Definitions

  • the invention relates to a method for tempering air in a room or the like.
  • the invention has for its object to bring about a particularly effective Jardintemper ist with high comfort in a living zone of the room.
  • room walls or even window areas and / or facade zones for example facade chambers of modern prefabricated facades, are suitable.
  • Air supplied by the air supply of the wall element passes through the heat exchanger of the wall element and reaches the air outlet of the wall element. From there it is brought into the room.
  • the strength of the volume flow of the air supply is preselected. If there is only a small volumetric flow for a small output, then this emerges from the at least one air outlet in the flow form "displacement ventilation" and arrives - in the floor area of the room - to the occupied zone. It is assumed above that by means of the heat exchanger cooling of air takes place, that is, the air emerging from the air outlet is cooler than the surrounding room air.
  • the invention is of course not limited to the cooling case, but can - taking into account changing flow patterns - also be used for the heating case. This applies not only to the method according to the invention, but also to a wall element according to the invention. Since a source ventilation in the occupied zone is perceived as extremely pleasant, there is a high level of comfort. If the power is to be increased, the volume flow of the air supply is increased, with the result that the air exiting from the air outlet, cooled by the heat exchanger air no longer emerges as a source air flow, but as mixed air flow.
  • the mixed air flow is not impulse-poor as the source air flow, but has a pulse according to the power, there is a correspondingly high inductive flow, that is, room air is mixed into the exiting the wall element air, whereby the mixed air flow dissipates energy and the source air flow.
  • room air is mixed into the exiting the wall element air, whereby the mixed air flow dissipates energy and the source air flow.
  • the air exiting the wall element has a high temperature difference with respect to the room air and therefore falls in the region of the wall element downwards, it mixes - as already mentioned - with the warm room air and thereby reduces the air velocity and also its low temperature.
  • it is preferably in the floor area of the room for the source ventilation with only a slight temperature gradient and distributed evenly in the occupied zone.
  • a transition of a source air flow into a mixed air flow and vice versa is provided.
  • the source air flow is present, which then - in its flow form - at higher power passes into a mixed air flow.
  • this mixed air flow is not effected in the occupied zone of the room, but outside of it, so that the mixed air flow in their energy so can reduce that in the occupied zone only calmed and in the low temperature strongly degraded air in the form of source air passes.
  • At least one portion of at least one preferably substantially vertical front wall of the wall element exits a first air flow approximately horizontally and / or by guiding measures in the desired direction.
  • This exiting from the front wall surface of the wall element first air flow preferably has no or only a small change in flow shape as a function of the volume flow, that is, it always occurs as a source air flow or only highly limited in space as mixed air flow into the room and always reaches the residence zone as a source of air.
  • At least one portion of at least one end wall of the wall element exits a second air flow approximately horizontally and / or by guiding measures in the desired direction.
  • this air outlet can be done on both end walls of the wall element.
  • This second air flow is also impulse-poor, regardless of the volume flow of the air supply, that is, even at high power it enters the room as a source ventilation and thus passes to the occupied zone.
  • a mixed air flow can be formed in a spatially very small zone, which then, however, in the residence zone to the source air flow.
  • a third air flow occurs approximately vertically upwards and / or obliquely upwards and / or by guiding measures in the desired one Direction, wherein this third air flow is the one that is subject to the change of the flow shape as a function of the volume flow of the air supply.
  • special air guide elements may be provided in order to swirl the exiting air in such a way that the mixture with the room air in the mixing zone is intensified. This mixing zone may be located above the occupancy zone of persons, so that it is not perceived as disturbing.
  • the wall element can be designed as a decentralized and / or central ventilation device. If the air supply sucks only room air of the room, feeds the heat exchanger and then returns to the room via the at least one air outlet, there is a pure recirculation device. If the fan only supplies fresh air and / or only primary air is used by the air control unit, there is a fresh air device. Of course, there is also the mixed form of both, that is, it is both primary air (fresh air) and secondary air (room air) supplied by the air supply. It is also additionally or alternatively possible that with the supplied air or a portion thereof, room air is induced and that a mixture of supplied air and induced room air is supplied to the heat exchanger. Thus, the air supply is designed as induction device.
  • the air supply air in the lower region of the wall element in particular in the vicinity of the Floor of the room, sucks.
  • the air flow within the wall element thus takes place from bottom to top, wherein a substantial portion of the treated by means of the heat exchanger exits upwardly from the top of the wall element and a smaller portion flows forward from the front wall surface and a further small part of the two end walls.
  • the exit from the end walls can be reduced or prevented by cover, if, for example, in a large office, in opposite to the front wall, a workplace, such as a seat, located and drafts occur.
  • the third airflow emerges as the source ventilation from the top region of the wall element.
  • the third air flow above the wall element preferably up to the ceiling of the room, forms a mixed air flow which is produced by mixing with the room air and arrives as a broad layer in front of the wall element as a source air flow into the occupied zone. This broad layer thus moves in the floor area in the direction of the occupied zone.
  • the third air flow generates a mixed air flow above the wall element below the ceiling of the room, whereby the mixed air flow is caused by strong mixing with the room air and this mixing zone preferably extends substantially below the occupied zone of the room extends the ceiling of the room and the degrading in their kinetic energy mixed air drops as a source of ventilation down into the occupied zone.
  • the first and / or the second air flow enters the room as a source ventilation.
  • the two other air streams or that at least one of them - if the other is not present or covered - always enters the room as a source ventilation, so it is not dependent on what power is driven with the wall element.
  • it is preferably a volume flow change of the air supply means.
  • the heat exchanger is always driven in the cooling mode such that the cooling water used has a temperature of about 16 ° C, so that the power is adjusted / regulated only via the volume flow of the air supply.
  • the speed of the fan determines the power.
  • the user can preselect the speed of the fan, for example, via a tap changer and he is preferably also given the opportunity to change the outlet temperature by influencing the cooling effect of the heat exchanger by appropriate valves, allowing individual adjustment by the user is what ensures a high level of acceptance.
  • the invention further relates to an air-technical wall element which is free-standing and / or constructed as a built-in element and at least one ventilation device, an air supply, at least one heat exchanger and at least one air outlet, so that air coming from the air supply flows through the heat exchanger and then exits the air outlet in particular for use in a process as mentioned above was, wherein the air outlet in the upper region of the wall element is formed such that at least a portion of the air exits vertically upwards and / or obliquely upward.
  • the wall element which can represent, for example, a partition wall in a large office, thermally-treated air ejected in its upper region upwards. The result is that in the occupied zone, even if it is very close to the wall element, no drafts occur because there is always source ventilation.
  • the air outlet is arranged on the end wall of the wall element.
  • the front end wall is the upper narrow surface of the wall element.
  • the heat exchanger is arranged vertically upright or obliquely upright within the wall element. Due to the slight inclination, wedge spaces are formed on both sides of the heat exchanger in the case of a cuboid outer housing of the wall element, one of the wedge spaces forming an air feed space for the air coming from the air feed and the other wedge space forming a collecting space downstream of the heat exchanger, that is to say from the collecting space the air reaches directly to the air outlet or to the several air outlets.
  • the wall element has the air supply in its lower region.
  • the air supply has at least one air conveyor and / or at least one primary air connection. If an air conveyor is used, it can suck in the room air, feed it to the heat exchanger and then into the To reclaim space. This is a circulation circuit. It is of course also possible that the air conveyor only fresh air (primary air) or a mixture of primary air and room air (secondary air) promotes. Additionally or alternatively, it may be provided that a primary air connection is present, to which primary air is supplied, for example from an air center or from a decentralized device. The use of this primary air connection can thus be done alone or in combination with the objects of the above statements.
  • the air conveyor is designed as a fan, in particular as a cross-flow fan.
  • the air supply has an induction device for inducing room air of a room in which the wall element is arranged.
  • the air supply may therefore be additionally or alternatively provided that the air supply has an induction device, that is, with it by supplying primary air and / or Secondary air induced room air, so that the supplied air, together with the sucked by induction air supplied to the heat exchanger and is introduced from there into the room.
  • a further, second air outlet is formed in the region of at least one end wall of the wall element.
  • both end walls of the wall element have such second air outlets.
  • air also exits from the front wall surface of the wall element, wherein the air outlet from the end wall or the end walls and the front wall (and possibly also the rear wall) is lower than the air outlet from the upper region of the wall element, always a pleasant, draft-free atmosphere to create in the immediate vicinity of the wall element.
  • the air outlet located in the upper region of the wall element forms a first air outlet and compared to the second and / or third air outlet - seen from the output side of the heat exchanger - has a lower, preferably substantially lower flow resistance. The result is that a larger volume flow emerges from the first air outlet than from the second and / or third air outlet.
  • the heat exchanger has a length which corresponds to at least half the height of the wall element. Furthermore, it is preferably provided that the wall element is arranged on the floor of the room and maintains a distance to the ceiling of the room, which is preferably less than half, in particular less than one third of the room height.
  • the heat exchanger preferably has a width which corresponds approximately to the width of the wall element or slightly less than the width of the wall element.
  • the heat exchanger is arranged between the first air outlet and the air supply. Accordingly, a very large-scale heat exchanger can be used in the wall element, wherein the heat exchanger preferably in an upright vertical position or upright obliquely inclined position located inside the wall element. It can be realized in this way extremely high cooling performance.
  • the wall element preferably has a partition wall, wherein on both sides of the partition wall in each case an air-technical device can be arranged.
  • Each ventilation device has the features and functions that have already been explained above and will be explained below.
  • the wall element may have at least one sound absorber element.
  • the sound absorber element By means of the sound absorber element very good acoustic properties are created. If the wall element is used, for example, as a freestanding separating element in an open-plan office, then the soundproofing effect of the sound absorber element ensures that noises of the occupied zone do not reach other areas of the room.
  • the wall element thus creates in an individual zone of a room not only individual climatic conditions, but also decisive acoustic advantages.
  • the wall element may - according to a development of the invention - in the zone of its front wall surface and / or in the zone of its rear wall surface have at least in each case at least one sound absorber element.
  • the wall element has a supporting wall, in particular a heavy supporting wall.
  • the weight of the supporting wall ensures that the acoustic attenuation values improve due to the high mass, especially if these are heavy
  • the supporting wall is combined with at least one sound absorbing element.
  • the sound absorber element is attached to the support wall.
  • the support wall is a glass wall or the like.
  • the material glass, ceramic or the like has a high specific gravity and is therefore well suited for good acoustic damping. The same applies to an existing metal support wall with sufficient wall thickness.
  • the support wall is preferably arranged inside the wall element, preferably centrally within the wall element, it forms an inner wall of the wall element.
  • a development of the invention provides that at least one sound-absorbing element is arranged on one side of the supporting wall and at least one ventilation device is arranged on the other side of the supporting wall.
  • the one side of the wall element is therefore provided essentially “acoustically", while the other side of the wall element is equipped essentially “air-technically”.
  • the air conveyor extends on both sides of the support wall. This means that it is not on one side of the support wall, but is designed such that it lies on both sides of the support wall and therefore a very small wall thickness of the wall element can be realized.
  • a development of the invention provides that the support wall has a receiving opening for the air conveyor, so that it comes to rest on both sides of the support wall.
  • This receiving opening breaks through the support wall and allows the air conveyor, such as a fan, to be arranged so that it passes through the receiving opening and therefore lies on both sides of the support wall with corresponding sections.
  • At least one sound-absorbing element as well as an air-technical device are arranged on one side of the supporting wall. It is therefore possible to accommodate both a ventilation device and a sound system on one side of the support wall. In this case, it is also possible to proceed in such a way that there are both at least one sound-absorbing element and one air-conditioning device on both sides of the supporting wall.
