Description

The invention relates to a method for blowing of supply air into a room according to the generic term of Claim 1.

The method according to the invention serves in particular the blowing of supply air into a room of a ventilation Device or blowing in air into a room by means of a ventilation device of a building.  

The above devices are used in ventilation technology blowing in air into rooms from Buildings where people can stay. The injected supply air serves or participates in the Ventilation of the room. You can also by ent speaking temperature control of the cooling or heating serve the space or participate in it.

Such ventilation devices can in particular Air outlets or induction devices can be in the supply air can be introduced in at least one pressure chamber static constant Exhibits pressure either before Flow into the device about constant static About or in the device constant static pressure regulated or controlled becomes. From at least one pressure chamber of this device the supply air flows into at least one supply air duct one, the adjustment means are assigned to the volume flow adjust the supply air flowing through it to be able to. The adjustment of the entire volume flow the supply air can be in a known manner serve to control the temperature of the subject To control or regulate a room or a room zone and / or around the supplied to the room or the room zone temporal supply air quantity in the desired manner (for example between a minimum value and a Maximum value) depending on the degree of occupancy of the concerned To adjust space.

Such devices cause by the supply air flow Noises from people present in the room  can be perceived as disturbing. The aim is therefore the noise level of the supply air is as low as possible to keep.

If the supply air with variable volume flow enters the device is initiated, i.e. not within the Device generates the variable volume flow of the supply air is caused by a supply air duct outgoing supply air jet due to its door bulenz a sound radiation, which for small outflow Mach numbers proportional to the 8th power of the Jet velocity is. When the volume flow is halved So the sound power is around Factor reduced to 1/256. However, it is often not possible or not with reasonable effort, for each individual device receives the incoming air volume flow independent of the others, the same Devices assigned to this type of space adjust. There are usually several devices in one room arranged, it is often desirable that for each Device individual adjustment or adjustment of the volume flow of the supply air its installation in the room in question or its Ceiling, wall or the like is possible to a individual ventilation or air conditioning of Realize small areas of the room. To this Purpose are devices in the preamble of the claim 1 known type, so in which at least a supply air duct adjustment means for adjusting the volume flow flowing through it are assigned. In the known devices of this type increases however the sound power with increasing throttling of the relevant supply air ducts.  

An induction device is known from DE-OS 28 20 115, at which the variable volume flow of the supply air by throttling or shutting off the inlets of incoming air flowing in from primary air nozzles by means of flaps. This increases with increasing Throttling the sound radiation of the supply air of the individual throttling nozzles.

From DE-PS 20 06 928 is a ceiling air outlet switched off device known. The ceiling air outlet blows the supply air directly into the concerned Building room. The device has a slit-shaped Supply air duct on through through in cross section rectangular filler is formed, their relative to each other facing flat sides parallel to each other run and each of which is for adjustment the volume flow adjustable across the slot is. This supply air outlet also shines with increasing Throttling off an increased sound power.

An air conditioning system for US Pat. No. 3,018,088 a room whose supply air duct is adjustable Inlet is assigned. The air flows through - depending on the position of the insert - a non-adjustable nozzle.

British Patent 15 92 145 goes a volume flow control device for a primary and a secondary air flow from a mixing chamber forth. It is like a water jet pump built nozzle device provided that means by an adjustable in cross section Nozzle flowing primary airflow is caused by negative pressure  radially supplied secondary air. The secondary air flows through an annular slot for this purpose.

The invention has for its object a method according to the preamble of claim 1 create a low-noise throttling of the Supply air volume flow is possible.

This object is claimed by the invention 1 specified method solved.

The invention enables it to be reduced of the volume flow of the supply air at least in a larger adjustment range, if necessary in the entire adjustment range, not to increase the Sound radiation comes. They even succeed Sound radiation with decreasing volume flow of the Supply air preferably over the entire intended To reduce the adjustment range. This is achieved by that the wall boundary layer of the supply air duct flowing through the supply air is free of detachment, the Throttling by adjusting the size of the clear Cross section of the outlet mouth of the supply air duct takes place and the supply air duct is also deformed is that in it the wall boundary layer in operation the supply air remains free of detachment. With increasing Throttling therefore does not increase Sound power, but it can even Reduce sound radiation. When trying by halving the size of the clear cross section the outlet mouth of the supply air duct one Sound level reduction of up to -3 dB achieved. The The degree of turbulence of the inflow is not increased.  In the pressure chamber can also be convenient the wall boundary layer of the supply air must be free of detachment, what by appropriate aerodynamic design is achievable. However, it is an alternative also possible that in the area of the wall of the pressure chamber vertebrae can also be allowed.

The invention can u. a. in ventilation Implement devices in which the supply air duct or ducts or at least one supply air duct directly open into the room to be ventilated, i.e. the supply air outlet or outlet mouths of this Form device, as well as. a. for devices, for those of the supply air free jet or min at least a supply air jet still inside the device from the relevant supply air duct or ducts is blown out, for example in induction devices or the like, the one Have primary air box forming pressure space, in which the supply air is preferably regulated by a Pressostats flows in and on the primary air nozzles are arranged, each of which is a supply air duct forms through which the him from the primary air box incoming air flows out inside the device.

If the ventilation device has several or many All air can preferably have Adjustment means can be assigned to supply air ducts. It however can save costs in many cases or be provided for other reasons, that only one or a few supply air ducts are assigned and the one or more supply air ducts Not.  

In the case of primary air nozzles, the invention is preferred before that all or part of the primary air nozzles completely or at least up to one Longitudinal section of elastomeric outlet opening Material exist and the adjustment of the Cross section of the outlet mouth by elastic Deformation of this outlet mouth made becomes.

It can preferably be provided that the Circular primary air nozzle in unthrottled state Cross-section and their supply air duct itself tapered towards the exit mouth, preferably tapered. The outlet mouth this primary air nozzle can then by their circular shape in oval or elliptical shape by pressing on the outside using a Deform pliers, clamp or the like, whereby this deformation due to the elastomeric material still in the downstream direction of the supply air flow more or less far under gradual Transition to the one that still exists below circular cross section deformed. Hereby can the wall boundary layer of the supply air flow in this supply air duct even with variable throttling until the outlet mouth is shut off stay.

For air outlets where the supply air consists of at least a supply air duct directly in the concerned Emanating space is preferably provided that the outlet mouth of this supply air duct or at least one of these supply air ducts for adjustment  of the volume flow in its clear cross section along with the shape of the supply air duct is adjusted. As mentioned, it is for low noise particularly cheap, all supply air ducts of the relevant ventilation device assign.

The outlet openings can preferably also be provided of the supply air ducts, the adjustment means are assigned, equally strong adjust, because then the noise level of this device with decreasing volume flow in each case particularly becomes low. However, it can also be provided the throttling of the supply air ducts varies make great if this is for any reason is desired, for example desired ones to achieve special room flow conditions.

In many cases, those working according to the invention can ventilation devices each have a single pressure chamber exhibit. But it is also possible to use it to provide several pressure rooms in which different controlled or regulated static pressures can be to the blow-out ratios to influence.  

As mentioned, working according to the invention ventilation devices also as ventilation devices Devices or ventilation devices are referred to. They are devices of the ventilation technology.

As mentioned, can however, the method according to the invention also applies ventilation equipment other than induction devices also find application.

An embodiment of the invention is shown in the drawing and is in following described in more detail. It shows

An induction device in section, Fig. 1,

Fig. 2 is a broken side view of a primary air nozzle,

Fig. 3 is a plan view of two primary air nozzles.

In FIGS. 1-3, an induction device 50 is schematically for air conditioners in section and in some detail provides Darge. This has a primary air box 51 , a heat exchanger 52 , a bypass 53 having no heat exchanger and an air outlet shaft 54 . The primary air box 51 forms a pressure chamber 13 with a constant static pressure of the supply air forming the primary air and has on its top two rows of primary air nozzles 55 made of elastomeric material, for example made of rubber.

The heat exchanger 52 performs cold or warm heat carrier medium for cooling or heating it by flowing, from the room in question by the induction of the primary air consisting of supply air rays drawn in secondary air. Secondary air can also be sucked through the bypass 53 . By adjusting the flap 56 , the heating or cooling capacity of this induction device 50 can be controlled in a known manner.

By means of this induction device 50 , the primary air forming the supply air can be blown out of the primary air nozzles 55 with a variable volume flow even with its reduction in noise as free jets 44 by the primary air nozzles 55 of one row of nozzles by means of two clamping jaws 57, which can be moved in opposite directions to each other, on their top the outlet mouth 21 can be deformably deformed the end regions. The primary air is still mixed in the housing of the induction device 50 with the secondary air and the total supply air thus formed flows out of the air outlet opening 63 'into the building space in question. The primary air here thus forms only a part of the total air blown out into the room through the air outlet opening 63 ', the other part of which is room air. The individual primary air nozzle 55 has a conically tapering supply air duct 17 in the direction of flow of the supply air, which has a trumpet-shaped inlet on the underside and opens out on the upper side towards the air outlet shaft 54 .

Preferably, all of the row in question to primary air nozzles 55 can be synchronously throttled synchronously together at their mouths 21 from the jaw pairs assigned to them, so that the primary air nozzles 55 each of these one primary air row are throttled to the same extent or are simultaneously unthrottled. It can also be seen simultaneously under different throttling of these primary air nozzles 55 before.

The throttling of each primary air nozzle 55 can be continuously adjusted by deforming its circular, maximally large undeformed clear cross section of the outlet mouth 21 by the associated clamping jaw pair 57 , 57 forming the adjusting means to a greater or lesser extent into an elongated, approximately elliptical shape. As a result of the unchanged scope of this outlet mouth 21 , its cross-sectional area for throttling the volume flow of the supply air flowing through it becomes smaller. This elastic deformation of the circumference of the outlet mouth 21 naturally plants in the upstream direction of the supply air duct 17 along the nozzle wall more or less far downward, but only in such a way that the supply air flow in the supply air duct 17 of this primary air nozzle 55 constantly flows with a detachable wall boundary layer . The jaws 57 of each pair of jaws 57 , 57 are shaped as shown in FIG. 3 so that they come into contact with the upper end region of the primary air nozzle 55 and are designed to diverge from one another downward, these jaws 57 thereby also causing the deformation of the primary air nozzle 55 below its upper edge, as shown by a dash-dotted line Darge, can participate, so that they can also influence the de formation of the primary air nozzle 55 below the upper edge, in order to obtain the wall boundary layer of the supply air in the supply air duct 17 in a particularly reliable manner.

The outlet mouth 21 of the primary air nozzle 55 always has the smallest clear cross section of the supply air duct 17 and the cross section of the supply air duct 17 increases from it downwards, so that it does not detach the boundary layer of the supply air in the entire adjustment range of the primary air nozzle 55 Supply air duct 17 comes.

It can be provided that the primary air nozzles 55 can also be shut off by means of the clamping jaws 57 . However, in many cases it can also be provided that the cross sections of the outlet openings 21 of the primary air nozzles 55 of the row in question can only be adjusted up to a predetermined minimum size to ensure a minimum volume flow.

In many cases, it can also be useful to see that all primary air nozzles 55 of this induction device 50 are assigned to clamping jaws 57 for adjusting their outlet openings or only a partial number of the primary air nozzles 55 of one or both rows.

All pairs of jaws 57 , 57 of the relevant primary air nozzle row are mounted on a common cylindrical guide rod 60 by means of bearing bushes 59 arranged axially on them. Furthermore, opposing movement of the two clamping jaws to be parallel to the guide rod 60 57 of each gorge jaw pair 57, 57, a rotatable means of a servomotor or by hand actuating shaft 61 is provided, penetrating the threaded bores of the clamping jaws 57 with alternately arranged left-hand threads 62 and right-hand threads 63 form fit. As a result of this against sensible thread, the jaws 57 of each pair of jaws 57 , 57 can only be adjusted in opposite directions parallel to themselves.

Instead of the clamping jaws 57 , other means for deforming the relevant primary air nozzles 55 can also be provided, for example pliers or the like.

Instead of arranging such primary air nozzles 55 in an induction device, they can also be arranged on other ventilation and air conditioning devices together with a primary air box that feeds them with supply air, for example blowing in the primary air jets between the ribs of a free-standing or covered radiator.

In this embodiment, the pressure chamber 13 is designed so that the wall boundary layer of the supply air is free of detachment at most with the exception of corner eddies at the flow velocities that occur. Furthermore, when adjusting the clear outlet cross-sections 21, the supply air ducts 17 change these supply air ducts in their shapes to a greater or lesser extent, but only in such a way that the wall boundary layers of the supply air flows remain free of detachment in the desired adjustment range.
