Air distributor (100) for a stable building (1000), with an air duct (101), an outlet gap (106) for air and a baffle plate (110), characterized by two air guide devices (120) which are arranged to flow out air on two Restrict main flow directions (HR).

Description

The invention relates to an air distributor for a stable building, in particular for a stable building for keeping livestock and a stable building.

Air distributors are used to circulate the air in stable buildings and/or to distribute fresh air or outside air in stable buildings. Particularly in livestock farming, efficient and effective air distribution is important for animal welfare and emissions management. Existing air distributors are described in DE202006015130U1 , DE202011001768U1 , DK168774B1 or GB1216703A .

However, existing air distributors often distribute air inadequately or with little efficiency. Furthermore, further improvements with regard to air distribution are desirable.

It is therefore an object of the present invention to provide an air distributor for a stable building and a stable building which reduces or eliminates the disadvantages mentioned. It is a further object of the present invention to provide an improved air distributor for a stable building and an improved stable building. In particular, it is an object of the present invention to provide an air distributor for a stable building and a stable building, which enable better, in particular more efficient and effective air distribution in a stable building for livestock farming.

This object is achieved according to the invention by an air distributor for a stable building, in particular for a stable building for keeping livestock, with an air duct, an outlet gap for air and a baffle plate, characterized by two air guide devices which are arranged to limit the outflow of air to two main flow directions. The air distributor preferably guides the air through a vertical air duct onto a baffle plate, which is preferably horizontal in the operating state, which deflects the air in a preferably horizontal direction and allows it to exit through an outlet gap, preferably at an angle of 360 degrees. The air distributor also has two air guide devices which are arranged to limit the emerging air to two main flow directions.

The air duct is preferably arranged vertically in the operating state and/or in particular has a longitudinal axis, which is preferably aligned essentially vertically in the operating state. The air duct can be used in particular to suck in outside air, in particular through a supply air opening. The outside air can also be referred to as fresh air. The air distributor and/or the air duct can also have a heat exchanger in order to warm up outside air that has been sucked in (particularly in the cold season).

The air duct can optionally have a circulating air supply gap and/or a circulating air opening, a fan and/or a mixing chamber for mixing outside air and/or circulating air to form mixed air.

The air distributor can also have a circulating air supply gap and/or a circulating air opening for sucking in circulating air. Recirculated air is, in particular, air from inside the stable building. In particular, the mostly warm circulating air can be used to heat the mostly cold outside air.

The air duct may contain a fan to keep the air flowing in the desired direction. The air can also be moved by other methods, for example by creating a negative pressure in the stable building.

The fan of the air distributor is preferably designed to suck in outside air through the air duct and/or to suck in circulating air through the circulating air supply gap and/or a circulating air opening and/or to allow air to flow out of the outlet gap. The fan thus preferably ensures an air flow through the air distributor, namely from the air duct, in particular its air opening, and/or from the circulating air supply gap and/or the circulating air opening to the outlet gap.

Furthermore, a baffle plate is provided, which preferably serves to deflect the air and/or preferably limits the outlet gap. The baffle plate preferably diverts the air flow from a flow direction that is preferably essentially vertical in the operating state into a preferably essentially horizontal outflow direction. A substantially horizontal outflow direction can include a range of at least +/- 3° and/or a maximum of +/- 65° to a horizontal plane, i.e. air flowing out of the outlet gap can also preferably be 3 to 65° upwards from the horizontal and /or flow downwards.

The air distributor also has two air guiding devices, which are preferably arranged in the outlet gap and/or on and/or on the baffle plate. The two air guide devices serve to limit the outflow of air, in particular from the outlet gap, to two main flow directions.

The solution described here is based, among other things, on the knowledge that, unlike an outflow of air, essentially via the entire scope of the air distributor, as provided in the prior art, a restriction of the outflow to two main flow directions unexpectedly brings with it various advantages in terms of the efficiency and effectiveness of the air distribution in the stable building.

Existing solutions flow the air out essentially over the entire circumference or over essentially 360°. Guide elements are sometimes used to achieve a particularly even air distribution or to optimize the air distribution in stable buildings with an essentially rectangular floor plan. However, there is no provision for a restriction to two main flow directions.

One of the findings of the solution described here is that when air flows out essentially over the entire circumference of the air distributor, as is provided in the prior art, eddy currents and / or a so-called air roller can form, which has a disadvantageous effect on the affect flow characteristics. This can negatively influence the range and/or the flow speed. Existing solutions for air distributors usually lead the air into the stable from above onto a baffle plate that directs the air flow horizontally in all directions, and blow the air close to the stable ceiling horizontally at an angle of 360°, i.e. along the circumference of the air distributor in all directions, into the stable. The solution presented here is based, among other things, on the knowledge that an air roller is formed around the air distributor between the blown-in air and the stable ceiling, which pulls the blown-in air up to the ceiling and removes a lot of energy from the air flow. The speed and range of the airflow are reduced, thereby reducing the effectiveness of the air distributor.

The solution proposed here, on the other hand, envisages directing the air flow through the two air guide devices only in two main flow directions, thereby preventing or reducing the formation of eddy currents and/or an air roller and thus increasing the speed and range of the air flow.

Another advantage of the solution described here is that predominantly circulating air, which has already passed through a large part of the stable building, is again captured by the air flow, which results in particularly good mixing of the air in the stable building.

The solution described here with increased flow speed and air mixing has the further advantage that a better removal of emission gases from livestock and their excrement can be achieved in the area where livestock are kept, which has a positive effect on both animal welfare and emissions management.

References in this description to the two main flow directions and/or the two air guiding devices, in particular to each of the two main flow directions and/or each of the two air guiding devices, mean in particular that the features described in each case can apply to both main flow directions or both air guiding devices. However, it is also possible that the two main flow directions or the two air guiding devices are each designed differently and a feature described in each case only applies to one of the two main flow directions or one of the two air guiding devices. The same applies to the two blocking directions mentioned later.

According to a preferred embodiment, it is provided that each of the two main flow directions is aligned essentially horizontally in the operating state. A substantially horizontal main flow direction can include a range of at least +/- 3° and/or a maximum of +/- 65° to a horizontal plane, i.e. air flowing out of the outlet gap can also preferably be 3 to 65° upwards from the horizontal and /or flow downwards.

A further preferred development is characterized in that the two main flow directions are aligned opposite one another. The two main flow directions are therefore preferably opposite to one another. This results in a particularly advantageous flow behavior, through which the above-mentioned advantages are particularly noticeable.

In a preferred embodiment it is further provided that each of the two main flow directions has a horizontal flow angle of at least 45° and/or a maximum of 135° in a plane orthogonal to a longitudinal axis of the air duct. These horizontal flow angle ranges cause a particularly advantageous flow behavior, through which the advantages mentioned above are particularly noticeable.

A further preferred development is characterized by two blocking directions, with the two air guide devices blocking the outflow of air in the two blocking directions. The blocking directions are preferably flow directions in which there is essentially no air flows out of the air distributor, which is prevented in particular by the two air guide devices. These blocking directions preferably contribute to the separation of the two main flow directions from one another and thus reinforce the advantages mentioned at the beginning.

Furthermore, it is preferably provided that the two blocking directions are aligned opposite one another. The two blocking directions are therefore preferably opposite to one another. This results in a particularly advantageous flow behavior, through which the above-mentioned advantages are particularly noticeable.

It is further preferred that each of the two blocking directions has a blocking angle of at least 45° and/or a maximum of 135° in a plane orthogonal to a longitudinal axis of the air duct. These blockage angle ranges cause a particularly advantageous flow behavior, through which the above-mentioned advantages are particularly noticeable.

According to a preferred embodiment, it is provided that the main flow directions and blocking directions are arranged alternately in a plane orthogonal to a longitudinal axis of the air duct. This causes a particularly good separation of the two main flow directions from one another and also leads to a particularly advantageous flow behavior, through which the above-mentioned advantages are particularly noticeable.

In a further preferred embodiment it is provided that each of the two air guide devices is designed as a V-shaped guide element. Each of the two air guide devices can preferably have two essentially plate-shaped guide elements, which preferably have a main extension in a vertical plane in the operating state, in order in particular to limit outflow in the lateral direction. Each of the two air guide devices can also preferably have air directing fins, which preferably connect to the essentially plate-shaped guide elements and are preferably aligned essentially horizontally in the operating state. These configurations are particularly simple and inexpensive to implement while at the same time being highly effective.

It is further preferred that each of the two air guide devices is arranged in the outlet gap. It is particularly preferred that each of the two air guiding devices is arranged on the baffle plate. Each of the two air guide devices can also be arranged on a central element of the air distributor. These configurations are particularly simple and inexpensive to implement while at the same time being highly effective.

According to a further preferred embodiment, it is provided that each of the two main flow directions has a vertical flow angle of at least 3° and/or a maximum of 65° in a vertical plane enclosing a longitudinal axis of the air duct. These vertical flow angle ranges cause a particularly advantageous flow behavior, through which the above-mentioned advantages become particularly apparent.

Overall, a flow cone preferably results in each of the two main flow directions, which has an extension in the vertical direction and in the horizontal direction with the horizontal and vertical flow angles described here.

Further advantageous embodiment variants of the previously described air distributor result from combining individual, several or all of the preferred features described here.

According to a further aspect of the invention, the aforementioned object is achieved by a stable building with at least one previously described air distributor. A stable building preferably has several air distributors, which are preferably designed in the same way. In particular, the properties and advantages of an air distributor described here also apply to individual, several or all of the other air distributors in stable buildings with several air distributors.

A preferred development of the stable building is characterized in that the stable building has a longitudinal extent and a transverse extent, the longitudinal extent being many times larger than the transverse extent, and wherein the at least one air distributor is arranged such that the main flow directions are directed parallel to the transverse extent and /or the blocking directions are directed parallel to the longitudinal extent.

Stable buildings often have a substantially rectangular floor plan with short gable walls along the transverse extent and longer stable walls along the longitudinal extent. A roof ridge of the stable building often runs parallel to the stable walls and the longitudinal extension.

A further preferred development of the stable building is characterized in that the at least one air distributor is arranged so that the main flow directions are in the direction opposite stable walls are directed and/or the blocking directions are directed towards opposite gable walls.

The arrangement of the air distributors in such a way that the main flow directions are directed towards the stable walls and thus the air guide devices allow the air to flow out towards the stable walls is particularly preferred for high efficiency and effectiveness of the air distribution and in particular to increase the speed and range of the air flow .

According to a further aspect of the invention, the aforementioned object is achieved by a method for distributing air in a stable building, comprising sucking in air, in particular outside air and/or recirculated air, preferably mixing the sucked in outside air and/or recirculated air to form air, redirecting the air from a preferably vertical to a preferably horizontal direction, preferably through a baffle plate, and the air flowing out limited to two main flow directions.

A preferred development of the method is characterized in that the outflow of air is restricted to two main flow directions by two air guide devices.

A further preferred development of the method is characterized in that the air flows out towards opposite stable walls and/or parallel to a transverse extension of the stable building.

Regarding the advantages, preferred embodiments and details of each aspect and its preferred embodiments, reference is also made to the corresponding advantages, preferred embodiments and details described with respect to the respective other aspects.

In the figures, identical or essentially functionally identical elements are provided with the same reference numerals. General descriptions generally refer to all embodiments unless differences are explicitly stated.

1 shows a stable building 1000 for keeping livestock with an air distributor 100. The stable building 1000 has a longitudinal extension LE and a transverse extension QE. The longitudinal extent LE is many times larger than the transverse extent QE, where in 1 only part of the entire stable building 1000 is shown. The stable building 1000 has a substantially rectangular floor plan with short gable walls 3 along the transverse extension QE and longer stable walls 1 along the longitudinal extension LE. The roof ridge 2 of the stable building 1000 runs parallel to the stable walls 1 and the longitudinal extension LE.

In a stable building 1000, several air distributors 100 are usually arranged, with in 1 only one air distributor 100 is shown. The properties of the air distributor 100 described here preferably also apply to stable buildings 1000 with several air distributors 100.

The air distributor 100 is equipped with an air duct 101, which can contain a circulating air opening, a fan, a mixing chamber for mixing outside air and / or circulating air to mixed air, an outlet gap 106 for air and a baffle plate 110 for redirecting air. Furthermore, air distributor 100 has two air guide devices 120 in the outlet gap 106, which are arranged to allow air to flow out of the outlet gap 106 to limit HR to two main flow directions.

The longitudinal axis LA of the air duct 101 is essentially vertically aligned in the operating state. The air duct 101 serves to supply air to the baffle plate 110 and outlet gap 106.

The exit gap 106 is limited by the baffle plate 110. The baffle plate 110 redirects the air flow from a flow direction that is preferably essentially vertical in the operating state to a preferably essentially horizontal outflow direction. Two air guide devices 120 are also arranged on the baffle plate 110. These serve to limit the outflow of air from the outlet gap 106 to two main flow directions HR. This can advantageously prevent or reduce the formation of eddy currents and/or an air roller and thus increase the speed and range of the air flow.

In the operating state, the two main flow directions HR are essentially horizontal and aligned opposite one another and opposite to one another. Furthermore, each of the two main flow directions HR has a horizontal flow angle α ₁ of at least 45° and/or a maximum of 135° in a plane HE orthogonal to a longitudinal axis LA of the air duct 101.

Furthermore, the two air guide devices 120 block the outflow of air in two blocking directions BR. The two blocking directions BR are opposite one another and aligned in opposite directions to one another. The two blocking directions BR have a blocking angle β ₁ of at least 45° and/or a maximum of 135° in a plane HE orthogonal to a longitudinal axis LA of the air duct 101. In the blocking directions BR, essentially no air flows out of the air distributor 100, which is prevented by the two air guide devices 120. These blocking directions BR thus contribute to the separation of the two main flow directions HR from each other.

In a plane HE orthogonal to the longitudinal axis LA of the air duct 101, the main flow directions HR and blocking directions BR are arranged alternately. This results in a particularly good separation of the two main flow directions HR from each other.

The two air guide devices 120 are designed as a V-shaped guide element and have two essentially plate-shaped guide elements 121 with a main extension in a vertical plane in the operating state. This limits outflow in a lateral direction. The two air guiding devices 120 also have air directing fins 122, which adjoin the essentially plate-shaped guide elements 121 and are aligned essentially horizontally in the operating state.

Like in particular 4 can be seen, the two main flow directions HR have a vertical flow angle α ₂ of at least 3° and/or a maximum of 65° in a vertical plane VE enclosing a longitudinal axis LA of the air duct 101.

Overall, this results in a flow cone in each of the two main flow directions HR, which has an expansion in the vertical direction and in the horizontal direction with the horizontal and vertical flow angles described here.

The air distributor 100 is arranged in the stable building 1000 so that the main flow directions HR are directed parallel to the transverse extension QE and the blocking directions BR are directed parallel to the longitudinal extension LE. The air distributor 100 is arranged in the stable building 1000 so that the main flow directions HR are directed towards opposite stable walls 1 and the blocking directions BR are directed towards opposite gable walls 3.

The arrangement of air distributors 100 is therefore such that the main flow directions HR are directed in the direction of the stable walls 1 and thus the air guide device 120 allows the air to flow out in the direction of the stable walls 1. This is particularly preferred for high efficiency and effectiveness of air distribution and in particular to increase the speed and range of the air flow.

In 5 a method 200 for distributing air in a stable building 1000 is shown schematically. In a step 201, air is sucked in, in particular outside air and/or recirculated air. In a further optional step 202, the sucked in outside air and/or recirculated air is preferably mixed to form air, and in step 203 the air is diverted through the baffle plate 110. In step 204, the outflow of air is limited to two main flow directions HR.

The sequence of steps given here is preferred, but can also take place differently if practical and sensible. In particular, individual, several or all of the steps can run parallel to one another and/or at least partially simultaneously and/or overlapping in time.
