Definitions
- the invention relates to a device for producing an air curtain in the region of Building opening, in particular a gate or a door, according to the preamble of Claim 1 or 6.
- Air curtains are used to exchange air in the area of building openings to prevent as far as possible. This allows building openings, especially doors and gates in, for example, industrial halls or department stores for unobstructed passage or to be kept open for unobstructed passage, without any appreciable Measures warmer or colder room air escapes to the outside.
- devices are known above or are arranged laterally of a building opening, in particular a gate or a door and create a warm air veil, the warmer through a kind of barrier outlet Room air should prevent to the outside.
- the hot air of the air curtain mixed with the outside air and depending on Wind direction or pressure in the building of the warm air curtain escapes to the outside.
- Such warm air curtains only partially prevent the escape of warmer air outside, so that increased energy losses are the result.
- improved devices which produce a composed of two partial air curtains air curtain, namely a warm air curtain and a curtain, which is not heated, so only Room temperature.
- the Vorschleier should the mixing of the hot air of the Warm air curtain with the outside air and a deflection of the warm air curtain by Wind influences or prevent a higher pressure in the building. It has, however showed that the pre-fog, especially in strong wind load too low penetration depth having. The effect of the pre-curtain thereby increases the device opposite bottom or edge region of the building opening, whereby the Known device only partially escape the warm air after prevented outside.
- the invention is based on the object, a device for Production of an air curtain in the area of building openings, in particular gates and doors, which more effectively prevents the escape of room air.
- An apparatus for achieving this object has the features of claim 1. Characterized in that the device for generating a partial air curtain with an opposite the other partial air curtain is formed higher flow velocity has this partial air curtain, which is preferably the pre-veil over a greater penetration depth. In addition, this is the higher flow rate partial air veils more stable, causing it by wind or increased Pressure in the building is less distracted.
- each partial air curtain can be generated by its own air guiding element.
- the air curtain is formed of two partial air curtains, are accordingly two own Heilleitorgane available.
- the Air guide elements for the production of partial air curtains with different flow velocities formed the air.
- the individual Luftleitorgane the different flow velocities of the individual partial air curtain generated.
- the different Flow velocities of the air of the individual partial air curtain through differently sized air ducting elements, in particular air ducting elements with different large air outlet openings are generated.
- This kind of generating different Flow velocities of the partial air curtain can be particularly easily by a achieve appropriate design of different Gutleitorgane by the one higher flow velocity having partial air curtain through a smaller air outlet opening of the relevant air-conduction organ is achieved by the smaller Air outlet ensures that through this the air in particular of the Vorschleiers, at a higher speed passes through the air in the smaller air outlet opening of the air duct in question is accelerated.
- the air of at least one partial air curtain preferably the pre-curtain
- at least the air outlet opening for the formation of the relevant partial air curtain, in particular curtain in to form variable in size. This can be both continuous (stepless) as also be discontinuous.
- the device is so simple to the given conditions, In particular, different sized openings, adapt by large through the air curtain to "closing" openings the flow velocity
- the Vorschleies is chosen to be larger, to the pre-veil one for large To give openings sufficient penetration depth.
- the Luftleitorgane for division formed of at least one air flow generator originating air flow It is thus possible, in the simplest case with a single air flow generator to form the air flow for both partial air veils.
- the device has over several, for example arranged in series, air flow generator. This but at the same time generate the air flow for all partial air veils, wherein the formation of the individual partial air curtain, in particular the different flow rates same, which serve different air conduction organs.
- the air guide elements thus have several functions: they are used for one for splitting the common air flow generators Air currents and on the other to form the different partial air veils.
- an air guide member has a Bypass on, which serves a part of the air from the total by one or even Divert multiple airflow generators formed common airflow. It is further provided, only one Dunleitorgan, namely the Heilleitorgan for education of a warm air curtain, to assign at least one air heater.
- the air guide to the Formation of the unheated and only room temperature Vorschleiers does not have an air heater. To a heating of the formation of the To avoid pre-veiling air, allows the bypass of the Lucasleitorgans for Formation of the pre-veiling by passing the air of the pre-veil on the air heater to Formation of the warm air curtain.
- Another device for solving the above object wherein it is also be a preferred embodiment of the device described above can, has the features of claim 6.
- everyone is to Forming a partial air curtain serving Heilleitorgan least one own air flow generator assigned. These can be designed or operated differently be, so that partial air veils with different air flow speeds make the air. This does not require the flow velocity a partial air curtain, in particular the Vorschleiers, by a narrowed To form the air outlet opening of the respective Heilleitorgan. Rather, you can the air outlet openings of the Lucasleitorgane the formation of all partial air veils the same size be measured.
- the air outlet openings for Forming different partial air veils of different sizes form, creating a Partial air curtain, in particular the Vor Kunststoffschleier, both by the generation of a higher flow rate through the or each (own) air flow generator as well as a narrowed air outlet opening one opposite the other Partial air curtain, especially warm air curtain, increased flow velocity can receive.
- a Vorschleier in a relatively high flow rate of air are generated.
- the air outlet openings of the Lucasleitorgane side by side to arrange lying to produce adjacent and / or the same directional partial air curtain.
- the partial air curtains form a coherent overall air curtain, the - seen in cross section - has different areas, namely about different temperatures and flow velocities in the individual Has areas, preferably serving as Vorschleierende and a room temperature having partial air veil over a greater flow velocity has as compared to the room temperature warmed warm air curtain with less Flow rate.
- At least the Luftleitorgane in a common Housing housing the device. This makes it possible to have at least one part the Heilleitorgane through the housing, which is designed to form.
- an additional partition is arranged in the housing, which the individual, adjacent Dunleitorgane demarcated and each one Part of every air duct organ.
- the device according to the invention can also serve to form an air curtain, the itself from a pre-veil with room temperature and a cold air veil with a Composed to the room air cooled cold air.
- a device For example, in warm seasons when air conditioners can change the room temperature cooled down from the outside temperature, open building openings left open "close off” against the penetration of warmer outside temperature.
- devices are designed with a designed as a cooling air curtain Partial air curtain also for arrangement in the area of doors and gates of cold storage rooms, Cold stores or the like. It may be appropriate if such Devices of the cold air curtain has a higher flow velocity than the curtain.
- the figures show devices for producing an air curtain in the region of Building opening, namely a door opening 10 in a partially in Fig. 1st illustrated building wall 11, which is an outer wall or a Partition can act.
- the device is horizontally directed above the door opening 10, approximately in the lintel area, arranged.
- the width of the device corresponds approximately to Width of the door opening 10.
- the device is at a room interior facing Inside 12 of the wall 11 attached.
- the device perpendicular to an upright side of the door opening 10 assign, so that the Device over the entire height of the door opening 10 extends, but if necessary also a little shorter or longer.
- the device described below is used to produce a warm air curtain in front of the door opening 10, namely at the inside of the room facing 12 inside the Wand 11.
- a warm air curtain in front of the door opening 10, namely at the inside of the room facing 12 inside the Wand 11.
- Such a device is used in heated buildings or rooms the Outlet warm air through open door openings to prevent the outside. Of the Warm air curtain thus creates a barrier between colder outside air and warmer Indoor air.
- the device shown here has a box-like, elongated housing 13.
- Das preferably made of sheet metal and / or plastic housing 13 has a upper cuboid portion 14, whose length is about the width of the door opening 10th corresponds and an underlying cross-sectional tapered Section 15.
- the tapered portion 15 is about the same length as the cuboid Section 14, thus extending over the entire width of the door opening 10.
- the Section 15 tapers down to the room floor 16.
- Both sections 14 and 15 of the housing 13 are integrally connected.
- the interior 17 of the housing 13 extends over both sections 14 and 15.
- the device shown in Figs. 1 and 2 has three in the longitudinal direction successive air flow generator, in which it is shown in FIG Embodiment by identically designed axial fans 18 is.
- the device But also via other fans, such as centrifugal fans or Diagonal fans, blowers or the like.
- the axial fans 18 are in an upper horizontal top wall 19 of the upper portion 14 of the housing 13th arranged.
- the top wall 19 serves at the same time for holding the axial fans 18.
- the axial fans 18 suck from the ceiling area of a room or a hall with ambient air and blow them into the interior of the Housing 13.
- axial fans 18 in the device shown here are two Heilleitorgane arranged as over the entire length of the housing 13 of the device continuous air ducts 20 and 21 are formed.
- the air ducts 20 and 21 divide one of the axial fans 18 spaced lower part of the Interior 17.
- the cross sections of the air ducts 20 and 21 are of different sizes.
- the relative to the cross section of the device adjacent air ducts 20 and 21 are separated from each other by a longitudinally through the housing 13th extending partition 22.
- a free top edge 23 of the partition ends at a distance below the axial fans 18, so that between the axial fans 18 and the Air guide 20 and 21 a over the entire interior 17 of the housing 13, So the full length and the full width of the same, continuous compensation space 24th arises.
- the generated by the axial fans 18 Air flow which is directed into the interior of the housing 13, on all sides over the entire inner surface of the housing 13 flow and evened from above in both Air ducts 20 and 21 flow. It is so the whole of the axial fans 18th into the housing 13 conveyed air inside the housing 13 divided on the Air ducts 20 and 21.
- An upper portion of the larger shipsleitraums 21 on the of the wall 11 and the Door opening 10 directed away side of the device is associated with an air heater 25.
- This may be a single heat exchanger, for example a Pumped water heat exchanger, act. But it is also conceivable, several Provide heat exchanger, which then, for example, in the longitudinal direction of the device consecutively arranged in the upper region of the air guide 21 in the housing 13 are.
- the axial fans 18 generate a downward direction in the housing 13 Air flow, which is distributed through the serving as an air divider partition 22 through the Air ducts 20 and 21 flows.
- the part of the air flowing through the air guide 21 must forcibly flow past the air heater 25, taking the through the Air duct 21 heats flowing air, for example by an 8 ° to 30 ° over the room temperature lying hot air temperature.
- Air heater 25 When flowing along the air at Air heater 25 serves this as a throttle.
- the result is that through both air ducts 20 and 21 about the same amount of air flow through, although the or Air heater 25 having air guide 21 is greater than that to the door opening 10th pointing air duct 20.
- the latter acts as a bypass, adding to the total amount of through the axial fans 18 in the housing 13 transported air to Heilleitraum 20 diverted air around the or each air heater 25 and around is not heated thereby.
- the room temperature sucked air back to room temperature.
- each Dunleitraum 20 and 21 each have an air outlet opening 26 and 27.
- Each air outlet opening 26 and 27 extends continuously over the entire length of the housing 13 and thus over about the entire width of the Door opening 10.
- the two air outlet openings 26 and 27 are located at the bottom, tapered end of the tapered portion 15 of the housing 13.
- the two Air outlet openings 26 and 27 have a narrow rectangular cross-sectional area.
- the air outlet openings 26 and 27 thus have a slot-like shape.
- the air outlet openings 26 and 27 are in the cross-sectional direction (Fig. 2) of Device next to each other. Separated from each other are the air outlet openings 26 and 27 of the partition 22.
- the two adjacent air outlet openings 26th and 27 are arranged so that they are in the case of the horizontal shown in FIG Arrangement of the device over the door opening 10 in a common, too lying horizontal plane.
- the door opening 10 facing Air outlet opening 26 of Lucasleitraums 20 is narrower than that of the door opening 10th technological air outlet opening 27 from the air guide 21 in the direction outside through the door opening 10 is the wider air outlet opening 27 in front of the narrower air outlet opening 26.
- the air outlet opening 26 about half as wide and thus half the size of the larger air outlet opening 27.
- the invention is not limited thereto. It is crucial that the Air outlet opening 26 under the air duct 20 to form a pre-curtain with Room air is smaller than the preceding air outlet opening 27 for the hot air. It is also conceivable, the width of at least one air outlet opening 26 and / or 27 variable design, both stepless and graded.
- the divided on the air guide 20 and 21 air flows from the air guide 20 and 21 through the air outlet openings 26 and 27 from the housing 13. Because the Air outlet openings 26 and 27 lie in a horizontal plane, arises under the Air outlet openings 26 and 27 a vertically directed air curtain, the width of the Door opening 10 at least corresponds.
- This air curtain is made up of two Partial air curtains, namely (in the direction through the door opening 10 to the outside) one front warm air curtain 28 and a behind it Vorschleier 29. These are dash-dot-lined in Fig. 2 indicated. Through the narrower air outlet opening 26th the Heilleitraums 20 for the room air, the curtain 29 is also narrower than that Warm air curtain 28.
- the narrower air outlet opening 26 under the air duct 20 leads at the outlet of shipsleitraums 20 to a greater narrowing than the air outlet of the shipsleitraums 21.
- the consequence is that from the Heilleitraum 20 through the air outlet opening 26 exiting air flow is accelerated, whereby the curtain 29 a greater flow rate than the hot air curtain 28, which by the larger air outlet opening 27 at the end of Heilleitraums 21 from the housing 19th exit.
- the greater flow velocity of the curtain 29 causes the Pre-veil 29 has a greater penetration.
- the device according to the invention described above can be another Achieve advantage when the axial fans 18 with different speeds operate.
- the Air resistance of the air flowing through the bypass duct 20 serving as a bypass relatively low.
- the Speed of the axial fans 18 increases, so the pressure loss in the narrower Air outlet opening 26 at the bottom of Lucasleitraums 20 for the curtain 29th disproportionately increased, because the air resistance squared with the speed increase increases. It is then more air to the at least one air heater 25th passed through the Lucasleitraum 21 to form the warm air curtain 28.
- the hot air curtain 28 receives more heat energy for more pleasant temperatures inside the room, in particular can contribute to the space heating.
- Fig. 3 shows a device according to a second embodiment of the invention. This is basically constructed like the previously described device (FIGS. 1 and 2), why the same reference numbers are used for the same parts. Only is the lower, tapered portion 15 of the housing 13 is formed asymmetrically. On the wall 11 facing wall portion 31 extends approximately perpendicularly with a small distance to the wall. In contrast, the opposite wall portion 32 of the tapered portion 30 is provided with a relatively oblique course. The result is that the air outlet openings 26 and 27 of the air ducts 20 and 21 itself closer to the inside 12 of the wall 11 are located, namely only slightly are spaced. The distance of the air outlet openings 26 and 27 to the wall 11 is in the device of FIG.
- the air outlet openings 26 and 27 are in one common horizontal plane, which is approximately flush with a top 33 of the door opening 10 completes. But it is also conceivable, the air outlet openings 26 and 27 in one to arrange horizontal plane slightly above or below the top 33 of the Door opening 10 is located.
- the function of the device of Fig. 3 corresponds to that of the device of the figures 1 and 2. Again, passes through the smaller slot-like air outlet opening 26 of the shipsleitraums 20 a pre-veil 29 with a higher flow velocity the flow rate of the hot air curtain 28 from. The curtain 29 and the warm air curtain 28 together form an air curtain directed vertically is and flows with a small distance in front of the door opening 10 along.
- each partial air curtain preferably the Vorschleier and the Warm air curtain, of at least its own air flow generator, for example each axial fan is generated. Consequently, there is no such device Distribution of the jointly generated air flow instead.
- the device has separate Heilleitorgane, which may also be designed as Heilleitschreib. These air ducts However, they are also separated at their upper air inlet sides. It Thus, the compensation space 24 of the two exemplary embodiments described above is missing the device.
- the Air outlet speed from the air outlet openings to form the warm air curtain be changed arbitrarily by increasing or reducing the air flow rate the air flow generator, in particular axial fan.
- the at the before described devices (Fig. 1 to 3) existing constriction of the air outlet opening 26 for forming the pre-veil 29 with respect to the air outlet opening 27 for Formation of the hot air curtain 28 is therefore in this alternative device with Separate air flow generators for each air duct not required. nevertheless can also in the alternative device different sized air outlet openings Use find the flow velocity of the air of the curtain 29 possibly even further compared to the flow rate of the hot air curtain 28 increase.
- the higher flow rate of Vorschleiers 29 against the hot air curtain 28 alone to produce that assigned to the air guide 20 to form the Vorschleiers air flow generator are that produce a larger air flow rate than the air flow generators, the Formation of the hot air curtain 28 find use, so that in the air guide 20 to form the pre-veil 29 already from the air flow generators a higher Flow rate is generated than that in the air guide 21 to form the Warm air curtain 28 is the case.
- the embodiments of the invention described above relate to Apparatus for producing warm air curtains 28 and curtains 29.
- the Invention is also suitable for devices in air-conditioned rooms or Cold stores are used, where outside a higher temperature prevails than in the Inside.
- the device is for forming at least one cold air curtain and a Vorschleiers formed, wherein the air flowing through the Heilleitraum 21 air not heated but cooled.
