Definitions

the invention relates to a source air passage for ventilation systems, which can be connected at one end to an air duct system via a supply air connection.
the source air passage consists of an outer air-permeable jacket and an inner air-permeable jacket arranged concentrically therein. At least one horizontal diaphragm ring is arranged in the source air passage.
Such air outlets are generally known and are usually installed standing on the floor, so that the supply air from the air outlet to the people within the room to be air conditioned only has to travel a relatively short distance.
This route leads in particular in high and polluted industrial halls through the relatively lightly loaded area near the floor. In this way, the supply air is mixed relatively little with polluted indoor air before it is inhaled by the people. Since there is usually a coupling of heat and pollutant origin in industrial halls, the released pollutants rise in the convective heat flow to the roof of the hall, where they are captured by the exhaust system.
the source air passages In order not to disturb this material flow, the source air passages must supply the supply air to the lounge area at a low air speed and add volume to the rising material flow, so that there is no recirculation of polluted indoor air from higher hall areas into the work or lounge area.
a source air passage of the generic type is known from DE-OS 40 37 287.
the supply air inside the cylindrical, perforated jacket is evenly deflected by horizontal and vertical internals consisting of perforated sheets and fed horizontally to the room to be air-conditioned.
the supply air receives a velocity component directed towards the floor due to the higher density due to the lower temperature after the horizontal outlet from the source air passage. This is reinforced by the Coanda effect of the floor. This causes the supply air layer to constrict with a significant increase in air speed by a factor of 2 to 3. Drafts and increased recirculation of polluted indoor air are the result.
the invention has for its object to design the generic source air passage so that drafts are avoided and that heating of the room to be air-conditioned is possible.
the flow behavior of the supply air emerging from the source air passage can be influenced differently, depending on whether the temperature of the supply air is below or above the temperature of the room air.
the flow cross-section of the tubular guide element can be reduced to zero, which creates an air flow at the outlet from the source air passage, the outlet direction of which is directed downwards and the speed of which increases significantly from top to bottom. This counteracts the rise of the warmer supply air.
the source air passage consists of an outer air-permeable cylindrical jacket 1 and an inner air-permeable cylindrical jacket 2 arranged concentrically therein, both of which are preferably made of a perforated plate.
the source air passage is closed at the top except for the cross section for a supply air connection 3, which can be connected to an air duct network (not shown).
the source air passage is also provided with a closed floor 4 and is on the floor 5 of the hall to be air-conditioned or the other room to be air-conditioned.
a flap 7 is attached in order to change its flow cross-section, with which the tubular guide element 6 can also be opened or closed completely.
the flap 7 is pivotally mounted in the tubular guide element 6 via an axis and can be pivoted mechanically with the aid of a lever or by means of an electrically or pneumatically acting drive 8 acting on the axis.
a swirl vane insert 9 is arranged in the lower part of the tubular guide element 6 in order to generate turbulence.
the swirl vane insert 9 can be vertically displaceable to shift its effective range.
the blades of the swirl blade insert 9 can also be designed to be rotatable in their angular position in order to change the swirl strength.
diaphragm rings 10, 11 are arranged horizontally above the tubular guide element and have a central through opening and an outer ring surface.
the ring surface of the upper diaphragm ring 10 is closed, while that of the lower diaphragm ring 11, which is designed as a pinhole ring, has holes.
a further diaphragm ring 12 is arranged horizontally, which extends over the intermediate space in such a way that it divides it into two annular chambers 13, 14 lying one above the other.
This further aperture ring 12 is perforated in the first exemplary embodiment described here.
the second exemplary embodiment shown in FIGS. 3 to 5 differs from the previously described first exemplary embodiment essentially in that the function of the flap 7 and that of the diaphragm ring 12 is taken over by two horizontal disks 15, 16 arranged one above the other. These divide the annular space between the tubular guide element 6 and the inner jacket 2 into the annular chambers 13 and 14 and the tubular guide element 6 into an upper and a lower tubular guide element section. Openings 17 in the rotatably mounted upper disc 15 correspond to openings 18 in the rigidly arranged disc 16, so that, depending on the rotational position of the disc 15, the openings 17 are more or less aligned with the openings 18 or the openings 17 and 18 with areas of the openings which are not open Disks 16 and 15 are blocked.
the tubular guide element 6 ' is combined from an upper section which is flared upwards and a cylindrical lower section. Disks 15 'and 16' are arranged horizontally between the two sections.
the upper disk 15 'and 16' is not congruent.
the disk 15 ' is rotatably mounted, so that openings 17' in the upper disk 15 'are more or less flush with openings 18' and / or 19 'or are blocked with areas of the disks 15' or 16 'which are free of openings. With fully closed openings 18 'through the segments of the disc 15', the openings 19 'of the disc 16' are fully open.
the tubular guide element 6 ′′ is conically narrowed from bottom to top.
the disks 15 ′′ and 16 ′′ dividing the annular space into the annular chambers 13 and 14 are designed in the form of a gear wheel, so that the tooth-gap-shaped openings 17 ′′ in the rotatably mounted disc 15 ′′ with the tooth-gap-shaped openings 18 ′′ in the rigid disk 16 ′ 'can be aligned more or less or can be blocked by tooth-shaped areas of the disk 16''or15''.
the supply air supplied via the supply air connection 3 enters the interior of the inner casing 2 and exits through the outer casing 1 into the hall to be air-conditioned.
the air flow can be influenced in such a way that the flow-shaped cross-section of the tubular guide element 6, 6 ', 6' 'can be influenced in such a way that the flow patterns shown in FIGS. 12 and 13 are established.
the flow cross-section of the tubular guide element 6 is released so that part of the supply air supplied flows vertically, while the rest of the supply air exits radially through the outer jacket 1 (FIG. 12).
the partial flow flowing through the tubular guide element 6 is deflected at the bottom 4 of the source air passage, enters the lower annular chamber 14 and emerges from the lower part of the outer jacket 1. In this way, the total supply air emerging from the source air passage receives the slightly upward flow direction shown in FIG. Since the supply air is colder than the room air, the supply air sinks into the living area due to the higher density.
the supply air is too low compared to the room air, to avoid a reduction in comfort, it makes sense to overlay the supply air with a swirl of adjustable size in order to adjust the supply air temperature more quickly to the room air temperature.
This swirl is generated with the help of the swirl vane insert 9 arranged in the tubular guide element 6.
the swirl blade insert 9 would undesirably reduce the penetration depth of the supply air. However, this is prevented by closing the tubular guide element 6, as a result of which the swirl is eliminated.
the tubular guide element 6 is blocked so that it is not flowed through. As shown in FIG. 13, an air flow with a strongly downward air outlet direction and an increasing air speed in the direction of the floor 5 is thereby generated on the outside of the source air passage. This counteracts a rapid rise in the warm supply air. The resulting higher room air velocities can be accepted as the warmer supply air is not perceived as a draft during heating and the heating process usually takes place before starting work. If the supply air temperature in summer is higher than the room air temperature, the blow-out characteristic according to FIG. 13 is also selected. In this case, higher air speeds are not harmful at high indoor air temperatures, but are even desirable.
