Definitions

  • the application relates to a system for ventilating a building.
  • regulated ventilation systems are increasingly common. These allow air exchange at a sufficient rate without, however, exchanging unnecessary amounts of air. This avoids an unnecessarily increased heating energy requirement.
  • the heat contained in the exhaust air is at least partially transmitted to the supply air in controlled ventilation, thereby further reducing the
  • Heating energy demand is enabled. If the conditions require cooling of the building, analogous considerations apply.
  • Supply unit is an air conveyor, usually a larger fan, assigned.
  • air conveyor usually a larger fan
  • the fan provides a certain pressure and depending on the position of the individual valves, the air flow is regulated in the different areas of the building. It can be seen that this sometimes requires an increased amount of energy to transport the air.
  • DE 1 0 2007 049 333 A1 discloses an air conditioning system, in particular for ships.
  • This comprises a central air supply device, which comprises a central fan, and a main channel connected thereto with a plurality of branch channels.
  • This air treatment in different rooms, especially ship cabins is achieved.
  • Each branch channel is provided with a supply air unit. A perceived as unpleasant noise should be avoided by each
  • Supply air unit is provided with a fan that just so much differential pressure builds up that a flow of air into the respective room with little or no
  • a plurality of air conveying devices is present, wherein the individual air conveying devices for conveying the supply air are arranged in different areas of the building and / or for removing the exhaust air from the different areas of the building.
  • a distributor for the supply air for the different areas of the building and / or a collector for the exhaust air from the different areas of the building is available.
  • the invention allows a targeted and energy-efficient promotion of about the supply air into different areas of the building, at the same time as a distributor for the supply air for the different areas of the building is present.
  • the air in the desired Be prepared together. But even if the air is not to be processed at all, but should only come from outside at one point, for example from a green area, a central distributor makes sense.
  • the advantages of decentralized ventilation systems ie the use of individual air conveyors to promote the air in the different areas can be used. More specifically, with a lower energy input than with a central air conveyor, the air can be conveyed to the individual areas as desired.

  • a plurality of air conveyors are provided.
  • Air conveyor provided. This can lead to increased energy consumption in a system according to DE 10 2007 049 333 A1.
  • DE 10 2007 049 333 A1 achieves a reduction of the energy consumption in comparison to systems which have a central air conveying device and at the inlet into the have different areas of the building throttling and thus energy-consuming facilities.

  • Exhaust ducts are preferably arranged in a region in which the supply air ducts and / or the exhaust air ducts are assigned only to a single area of the building.
  • the supply air starting from the manifold can first be performed by common collecting ducts approximately from bottom to top.
  • branches are then arranged from the common collection channel in the Zu Kunststoffkanäle, which are assigned to only a single area of the building. If, in this area of the supply air duct, which is assigned to a single area of the building, an air conveying device is brought about, then it is achieved that the air conveying device supplies just this space with supply air and at least has no appreciable repercussions on other areas of the building.
  • the air handling devices may also be mounted directly adjacent to the different areas of the building to which the individual air handling devices are associated. By mounting in the areas or directly adjacent to the different areas of the building is often a simple installation possible. Further, if necessary, manual adjustment can be made easily.

  • the different areas of the building may be different rooms of the building. This will be very often the case, as often individual ventilation of individual rooms is desired.
  • groups of rooms can be summarized, which are ventilated with a common air conveyor. It is understood that the term space is to be understood widely, including including staircases, atria, common areas, such as in office buildings or the like to be understood.
  • the different areas of the building can also be part areas of larger rooms.
  • the ones assigned to the different areas of the building are assigned to the different areas of the building.
  • Air handling equipment can be designed according to the respective ventilation needs. This should be taken into account different requirements for the amount of air to be delivered.
  • an air conveyor designed for low air flows would be provided.
  • an air conveyor would be used, which larger air flows

  • the respective mode of operation of the air conveying device can be used to adapt to the respective requirement.
  • the air conveying devices are individually controllable. This individual control can be performed manually by a user. But there may also be a regulation, which depends on the desired quality of the air, with C0 2 , VOC or
  • the air handling equipment controls accordingly. If, for example, warm supply air is provided for heating a building, the air conveyor device could automatically be activated in an area in which the temperature is to be increased in such a way that more air is conveyed into this area. More often, the control depends on a measured air quality. As far as the air conveyor has no different power levels, the control is limited to the fact that the air conveyor is turned on when needed.
  • Air conveyors are controlled in different stages and / or a frequency-controlled operation is possible.

So it would be possible for that already mentioned example of an air conveyor for the workplace of a person in an office to provide an air conveyor, which can be operated based on the individual wishes of the person in different performance areas. In most cases, the delivered volume flow is influenced by changing the fan speed. In other areas, such as a staircase, it may be enough, one
