DE2822062A1 - Space ventilation unit - has series of noise damping components in conduits joined to common filter chamber - Google Patents

Abstract

The space ventilation unit has two openings or sets of openings, each of which can act as an outlet instead of inlet, being mounted on the inside of a house outer wall. Each of the inner conduits ending at the openings (1, 23a, 23b) has a special succession of noice-dampening componets. The conduits join each other in a non-transparent collapsible chamber containing filters for dust, other suspended matter and insects. This chamber also forms the preliminary stage of a succession of noice-dampening units in the conduits.

description

It is the task of the construction described below and its various extensions or integration in heating devices, the fresh air throughput within the trees of houses and mobile facilities without particularly complex energy supplies and without significant losses of heat through the ejection of used room air to a constant To transform process, which at the same time solves the multitude of secondary problems, which are given depending on the purpose of the room, · To this only to name a few examples: a bedroom needs a certain constant Fresh air flows through the air without sound or light coming through the openings and insects as well as debris, such as dust in particular, penetrate

neii; room heating is usually content with internal convection, So the air flow circulation, which through the different Luftdich te is caused as a result of the temperature differences; if the heat source is in the seam, it causes oxygen consumption in the room air, if it is outside of the room, as with central heating systems and so-called external wall oil heating systems, annoying dry air is associated with various health side effects; the modern design creates with well-fitting aluminum frames More and more airtight rooms, which differs from the wooden frame that never closes tightly or that loses its density over time With a sash division of the window, a constant, moderate but regulated, i.e. imperceptible fresh air supply and room air discharge as a necessity makes conscious, but at the same time sets the task of doing this with the least possible heat loss. So it goes in Relation to the simplest device form for the technical task of creating a kind of "breathing equilibrium" between space and free atmosphere, With regard to device expansions, it is a question of preparing the space heating devices of the known type with such an addition of fresh air to ensure that neither oxygen consumption nor loss of air humidity occurs in an inadmissible manner.

The concept of solving the problem described is not based on creating a device that obtains the energy required for its function from the power grid or through direct consumption of fuel, but rather on the abundance of obvious or "hidden" flow processes To be used especially in houses as a driving medium, especially for the fresh air delivery service. There is already such a thing, e.g. in the ventilation systems of bathrooms and toilets, in which an air inlet grille, usually let into the lower zone of the door, allows air to flow out through an opening near the ceiling, which leads to a so-called Air shaft leads to allow; that works quite well, only it's not soundproof. The same applies to the usual systems in which the exhaust air is produced by a whirring fan.

Figure 1 shows an example of the group of measures in which the connection to heating processes is taken, a fresh air intake device that can be positioned above or below a central heating element Let's assume that it is underneath a central heating unit is located. It is then completely within an ascending cold air thermal (indicated by the large arrows), the ν

also enters at the openings 23b and exits again at the openings 23a, here however with fresh air (indicated by the white arrows. The fresh air is added by ejection from the room 21: the fresh air enters from a house wall opening with line 1, passes into a capsule body 13 · in which the cleaning of sound, suspended matter and dust takes place in this air. In addition, it is opaque. The quantity of air throughput is greater if the device is installed above the central heating body, because the greater heat absorption and storage of the casing body 2k _t especially if it is made of ceramic, it significantly increases the air throughput through the space 22. In addition, every ejector depends on the line being ejected to be designed with as little resistance as possible: the extraordinary effectiveness of the in the capsule body 13 built-in acoustic see attenuation elements allow for this low The greatest possible cable cross-section must be provided for the greatest possible cable resistance.

FIG. 2 shows the same system without being integrated into a heating system. In contrast to Figure 1, this is a section through the

Kfcpseiraum 13 made. It shows a group of fine ceramic ducts that serve as a sound-absorbing element that filters out penetrants. In addition to the bowl-like outer cover 2k , ceramic decorative plates of a verfrchieii.-nfiter type are possible. As movement elements for the air currents passing through, all flow processes as they occur outside of the house can be used, such as the otrömungsgehügel existing in every house from the interior to the outside, various interior spaces with one another and between the positions of various exterior walls. House (light side / shadow side, constant wind flow zones, various types of landscape conditions): the installation of at least two such devices on usually completely opposite house sides, e.g. in a hallway, activates these flow elements. But even the installation of only one device of this type in a closed room activates the air balance through the size of the flow cross-sections, which is portable due to the strong sound-absorbing effect. The fact that this does not result in an unacceptable loss of heat, as in the case of a hole of the same size in the wall, can be ensured by the measure of claim 8: by the hollow profile body made of aluminum the . ' The storage heat of the massive parts of the house accepts, if it is laid in sufficient length in the ceilings, etc., even with a single device per tree, only tempered fresh air gets from the outside to the inside due to the long dwell times. Constructive solutions on the outside opening (26, FIGS. 1 and 2) allow air currents that act in the open atmosphere, whether pressure or suction, to act as constant air introduction or air extraction processes, imperceptibly for the residents, and through the combination with The air quality can be subject to permanent automatic regulation in the case of constantly evacuating positions on the more distant sides of the house. It is not the task of this description to provide the necessary details for this in detail. The claims set out in detail which objective constructive guiding principles are relevant for this.

The main claim is based on the fact that two strands of wire meet in a.ii capsule space (13), the necessary filter body and comprises the acoustic pre-stages. Every wire harness owns a separate sequence of sound-absorbing stages. Through the through achievable attenuation, the large cross-sections are possible, on which the throughput performance of such a device depends.
