to which a steam supply line can be 10 connected (not shown). The steam supply line itself can be connected to the building so that steam can be guided into the building.

[0042] Furthermore, the container comprises a compressor 10 by means of which pressurized air can be provided. The compressor 10 is connected to a pressurized air connector 20, to which a pressurized air supply line can be connected (not shown). The 15 pressurized air supply line itself can be connected to a pressurized air supply center of the building so that pressurized air can then be guided to at least one device for making artificial snow (not shown) or directly to the device for making artificial snow.

[0043] Additionally, the container comprises a water pump 11 for controlling a water pressure. The water pump 11 is connected to a pressurized water connector 18, to 20 which a pressurized water supply line can be connected (not shown). The pressurized water supply line itself can be connected to a pressurized water supply center of the building so that pressurized water can then be guided to at least one device for making artificial snow (not shown) or directly to the device for making artificial snow.

[0044] The container 16 further comprises a generator for producing the required 25 electric energy for controlling the temperature within the building, for controlling the relative humidity within the building and for producing artificial snow.

[0045] The container 16 may also comprise a control unit 12 in the form of a computing device 13, for instance. The control unit 12 may be, for example, configured to monitor a water pressure, a water temperature, an air pressure, a temperature within the 30 building, and a relative humidity within the building. The control unit may therefore be connected to different measurement sensors such as a pressure sensor, a temperature

20185182 PRH 27-02- 2018 sensor, and a relative humidity sensor. The control unit may be configured to control at least one of the first unit, the second unit, the compressor, the water pump, the water cooling unit, the water supercooling unit, and the generator.

[0046] The container 16 may also comprise rechargeable batteries (not shown). The 5 batteries may be charged by using photovoltaic panels, for instance.

[0047] Additionally, the container 16 may comprise an injection system for injecting a snowmaking additive into the water used for snowmaking. The additive may be, for example, DRIFT® or Snomax®.

[0048] Of course, the aforementioned elements can be arranged in one container or 10 in more than one container. Each element may be provided in a single container or only one element or a part of the elements may be provided in a separate container. For example, rechargeable batteries may be arranged in one or more separate container(s).

[0049] In FIGURE 4 a schematic explosion view of a building 5 assembled from modules 4, 4a, 4b of a system 1 for making artificial snow in accordance with at least some 15 embodiments of the present invention is illustrated. The shown building 5 can be assembled from several modules such as a front module 4a, a rear module 4b as well as other modules 4 such as wall modules, roof modules, etc.

[0050] The building 5 is configured to be coupled to a linear guiding (not shown).

For example, some of the modules 4 may each comprise at least one wheel which is 20 configured to be arranged on a rail (not shown) of the linear guiding. Thus, the assembled building 5 can be moved along the linear guiding.

[0051] Further, at least one of the front module 4a and the rear module 4b may be (temporarily) removed from the assembled building 5. Alternatively, at least one of the front module 4a and the rear module 4b may be capable of being at least partially opened, 25 for example by means of at least one sliding door or at least one hinged cover.

Consequently, the building 5 can be moved along the linear guiding such that a pile of artificial snow (not shown) previously produced within the building 5 is located outside of the building 5.

[0052] A benefit of the modularity of the building 5 is that the building 5 can be 30 assembled and disassembled at any desired location. The modules 4, 4a, 4b can be

20185182 PRH 27-02- 2018 transported separately or in groups to the desired location or from one location to another, for example using containers or trucks. In other words, even a quite large building in the form of a hall or hangar can be transported from one location to another due to the modularity of the building 5.
