Description

The invention relates to a device for air conditioning rooms, an air conditioning arrangement herewith and a method for air conditioning rooms.

The air conditioning of rooms includes influencing various parameters of the room air. The present invention is concerned on the one hand with temperature control, that is to say heating and / or cooling, and on the other hand with air exchange in the form of a desired displacement ventilation by supplying displacement air.

There are already devices for air conditioning known, which are arranged in floor ducts. For example, describes the DE 91 06 753.7 U1 a device for air conditioning rooms with a heating element and a supply air supply element. The device is used for the combined supply of warm air and colder supply air (displacement air) into a room and is installed there in a corner area in the floor. One or two adjacent convectors form the heating element. The air supply member is designed as an elongated shaft and has an air outlet on its upper open side, which is formed by a perforated plate with a large number of large, circular openings and covered with a filter mat. During operation, air is supplied via an air connection and discharged upwards through the air outlet. Room air coming from the room enters an air inlet duct through an air inlet, is heated by the convectors and released at an air outlet of the heating element.

It can be seen as a task to enable room air conditioning in a particularly efficient manner.

The object is achieved by a device for air conditioning rooms according to claim 1, an air conditioning arrangement according to claim 13 and a method for air conditioning rooms according to claim 15. Dependent claims relate to advantageous embodiments of the invention.

The device according to the invention comprises a channel which is provided in particular for arrangement as a floor channel. The direction of extent of the channel is referred to here as the longitudinal direction. A first channel section and a second channel section run parallel to one another in the longitudinal direction.

The first duct section is used to supply displacement air as primary air. For this purpose, at least one source air supply to the first duct section is provided, preferably several, for example in the form of several source air nozzles arranged at a distance over the longitudinal direction. In order to discharge the source air, the first duct section has a first opening section which is oriented towards an opening side of the duct. In the preferred floor mounting of the channel, the opening side is preferably the top. The first opening section is designed to discharge the source air into the room.

The second duct section is designed for temperature control of room air (secondary air) and has a second opening section which is also oriented towards the opening side of the duct. The first and second opening sections are preferably arranged next to one another on the opening side of the channel, particularly preferably directly adjacent to one another.

The second opening section is designed to receive secondary air and to release temperature-controlled secondary air. A temperature control element is arranged in the second duct section to control the temperature of the secondary air. The temperature control can include heating and / or cooling the air. The temperature control element can for example be designed as a heat exchanger, radiator or convector. A fan for conveying the secondary air can also be provided in the second duct section.

In the analysis of known air conditioning devices, the arrangement of both inlets and outlets on the opening side of the duct was recognized as a possible problem within the scope of the invention. In particular, source air emitted at the first opening section can be absorbed again to a considerable extent at the second opening section. However, this is disadvantageous for effective displacement ventilation with the desired formation of a spring air pool in the room. Source air, usually prepared outside air, can preferably be supplied at a temperature slightly (for example 2 to 4 K) below room temperature, with a low air speed being aimed for in order to generate a room climate that is perceived as pleasant. An air supply can preferably be designed in such a way that a pool of swelling air forms in the room. If the source air is heated by heat sources, for example people, electrical devices, etc., there is a buoyancy so that the polluted air rises to the ceiling where it can be sucked off, for example.

On the other hand, temperature control of the room air is also aimed for for room air conditioning, in particular heating the room air during the heating period.

The invention is based on the knowledge that to achieve a desired displacement ventilation with the formation of a source air lake, a separation of the air flows, that is, the secondary air on the one hand and the source air on the other hand, is advantageous. Therefore, it is proposed according to the invention to provide a special outlet shape on the first opening section for discharging the swelling air, which outlet can support a separation of the air flows.

According to the invention, a slot outlet or a plurality of slot outlets is provided on the first opening section, each of which is aligned in the longitudinal direction. Surprisingly, it has been shown that by using one or more slot outlets, an air flow can be achieved which counteracts the suction of the swelling air at the second opening section. At a slot outlet - in contrast to other outlet shapes such as a round outlet, perforated plate, etc. - a flat air flow with a low tendency to turbulence is generated. As will be explained in more detail below, in preferred embodiments in particular a targeted alignment of the flow in a direction pointing away from the second opening section is possible. So the proportion of dispensed source air, which is then taken up again at the second opening section, can be significantly reduced.

A slot outlet is understood to mean any outlet shape which, as an outlet opening, has an elongated shape oriented in the longitudinal direction, that is, the extent of which is greater in the longitudinal direction than in the transverse direction. In the case of the slot outlet, the extent of the outlet opening in the longitudinal direction is preferably more than 3 times the extent in the transverse direction, particularly preferably more than 5 times. Preferably, several slot outlets can be arranged one behind the other in the longitudinal direction in the first opening section, more preferably with a small distance of, for example, less than 50%, particularly preferably less than 20% of the length of the individual slot outlets.

In a particularly preferred embodiment, in addition to the slot outlet or the slot outlets, hole outlets for discharging the displacement air are arranged on the first opening cutout. The hole outlets can be provided, for example, as holes in a wall element, preferably a sheet metal. The perforations can have any shape, for example round or rectangular. For example, one or more rows of perforations aligned in the longitudinal direction can be provided, for example in an equidistant arrangement.

It is further preferred that at least one slot outlet or preferably a row of slot outlets are arranged in the transverse direction of the channel between the hole outlets and the second opening section. The slot outlets and the directed air flow emitted from them thus form a barrier between the flow of source air from the hole outlets and the second opening section of the channel. In some embodiments, additional outlets, for example also slot outlets, can also be provided elsewhere. Advantageously, however, the aim is to provide, if possible, at least one row of slot outlets on an edge of the first opening section which is adjacent to the second opening section.

The slot outlet or the slot outlets preferably have an air guiding element. This is understood to mean that the slot outlet is preferably not just a slot-shaped (elongated) opening in an outlet plane of a first opening section, but rather an air guiding element, which preferably extends at least substantially transversely to the outlet plane, is arranged to guide the dispensed source air . The air guiding element can so the Shape and direct the airflow emitted. For example, a wall element delimiting the slot in the transverse direction and protruding from the slot opening into the interior of the first duct section can serve as an air guiding element. The wall element can have a flat shape, as will be explained below with reference to a preferred embodiment, but it can also preferably be curved and in particular have part-circular sections.

The air guiding element can preferably be designed to guide the dispensed source air in a direction which has a desired angle to the outlet plane. For example, the angle can be 20 to 90 ° to the outlet plane. The angle is preferably less than 90 °, so that the air guiding element leads to guiding the dispensed source air in an oblique direction. For example, directions in the range of up to 60 ° relative to the outlet plane are preferred. The direction is particularly preferably directed away from the second opening section in order to prevent mixing with secondary air sucked in there, but at least to significantly reduce it. For example, the slot outlet with the air guiding element can be designed to emit swelling air at an angle of, for example, 20 to 60 °, preferably 50 ° or less, particularly preferably 40 ° or less.

In a preferred embodiment, at least one of the slot outlets can have an adjustment element for adjusting the slot width and / or outlet device. In this way, a desired air flow can be achieved, in particular also taking into account the conditions of the room, for example the position of obstacles. The adjusting element can preferably be arranged within an air guiding element. Particularly preferably, the adjusting element can be aligned in the longitudinal direction and can be displaced in order to adjust the slot outlet. In particular, the adjustment element can be displaceable in a transverse direction in order to enable adjustment of the slot width and / or the outlet device.

In a particularly preferred embodiment, the adjusting element can have an at least essentially and / or at least partially round cross section, preferably an outer surface. An air guiding element can also have an at least partially and / or at least partially round cross section, preferably an inner surface. In addition to circular cross-sections, this also includes other rounded cross-sections such as oval shapes. Such rounded surfaces favorably result in a low flow resistance.

In a particularly preferred embodiment of an adjustable slot outlet, an adjusting element can be displaced by rotating an adjusting element. The adjustment element can be rotatable about an adjustment axis which is preferably aligned in the longitudinal direction of the slot. The adjustment element can be attached to the adjustment element eccentrically to the adjustment axis, so that it can be displaced by rotating the adjustment axis.

An inlet section for admitting the secondary air and an outlet section for discharging the temperature-controlled secondary air can preferably be arranged on the second opening section. The inlet and outlet sections can preferably be arranged parallel to one another in the longitudinal direction. The inlet section is particularly preferably arranged between the outlet section and the first opening section.

A distribution wall element can be provided in the first duct section between at least one of the displacement air inlets and the first opening section. The distribution wall element can extend in the longitudinal direction. The distribution wall element can be arranged for at least partial separation of a direct connection line between the source air supply and an opening on the second opening section. It can thus contribute to a better air distribution, in particular also to a more uniform distribution in the longitudinal direction. In the case of several displacement air supplies spaced apart in the longitudinal direction, several separate distribution wall elements can be provided, or alternatively a single distribution wall element can also extend over the entire length. The distribution wall element is preferably a flat, planar element, particularly preferably a sheet metal.

In a particularly preferred embodiment, the distribution wall element can be arranged at an angle to the outlet plane of the first opening section, for example. at an angle of 20 to 70 ° to the outlet plane, preferably 30 to 60 °. By arranging the distribution wall element at an angle, a direction of the emitted air flow of the source air can be predetermined or at least supported. For this purpose, the distribution wall element can preferably be inclined in a direction away from the second opening section.

The distribution wall element is particularly preferably arranged in such a way that it leaves a passage area between the source air supply and the first opening section which is significantly reduced compared to the width of the first channel section.

For example, the passage area can correspond to less than 50% of the width of the first channel section, preferably 25% or less. A width of the passage area can be determined, for example, in a plane parallel to the outlet plane of the first opening section.

In preferred embodiments, the temperature control element can be designed as a heat exchanger. For this purpose, it can have at least one line for a temperature control liquid, that is to say a cooling or heating medium. The temperature control element preferably also has a number of slats in order to achieve an increased surface for temperature control of the secondary air flow. The line for heat transfer liquid can be connected to a cooling and / or heating device.

The air conditioning device according to the invention can be arranged in a preferred air conditioning arrangement within a room in a floor duct. The floor channel can particularly preferably be arranged along a wall or a facade element, for example a window. The second channel section is preferably arranged in the direction of the wall or the facade element, that is, between this and the first channel section. More preferably, the second opening section can be arranged flush or with only a small distance to the wall or to the facade element, so that the air flow of the secondary air can be oriented along the wall or the facade element.

The method according to the invention comprises the use of the above-described air conditioning device, source air being supplied for the source air supply and the temperature control element being operated for temperature control of the secondary air. The operation has proven to be very efficient and well suited to the creation of displacement ventilation and the creation of a spring air lake.

One in Fig. 1 and Fig. 2 The illustrated first embodiment of an air conditioning device 10 comprises a duct 12 with a wall formed on three sides made of sheet metal and an upper opening side 14. The duct 12 is divided by a partition 16 in a longitudinal direction L into a first duct section 18 and a second duct section 20 Fig. 1 only a part of the channel 12 is shown, which moreover extends further in the longitudinal direction L.

On the upper side, the channel 12 is covered by a cover grating 28, which is only partially shown here for reasons of better illustration.

The first channel section 18 comprises an interior 22 which is delimited by the wall of the channel 12 and the partition 16. On the opening side 14 of the channel 12, the first channel section 18 has a first opening section 24.

Through a plurality of source air nozzles 26, which are arranged spaced apart in the longitudinal direction L, source air 30 is supplied to the interior 22 of the first duct section 18 and discharged through the first opening section 24 on the top.

A distributor plate 32 serves to better distribute the supplied source air 30 over the length L. The distributor plate 32 covers a direct straight connection between the fresh air supply 26 and the first opening section 24. The lower end of the distributor plate 32 is at a distance D from the partition 16 which is considerably smaller than the entire width B1 of the first channel section 18.

In addition, the distribution plate 32 is arranged obliquely in the interior 22, in the example shown at an angle α of approximately 50 ° to the horizontal.

Various types of outlets are arranged on the first opening section 24 within a horizontal outlet plane. In the first embodiment shown, this comprises a number of slot outlets 32 arranged in a row along the longitudinal direction L and hole outlets 34 arranged in a row in the longitudinal direction L to one another. The slot outlets 32 are on the inside of the first opening section 24, i.e. adjacent to the second Channel section 20 and the hole outlets 34 arranged on the outside.

In the embodiment shown, the hole outlets 34 are round bores in a flat cover plate.

The slot outlets 32 are in Fig. 4, Fig. 5 shown in more detail. As shown there, they comprise a slot-shaped outlet opening 36 which is oriented in the longitudinal direction L. In the example shown, the slot opening 36 is divided by separating disks 38.

The slot opening 36 is bordered by a slot frame 40 from which (see Fig. 5 ) Wall elements 42 extend downward in the direction of the interior 22 of the first channel section 18. The wall elements 42 are rounded and have an inner contour which, in sections, has the shape of a cylinder jacket surface of a circular cylinder. The wall elements 42 define an inner region 44 of the slot outlet 32 with a circular border in cross section and with a first longitudinal center axis L1.

An adjusting element 46 is movably arranged within the inner region 44 of the slot outlet 32. The adjusting element 46 is designed as a circular cylinder with a longitudinal center axis L2 and has a smaller diameter than the inner region 44. The adjusting element 46 is arranged eccentrically within the inner region 44 of the slot outlet 32 so that the longitudinal axes L1 and L2 are spaced from one another.

A round adjusting element 48 is arranged at one end of the slot outlet 32. The adjusting element 48, adjusting element 46 and the separating disks 38 can preferably be formed in one piece. By rotating the unit formed from these elements within the inner area 44 of the slot outlet 32 about the axis L1, the adjustment element 46 can be displaced so that different parts of the inner area 44 are covered depending on the position specified by the rotation of the adjustment element 48. So, on the one hand, an effective one that is available for the flow through Slot width can be adjusted. On the other hand, it is also possible to set the direction of the displacement air 30 flowing out at the slot outlet 32.

For example, by displacing the adjusting element 46 in front of the slot opening 36, a clear narrowing of the outlet can be achieved. By shifting it to the side, for example in Fig. 5 As shown, a delivery direction of the displacement air 30 which is inclined to the vertical can be specified. Due to the partially round shape of the wall elements 42, as in FIG Fig. 5 An oblique deflection of the air flow 30 represented schematically by arrows. The wall elements 42 thus serve as air guiding elements.

As in Fig. 2 As is shown schematically, the source air flow 30 that is emitted at the first opening section 24 is composed of a first portion that is emitted through the slot outlets 32 and a second portion that flows out through the hole outlets 34.

The first portion of the source air 30 flowing through the slot outlets 32 is a largely flat, directed flow with low turbulence due to the slot shape. As a result of the guidance described above, the first portion of the displacement air exits in a targeted manner at an oblique angle to the outlet plane, directed away from the second duct section 20.

The second portion of the displacement air 30 that is discharged through the hole outlets 34 is less aligned and laminar in comparison with the first portion. However, it still has a predominantly outflow direction which is oriented obliquely to the outlet plane and which is influenced by the oblique position of the partition plate 32.

Overall, there is an air flow of the displacement air in an oblique direction, which is oriented towards the top right in the drawings. The directed first portion of the displacement air covers the second portion and acts as a separating jet with respect to the second channel section 20.

The second duct section 20 comprises an interior space 48 in which a convector 50 is arranged as a temperature control element. The convector 50 comprises a plurality of upright sheet metal fins (not shown in detail) and a temperature control medium line (not shown) which is connected to a heating and / or cooling device. The convector 50 is preferably used to heat room air and is operated with a heating medium. Then as in Fig. 2 A convection is shown schematically at a second opening section 54 on the upper side of the duct 12, in which secondary air 56 is sucked in through a receiving section 58, heated by the convector 50 and released as heated secondary air 60 through an outlet section 62.

The air conditioning device 10 can, as in FIG Fig. 3 shown schematically for air conditioning a room 64 as a floor duct along a facade element 66, for example a wall or a window. In the preferred arrangement shown, the second channel section 20 is arranged in the direction of the facade element 66 and the first channel section 18 is arranged in the direction of the center of the room.

Supplied source air 30 (solid lines) is released through the first opening section 24 into the interior of the space 64, where it forms a source air pool 68.

Room air is sucked in as secondary air 56 (dash-dotted lines) at the second opening section 54, heated by the convector 50 and released again at the second opening section 54 as heated secondary air 60 (dash-double-dotted line). Due to the arrangement of the outlet section of the second opening section 54 close to the facade element 66, the air flow of the heated secondary air 60 is oriented towards the surface (Coanda effect).

Due to the special air flow that is generated due to the arrangement of the outlets 32, 34 on the first opening section 24, an immediate suction of supplied source air 30 into the adjacent second opening section 54 is largely avoided. Displacement air, which is sucked in at the second opening section 54, rises to the ceiling after being heated by the convector 50 and hardly contributes to displacement ventilation in the room. This is avoided on the one hand by the inclined discharge direction of the source air flow 30 directed away from the second channel section 20 and on the other hand by the uniform, low-turbulence flow course that is achieved by means of the slot outlets 32.

As a result, the source air flow is a gentle air flow that flows in a directed manner over the floor into the room and contributes in the desired manner to the formation of displacement ventilation with the formation of the source air lake 68.

The operation is preferably carried out in such a way that source air 30 is supplied at a temperature of 2 to 4 K below room air temperature. The supply of the source air takes place in such a way that an average air speed of the source air flow 30 in the room of less than 0.3 m / s, preferably of less than 0.2 m / s results.

It will be apparent to a person skilled in the art that the device, arrangement and mode of operation shown are to be understood as merely exemplary and not restrictive and that the invention can also be implemented in other ways. For example, the type, number and arrangement of the outlets, in particular in the first opening section 24, can be changed. Fig. 6 , 7th and 8th each show alternative embodiments with a different number of hole outlets 34 and / or slot outlets 32.

Further changes are conceivable. For example, the arrangements of receiving section 58 and outlet section 62 can be exchanged. Secondary air can also be cooled instead of heating. Furthermore, it is also possible to arrange a device for generating an air flow, for example a blower, ventilator, etc., in the second duct section 20 in order to support or ensure the suction and / or discharge of secondary air.

In addition, control elements can be provided, for example for the supplied source air, e.g. B. as sliding elements in the displacement air nozzle 26, in order to enable an air-technical comparison of a plurality of floor convectors with one another. <b> List of reference symbols: </b> 10 Air conditioning device 12 channel B1 Width (from 18) 14th Opening side D.
