Description
- The present invention relates to a device for making artificial snow.
- Devices are already known for manufacturing artificial snow by using water and compressed air, whereby water is atomised in compressed gas and the atomised water is frozen by the cooling effect of the air expansion.
- A compressor is used to supply the compressed gas in the known devices.
- It is known that the compressed gas, which generally consists of air, can have a very high temperature at the outlet of this compressor and can also be moist.
- The known devices thus also contain one or more after-coolers to cool the compressed air, such that the moisture in the compressed air condenses as a result of cooling and can be separated as a condensate using a water separator or similar.
- These after-coolers are generally constructed in the form of air-air regenerative heat exchangers, in which the incoming hot compressed air is cooled by compressed air that has already been cooled.
- The known devices are incorporated in a building of substantial dimensions in which the compressor is housed, and whereby the inlet of the compressor is connected to the outside air to draw in the air to be compressed, while the outlet of the compressor installation is connected to a snow gun to supply the compressed air.
- The pipes provided for the realisation of the abovementioned connections are sizeable in order to emit the heat from the compressed air to the space in the abovementioned building, and to utilise this heat to warm up the cold air drawn in.
- A disadvantage is that this installation is quite large and rather immobile.
- Another disadvantage is that the temperature of the compressed gas at the inlet of the snow cannon is difficult to control.
- A disadvantage attached to this is that the quality of the snow produced depends on the weather conditions, such that the device has rather limited reliability.
- Improved devices are also known, in which there is an additional heat exchanger after the after-cooler for the purpose of controlling the temperature of the outgoing compressed gas.
- A disadvantage is that such a device only enables rudimentary control of the temperature, such that it is not possible to produce high-quality snow under all conditions.
- A further disadvantage is that the heat exchanger cannot prevent moisture condensing in the after-cooler and freezing there.
- A further additional disadvantage is that the known devices use a lot of energy.
- The purpose of the present invention is to provide a solution to one or more of the abovementioned and/or other disadvantages, by providing a device for making artificial snow by means of a snow cannon in which water is atomised by means of compressed air, whereby this device is provided with a compressor for supplying compressed air, which compressor is positioned in a compressor area with an inlet for supplying air from the environment and an outlet to deliver the compressed air to the snow cannon via a pipe, whereby, according to the specific characteristic of the invention, the abovementioned device comprises a heat exchanger with a primary part and a secondary part, whereby the compressed air from the compressor is guided through the primary part, and whereby the abovementioned secondary part makes part of the evaporator of a closed cooling circuit in which a coolant is circulated by means of a compressor element that is driven by a drive, and whereby the abovementioned device includes a controller for controlling the abovementioned cooling circuit in order to obtain the desired temperature or pressure dew point at the outlet of the primary part of the heat exchanger.
- An advantage is that the temperature of the compressed air at the outlet of the primary part of the heat exchanger can be well controlled, such that the snow produced is always of a very good quality and the quality of the snow is not subject to the weather conditions.
- The invention enables the cooling circuit to be controlled accurately so that the desired temperature and/or desired pressure dew point of the compressed air is realised.
- Another advantage is that the device is relatively compact with respect to the known devices.
- An advantage attached to this is that the device is cheaper, not only with regard to the installation cost but also with regard to energy consumption.
- In the most practical embodiment the device can be incorporated into a container and thus be produced as a mobile device.
- An advantage of this is that the container can be easily transported, such that the device can deliver compressed air for the production of snow at different locations, and consequently a relatively large piping system is not needed to connect different snow cannons to one centrally located device for supplying compressed air.
- In a practical embodiment of the invention, the cooling circuit contains a second heat exchanger that forms the condenser of the cooling circuit, and which is located downstream from the compressor element and upstream from the expansion means provided in the cooling circuit.
- In the most practical embodiment the coolant that flows through this second heat exchanger is cooled by a fan. Preferably the abovementioned fan is arranged such that it blows air over the second heat exchanger to the compressor area.
- An advantage of this is that the fan distributes warm air in the compressor area, such that the temperature in the compressor area is above 0° thereby avoiding freezing, and damage due to freezing is thus completely ruled out.
- A further advantage is that no extra large pipes are needed between the outlet of the primary part of the heat exchanger and the inlet of the snow cannon.
- Preferably the temperature of the compressed air at the outlet of the primary part of the heat exchanger is less than 8° Celsius and preferably around 3° Celsius.
- An advantage is that good-quality snowflakes can be produced in this temperature range and the total production time for making the snow is reduced.
- Preferably the compressed air at the outlet of the primary part of the heat exchanger presents a pressure of 8 bar or almost 8 bar.
- Preferably the air is compressed by means of an oil-free compressor such as a water-injected screw compressor.
- An advantage is that the compressed air cannot be contaminated by oil particles, such that this compressed air does not necessarily have to go through one or more filters, which of course has a favourable effect on the cost and size of the device.
- With a water-injected compressor the risk of contaminating the air itself is even completely ruled out.
- With the intention of better showing the characteristics of the invention, a preferred embodiment is described hereinafter by way of an example, without any limiting nature, of a device according to the invention, with reference to the accompanying drawing, which shows a device according to the invention for making artificial snow.
- The device 1 for making artificial snow primarily contains a
compressor area 2 with ahousing 3, which has aninlet 4 for supplying air from the environment and anoutlet 5 for removing the compressed gas such as air. - In a practical embodiment of the invention, the
housing 3 is formed by a container that can be mobile or by a building or similar. - The dimensions of the
housing 3 can, for example, be limited to a floor plan of six metres by six metres, in contrast to existing devices where buildings are used with dimensions that are dozens of metres long and wide. - There is a grid in a wall of the
housing 3 that forms theinlet 4 through which the surrounding air is drawn according to the direction of the arrow L. - In the
housing 3 there is theabovementioned outlet 5 whereby asnow cannon 6 can be supplied with compressed air through apipe 7. - The
snow cannon 6 also has asupply pipe 8 for water, such that water is atomised by the compressed air in a known way at the outlet of thesnow cannon 6, such that snow crystals are formed that disperse from the muzzle of thesnow cannon 6. - For the production of the compressed air, there is a compressor 9 in the
compressor area 2 with an inlet for drawing in air and an outlet 11 for removing the compressed air. - The abovementioned compressor 9 is driven in a known way by means of a
drive 10, such as for example, but not necessarily, an electric motor. - The abovementioned compressor 9 can consist of a single compressor element, as shown in the drawing, but can also be constructed as a multistage compressor, whereby the air is compressed by a number of consecutive compressor elements.
- In a particular embodiment the compressor 9 only contains water-injected compressor elements and intercoolers can also be placed between successive pressure stages. It goes without saying that the invention is not limited to this, as a different type of oil-free compressor, or an oil-injected compressor with appropriate air filtering can be used just as well.
- In a preferred embodiment of the invention, the compressor 9 is set to a maximum service pressure of between 8 bar and 9 bar, and preferably a maximum service pressure of 8.5 bar or almost 8.5 bar.
- According to the invention, there is a
heat exchanger 12 in thecompressor area 2 for the cooling of the compressed air, with a primary part and a secondary part, whereby theinlet 13 of the primary part is connected to the outlet 11 of the compressor 9. - Preferably the
heat exchanger 12 is designed such that the pressure drop of the compressed air that goes through the primary part is less than 0.2 bar, or even better less than 0.1 bar, and preferably even less than 0.05 bar. - It is known that by reducing the temperature, the moisture in the compressed air will condense.
- At the
outlet 14 of the primary part of theheat exchanger 12 there is preferably aliquid separator 15 that can remove the condensed water. - According to the invention, the secondary part of the
abovementioned heat exchanger 12 forms theevaporator 16 of a closedcooling circuit 17 that is filled with a coolant or cooling fluid. - As is known, the coolant is circulated by means of a
compressor element 18 in thecooling circuit 17, and thiscompressor element 18 is driven by adrive 19. - Furthermore, in the closed
cooling circuit 17 between the outlet of thecompressor element 18 and the secondary part of theheat exchanger 12, there is successively acondenser 20 and expansion means, for example in the form of anexpansion valve 21. - In a practical embodiment the
abovementioned condenser 20 is formed by a second heat exchanger and this second heat exchanger is cooled by means of afan 22 that blows air over thecondenser 20 and this air is further blown into thecompressor area 2. - In the most practical embodiment of the invention the speed of the
abovementioned fan 22 can be adjusted in order to control the temperature of the coolant at the outlet of thecondenser 20. To this end the abovementioned fan can, for example, be driven by means of a speed-controlled motor that is connected to a control unit to which measuring means are also connected to measure the abovementioned temperature at the outlet of the condenser, for example in the form of a temperature sensor in the pipe section between theexpansion valve 21 and thecondenser 20. - In a practical embodiment of the invention, the
expansion valve 21 can be constructed as a thermostatic or electronic valve and thisvalve 21 is connected to atemperature sensor 23 that is positioned at theoutlet 14 of the primary circuit. - According to the invention, the device is equipped with a
controller 24 to control the flow of the coolant, and theabovementioned controller 24 ensures the realisation of the desired temperature or pressure dew point at theoutlet 14 of the primary part of theheat exchanger 12. - The
controller 24 can thus control the speed of thedrive 19, whereby a drive is used in the form of a frequency-controlled motor, for example. - The
controller 24 can also be used to control the motor of thefan 22 and/or to control theexpansion valve 21, and if applicable to also drive thedrive 10 of the compressor 9. - It is clear that to control the temperature or pressure dew point, the control of the
drive 10 of the compressor 9 is one of the possibilities, but other arrangements are also possible. - Between the outlet 11 of the compressor 9 and the
inlet 13 of the primary part of theheat exchanger 12, there is preferably an after-cooler 25 and asecond water separator 26. - The method for making artificial snow by means of a device 1 according to the invention is very simple and as follows.
- A gas such as air is drawn into the
compressor area 2 and compressed by the compressor 9. The hot compressed air is first driven through the after-cooler 25 and thesecond water separator 26, after which this already partially cooled gas is guided through the primary part of theheat exchanger 12, such that the compressed air at theoutlet 14 of the primary part has an even lower temperature. - The condensate that is formed in the after-
cooler 25 and theheat exchanger 12 is separated in the respectiveliquid separators snow canon 6 via apipe 7. In thesnow cannon 6 the water will be atomised by the cooled compressed air so that snow crystals are formed. - The cooling of the compressed air in the primary part of the
heat exchanger 12 is realised by driving a coolant through the secondary part of theheat exchanger 12. Preferably this coolant flows in the opposite direction to the air that flows through the primary part of this heat exchanger. - By passing through the secondary part, the abovementioned coolant is heated and then cooled by the
condenser 20, which in this case is placed immediately downstream from thecompressor element 18 in thecooling circuit 17. - The temperature of the coolant will then fall by flowing through the last-mentioned
condenser 20, as thefan 22 blows air over thiscondenser 20. - The air that is blown over the
condenser 20 by thefan 22 is heated. - Because this warm air spreads through the
entire compressor area 2, the temperature in thecompressor area 2 will always stay above freezing point. - The coolant that leaves the
condenser 20 is then guided through theexpansion valve 21, and then again to the inlet of the secondary part of theheat exchanger 12. - For the
heat exchanger 12 and thecooling circuit 17 connected to it with thecontroller 24, a conventional cool dryer can be used if necessary, however the air-air recuperative heat exchanger that is normally used in such a cool dryer is left out. - An advantage is that the device can be easily built from a compressor that is connected to a suitable cool dryer which is available on the market.
- The present invention is by no means limited to the embodiment described as an example and shown in the drawing, but a device 1 according to the invention for making artificial snow can be realised in all kinds of variants, without departing from the scope of the invention.
